Point-to-Multipoint Backhaul
5.1 Overview
A channel is a frequency band of a specified width. For example, if the center frequency
is 2.412 GHz, and the frequency band is 80 MHz wide, there are 40 MHz on either side
of the center frequency, and the frequency range for that channel is 2.372 to 2.452 GHz.
Some custom configurations will require multiple channels operating at the same time.
Verify that channel ranges do not overlap to avoid interference.
The recording truck radios are configured Access Points (A) and the line station radios
are configured as Stations (S).
An Access Point communicates only with a Station. An Access Point cannot communicate
with an Access Point, and a Station cannot communicate with a Station.

NOTE
A line station mast requires an LIU to communicate with the recording truck. A
mast located at the recording truck can communicate using an LIU or a PoE
connected directly to the recording truck computer. See the following figures for
examples.
