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.
