Question: Digital Radio: Consider a digital radio link between a laptop computer and a network base station in the same building. The maximum distance is 100 m, and the link losses are no more than 20 dB. The link must carry a 10-Mb/s (ethemet rate) signal with a BER of I 0-22 or better. The antennae are both non-directional (unity gain). How much transmitter output power is required for the link?
