Abstract

A portable transceiver for indoor wireless link that employs a transmitter of eye-safe infrared light-emitting diodes and a receiver of photodiode arrays with multichannel transimpedance-summer architecture is presented. The transmitter can attain a wide field of view (up to 55 deg half-angle) and high speed (up to 35 MHz) to support different intensity modulation schemes. The receiver can receive signals with a bit error rate (BER) of 10^–4at a plane of 2 m away from the transmitter, even at a point ±50 deg off the transmitter's vertical axis. The bit rate of the transceiver can achieve up to 40 Mbit/s in an indoor nondirected infrared wireless link, and can be extended to 100 Mbit/s when light-emitting diodes (LEDs) with higher cut frequency are used. The system is able to transmit real-time uncompressed video 320×240 in frame size.
