1. A wireless communication system comprising:
- a base network control means for receiving calls from and forwarding calls to an external communications network, and for generating a frequency hopping signal;
a plurality of portable radio sets each having a frequency hopping transmitter and a frequency hopping receiver; and
a plurality of fixed radio ports mounted at spaced locations to define a plurality of cells, each said port connected to said base network control means, and each said port including a digital transceiver means for transmitting and receiving frequency hopping radio signals for communicating with said portable sets and wherein said frequency hopping signal for each hop includes a first set of adjacent data receiving slots, a second set of adjacent data transmitting slots and a midamble slot placed between said first and second set of slots.

Abstract
A digital voice-data communication system having a base network control unit coupled to a plurality of fixed transceivers for providing communications to a plurality of portable sets. The base network control unit includes control means for permitting communication between the portable sets within the system, or between the portable sets and a larger external telecommunications network. The system employs frequency hopping, time division multiplexing and demand assigned multiple accessing to permit economy of fixed resources via multiple voice channels for each fixed station transceiver and relatively simple portable sets which may be hand held.
