Patent ID: 7215888

Claim:
A method of varying loop gain in an optical wireless link, the method comprising the steps of: calibrating the optical wireless link to generate a default loop gain, KnomDist, for a first operating distance between a transmitting station and a receiving station; determining a real operating distance between the transmitting station and the receiving station; and calibrating the optical wireless link to generate an optimized loop gain, Kdist, as a function of the default loop gain, the first operating distance, and the real operating distance wherein the optimized loop gain, Kdist, is generated according to the relationship Kdist=KNomDist*NomDist/Distance, where KnomDist is the default loop gain for the first operating distance between the transmitting station and the receiving station, NomDist is the first operating distance between the transmitting station and the receiving station, and Distance is the real operating distance between the transmitting station and the receiving station.
