15 C H A P T E R Connecting Wireless Multipoint Network Modules This chapter explains how to connect the wireless multipoint network module and contains the following sections: • Wireless Multipoint Network Modules, page 15-1 • Subscriber-Unit System, page 15-2 • Hardware and Software Requirements, page 15-3 • Connecting Wireless Ports to the Network, page 15-3 • Wireless Multipoint Network Module LEDs, page 15-3 • Related Documents, page 15-4 Tip To determine whether your router supports a specific network module, see Table 1-6 on page 1-16. Wireless Multipoint Network Modules The wireless multipoint network module, shown in Figure 15-1, also referred to as a subscriber unit (SU), provides a high-speed broadband fixed wireless radio-frequency (RF) link between each subscriber site and a single headend site. This link delivers full-duplex data in the licensed MMDS band (2.500 to 2.690 GHz) or unlicensed U-NII band (5.725 to 5.825 GHz). The headend of the system consists of a Cisco uBR7200 series universal broadband router, one or more wireless modem cards, and the required subsystem for each modem card. The diversity option, which minimizes the effects of fading, uses two wireless transverters at each site, with each transverter connected to its own antenna. (See Figure 15-2.)
