1. A summing unit within a telecommunications system, the summing unit comprising:
at least one port configured to receive a digital data stream from another device, the digital data stream including first digital data derived from a first base station and second digital data derived from a second base station, wherein the first digital data comprises a first series of first digital values, wherein each respective first digital value of the first series of first digital values is associated with a respective time period, and wherein the second digital data comprises a second series of second digital values, wherein each respective second digital value of the second series of second digital values is associated with the respective time period;
wherein the summing unit is configured to extract the first digital data from the digital data stream;
at least one summer function configured to digitally sum the first digital data with third digital data derived from a third base station to generate summed digital data for conversion to radio frequency signals and transmission at an antenna, wherein the third digital data comprises a third series of third digital values, wherein each respective third digital value of the third series of third digital values is associated with the respective time period;
wherein the at least one summer function is configured to digitally sum the first digital data with the third digital data by, for each respective time period, digitally summing (i) the respective first digital value associated with the respective time period and (ii) the respective third digital value associated with the respective time period, thereby producing a respective summed value for the respective time period comprising a respective single value that is a function of a respective mathematical summing operation performed using, as inputs thereto, the respective first digital value associated with the respective time period and the respective third digital value associated with the respective time period.
