A simulation model for characterizing the geometry of infrared communication cells representing full connectivity has been developed. Measured spatial daylight distributions in a large open-plan office have been incorporated into the model. With a 1 Mbps transmission system based on 16-slot pulse-position modulation and a non-directed infrared source of 250 mW average optical power, cell sizes of up to 10 m and 20 m diameter can be achieved for peer-to-peer and client/server topologies, respectively. Daylight variations cause severe distortions and size reductions of the cells. A transmission system with adaptive data rate control (10 kbps to 10 Mbps) maintains full network connectivity within the cells at the expense of a graceful throughput degradation for terminals exposed to high levels of ambient light. |
