Page 12 Customer Support Chapter 1 A link then, consists of two sites. • In Broadband Wireless terminology, the local and remote sites are sometimes referred to as “near” and “far”, “HQ” and “remote” and so on. The RADWIN 2000 D+ class radios achieve their 700Mbps throughput by drawing on new technology developed for the RADWIN 5000 Point to Multipoint series. Therefore the sites are not symmetrical. The local site referred to earlier, uses a base station radio as the link Master ODU and the remote site uses a subscriber unit as the link Slave ODU. The Master ODU radio is labelled RT‐A(HBS) and the Slave ODU labelled RT‐B(HSU). RT stands for Radio Terminal. The RT‐A(HBS)/RT‐B(HSU) and master/slave terminology will be used throughout the manual both to describe the two link sites without further comment. The link is normally configured and managed using a PC, the managing computer connected to the Master ODU. (The precise requirements for the managing computer are set out in Minimum System Requirements). It may also be connected to the Slave ODU either directly or over‐the‐ air. We will occasionally need to distinguish between the site to which the managing computer is connected, and the second site, when they are not specifically RT‐A(HBS) or RT‐B(HSU). The former will be called the managing site and the latter, the over‐the‐air site. Which is which, is always determined by the location of the managing computer. • Downlink traffic is data transfer from anRT‐A(HBS) to an RT‐B(HSU). • Uplink traffic is data transfer from an RT‐B(HSU) to an RT‐A(HBS). • RADWIN 2000 D+ supports three connection methods for the managing computer: • Local ‐ a direct peer to peer connection between the Ethernet ports on the managing computer and the PoE device. • Network ‐ the managing computer and the site A IDU or PoE device belong to a LAN and communicate through a router or switch • Over‐the‐air ‐ the managing computer connects to site B via the air interface • The managing computer is connected to the link through a PoE device. • Universal bands refer to RADWIN Universal bands.

Page 17 Chapter 3: Site Survey 3.1 Planning the Link Site 3.1.1 Overview Link site planning consists of a set of surveys, which must be carried out before any equipment is brought to the site. If for some reason, the outcome of any of these surveys is negative, site re‐location will need to be considered. A Site Survey consists of three stages: 1. Preliminary survey ‐ The proposed link is analyzed in the office using a topographic map. 2. Physical survey ‐ The locations of the indoor and outdoor equipment are determined on‐ site. 3. Radio Frequency (RF) survey ‐ It is recommended that the installation area be scanned with a spectrum analyzer, to identify RF interference so as to determine a clear channel for radio installation (on‐site). 3.2 The Site Survey 3.2.1 Introduction RADWIN wireless links must be planned before installation. The designated installation site must be appraised to determine that the wireless system is able to operate efficiently and provide connectivity without signal degradation. RADWIN 2000 D+ offers a wide operating frequency range. A free frequency channel must be determined within the operating range, for optimum performance. 3.2.2 Recommended Equipment Stage 1: Preliminary Survey • Topological map of the area • Urban map of the area RADWIN 2000 D+ User Manual Release 3.6.00 3‐1...
Page 18 • GPS device (optional) • Compass (optional) Stage 3: RF Survey • Spectrum Analyzer with Max Hold function and screen capture facility that can store multiple images, for documentation purposes • RF accessories (connectors and cables) • Communication devices (for example, cellular phones, or a set of walkie‐talkies) 3.3 Stage 1: Preliminary Survey A preliminary survey is necessary before visiting potential installation sites. As much detail as possible should be obtained about the two designated ODU installation sites and the area between them.  To perform a preliminary survey: 1. Mark the two designated installation sites on a topographic map of the area. 2. Measure the distance between the sites; check that it is within the specified range of the equipment. 3. On the urban map, check for developed areas situated between the two installation sites. Pay attention to these areas when performing the physical site survey; there may be tall buildings, RF towers, or transmitters, which could cause interference to the link. 4. Check the area between the two sites for obstructions such as: • High ground ‐ hills or mountains • Lakes or large bodies of water. Water has a reflection effect on RF signals like a building. This type of reflection causes the received amplitude to be reduced. As a rule of thumb, the presence of a large body of water between the link sites may double the required antenna height. 5. Determine and record the compass bearings between both ODUs, relative to north. 6. If there are obstructions between the two sites, calculate the Fresnel Zone (see Link Budget Calculator for details). 7. If the site chosen does not meet requirements, consider alternative sites. RADWIN 2000 D+ User Manual Release 3.6.00 3‐2...
Page 19 Stage 2: Physical Survey Chapter 3 8. Use the Link Budget Calculator (on the CD supplied with the equipment or using the RADWIN Manager) to determine the expected performance. 3.4 Stage 2: Physical Survey The physical site survey reviews the environment of the proposed installation location, to ensure that the link sites are suitable for the wireless network. The results of the physical site survey should be recorded. It is advisable to go on a clear day, so you can more easily see any obstructions between the two sites. Note  To perform a physical survey: 1. From the compass readings taken in the preliminary survey, find the azimuth (hori‐ zontal position) that the ODU should face towards the second ODU. 2. Using binoculars, locate any obstructions such as tall trees, high buildings, hills or mountains. Look for other RF towers between the two sites. Mark the locations of the obstructions on the map. 3. Determine the location for the ODU (having regard for existing rooftop installations and tower space). It should be above any obstructions, considering the Fresnel zone (see Link Budget Calculator). 4. If you need to install the ODU on a tower, make sure that the tower is far away from overhead electric power lines. 5. Determine a location for the indoor equipment; it should be as close as possible to the ODU. At an existing site, there is probably an equipment room with cable‐routing channels. The IDU ‐ ODU cable length limit is 100m, in accordance with 10/100BaseT interface. Note 6. Measure and record the path length of the cable from the ODU position to the indoor equipment room. 7. Determine the ground and lightning connection points of the installation. The ODU and IDU must both be grounded. 8. Using the Ohmmeter, measure and record the resistance of the required installation to the grounding point. The resistance must be less than 1O ohm. 9. Review the results of the physical site survey. Decide if the site is suitable for the wireless network installation. • If the site is suitable, continue with stage 3, the RF survey RADWIN 2000 D+ User Manual Release 3.6.00...
Page 20 3.4.1 Additional Outdoor Site Requirements The ambient outdoor operating temperature should be ‐35 to 60C (‐31 to 140F). 3.4.2 Additional Indoor Site Requirements The following requirements guarantee proper operation of the system: • For IDU‐C units, allow at least 90 cm (36 “) of front clearance for operating and mainte‐ nance accessibility. Allow at least 10 cm (4 “) clearance at the rear of the unit for signal lines and interface cables • The ambient operating temperature should be 0 to 50°C (32 to 122 °F) at a humidity of up to 90%, non condensing 3.5 Stage 3: RF Survey The RF survey examines the wireless environment of the installation site, to determine whether there are available channels within the radio operating frequency band. An RF survey is performed using a spectrum analyzer. It is advisable to familiarize yourself with the spectrum analyzer before going out on site, specifically the Max Hold and Marker functions. You should perform the RF survey at both proposed link sites. The survey should be carried out during a busy time of day, to best judge the worst‐case radio interference. Allow 2‐4 hours duration for a good RF survey. It is possible to install the link and use the RADWIN Manager to find a clear channel. Each frequency channel can be evaluated in turn. Achievement of a clear channel is indicated by the marker in the Quality bar on the Channel Note Setting window (see Figure 6‐4) moving into the green area. 3.6 RF Planning for Dense Installations and Collocated Sites Interference may arise from • Self interference from collocated RADWIN radios • Other collocated radio devices installed on the same site. To avoid or minimize interference, follow these recommendations: • For collocated RADWIN units, use an HSS unit to synchronize between them. Select a different operating channels for each collocated RADWIN unit. RADWIN 2000 D+ User Manual Release 3.6.00 3‐4...
Page 21 RF Planning for Dense Installations and Collocated Sites Chapter 3 • If one or more collocated units are not RADWIN units, ensure that there is a physical separation of at least three meters between a RADWIN unit and any other collocated radio on the site. • Use the largest possible frequency gap between these units. • Choose the best frequency channel (as clear as possible form interference). You may have to use the Change Band facility available for all RADWIN 2000 products. • To select a frequency channel, move the link to Installation Mode (using Site configura‐ tion) and start the Installation wizard. In the Channel Settings window, use the quality bar at the bottom to help you choose a better channel (clearer of interference). • Use the Spectrum View tool to find the best working channel (Tools | Spectrum View). • Decreasing the Tx Power of a link will reduce collocation interference (Site Configura‐ tion | Air Interface). Use the Link Budget Calculator to determine the minimum Tx Power required to maintain link stability. Note RADWIN 2000 D+ User Manual Release 3.6.00 3‐5...

Page 36 Installing a Link Chapter 4 Grounding an ODU external antenna External antennas should be individually grounded using a suitable Grounding Kit such as an Andrew Type 223158‐2 (http://www.commscope.com). Grounding the ODU There is a grounding lug on the rear of the HBS as shown in Figure 4‐17. Connect it to ground using 10 AWG wire. Grounding is often carried out in conjunction with lightning protection. Figure 4‐17: ODU: Grounding lug Installing a PoE device The PoE device (Figure 4‐2) is a very simple piece of equipment. It has a recessed three pin AC power plug, a matching power cable, a LAN‐In port (from a switch), a LAN‐Out port (to the HBS) and a power LED, green under normal operation. It is typically strapped into a network equipment rack using plastic ties. It may also sit free on a tray or table‐top. Connecting the ODU to the PoE device Connect the HBS to the LAN‐Out port only. It will not work on the LAN‐In port. RADWIN 2000 D+ User Manual Release 3.6.00 4‐15...
Page 37 The IDU‐H: A Base Station Alternative to PoE Devices Chapter 4 Connecting the PoE Device to a Network Connect the PoE to network equipment such as a switch from the LAN‐In port. Connecting network equipment to the LAN‐Out port may damage it. Powering up the ODU from a Poe Device Connecting the ODU port labelled IDU to a powered up PoE is sufficient. If you have not already closed and weather‐sealed the ODU port marked IDU, then inside it you can see an amber colored power LED which turn green when the ODU is activated. (See Getting Started with the RADWIN Manager.) Mounting the Lightning Protection Units (LPUs) The use of lightning protection is dependent on regulatory and end user requirements. The RADWIN 2000 D+ ODU is designed with surge limiting circuits to minimize the risk of damage due to lightning strikes. RADWIN recommends the use of additional surge arrestor devices to protect the equipment from nearby lightning strikes. The full mounting procedure is show in the LPU Quick Installation Guide, supplied as a hard copy pamphlet. Water Sealing External Ports for CAT‐5e Cables All external ODU ports should be water sealed. 4.5.2 The IDU‐H: A Base Station Alternative to PoE Devices Using an IDU‐H instead of several PoE devices The IDU‐H is an aggregation switch with the functionality of six PoE devices. It is ideal for use at a base station having several collocated ODUs. Figure 4‐18: IDU‐H Installing an IDU‐H The IDU‐H can sit on a table top, but is best installed in a rack using the supplied ears as in Figure 4‐5 and Figure 4‐6.

The plan should specify the precise location and alignment of the radio antennas. The RADWIN 2000 D+ radios are designed to operate in nLOS and NLOS environments so that it is possible that the alignment required may be off‐line of sight. To determine whether the radios communicate as planned you must carry out the first configuration steps described in the next chapter. For users familiar with classic style RADWIN 2000 links: The buzzer method of antenna alignment may not work here both because of the way a link is powered up and also because there is no absolute Note requirement for LOS.

The RADWIN Manager Log‐on Concept Chapter 5 • An Observer has read‐only access to the sector. An Observer can monitor the sector, generate reports, but may not change any sector parameters. • An Operator can install and configure the sector. • An Installer can, in addition to functioning as an Operator, also change the operating frequency band (or regulation). The latter function has legal ramifications, requiring familiarity with local regulations. You may choose the SNMP version. If your firewall blocks SNMPv3 messages and for security reasons cannot be changed them use SNMPv1. If you are using Trap Authentication, enter the User and Password. Leaving these fields blank or incorrect, will not prevent you from logging on. You will not be able to see trap messages directed to the trap message address associated with a defined user.

Page 53 Chapter 6: Link Configuration 6.1 Chapter Contents This chapter is divided into two sections covering the two phases of Link configuration: 1. Link establishment: Initial setup 2. Link maintenance: Fine tuning and special functions Link establishment is typically a once‐only task. Link maintenance is required for fine‐tuning the link and configuration of special features such as VLAN, Quality of Service and more. 6.2 Link Establishment 6.2.1 Link Configuration Workflow The previous chapter showed you how to log on to the RT‐A(HBS). The RT‐A(HBS) requires activation. The ODU will commence transmitting and receiving packets related to link management only ‐ that is no service. Activation and Deactivation are effected quite simply by clicking a toggle button. Assuming that the ODU intended as Link RT‐B(HSU) is mounted aligned and powered up, it will discover the Master ODU establishing a link for management only. At this point the RT‐ B(HSU) may be managed over the air. Having Identified the Link RT‐B(HSU), the latter must be registered to the RT‐B(HSU) to enable traffic between them, completing phase 1. Following registration, you can set separately, • MIMO mode • Transmission ratio between uplink and downlink • Uplink and downlink Maximum Information Rate (MIR) in Mbps • VLAN parameters • Quality of Service parameters. In what follows, we assume that you are logged on to RT‐A(HBS) on IP address as shown in the previous chapter. Here is the opening situation: RADWIN 2000 D+ User Manual Release 3.6.00 6‐1...

Page 90 Management Chapter 7 For a link managed as part of a network, direct access to either site using Telnet is considered to be a security breach. Telnet access may be enabled or disabled by clicking the Protocol tab and enabling/disabling Telnet access using the Telnet check‐box. Similar considerations apply to access via the Web Interface. • For further details about Telnet access see Configuration with Telnet. • For further details about the Web Interface, see Using the Web Interface. Telnet and Web Interface access modes when available, are site specific. If for example, you want Telnet access from a specific site, you should enable it for that sites and disable it for the other. Conversely, If the Telnet or Web Interface access modes pose a general security risk, you must disable them for each site separately.

Management Chapter 7 Figure 7‐13: Alternative Community Dialog box Date & Time The ODU maintains a date and time. The date and time should be synchronized with any Network Time Protocol (NTP) version 3 compatible server. During power‐up the ODU attempts to configure the initial date and time using an NTP Server. If the server IP address is not configured or is not reachable, a default time is set. When configuring the NTP Server IP address, you should also configure the offset from the Universal Coordinated Time (UTC). If there is no server available, you can either set the date and time, or you can set it to use the date and time from the managing computer. Note that manual setting is not recommended since it will be overridden by a reset, power up, or synchronization with an NTP Server. The NTP uses UDP port 123. If a firewall is configured between the ODU and the NTP Server this port must be opened. It can take up to 8 minutes for the NTP to synchronize the ODU date and Note time.  To set the date and time: 1. Determine the IP address of the NTP server to be used. 2.

They are used as an indicator of problems in the radio channel. You can check the RSS from the Link Budget Calculator results during installation. Values of ‐5dB and ‐8dB from the current RSS are typical. TSL Threshold A counter is maintained, of the number of second intervals during which Tx power exceeds this threshold. BBER Threshold The Background Block Error Ratio is measured as a percentage. The threshold can be set from 0.1% up to 50%. An 8% threshold is recommended. If there are no problems during the interval, then for that threshold, the recommended BBER value should be 0. Since the system provides a lossless Ethernet service, there is throughput degradation in case of interference. The degradation is proportional to the BBER.

Page 120 Chapter 9: Hub Site Synchronization 9.1 What is Hub Site Synchronization (HSS) When several radios are collocated at a common hub site, interference may occur from one unit to another. RADWIN ODUs support the collocation of more than two units at a central site. Like any other RF deployment, the wireless operation is highly dependent on factors such as available frequencies, the physical spacing between radios, other third party interfering radios, and whether other RADWIN radios are installed. HSS does not eliminate the need for careful RF planning to ensure the design will work as planned. See Site Survey for information on installation site survey. Note 9.2 RADWIN HSS The RADWIN HSS method uses carries pulses sent to each ODU, which synchronize their transmission with each other. The pulse synchronization ensures that transmission occurs at the same time for all collocated units. This also results in all of the hub site units receiving data at the same time, eliminating the possibility of interference that could result if some units transmit while other units at the same location receive. Figure 9‐1 illustrates interference caused by non‐synchronized collocated units. RADWIN 2000 D+ User Manual Release 3.6.00 9‐1...
Page 121: Figure 9-1 Interference Caused
RADWIN HSS Chapter 9 Figure 9‐1: Interference caused by collocated units Adding HSS removes interference as shown in the next two figures: Figure 9‐2: Collocated units using Hub Site Synchronization (1) Figure 9‐3: Collocated units using Hub Site Synchronization (2) The units are connected to each other with HSS cables and HSS Distribution Units. One of the radios in the site is defined as HSS Master and generates synchronization pulses. The other collocated radios in the site ‐ the HSS Clients, are connected to the HSS Master and synchronize their transmission to the pulses. An HSS Client can be configured to work in one of two modes: RADWIN 2000 D+ User Manual Release 3.6.00 9‐2...
Page 122 RADWIN HSS Chapter 9 • HSS Client‐Continue Transmission (HSC‐CT): If the unit loses synchronization with the HSS Master, the link remains active. However, without synchronization pulses, it is pos‐ sible that this unit will cause interference. • HSS Client‐Disable Transmission (HSC‐DT): If the unit loses synchronization with the HSS Master, the link is dropped until the synchronization pulses resume. This setting prevents the unit from causing interference. The remote ODUs that are not located at the hub site, are called Independent Units (INU). RADWIN offers two types of HSS: » Serial HSS The RADWIN Serial Hub Site Synchronization (SHSS) method uses a cable connected from the master ODU to all collocated ODUs; this cable carries pulses sent to each ODU, which synchronize their transmission with each other. SHSS is covered in Serial Hub Site Synchronization. » Ethernet HSS The Ethernet HSS (HSSoE) method requires Layer 2 Ethernet connectivity between collocated ODUs. It has two requirements: • Collocated ODUs providing Ethernet services only, should be connected to an IDU‐H instead of regular PoE devices. Other simple switches may work with degraded per‐ formance. They are not recommended and problems arising from their use will not be eligible for any kind of support. • Collocated ODUs providing E1/T1 services should use an IDU‐C or IDU‐E and then be connected to an IDU‐H functioning as a switch. One of the LAN ports on the IDU‐C or IDU‐E is connected to any of the six IDU‐H PoE ports or the two LAN ports. (This is possible because the IDU‐C or IDU‐E LAN cable only uses four pins for data; the power pins are not used so there is no risk of damage to them.) In this way, up to eight such ODUs may be collocated. You may only use one IDU‐H. That is, they may not be cascaded. Note If you are using an IDU‐C0 (GbE) it must be connected to the IDU‐H LAN port only. Connecting it to the PoE ports will damage the unit and in any event, it will not work.

HSS Concepts: Radio Frame Pattern (RFP) Chapter 9 9.3 HSS Concepts: Radio Frame Pattern (RFP) A Radio Frame Pattern (RFP) is the cycle duration of transmit and receive of the air‐frame. 9.3.1 Without HSS When selecting TDM or Ethernet services, the system automatically and transparently chooses the optimal RFP. When TDM and Ethernet services are configured, the RFP is optimized for TDM. 9.3.2 RFP and HSS When HSS is used, the RFP for the collocated radios must be selected manually. RADWIN 2000 uses the Time Division Duplex (TDD) mechanism. Under HSS, TDD enables synchronization of transmission for the collocated units as shown in Figure 9‐4: Figure 9‐4: Radio Frame Pattern Two RFP types (labelled B and E) are available. Under HSS the RFP must be configured by the user depending on the type of the radio products, services and channel bandwidth in accordance with Table 9‐2. The table describe the efficiency of the air interface according to the RFP type, services and channel bandwidth. The tables may also be viewed in the RADWIN Manager and in the Link Budget Calculator. The efficiency of the air interface will vary according to the product used.

The RFP must be the same for each link within the collocated system. Note 9.3.3 RFP: General Radio Frame Pattern When setting the RPF, the following considerations should be borne in mind: • When synchronizing RADWIN 2000 D+ or RADWIN 5000 units you must use RFP E • When synchronizing RADWIN 2000 D+ or RADWIN 5000 with RADWIN 2000 or Airmux‐ 200 units you must use RFP E • RFP influences capacity and latency. • Using the Link Budget Calculator, you can see the effect of the RFP on the Ethernet throughput. 9.4 Which Type of HSS to Use You may use both forms of HSS with an RT‐A(HBS). There are however some limitations: • If you collocate an RT‐A(HBS) to both a unit supporting SHSS and HSSoE, the RT‐A(HBS) must always be HSM • If you collocate with a GSU, you can only use HSSoE and the GSU mast be HSM.

Page 125 Chapter 10: Serial Hub Site Synchronization 10.1 RADWIN Serial HSS The RADWIN Serial Hub Site Synchronization (SHSS) method uses a CAT 5e cable connected from the master ODU to all collocated ODUs; this cable carries pulses sent to each ODU, which synchronize their transmission with each other. Since the SHSS unit is still shown in the RADWIN Catalog as an “HSS unit”, in the remainder of this chapter we will continue with this convention on the clear understanding that we are dealing only with SHSS. 10.2 Hardware Installation 10.2.1 Connecting an HSS Unit A single HSS unit supports up to ten collocated ODUs. In addition to each unit being connected to its IDU or PoE device, the collocated unit has an additional cable that is connected to the HSS Unit. The HSS Unit is a compact, weatherproof (IP67) connector box that is installed on the same mast as the ODUs. All collocated units connect to this box using CAT‐5e cable. Cables in prepared lengths are available for purchase. The HSS unit is supplied with ten protective covers; any port not in use must be closed with a protective cover. RADWIN 2000 D+ User Manual Release 3.6.00 10‐1...
Page 126 Connecting an HSS Unit Chapter 10 Figure 10‐1: HSS Interconnection Unit • For a single HSS unit, ensure that the collocated units are connected in sequence from SYNC 1. If an ODU is removed from the hub site, then all remaining ODUs must be reconnected to maintain the connectivity. • You may cascade (daisy‐chain) two or more HSS Units with an HSS Note cable. The method is described in detail below.  To connect an ODU to an HSS unit: 1. Unscrew the protective cover from the port marked SYNC 1. 2. Connect the RJ‐45 connector from one end of the prepared CAT‐5e cable to SYNC 1. 3. Connect the other end of the CAT‐5e cable to the ODU connector labeled SYNC. 4. Tighten the protective seal that is on the prepared cable over the RJ‐45 connector. 5. Repeat for all ODUs that are to be collocated at the hub site. The next ODU to be connected is inserted in SYNC 1, SYNC 2, followed by SYNC 3 and so on. RADWIN 2000 D+ User Manual Release 3.6.00 10‐2...
Page 127: Figure 10-3 Hss Sync Signal
Using a Single HSS Unit Chapter 10 10.2.2 Using a Single HSS Unit Figure 10‐2: HSS Wiring schematic The wiring, as shown in Figure 10‐2 is self explanatory. The Sync signal path is less self evident. If we set ODU 1 (on SYNC 1) to HSS Master, then the Sync signal path is as shown in Figure 10‐3. The signal travels from ODU 1 to SYNC 1, from SYNC 1 to SYNC 2, from SYNC 2 to ODU 2 and back again. The back and forth paths repeat for the second to fourth ODU, from left to right. The signal exits the HSS unit at SYNC 5 and terminates in ODU 5. The choice of the ODU on SYNC 1 as HSS master is not mandatory, but is good practice. If for example we were to use ODU 3 as HSS master, the Sync signal path would be ODU 3 to SYNC 3, then left and right to SYNC 2 and SYNC 4. It would then propagate to ODUs 2 and 4, terminating at both ODUs 1 and 5.

Sync signals are exchanged between collocated radios over the regular Ethernet connection. The Ethernet HSS (HSSoE) method requires Layer 2 Ethernet connectivity between collocated ODUs. It has two requirements: • Collocated ODUs providing Ethernet services only, should be connected to an IDU‐H instead of regular PoE devices. Other simple switches may work with degraded per‐ formance. They are not recommended and problems arising from their use will not be eligible for any kind of support. • Collocated RADWIN 2000 class ODUs providing E1/T1 services should use an IDU‐C or IDU‐E and then be connected to an IDU‐H functioning as a switch. One of the LAN ports on the IDU‐C or IDU‐E is connected to any of the six IDU‐H PoE ports or the two LAN ports. (This is possible because the IDU‐C or IDU‐E LAN cable only uses four pins for data; the power pins are not used so there is no risk of damage to them.) In this way, up to eight such ODUs may be collocated. You may only use one IDU‐H. That is, they may not be cascaded. Note If you are using an IDU‐C0 (GbE) it must be connected to the IDU‐H LAN port only. Connecting it to the P0E ports will damage the unit and in any event, it will not work.

Page 134 HSSoE Concepts Chapter 11 VLAN Tagging should not use the VLAN ID used by HSSoE and vice versa. Caution 11.1.2 HSSoE Concepts ODUs For HSSoE purposes, an ODU is any RADWIN radio supporting it. Currently, these include RADWIN 5000, RADWIN 2000 D+ RT‐A(HBS) and RADWIN Jetb ase station units. Sync Frames Sync frames are exchanged between collocated ODUs using Layer‐2 broadcasting. Domain To prevent network flooding, each group of collocated ODUs is configured with an internal “domain name”. The default name must be changed to prevent sync frames being received over the LAN by another ODU, which could be then mistakenly configured as a client of an HSM at the wrong location. Discovery Discovery by the HSM and HSCs is provided using the following choice of filters: RADWIN 2000 D+ User Manual Release 3.6.00 11‐2...
Page 135 HSSoE Concepts Chapter 11 Using discovery at the HSM, you can select only those HSCs in the HSM’s domain; when configuring a new HSC you may use discovery to pick the correct HSM. VLAN VLAN is used to separate sync frames from traffic so as to give sync frames highest priority. If you have collocated ODUs running close to full capacity, failure to do so, would result in excessive jitter and dropped traffic frames. By default, the VLAN ID 1997 and priority 7 are reserved for HSS. You may change the VLAN ID but not the priority. RADWIN 2000 D+ User Manual Release 3.6.00 11‐3...

The IDU‐H has two LAN ports, one of which will be connected to a switch. 11.2.2 Ethernet and TDM Services For RADWIN 2000 class ODUs: To attain Layer 2 connectivity for up to two such ODUs, you should connect one of the two the IDU‐C (or IDU‐E) LAN ports to the IDU‐H LAN ports. You may use the second IDU‐C (or IDU‐E) LAN port to connect to a switch. As pointed out earlier, you may only collocate two ODUs in this way. 11.3 Link Configuration and HSSoE 11.3.1 Setup for Illustration We will show how to set up our demonstration link as HSM and HSC in turn.

Page 144 Chapter 12: Using the GSU 12.1 What is it for The GPS‐based synchronization unit (GSU) is designed to handle inter‐site interferences under large‐scale deployment scenarios. The GSU is an outdoor unit consisting of a small size enclosure, a GPS antenna and a PoE device. It may be operated through an HSS unit or over Ethernet. For use over Ethernet, the GSU requires Layer 2 connectivity to the multiple Hub‐Sites that it is required to synchronize. It synchronizes the transmission timing of these Hub‐Sites to the same clock source thus eliminating mutual interference. Typically, an IDU‐H is used.

It distributes a RADWIN proprietary synchronization signal to all other ODU units using a proprietary synchronization signal over Ethernet. When the GSU doesn’t receive a synchronization signal from the GPS for 30 seconds, it moves automatically to Self‐Generation mode until the GPS recovers. 12.3 GSU Kit Contents The GSU package includes: • 1 x GSU • 1 x GSU Mounting Kit • 1 x GPS Antenna • 1 x GPS Antenna Mounting Kit RADWIN 2000 D+ User Manual Release 3.6.00 12‐2...

Page 161 Chapter 15: VLAN Functionality 15.1 VLAN Tagging ‐ Overview 15.1.1 VLAN and Related Terminology Both the technical literature and the RADWIN Manager use the terms VLAN ID and VID interchangeably to denote a VLAN identification number. The VLAN implementation for RADWIN 2000 D+ is based on that of RADWIN 5000 so the latter ODU terminology is retained. Recall, that HBS always means the Master ODU and HSU always means the Slave ODU. 15.1.2 VLAN Background Information on the Web The standards defining VLAN Tagging are IEEE_802.1Q and extensions. For general background about VLAN see http://en.wikipedia.org/wiki/Virtual_LAN. Background information about Double Tagging also known as QinQ may be found here: http://en.wikipedia.org/wiki/802.1QinQ. 15.2 Scope of this Chapter This chapter describes how the components of a RADWIN 2000 D+ link deal with tagging and untagging. 15.3 Requirements It is assumed that you are familiar with VLAN usage and terminology. 15.4 VLAN Tagging VLAN tagging enables multiple bridged networks to transparently share the same physical network link without leakage of information between networks: RADWIN 2000 D+ User Manual Release 3.6.00 15‐1...
Page 162 QinQ (Double Tagging) for Service Providers Chapter 15 IEEE 802.1Q is used as the encapsulation protocol to implement this mechanism over Ethernet networks. 15.4.1 QinQ (Double Tagging) for Service Providers QinQ is useful for Service Providers, allowing them to use VLANs internally in their “transport network” while mixing Ethernet traffic from clients that are already VLAN‐tagged. The outer tag (representing the Provider VLAN) comes first, followed by the inner tag. In QinQ the EtherType = 0x9100. VLAN tags may be stacked three or more deep. When using this type of “Provider Tagging” you should keep the following in mind: • Under Provider Tagging, the system double‐tags egress frames towards the Provider’s network. The system adds a tag with a VLAN ID and EtherType = 0x9100 to all frames, as configured by the service provider (Provider VLAN ID). • The system always adds to each frame, tags with VLAN ID and EtherType = 0x9100. Therefore, • For a frame without a tag – the system will add a tag with VLAN ID and EtherType = 0x9100 so the frame will have one tag • For a frame with a VLAN tag – the system will add a tag with VLAN ID and EtherType = 0x9100 so the frame will be double‐tagged For a frame with a VLAN tag and a provider tag – the system will add a tag with VLAN ID and EtherType = 0x9100 so the frame will be triple‐tagged and so on. At the egress side, the RT‐B(HSU) removes the QinQ tag with EtherType = 0x9100 no matter what the value of its VLAN ID. 15.4.2 VLAN Untagging VLAN Untagging means the removal of a VLAN or a Provider tag. 15.4.3 Port Functionality In a RADWIN 2000 D+ link, all VLAN activity is configured and supported from the RT‐B(HSU). To this end, VLAN functionality is supported at the LAN port of the RT‐B(HSU). The RT‐B(HSU) LAN port can be configured to handle Ethernet frames at the ingress direction (where frames enter the RT‐B(HSU)) and at the egress direction (where frames exit the RT‐ B(HSU)).

Under no circumstances Disclaimer does RADWIN accept responsibility for network system or financial damages arising from incorrect use of these VLAN facilities. 15.5.1 Management Traffic and Ethernet Service Separation You can define a VLAN ID for management traffic separation. You should configure the system to prevent conflicts as detailed below. When configured for the default operational mode, a “Provider port” will handle ingress traffic as follows: • Filters frames that are not tagged with the Provider VLAN ID • Removes the Provider double tag Therefore, if a port is configured for management traffic separation by VLAN and as ‘Provider port’, then the received management frames must be double tagged as follows: RADWIN 2000 D+ User Manual Release 3.6.00 15‐4...
Page 165 Configuration of VLAN Tagging for Ethernet Service Chapter 15 • The outer tag has to be the Provider’s tag (so the frame is not filtered) • The internal tag has to be management VLAN ID To avoid mix‐ups, best practice is to: • Separate the management and data ports • Define only a data port with Provider function 15.5.2 Configuration of VLAN Tagging for Ethernet Service  To set up an HSU for VLAN tagging: 1. Open Link Configuration | Ethernet and then click the VLAN Configuration button. In Disabled mode, Ethernet frames pass transparently over the radio links. 2. For Provider tagging, click the Provider Radio button: In Provider mode, Ethernet frames are tagged with the provider’s VLAN ID before they enter into the provider’s network/backbone.

Page 170 Assigning Queue Priorities Chapter 16 If you un‐check a queue, it will be disabled for the link. It will not prevent the Slave ODU from configuring it as “live”. The purpose behind this is to avoid the necessity of reconfiguring QoS for the Slave ODU, should the queue be reinstated. 16.3.2 Assigning Queue Priorities Four mechanisms are available to control queue performance: • Strict ‐ An over‐the‐air packet is loaded first with data from Real Tome queue (see Figure 16‐2), and then from the remaining queues in order. If there is too much data for the first queue, it will “starve” the lower queues and so on. • Weight ‐ One solution to such “starvation” is to weight input flow to the four queues. This could still lead to wasted resources. If in the example below, the actual traffic is all Near Real Time, only 20% will be allocated to Near real time and the rest will be held up. • Maximum Information Rate (MIR) ‐ This is a simple throttle mechanism, which suffers from a drawback similar to the previous case. • Time to Live (TTL) in ms ‐ This device is use to reduce re‐transmits of real time data (such as voice or viewed video).

Page 171: Figure 16-2 The Four Q Os
Assigning Queue Priorities Chapter 16  To configure queue priorities for uplink and downlink in turn: 1. For each queue, both downlink and uplink enter the required weight, MIR and TTL. The MIR and TTL may respectively be left Unlimited and Disabled in which case the system will use a “best effort” method. If you exceed 100% total weight, you will receive an error message. Figure 16‐2: The four QoS data queues You will be required to correct this before leaving the window other than by cancel‐ lation. If you are under‐booked, for example by setting a queue to zero, the unused weight will be distributed to the remaining queues. The effect of doing this will only become apparent under congestion. In particular, a queue set to zero weight will become nearly blocked under congestion with packets passing through on a best effort basis. 2. When you complete your entries, in the QoS Configuration window (Figure 16‐1), click OK to save them and continue. RADWIN 2000 D+ User Manual Release 3.6.00 16‐4...
Page 172 Chapter 17: False Radar Mitigation Facilities 17.1 Who needs it If you are using DFS frequency bands 5.3/5.4 GHz ETSI and 5.4/5.8GHz FCC you should use this facility. 17.2 DFS and False Radar Mitigation 17.2.1 About DFS Under DFS frequency bands, it must be ensured that radio links do not interfere with certain radar systems in the 5 GHz band. If radar is detected, the radio link should move automatically to a frequency that does not interfere with the detected radar. 17.2.2 What is False Radar Mitigation False Radar Mitigation capability is an advanced method to reduce or eliminate false radar detection and DFS triggering (“False positives”). False radar detection can be caused by other radios transmissions or external interference that can be interpreted as true radar. This option is active only in DFS frequency bands, 5.3/5.4 GHz FCC (HBS only) and 5.4/5.8GHz ETSI (HBS & HSU). In what follows false radar means any source of radar‐like signals which are not real radar. False Radar Mitigation has two components: 1. Reduction of false positive radar detection by reduction of the probability of detecting any kind of false radars, while allowing the system to detect real radar signals. 2. Elimination of detection of specific false radar types by blocking detection of false radars of a specific type. There are three types of radars: • Fixed: False radars with fixed pulse width having fixed repetition frequency RADWIN 2000 D+ User Manual Release 3.6.00 17‐1...

The FCC has published a TDWR Location Information table that lists the exact location of all TDWR towers (see Table 18‐1 at the end of the chapter). 1. When installing a 5.4 GHz device define your exact location (latitude and longitude) 2. Use the TDWR Location Information table to determine if the distance between the device and any TDWR tower is less than 35 km. 3. If the distance is less than 35 km then register the device in the voluntary WISPA sponsored database (following section) 4. Disable the frequencies between 5570 – 5680 MHz from the available channels list. 5. The frequency range between 5.600 to 5.650 GHz is not included in the available channels list. 18.2 Registering the Device  To register a device: 1.

Page 182 Chapter 19: Link Budget Calculator 19.1 Overview The Link Budget Calculator is a utility for calculating the expected performance of the RADWIN 2000 D+ wireless link and the possible configurations for a specific link range. The utility allows you to calculate the expected RSS of the link, and find the type of services and their effective throughput as a function of the link range and deployment conditions. 19.1.1 User Input You are required to enter or choose the following parameters. Depending on the product, some of the parameters have a default value that cannot be changed. • Band, which determines frequency and regulation • ODU series used • Channel Bandwidth • Tx Power (maximum Tx power per modulation is validated) • Antenna Type (currently dual; cannot be changed for ODU with integrated antenna) • Antenna Gain per site (cannot be changed for integrated antenna) • Cable Loss per site (cannot be changed for integrated antenna) • Fade Margin (currently 6dB) • Rate • Required Range and climate type 19.1.2 Link Budget Calculator Internal Data For each product (or Regulation and Band) the calculator stores the following data required for link budget calculations: • Maximum Transmit power (per modulation) • Receiver Sensitivity (per modulation) for Ethernet service • Maximum linear input power (used to calculate minimum distance) • Antenna gain and cable loss for ODU with integrated antenna •...

Page 185: Figure 19-1 Fresnel Zone
About the Fresnel Zone Chapter 19 Figure 19‐1: Fresnel zone Fresnel loss is the path loss occurring from multi‐path reflections from reflective surfaces such as water, and intervening obstacles such as buildings or mountain peaks within the Fresnel zone. Radio links should be designed to accommodate obstructions and atmospheric conditions, weather conditions, large bodies of water, and other reflectors and absorbers of electromagnetic energy. The Fresnel zone provides us with a way to calculate the amount of clearance that a wireless wave needs from an obstacle to ensure that the obstacle does not attenuate the signal. There are infinitely many Fresnel zones located coaxially around the center of the direct wave. The outer boundary of the first Fresnel zone is defined as the combined path length of all paths, which are half wavelength (1/2 ) of the frequency transmitted longer than the direct path. If the total path distance is one wavelength (1 ) longer than the direct path, then the outer boundary is said to be two Fresnel zones. Odd number Fresnel zones reinforce the direct wave path signal; even number Fresnel zones cancel the direct wave path signal. The amount of the Fresnel zone clearance is determined by the wavelength of the signal, the path length, and the distance to the obstacle. For reliability, point‐to‐point links are designed to have at least 60% of the first Fresnel zone clear to avoid significant attenuation. The concept of the Fresnel zone is shown in Figure 19‐1 above. The top of the obstruction does not extend far into the Fresnel zone, leaving 60% of the Fresnel zone clear; therefore, the signal is not significantly attenuated. For more about Fresnel zone, see http://en.wikipedia.org/wiki/Fresnel_zone. RADWIN 2000 D+ User Manual Release 3.6.00 19‐4...

Page 193 Chapter 20: Spectrum View 20.1 What is Spectrum View The RADWIN Manager Spectrum View utility is an RF survey tool designed to support the link installation prior to full link service activation. The tool provides comprehensive and clear spectral measurement information enabling easier, faster and better quality installations. You can view real‐time spectrum information, save the spectral information and view retrieved spectral information from historic spectrum scans. Separate information is generated for the Slave and Master ‐ all by selection. RADWIN’s spectrum measurement and estimation algorithms are designed to show accurate information accommodating variations in frequency, temperature and interference power and at the same time overcoming anomalies that tend to occur in high interference environments. 20.2 Who needs it As indicated in the previous paragraph, Spectrum View is primarily a professional tool for the technician. The Spectrum View reports may be generated as images, CSV files or text files as part of the Get Diagnostics feature. All of these are intended for use by to RADWIN Customer Service to assist with diagnosing interference related problems. 20.3 Scope of this Chapter In view of the nature of the intended audience, we assume that the reader knows about RF Spectrum Analysis. This chapter therefore, is not a tutorial on RF Spectrum Analysis and is restricted to showing how to use the Spectrum View tool without any further theoretical explanations. 20.4 Two Ways to Run Spectrum View Spectrum View may be run from RT‐A(HBS) in which case you have a choice of analyzing both sites in the link in one run, or choosing just one. RADWIN 2000 D+ User Manual Release 3.6.00 20‐1...
Page 194 Where is the Spectrum View Data stored Chapter 20 Spectrum View may also be run on a managing computer directly connected to the RT‐ B(HSU). Remember that in such a case the results will be quite different if the RT‐B(HSU) is already part of a link (registered or not) or if it is completely stand‐alone, for example using a different spectral range and operating Band from the RT‐A(HBS). In the former case, expect a “noise hump” around the channels used by the link, due to the duty signals from the RT‐ A(HBS). 20.5 Where is the Spectrum View Data stored Spectrum View data is always stored in the ODU originating the analysis. The RT‐A(HBS) maintains the last Spectrum View analysis data for both members of the link. If you run Spectrum View from a directly connected ODU, it stores its own data, which may be quite different from the analysis obtained for the same RT‐B(HSU) from the RT‐A(HBS). 20.6 Spectrum View Main Window In this section we review the main window management controls.

Page 200 Chapter 21: Using the Web Interface 21.1 What is it For The Web Interface (WI) enables you to carry out basic link management functions using a Web browser. It may be used to ‐ • Monitor a link on a minimal basis • Check link parameters and make limited changes • View the link Inventory • Inspect the Recent Events logs 21.2 Who Needs it The WI is a tool for technicians to “quick‐install” an ODU in a link with minimum effort. It may also be employed by a user for a quick look at current operating parameters and the Recent Events logs. 21.3 How it Works Assume the link setup, which we used in and later. Link Configuration On the managing computer, point your browser to10.104.4.2 and log on as shown below. You can also log on over the air to the Slave ODU in the same way. For stand‐alone or unregistered ODUs, you must connect a managing computer directly to the ODU and again log on as shown below. 21.4 What it Provides The WI is a developing technology. It is possible that the current distributed release may have additional or slightly different features from those shown here.

The WI can be used directly opposite the HBS any of its HSUs. It can also be used over the air from the HBS to any registered HSU. 21.5.2 Software Your computer should have at least version 6 of MS Internet Explorer. The Web interface also works with other browsers such as Mozilla Firefox version 3 and later. 21.5.3 Technical Background You should be familiar with the concepts underlying the RADWIN Manager and preferably with the Manager itself. 21.6 Special Considerations Working with the 21.6.1 Advanced Configurations For setup configurations using features such as HSS, VLAN and QoS, you will need to use the RADWIN Manager. 21.6.2 Operational Effects Several WI functions cause temporary sync loss. Typically, changing the number of antennas falls into this category. These cases will be pointed out in Warning messages. 21.6.3 Some Working Tips You can: » Log on to a ODU on the default IP address of 10.0.0.120/8, set the Link ID and IP address instead of using the RADWIN Manager as in Getting Started with the RADWIN Manager. Unlike the Local Connection method, you need to reset the ODU to see the change in the Web Interface. » Change the operating Band for the link instead of using the RADWIN Manager.

Page 212 Appendix B: Setting Antenna Parameters B.1 Antenna Issues The choice of Tx Power, antenna gain and cable loss (between the radio and the antenna) determines the EIRP and is affected by such considerations as radio limitations and regulatory restrictions. Before proceeding to antenna installation details, the following background information should be considered: B.2 About Single and Dual Antennas Each RADWIN 2000 D+ ODU is made of two radio transceivers (radios). The radios make use of algorithms that utilize both Spatial Multiplexing and Diversity resulting in enhanced capacity, range and link availability. The number of antennas (i.e. radios) used is determined by user configuration and by automatic system decisions, explained below. B.2.1 Dual Antennas at the HBS and an HSU When using dual antennas at both sites (single bipolar antenna or two unipolar antennas) you can choose between Spatial Multiplexing Mode and Diversity Mode. Spatial Multiplexing Mode Under this mode, the system doubles the link capacity. At the same time, it keeps the same rate and modulation per radio as was used with single antenna, thus increasing capacity, range and availability. For example, at 80MHz CBW, using a dual antenna RADWIN 2000 D+ can transmit at modulation of 256QAM and FEC of 5/6 and get an air rate of 866.7 Mbps, compared to 433.3 Mbps with single antenna. To work in this mode, each antenna port must be connected to an antenna, the RSS level in both receivers should be balanced and a minimal separation between the antennas must be RADWIN 2000 D+ User Manual Release 3.6.00 B‐1...
Page 213 Single Antennas at Both Sites Chapter B maintained. (For example, by using dual polarization antennas a cross polarization separation is attained). Upon selecting Antenna Type as Dual, RADWIN 2000 D+ automatically selects this mode and doubles the air rates. RADWIN Manager indicates a case of unbalanced RSS between the two antennas in the center panel. Diversity Mode Diversity Mode uses two antennas to improve the quality and reliability of the link. Often, there is not a clear line‐of‐sight (LOS) between transmitter and receiver. Instead the signal is reflected along multiple paths before finally being received. Each such “bounce” can introduce phase shifts, time delays, attenuations, and even distortions that can destructively interfere with one another at the aperture of the receiving antenna. Antenna diversity is especially effective at mitigating these multi‐path situations. This is because multiple antennas afford a receiver several recordings of the same signal. Each antenna will be exposed to a different interference environment. Thus, if one antenna is undergoing a deep fade, it is likely that another has a sufficient signal. Collectively such a system can provide a robust link. Antenna diversity requires antenna separation which is possible by using a dual‐polarization antenna or by two spatially separated antennas. Use Diversity instead of Spatial Multiplexing in the following situations: • When the system cannot operate in Spatial Multiplexing Mode • When one of the receivers has high interference compared to the second receiver (i.e. the system is “unbalanced”) • When you achieve higher capacity in Diversity Mode than in Spatial Multiplexing Mode • When high robustness is of importance and the capacity of Diversity Mode is sufficient (up to 25 Mbps full duplex) B.2.2 Single Antennas at Both Sites By selecting a single antenna at both sites, the ODUs operate with a single radio that is connected to the ANT 1 connector. The second radio is automatically shut down. B.2.3 Single at One Site, Dual Antennas at the Other In this mode one of the sites uses the ODU with a single antenna while the other site uses the ODU with a dual antenna. The advantages in this mode in comparison to using a single antenna in both sites are doubled total Tx Power and additional polarization and/or space diversity (depending on the ...
