Infrared has abundant, unregulated bandwidth enabling rapid deployment at low cost. However, safety limits on power emission levels (IEC825), large noise due to ambient lighting, and multipath dispersion remain as hurdles in diffused indoor environments. Especially, the high-frequency periodic interference produced by fluorescent lights is a major concern.(More)
IR is specified as an option for IEEE 802.11 wireless LAN standards because, the IR band has abundant, unregulated bandwidth, enabling rapid deployment at low cost. IR systems do not interfere (EMI) with RF systems. However, limitations over power emission levels (IEC825), noise due to ambient lighting and multipath dispersion remain as hurdles in(More)
