Abstract

A radiotelephone arrangement uses optical coupling between two discrete elements, specifically a handportable telephone (1) and a car fitting stand (2) or between a mobile handset and a radio unit. This coupling is resistant to continuous vibration, humidity and pollution. Also, the arrangement significantly reduces interference radiated from the telephone housing. A charging device (12) included in the fitting stand (2) may be coupled electrically to a battery 9 of the handportable telephone (1) and the charging device may be actuated by an optical signal (17) from the telephone. The optical coupling (13-17) may take place through free space or an optical cable. <IMAGE>
