Abstract:
1. A distributed base station radio system comprising: a first channelized to broadband conversion unit configured to receive first downlink digital channelized data for a first radio frequency band from a first channelized radio frequency source, wherein the first downlink digital channelized data is specific to a first channel; wherein the first channelized to broadband conversion unit is further configured to convert the first downlink digital channelized data into a first downlink digital broadband signal having a single center frequency, wherein the first downlink digital broadband signal is configured to represent a portion of radio frequency spectrum having a plurality of channels, the plurality of channels including the first channel, wherein each of the plurality of channels is configured to be in non-overlapping locations within the first downlink digital broadband signal that reflect the location of each channel within the portion of radio frequency spectrum relative to the plurality of channels; a first universal remote radio head communicatively coupled to the first channelized to broadband conversion unit; wherein the first channelized to broadband conversion unit is further configured to communicate the first downlink digital broadband signal to the first universal remote radio head; wherein the first universal remote radio head is configured to receive the first downlink digital broadband signal; wherein the first universal remote radio head is further configured to convert the first downlink digital broadband signal into first downlink analog radio frequency signals in the first radio frequency band through at least one of frequency conversion and digital to analog conversion; wherein the first universal remote radio head is further configured to transmit the first downlink analog radio frequency signals in the first radio frequency band to a first subscriber unit.
