Abstract:
A method of distributing multiband radio frequency (RF) signals in a wireless communications system, comprising:a) receiving at a main unit a plurality of downlink RF-sets in a plurality of downlink frequency bands, wherein each of said downlink RF-sets contains downlink RF signals in one of said downlink frequency bands; b) combining said downlink RF-sets into a multiband combined downlink RF signal; c) splitting said multiband combined downlink RF signal into multiple multiband downlink RF-parts; d) converting said multiple multiband downlink RF-parts to multiple downlink optical signals; e) optically transmitting said downlink optical signals to multiple remote units; f) receiving a delivered downlink optical signal at each of said remote units; g) converting said delivered downlink optical signal to a multiband delivered downlink RF-part; h) separating said multiband delivered downlink RF-part into a plurality of downlink RF-groups by frequency band; i) performing individual downlink-signal-conditioning on each of said downlink RF-groups, including one or more steps of RF-amplifying, gain-adjusting, and RF-filtering; j) combining said individual-conditioned downlink RF groups into a multiband downlink RF transmit signal; and k) transmitting said multiband downlink RF transmit signal to at least one dedicated downlink antenna; wherein said at least one dedicated downlink antenna is not used for uplink reception.
