Communication system with geographic reuse dynamically sensitive to communication unit type
First Claim
1. A frequency reuse method for use with a plurality of communication units, the plurality of communication units including at least a first type of communication unit and a second type of communication unit, wherein the first type of communication unit comprises a portable two-way radio, and the second type of communication unit comprises a land vehicle mounted two-way radio, the method comprising the steps of:
- A) providing a plurality of radio communication sites, wherein at least some of the radio communication sites have a plurality of frequencies potentially available for allocation to support communications amongst the communication units;
B) assigning, in one of the radio communication sites, at least a particular frequency to support communication needs of a particular communication unit;
C) adjusting availability of that particular frequency in other of the communication sites as a function, at least in part, of whether the particular communication unit is the first type of communication unit or the second type of communication unit.

Abstract
Geographic reuse of frequencies within a multisite communication system are dynamically altered as a function of communication unit type. Since some communication unit types pose a smaller risk of interference, increased geographic reuse can be tolerated. Similarly, reuse can be diminished to accommodate communication unit types that pose a significant risk of interference over a wide geographic area.
