Abstract

A local-area RF communication unit (305) is incorporated in a portable housing, such as a briefcase (101), and adapted to communicate with personal communication devices, such as a handset (105) and notepad (107). One or more wide-area RF communication units (303) are disposed in the briefcase (101) and adapted to communicate with a wide-area communication system. The local-area RF communication unit (305) and the wide-area communication unit are selectively controlled by a microprocessor (301) within the briefcase (101).
