Abstract

We suggest the use of dynamic channel allocation for reverse paging in the ISM (Industrial Scientific and Medical) band. A method of dynami- cally allocating spread spectrum channels to a population of pagers within a given coverage zone is described. An accurate profile of the ISM band at the subject spread spectrum receiver location should be drawn and continuously updated. Band profile estimation are based on the radiometer shown in Figure 1. This energy detector consists of a bandpass filter (BPF) of center frequency f, and bandwidth W and a square law operation followed by a T-second integrator. The integrator is reset at the end of each successive T-second period. T is generally dictated by the dynamics of the ISM band. If the profile changes every T, second then the appropriate value of T would be T..
