FHSS optical wireless transceiver for short range low-speed indoor sensor interconnection

Abstract

Experimental and simulation results from the operation of a prototype of wireless indoor optical transceiver based on frequency hopping techniques are presented. We choose spread spectrum techniques, as it allows multiple simultaneous accesses and also increases the robustness of the system against multipath‐induced distortion. It also reduces the effect of narrowband interference, as could be low‐frequency optical noise from fluorescence or incandescence lamps. FHSS techniques also allow coexistence with IrDA or remote control emitting devices without causing of suffering interferences.
