Base station with automatic cable loss compensation

摘要

The present invention relates to a TDD base station wherein at least one cable extends between first and second locations, the base station comprising: a first power level detection means 402 for determining transmit signal power level at said first location and a second power level detection means 403 at said second location; feed back means (350) for feeding back the transmit signal power level from said second location to said first location; comparing means (300) at the first location for comparing power levels from the first and second power level detection means and for determining a loss between the two locations; attenuating means 401, 404 at the first location for controlling the power level of the transmit signal; and, control means 311 at the first location responsive to the comparing means 311 for controlling the attenuating means.
