| Abstract: |
A mobile communication device is constructed for use in communicating with a wireless communications network. The device is adapted for carrying on or near the person of the user. For ease of use and adaptability, the various functions of the device are separated into multiple units. The units communicate with each other through a localized communication system in which at least one local traffic channel is generated by the primary unit. To permit bi-directional communication among the units, multiple access protocols are used, either TDMA or CDMA.

What is claimed is:
1. Apparatus for wireless communication with a mobile telephone network, the apparatus comprising:
- a primary unit, adapted for carrying on or near the person of the user, having means to communicate with the mobile telephone network over a network traffic channel, and having a first local wireless communication means constructed to generate a first local traffic channel using multiple access protocols selected from TDMA and individual frequency hopping or CDMA and individual pseudorandom binary sequence;
- a secondary unit, adapted for carrying on or near the person of the user, having a second local wireless communication means constructed to communicate over said first local traffic channel with said first local wireless communication means to bidirectionally transfer data between said primary unit and said secondary unit;
- wherein said local traffic channel accommodates communications in both directions utilizing the selected multiple access protocol, and wherein said secondary unit generates a second local traffic channel; and
- a third unit adapted for carrying on or near the person of the user, having a third local wireless communication means arranged to communicate over said second local traffic channel with said second local wireless communication means to bi-directionally transfer data between said secondary unit and said third unit.
