Abstract

A distributed antenna system includes at least one master unit communicatively coupled to at least one base station and a plurality of remote units located remotely from the at least one master unit. The plurality of remote units are communicatively coupled to the master unit over at least one transport communication link. The system is configured to distribute uplink and downlink signals between a base station and mobile units. A digital unit generates digital samples indicative of spectrum included in at least one of the uplink and downlink signals. A network interface communicates with an external computer. The digital unit is configured to process the digital samples and communicate information indicative of the spectrum to the external computer via the network interface.

First claim

What is claimed is:

1 . A distributed antenna system comprising:
at least one master unit communicatively coupled to at least one base station; and a plurality of remote units located remotely from the at least one master unit, wherein each of the plurality of remote units is communicatively coupled to the master unit over at least one transport communication link; the system configured to distribute a first signal, received from the at least one base station, from the master unit to at least one remote unit in analog form, wherein the at least one remote unit radiates a second signal derived from the first signal from at least one antenna associated with the at least one remote unit;
a digital unit to generate digital samples indicative of spectrum included in the first signal;
a network interface for communicating with an external computer; the digital unit configured to process the digital samples and communicate information indicative of the spectrum to the external computer via the network interface.

2 . The system of claim 1 , wherein the digital unit is configured to generate digital samples indicative of multiple frequency bands included in the first signal, and the digital unit being configured to process the digital samples and communicate information indicative of the multiple frequency bands to the external computer via the network interface.

3 . The system of claim 1 , wherein the digital unit is configured to process the digital samples and determine modulation information regarding the first signal, and further configured to communicate the modulation information to the external computer via the network interface.

4 . The system of claim 1 , wherein the digital unit is configured to process the digital samples and determine clocking information regarding the first signal, and further configured to communicate the clocking information to the external computer via the network interface.

5 . The system of claim 2 , wherein the digital unit is configured to evaluate the digital samples and to select a particular frequency band from the multiple frequency bands included in the first signal, and the digital unit being configured to process the digital samples of the particular frequency band separately from the digital signals of other of the multiple frequency bands.

6 . The system of claim 1 , wherein the digital unit is configured to process the digital samples and determine signal strength information regarding the first signal including, and further configured to communicate the signal strength information to the external computer via the network interface.

7 . The system of claim 1 , wherein the digital unit is configured to process the digital samples and determine propagation time information regarding the first signal including, and further configured to communicate the propagation time information to the external computer via the network interface.

8 . The system of claim 1 , wherein the transport communication link is a wireless link.

9 . The system of claim 1 , the digital unit configured to receive control data associated with the first signal via the network interface.

10 . A distributed antenna system comprising:
at least one master unit communicatively coupled to at least one base station; and a plurality of remote units located remotely from the at least one master unit, wherein each of the plurality of remote units is communicatively coupled to the master unit over at least one transport communication link; the system configured to distribute a first signal, received from at least one mobile unit, from at least one remote unit to the at least one master unit in analog form, wherein the at least one master unit forwards a second signal derived from the first signal to the at least one base station;
a digital unit to generate digital samples indicative of spectrum included in the first signal;
a network interface for communicating with an external computer; the digital unit configured to process the digital samples and communicate information indicative of the spectrum to the external computer via the network interface.

11 . The system of claim 10 , wherein the digital unit is configured to generate digital samples indicative of multiple frequency bands included in the first signal, wherein digital unit is configured to process the digital samples and communicate information indicative of the multiple frequency bands to the external computer via the network interface.

12 . The system of claim 10 , wherein the digital unit is configured to process the digital samples and determine modulation information regarding the first signal, and further configured to communicate the modulation information to the external computer via the network interface.

13 . The system of claim 10 , wherein the digital unit is configured to process the digital samples and determine clocking information regarding the first signal, and further configured to communicate the clocking information to the external computer via the network interface.

14 . The system of claim 11 , wherein the digital unit is configured to evaluate the digital samples and to select a particular frequency band from the multiple frequency bands included in the first signal, and the digital unit being configured to process the digital samples of the particular frequency band separately from the digital signals of other of the multiple frequency bands.

15 . The system of claim 10 , wherein the digital unit is configured to process the digital samples and determine signal strength information regarding the first signal including, and further configured to communicate the signal strength information to the external computer via the network interface.

16 . The system of claim 10 , wherein the digital unit is configured to process the digital samples and determine propagation time information regarding the first signal including, and further configured to communicate the propagation time information to the external computer via the network interface.

17 . The system of claim 10 , wherein the transport communication link is a wireless link.

18 . The system of claim 10 , the digital unit configured to receive control data associated with the first signal via the network interface.
