ABSTRACT:
A modular communication device (102), which provides for radio frequency (RF) communication in a communication system (100), comprises a first modular unit (106) and a second modular unit (108). The first modular unit (106) includes a housing (110); a user interface (113) including a display (114) and keys (116); electrical circuitry (605), including a transceiver (606) coupled to an antenna (610); a battery connection interface (308) for receiving a battery (302); and a connection interface (120). The second modular unit (108) includes a housing (128); a user interface (135) including a speaker (650), a microphone (648), and a keypad (140); a retractable antenna (134); a battery connection interface (402) for receiving a battery (142); and a connection interface (143). When the connection interfaces (143, 120) are connected, the user interface (135), the antenna (134), and the battery connection interface (402) are coupled to the electrical circuitry (602).
