G-7 REUSE PLAN
A reuse plan allows nets to reuse (share) frequencies (VHF-FM band only) with
Nets which operate low power radios with short range
communications requirements are the nucleus of a frequency reuse plan.
with long geographic separation or terrain masking are also considered for
This concept is best described by example. Suppose that
there are three regions (zones) that are geographically separated from each
other and each region contains three nets as shown in Table G-1.
If the nets in a zone can not interfere with nets in another zone, then only
three frequencies are required to satisfy the nine nets. A net in the three
zones can use the same frequency for one time period without causing problems.
In the SOI generation process, the three nets in each zone are randomly
assigned the same three frequencies.
For example, in time period 1, net A1, B1 and C1 may share the same frequency
while net A2, B2 and C2 share a frequency and nets A3, B3 and C3 share a
In time period No. 2, nets A1, B2 and C3 may share a frequency.
Nets A2, B1 and C1 may share the same frequency and nets A3, B3 and C2 may
share the same frequency.
In summary, the nets in Zones B and C can reuse the frequencies used in Zone A
the nets are geographically separated and can not interfere with each
