  • Page 6: About Tsunami Multipoint

    Tsunami Multipoint Version 2.0 Reference Manual About Tsunami Multipoint Tsunami Multipoint is a point-to-multipoint outdoor wireless system offering a high capacity alternative to wired data networks. Using IP packet radio transmitters, standard Ethernet interfaces, and an easy-to-deploy design, the Tsunami Multipoint system enables high-speed network connections to multiple Ethernet switches, routers or PCs from a single location.

  • Page 7: Chapter 1. System Overview

    Tsunami Multipoint Version 2.0 Reference Manual Chapter 1. System Overview A Tsunami Multipoint system is comprised of one-to-six Base Station Units (BSUs) and associated Subscriber Units (SUs) that comprise a cell. Each BSU communicates with its associated SUs in its sector.

  • Page 8: Table 1 Maximum Burst Rates

    Tsunami Multipoint Version 2.0 Reference Manual A single cell of six 60-degree sectors can communicate in all directions (360°). Each sector, consisting of a single BSU and associated SUs (a single BSU can communicate with up to 1,023 SUs ), can be configured to communicate at a maximum burst rate of 60 Mbps.

  • Page 9: Figure 2. Single Frame

    Tsunami Multipoint Version 2.0 Reference Manual ..Figure 2. Single Frame The BSU determines which SU is to transmit at what instant in time. The entire frame consists of a fixed number of slots (the exact number depends upon the data rate used (such as 30 Mbps, 40 Mbps, or 60 Mbps).

  • Page 11 Tsunami Multipoint Version 2.0 Reference Manual The advantages of the Optional Mode are: Longer maximum range The maximum range (maximum distance between a BSU and SU) is determined by a number of factors including modulation type, transmit power, antenna gain, required fade margin, and length of guard interval.

  • Page 12: Table 6 Center Channel Frequencies

    Tsunami Multipoint Version 2.0 Reference Manual Frequency Band The Tsunami Multipoint operates in the 5.725 to 5.825 Unlicensed Frequency band. Within this band, you can select one of three channel plans: 4, 5, or 6. The following table contains the center frequencies for all of the channels in each of these plans.
  • Page 13 Tsunami Multipoint Version 2.0 Reference Manual Ranging and Power Adjustment Tsunami Multipoint uses Time Division Multiple Access (TDMA) on the uplink to let multiple users use the single uplink. In TDMA different SUs are assigned different time sub-slots to transmit their signals.
  • Page 14 Tsunami Multipoint Version 2.0 Reference Manual Note: Waiting ten minutes before searching other frequencies was chosen for the following reason: A BSU using GPS to synchronize its timing can take close to 10 minutes to resume transmission after a power cycle. Much of this time is required for the GPS receiver to acquire the four satellites required to obtain accurate timing information.

  • Page 15: Packet Routing Modes: Ip Routing And Bridging

    In Bridging mode, the Tsunami Multipoint network uses the ARP table to filter packets; each SU can capture and store up to 8,000 local addresses in its ARP table. Proxim recommends using Bridging mode as it is the most “plug-and-play” mode and requires little network configuration.

  • Page 16: Wireline Interface

    Tsunami Multipoint Version 2.0 Reference Manual ▪ Similarly, any downlink packet received by the SU is filtered through the ARP table before being transmitted to its local network. If the destination address of the received packet cannot be found in the ARP table, the packet is dropped.

  • Page 17: Voip Support

    Tsunami Multipoint Version 2.0 Reference Manual Symptoms of mismatch problems include: ▪ Network performance that is considerably lower than it should be ▪ Significant errors shown when using the netstat –e command To alleviate this problem, you can disable the auto-negotiate feature of the BSU/SU and use the setEthernet command for the BSU and the setSUEthernet command (entered at the BSU to set the SU Ethernet interface) to manually set the Ethernet interface to the desired mode.

  • Page 18: Chapter 2. Ethernet (Mac) Bridging Mode

    Tsunami Multipoint Version 2.0 Reference Manual Chapter 2. Ethernet (MAC) Bridging Mode In Ethernet Bridging mode, the PMP network provides a direct physical connection between an SU and its BSU for the exchange of Ethernet frames between the two units. To conserve wireless bandwidth, the SU uses some simple hardware and software filtering criteria to prevent traffic destined for a local network from being sent uplink.

  • Page 19: Static Entries

    Tsunami Multipoint Version 2.0 Reference Manual ▪ If the MAC filtering mode is set to on: º Packets addressed to a broadcast Ethernet address are passed onto the local network. º For other packets, the SU determines whether the downlink packet’s destination Ethernet address triggers a “hit”...

  • Page 20: Vlan Switching - The Pmp Implementation

    Tsunami Multipoint Version 2.0 Reference Manual VLAN SWITCHING – THE PMP IMPLEMENTATION VLAN switching is used primarily for segregating LAN traffic based upon a VLAN ID that accompanies a received VLAN frame. VLAN switching is useful because: ▪ It lets network operators partition their LAN segment into closed user groups.
  • Page 21 Tsunami Multipoint Version 2.0 Reference Manual Note: The VLAN IDs of all BSUs default to VLAN ID 1. You can use the setVLAN command to set the BSU VLAN ID to a value between 1 and 4094, inclusive. See “setVLAN” on page 93.

    Tsunami Multipoint Version 2.0 Reference Manual VLAN Filter Policy Summary The following figure illustrates the concept of setting up multiple VLAN IDs at an individual SU. The X axis indicates the VLAN filter policies (1 ~ 16) and the Y axis indicates the available VLAN ID space (1 ~ 4095).
  • Page 25 Tsunami Multipoint Version 2.0 Reference Manual Be aware of the following: ▪ The value of any VLAN ID should be from 1 to 4095. ▪ The start VLAN ID cannot be greater than the end VLAN ID. ▪ If the end VLAN ID is not indicated, the firmware sets the end VLAN ID to the same value as the start VLAN ID.

  • Page 26: Chapter 3. Ip Routing Mode

    Tsunami Multipoint Version 2.0 Reference Manual Chapter 3. IP Routing Mode In contrast to Bridging mode, in which packets are delivered based upon their Ethernet addresses, IP Routing mode routes packets based upon their IP addresses. IP Routing makes more efficient use of the wireless link as the BSU and SU terminate broadcast messages and do not send them over the wireless link.

  • Page 27: Arp Tables

    Tsunami Multipoint Version 2.0 Reference Manual Note: Make sure that every BSU is on a different subnet while in IP Routing mode (see the routingMode command on page 89 for information about selecting the routing mode). If the BSUs are on the same subnet, the BSUs cannot respond properly to ARP requests.

  • Page 28: Access Modes

    Tsunami Multipoint Version 2.0 Reference Manual ACCESS MODES In IP routing mode, you can select one-of-two access modes for each SU—restricted or open. You select the desired mode using the setSUFilter command (page 100). Note: Each SU can be set to a different access mode.

  • Page 29: Wireless Link Packets Destined For Local Subnet Ip Addresses

    Tsunami Multipoint Version 2.0 Reference Manual Open Mode In open mode, the SU passes traffic to the SU wireline for any host whose IP address is in the same subnet as the SU. If RIP is disabled and a default gateway is defined, the SU passes all downlink traffic not in the SU ARP table to the default gateway (this includes traffic in the same subnet as the SU that is not in the SU ARP table).

  • Page 30: Ip Routing Deployment With Rip Disabled

    Tsunami Multipoint Version 2.0 Reference Manual IP ROUTING DEPLOYMENT WITH RIP DISABLED Firmware versions prior to Version 1.3 did not have routing features enabled. A combination of default gateways and proxy were used to deploy networks in IP routing mode in these versions of the firmware. It is still possible to deploy networks in this manner by disabling RIP and enabling proxy.
  • Page 31 Tsunami Multipoint Version 2.0 Reference Manual Note: The BSU must only proxy for hosts on the SU side of the subnet and not for hosts on the BSU side of the network (and vice versa). If, for example, communication is lost with a particular host on the BSU local network and another device on the local network ARP is looking for the unavailable host, the BSU proxies for the unavailable host.

  • Page 32: Figure 10. Network Diagram Example 1 Configuration Settings

    Tsunami Multipoint Version 2.0 Reference Manual ▪ Router1 sends packet to BSU2 by way of the other router port (the one associated with IP address 192.68.21.1). ▪ PC3 ultimately receives the packet by following a process similar to the one described above.

  • Page 33: Packet Routing And Rip

    Tsunami Multipoint Version 2.0 Reference Manual PACKET ROUTING AND RIP Tsunami Multipoint’s IP routing capabilities are geared for a small campus environment in which a single company’s IT infrastructure is distributed between different buildings. In the router environment, route information must be distributed to all users dynamically. An example network topology is provided in Figure 11.

  • Page 34: Figure 12. Sector Acting As A Virtual Router In Ip Routing Mode

    Tsunami Multipoint Version 2.0 Reference Manual With Routing Information Protocol Version 2 (RIP V2) enabled, the combination of BSU and associated SUs act as a (virtual) multi-port router. The BSU and each SU act as different ports (interfaces) on the router.
  • Page 35 SU-to-SU loopback, and at the SU that is connected to the Internet (to allow the Internet traffic to pass). Note: Proxim strongly urges that default gateways be defined only at the BSU and, at most, a single SU. The software allows a default gateway to be assigned to each SU; however, assigning default gateways to multiple SUs can lead to duplicate packets being dumped onto the different wireline networks.
  • Page 36 Tsunami Multipoint Version 2.0 Reference Manual Example 2 — Network Deployment with RIP Enabled In this more complicated example, the SUs and BSUs are assigned to different networks. This is possible because, in IP Routing mode, the PMP network can function as a multi-port router, where each port has its own network address.
