Patent ID: 8588614

Claim:
An apparatus comprising: a radio frequency (RF) conditioning module having a plurality of first physical interfaces and being configured to: receive respective input digital RF physical signals via at least two of the plurality of first physical interfaces, wherein the respective input digital RF physical signals include a plurality of RF base transceiver station (BTS) signals, split each received respective input digital RF physical signal into a respective number of duplicate signals, combine particular duplicate signals selected from among each of the respective number of duplicate signals into one or more superposition RF signals, and route and transmit the one or more superposition RF signals to an array of remote antenna nodes to which the apparatus is configured to be communicatively coupled; and one or more low-power RF modules each having a communicative connection to a respective one of the plurality of first physical interfaces, and each configured to: receive respective baseband digital optical signals via a respective second physical interface, wherein the respective baseband digital optical signals include a plurality of baseband signals in a baseband frequency range, modulate the received respective baseband digital optical signal to a respective RF passband signal, and send the respective RF passband signal to the RF conditioning module via the communicative connection to the one of the plurality of first physical interfaces as one of the respective input digital RF physical signals.
