including hardware network management and administration.
Figure 3-2: VIDA Broadband Network
The basic architecture of the 4.9 GHz VIDA Broadband network is a point-to-multipoint network. A
system consists of one or more base station(s) and at least one or more clients per base station as shown in
Figure 3-2. There are two configurations of client devices; fixed and nomadic. Fixed client devices are
usually mounted outdoors with directional antennas and have a range of up to 10 miles. Nomadic clients
are vehicle mounted and use an omnidirectional antenna. The range of a nomadic client to base station is
typically a few hundred meters.
The VIDA Broadband Base Station implements the 802.16e-2005 OFDM protocol to deliver an over-the-
air throughput from 3 to 19 Mbps (for 5 MHz channel) and 3 to 38 Mbps (for 10 MHz channel). All
communication over the wireless channel is scheduled by the base station, with contention slots provided
