Trango Systems, Inc TL45 User Manual Rev 2.0r3 Chapter 1 Overview The TrangoLINK‐45 is a point‐to‐point (PtP) wireless Ethernet transmission system which provides network connectivity at speeds up to 45 Mbps depending on the transmission distance and noise floor. The TrangoLINK‐45 utilizes OFDM technology and is designed for use in long range backhaul and wide area data networking applications. Users are required to simply specify one P5055M unit type as master unit (MU) and one unit as remote unit (RU) to establish a link. Each unit utilizes power‐over‐Ethernet (PoE) and is designed for outdoor environments. The cable entry point can accommodate both Shielded twisted pair Cat5 (STP) and unshielded twisted pair Cat5 (UTP), with the addition of conduit for tower mounting. DFS One of the key features of the TrangoLINK‐45 is that it has Dynamic Frequency Selection (DFS) which allows it to be operated in the 5.25 to 5.35 GHz and 5.47 to 5.7 GHz frequency ranges depending upon the regulatory requirements. When operating in these frequencies ranges the MU will monitor the channel for radar transmissions and switch to a new channel automatically if radar is detected. The RU will switch to the new channel as well and the link will be automatically reconnected, typically in about 1 minute. Each radio unit has a different threshold for detecting radar that corresponds to the radio’s antenna gain. For the P5055M‐19‐xx models, the threshold is –46 dBm. Any radar signal arriving at the antenna on the operating channel that has an amplitude greater than –46 dBm will cause the MU and it’s associated RU to switch to a randomly selected channel that is tagged as a DFS channel in the channel table. For the P5055M‐23‐xx units, the threshold is is –42 dBm, and for the P5055M‐EXT‐xx units the threshold is –37 dBm. IMPORTANT NOTE: When operating in the DFS frequencies, the radio units will use automatic transmit power control (ATPC) to maintain the RSSI at a level of approximately –62 dBm. For very short link distances it may not be possible for the transmit power to be reduced below the Radar detection threshold and the radio may not be able to establish a reliable link. Trango recommends that careful link budget planning be done to ensure that this condition does not exist. OFDM The TrangoLINK‐45 platform utilizes Orthogonal Frequency Division Duplex (OFDM) processing which offers link stability and performance in the presence of multipath interference. Adaptive Modulation One of the key advantages of the TrangoLINK‐45 series radio platform is utilization of multiple modulation schemes including the following: Binary Phase Shift Keying (BPSK) ...
Trango Systems, Inc TL45 User Manual Rev 2.0r3 ARQ Another key advantage of the TrangoLINK‐45 platform is its Automatic Repeat Request (ARQ) transmission correction scheme. The ARQ algorithm detects packet loss due to fading and interference conditions and requests the remote radio to re‐transmit specific packets. Dual Polarity Antenna TrangoLINK‐45 radios feature built‐in dual polarity antenna functionality. Users may select either horizontal or vertical antenna polarity through the unit’s software. The feature of selecting antenna polarity provides greater spectral flexibility and ability to mitigate interference. LT‐9037A August 15, 2011 Page 9 ...

Trango Systems, Inc TL45 User Manual Rev 2.0r3 Chapter 2 Getting Started It is always a good idea to first provision and test the radios on the bench before deploying them in the field. This is a particularly useful exercise for the first time user. Connections and Power • Connect a Cat‐5 (straight through) Ethernet cable (we recommend shielded twisted pair) between the ODU (out door unit) port of the J‐box and the RJ‐45 connector on the radio. Note that this cable will carry power‐ over‐ Ethernet (PoE). • If connecting to a COMPUTER, use a Cross‐Over Ethernet cable from the NET port of the J‐box to the computer’s Ethernet port. If connecting to a HUB, SWITCH, or ROUTER, use a Straight‐Thru cable. Plug the AC adapter into an AC outlet. • Both green LEDs on the J‐box should be lit, indicating power is present at the Power‐over‐Ethernet box as well as at the radio. You are now ready to configure the radio via the Ethernet port. After reboot, the Radio Power LED may take several seconds before lighting. The radio requires approximately 45 seconds to boot.

Trango Systems, Inc TL45 User Manual Rev 2.0r3 Chapter 3 Configuration Key Concepts Prior to configuring the radios it is important to understand several key concepts: Master Unit (MU) The MU is typically considered the primary radio within the link. For management purposes it is recommended to install the MU closest to the head‐end of the network. Remote Unit (RU) The RU is typically installed at the remote end of the link. The primary distinction between the MU and RU is that when the radios are not associated, the MU will transmit and the RU will listen until the wireless link is established. Peer ID The Peer ID is defined as the MAC address of the opposite radio. In other words, the Peer ID of the MU is the RU’s MAC address and the Peer ID of the RU is the MU’s MAC address. Authentication is controlled by the MAC address of each radio. Opmode The radio has two modes of operation: 1) Opmode OFF – The radio is in a state which will not allow the establishment of a link with another radio. This state is mainly used for administration and pre‐ installation site survey 2) Opmode ON – The radio is in a state which allows it to establish a link to another radio if the proper settings are made. This is the normal “in service” state of the radio. Default Opmode Opmode (on or off) which the radio enters after reboot. Note: if you telnet into a radio within 30 seconds after reboot, the radio will remain in opmode OFF even if the default opmode is ON. ...
Trango Systems, Inc TL45 User Manual Rev 2.0r3 Master Unit Configuration Start a telnet session with one of the radios. Follow these steps for configuration. 1. Set the Unit Type (utype) to MU in one radio. (default for all radios is RU) #> utype mu Success. #> 2. Set the Peer ID with the MAC address of the RU.

Trango Systems, Inc TL45 User Manual Rev 2.0r3 Yellow LED 4 : Begins blinking when RSSI is greater or equal to –60 dBm. On solid at –55 dBm. This is the rightmost LED. If no VALID MU or RU signal is detected the LEDs will not be on at all. In addition, these 4 LEDs shall flash ON for 2 seconds, then OFF for 2 seconds to indicate the 'factory reset' button has been activated and the reset successful. ASSOCiation LED (green): The ASSOC led blinks at the following rates: ‐ Once every second when unit is powered on but opmode is OFF. ‐ Twice per second while in opmode ON and scanning for an MU or RU. ‐ Solid after unit is associated with the RU or MU. RF Link Loopback Test (linktest command) The linktest command is the primary tool to assess the quality of the link when opmode is on. The linktest command tests the throughput and packet error rate (PER) on the current channel for each direction at all speeds and reports results. This command also provides RSSI for both ends of the wireless link. The command can be run from either the MU or the RU. The linktest uses FEC but does NOT use ARQ, so all errors on the link are reported. Throughput numbers represent the absolute maximum bi‐directional capacity including the management header (which is not available for user payload) so actual user throughput measurements will be slightly less. In running the linktest command the user must specify the modulation speed for each end of the link. Command format: linktest <loc speed> <peer speed>. Valid modulation speeds are: 6, 12, 18, 24, 36,48, and 54 Mbps. Lower speeds will result in fewer dropped packets. Example: # linktest 24 24 local tx rate = 24 Mbps peer rate = 24 Mbps packet size = 1600 bytes...
Trango Systems, Inc TL45 User Manual Rev 2.0r3 Link Speed & Power Settings Users may change the radio’s over‐the‐air data rate and conducted output power using the speed and power commands. Keep in mind that the lower data rates offer higher receiver sensitivity and higher allowable conducted RF power in the ISM band. The following table shows the relation between speed settings, modulation scheme, receiver sensitivity, and allowable maximum power settings for each frequency band. The lowest power setting for all bands is –10 dBm. ‐ US / IC MODELS* Speed Modulation Receiver Max Power Max Power Max Power Setting Scheme Sensitivity 5.18 to 5.24 GHz 5.265‐ 5.325, 5.5 to 5.7 GHz 5.735 to 5.84 (over‐the‐air (dB) (dBm) (DFS‐UNII) (dBm) GHz (ISM) (dBm) rate) (Mbps) ...
Trango Systems, Inc TL45 User Manual Rev 2.0r3 In this example the user sets the power to 19dBm and the speed to 24 Mbps: #> power 19 Execution in progress... 19 dBm (-4..19) Success. #> speed 24 24 Mbps Success. #> MU Autoscan Feature Description This feature allows the RU to actively search all channels and polarizations for its peer MU in the event of a disassociation. This feature is useful if the user frequently changes the channel/polarization of the MU . If enabled, the autoscanmu routine in the RU performs a search for the peer MU by actively scanning all available channels and polarizations. NOTE: Autoscanning is always active when operating on DFS channels. Notes regarding the autoscanmu feature: The RU will not activate the autoscan process after first 60 seconds of turning on opmode. The RU will start the auto scan process If RU loses association for more than 10 seconds,. The whole process will scan ALL (DFS and non DFS) available frequencies and polarizations in channel tables. For each frequency, radio will survey both polarizations, H and V. It will record the following information: ‐ Association ‐...
Trango Systems, Inc TL45 User Manual Rev 2.0r3 Automatic Rate Shifting Feature Description With autorateshift feature enabled, the radios will automatically renegotiate the modulation method and speed speed to maximize wireless link integrity. The link speed will vary depending on two factors: 1) the number of ARQ errors received, 2) successful processing of special link assessment packets sent in both the current and next higher speed. The radio will shift to the next higher in speed when no errors are detected. The radio will shift down in speed if error rate is excessive. Notes regarding the autorateshift feature: 1. The radio will begin initial speed test when upon association to peer radio. There are 40 steps and around 50 seconds to complete this initial test. The radio will send link assessment packets (3600 byte packets at a rate of 100 packets per second) at the highest speed (54 Mbps). The radio will deliver payload at the speed which is specified before association. If the assessment packet dropping rate is higher than 10 percent, the speed test will decrease the speed for assessment packets. If the current payload speed is higher than the speed of assessment packet, the radio will set the current payload speed to be the same as the assessment packet’s speed. If the current payload speed is lower than the assessment packet’s speed and more than 500 assessment packets have been transmitted, the radio will set the payload speed to be the same as assessment packet’s speed. 2. After completion of initial speed test, the radio will set the payload speed to be the same as the final speed of initial speed test. 3. The radio will check link quality and adjust payload speed periodically. a. The radio will increase payload speed every 60 seconds, if i. Speed test which is running at higher speed is successful. –and‐ ii. Payload’s ARQ retransmit rate is less than 10 percent. b. Radio will decrease payload speed every 10 seconds, if i. Speed test which is running at payload speed is failure. –and‐ ii. ...
Trango Systems, Inc TL45 User Manual Rev 2.0r3 Encryption Feature Description The TrangoLINK‐45 system offers 128 bit proprietary encryption which may be turned on or off by the user. The HEX encryption key must be set in both the MU and RU. Users can expect faster payload speeds with encryption turned off as compared to with encryption turned on. Example: #> encrypt on Success. #> encrypt key 1111 2222 3333 4444 5555 6666 7777 8888 argc = 10 Success. #> MIR Feature Description Maximum Information rate is configurable on both the MU and RU. The MIR function is performed on the transmit side only and is based on a one second timing interval. During each one second timing interval, the total bits transferred is compared to the MIR limit configured by the user. When the limit is exceeded, no more data is sent and the packets in the queue will be dropped. This function is useful for reserving more bandwidth in one direction than the other. If left wide open, the system will respond to bandwidth demand as needed, allowing the full bandwidth of the channel to be used by either direction. Example: #>...

Trango Systems, Inc TL45 User Manual Rev 2.0r3 Chapter 4 Deployment & Installation Once you are familiar with the basic operation of the radios you are ready for deployment in the field. The deployment process consists of the following steps: Site Selection Site survey at MU and RU sites MU installation RU installation and antenna alignment Link test Site Selection Proper site selection for your MU will help ensure a successful deployment. Site selection will depend on a wide variety of factors, but from the radio’s performance standpoint, please consider the following: Path from MU to RU should provide unobstructed line‐of‐sight (LOS), thus it is advisable to place MU as high as • possible on a tall building or tower. Ethernet cable limit is 100 meters from Ethernet device (router, switch) to radio. • Radios should never be deployed without proper grounding. • Consider nearby sources of interference that could degrade the performance of the radio. Mount radios as far from • sources of interference as possible. Site survey ...
Trango Systems, Inc TL45 User Manual Rev 2.0r3 RSSI Command and Antenna Alignment Once the site survey is completed, you are ready to install your radios. Typically it is best to install the MU first. To properly align the radios, use the built‐in RSSI tool to achieve maximum signal strength. 1. Ensure MU and RU are in Opmode “ON.” 2. Connect to the RU. 3. L ogin and type the command rssi. As you read the RSSI, move the antenna in the horizontal and vertical planes until the maximum RSSI reading is achieved 4. I f it is not possible to receive an adequate RSSI reading, it may be necessary to reorient the MU (up/down, left/right), to increase the output power of the MU, or to move the RU to a location with better line‐of‐sight conditions to the MU. 5. O nce you are satisfied with the RSSI reading, tighten down the RU in the optimum position. Example: #> rssi Press any key to stop. 0> MU -75 dB -75 dB Connected...
