4. CHANNEL SELECTION
The FCC has allocated 83.5 MHz of spectrum in the 2.4 GHz band where the TRACER 4106 operates, and
125 MHz of spectrum in the 5.8 GHz band where the TRACER 4206 operates. Figure 1 and Figure 2
illustrate the bandwidth division.
Figure 1. 2.4 GHz Bandwidth Division (TRACER 4106)
Figure 2. 5.8 GHz Bandwidth Division (TRACER 4206)
To designate the utilization of the ISM bandwidth, there are two different channel plans, labeled A and B.
The letter of each channel plan setting is preset by the factory and refers to the physical configuration of
the diplexer filter inside the environmental housing. Each channel is then divided into three bandplans (1, 2
or 3). The bandplans must be the same for the local and remote TRACER 4106/4206. For example, the
transmitter at one end of the link will transmit in bandplan 1 of channel A (the lower portion of the
spectrum) and receive in bandplan 1 of channel B (the upper portion). Consequently, the receiver at the
other end should receive in bandplan 1 of channel A (the lower portion) and transmit in bandplan 1 of
channel B (the upper portion).
