Abstract
An integrated radio frequency communication system, known as a Location-Ruled Radio-Integrated Network (LORRAINE) system, provides integrated voice, data and location services. The radio frequency communications system combines time division multiplexing (TDM) techniques with optional time division duplexing (TDD) or frequency division duplexing (FDD) techniques to provide a plurality of time slot channels for these services. Spread spectrum techniques help reduce noise and interference in the system.
