Multipoint Headend System
The Cisco broadband fixed wireless multipoint headend system is designed to use antennas that transmit
the RF signal in a portion of a complete circle, or directionally, in what is called a sector. Each headend
site can be designed and configured to broadcast in a single sector, or in multiple sectors, depending on
the requirements of the network.
For each sector, the components of a multipoint headend system (see Figure 1) consist of the necessary
cables and:
• One Cisco uBR7200 series universal broadband router
• One wireless modem card installed in the router
• One power feed panel
• One or two antennas (second antenna for diversity reception is optional)
• One or two wireless transverters containing the RF amplifier (one for each antenna)
• One or two duplexers (one for each wireless transverter)
