Communications using fibre optics and radio

摘要

A personal communications terminal is usable with signals in the radio and in the optical regions of the electromagnetic spectrum. The terminal has a 3-part modular structure comprising a front end module 1 provided with radio 7 and optical 6 communications interfaces; a processor/controller module 2 connected to the front end module and a user interface module 3 connected to the processor/controller module. Fibre optic communication is used where possible with radio available as an alternative (Figs 2a-2e). Typical, possibly hybrid deployment configurations are shown (Figs 3, 4).
