Abstract

Systems and methods for optimized telecommunications distribution are provided. For example, a distributed antenna system can include a master unit for transceiving signals with remote units operable for wirelessly transceiving signals with mobile devices in a coverage area. A self-optimized network analyzer can be in a unit of the distributed antenna system. A self-optimized network controller in the distributed antenna system can output commands for changing operation of a component in the distributed antenna system in response to analysis results from the self-optimized network analyzer. In some aspects, the master unit includes base transceiver station cards for receiving call information in network protocol data from a network and for generating digital signals including the call information from the network protocol data for distribution to the remote units.

Claims

1. A system comprising:

a plurality of remote units of a distributed antenna system, each of the plurality of remote units including a circuit, the plurality of remote units configured to wirelessly receive uplink signals from mobile devices in a coverage area; and

a unit including a circuit, the unit communicatively connectable to the plurality of remote units, the unit being configured for;

instructing a remote unit of the plurality of remote units to wirelessly receive signals in a downlink band; and

sending a command to the remote unit regarding transmission of downlink signals in the downlink band based on an analysis of the received signals by a self-optimized network analyzer in a unit of the distributed antenna system; and

a self-optimized network controller adapted for selecting channels for use in the distributed antenna system based on database information and signals from a macro-cell environment processed by the self-optimized network analyzer, wherein the database information used for selecting the channels includes a location of the system.

2. The system of claim 1, wherein the unit is configured for instructing the remote unit to receive the signals in the downlink band by sending a command to the remote unit to use a receiver to receive the signals, wherein the receiver comprises a dedicated receiver configured for monitoring downlink bands and the remote unit comprises an additional receiver configured for monitoring uplink bands.

3. The system of claim 1, wherein the unit is configured for instructing the remote unit to receive the signals in the downlink band by sending a command to the remote unit to tune a receiver from an uplink band to the downlink band.

4. The system of claim 1, wherein the self-optimized network analyzer is in at least one remote unit of the plurality of remote units.

5. The system of claim 1, wherein the unit comprises a master unit of the distributed antenna system configured for communicating the downlink signals from a base station to the plurality of remote units.

6. The system of claim 1, wherein the unit is further configured for:

receiving call information in network protocol data from a network,

decoding the network protocol data, and

generating digital signals comprising at least one of complex digital samples and real digital samples from the decoded network protocol data for distribution to the plurality of remote units, the digital signals including the call information.

7. A method comprising:

instructing a remote unit of a distributed antenna system to receive signals in a downlink band, wherein the remote unit receives uplink signals from mobile devices in a coverage area; and

sending a command from a master unit of the distributed antenna system to the remote unit regarding transmission of signals in the downlink band based on an analysis of the received signals by a self-optimized network analyzer in a unit of the distributed antenna system

selecting channels for use in the distributed antenna system at a self-optimized network controller based on database information and signals from a macro-cell environment processed by the self-optimized network analyzer, wherein the database information used for selecting the channels comprises a location of the distributed antenna system.

8. The method of claim 7, wherein instructing the remote unit to receive the signals in the downlink band comprises configuring a dedicated receiver of the remote unit for monitoring downlink bands, wherein an additional receiver of the remote units monitors uplink bands for the uplink signals simultaneously with the dedicated receiver monitoring the downlink bands.

9. The method of claim 7, wherein instructing the remote unit to receive the signals in the downlink band comprises by sending a command to the remote unit to tune a receiver from an uplink band to the downlink band.

10. The method of claim 7, further comprising:

receiving, by the master unit, call information in network protocol data from a network, decoding, by the master unit, the network protocol data, and generating, by the master unit, digital signals comprising at least one of complex digital samples and real digital samples from the decoded network protocol data for distribution to a plurality of remote units, the digital signals including the call information.
