Abstract
A distributed antenna system comprises: a plurality of ports configured to receive downstream signals or transmit upstream signals; a plurality of first antennas configured to transmit the downstream signals or receive the upstream signals; a power regulating unit coupled between the plurality of ports and the plurality of first antennas and configured to transfer and regulate the downstream signals or the upstream signals, wherein the power regulating unit comprises: a plurality of first links respectively corresponding to different frequency bands, and a first power regulating section configured to regulate power of link signals transferred over each first link, such that link signals of different frequency bands transferred over the plurality of first links have substantially the same power. The solution of the present disclosure can support input of signals at multiple frequency bands, achieve power balance and improve system performance and wireless coverage effects.
