Abstract

A summing unit within telecommunications system includes: port to receive digital data stream from another device; and summer function. Digital data stream includes first and second digital data derived from first and second base station. First and second digital data comprises first and second digital values associated with respective time periods. Summing unit extracts first digital data from digital data stream. Summer function digitally sums first digital data with third digital data derived from third base station to generate summed digital data for conversion to radio frequency signals and transmission at antenna. Third digital data comprises third series of third digital values associated with respective time periods. Summer function digitally sums first digital data with third digital data by digitally summing (i) first digital value associated with respective time period and (ii) third digital value associated with respective time period to produce summed value for respective time period.

First claim

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.

2. The summing unit of claim 1 , further comprising:
at least a second port configured to receive the third digital data derived from the third base station via a second another device.

3. The summing unit of claim 1 , further comprising at least a second port configured to transmit the summed digital data to a remote antenna unit, wherein the remote antenna unit includes the antenna, the remote antenna unit configured to convert at least a portion of the summed digital data into the radio frequency signals within at least one radio frequency band, the remote antenna unit further configured to transmit the radio frequency signals within the at least one radio frequency band from the antenna of the remote antenna unit to at least one subscriber unit.

4. The summing unit of claim 1 , wherein the second digital data derived from the second base station is received from the second base station via a second another device.

5. The summing unit of claim 1 , wherein an Ethernet switch is positioned within a signal path between the first base station and the summing unit.

6. The summing unit of claim 1 , wherein the telecommunications system is a distributed antenna system.

7. The summing unit of claim 1 , wherein each of the first series of first digital values, the second series of second digital values, and the third series of third digital values include a baseband I/Q value having a respective in-phase (I) part and a respective quadrature (Q) part.

8. A method for communication within a telecommunications system, the method comprising:
receiving a digital data stream at a summing unit 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, 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;
