An indoor base transceiver system (BTS) provides economical coverage by having a network-coupled base station that monitors a plurality of remote transceiver units (RTUs), or RF nodes, communicating by base-band conduits at symbol data rate. The BTS can reduce cost by interconnecting coverage nodes at the bit rate and can reduce cost by interconnecting coverage nodes at the symbol rate. The BTS can implement the modulation/demodulation function in a split fashion, with part of this accomplished in the RF Node and part accomplished in an Aggregator of the base station. System capacity can be retained by using selection combining and by using maximal ratio combining. Multiple carriers can be supported by messaging on the signal link and performing the frequency selection/generation at the remote Node. Deployment can be simplified by allowing coverage overlap of Nodes. |
