Abstract :
An IR/RF wireless transmission system is described with emphasis placed on a PSK circuit common to all output sections. The system is capable of achieving communication in relatively small rooms with infra-red (IR) radiation, in large rooms and corridors with RF transmission (125 MHz) and outside communication with higher RF frequencies (668 MHz).
