The present disclosure is a novel utility of a software defined radio (SDR) based Distributed Antenna System (DAS) that is field reconfigurable and support multi-modulation schemes (modulation-independent), multi-carriers, multi-frequency bands and multi-channels. The present disclosure enables a high degree of flexibility to manage, control, enhance, facilitate the usage and performance of a distributed wireless network such as flexible simulcast, automatic traffic load-balancing, network and radio resource optimization, network calibration, autonomous/assisted commissioning, carrier pooling, automatic frequency selection, frequency carrier placement, traffic monitoring, traffic tagging, pilot beacon, etc.

1. A Distributed Antenna System (DAS) supporting Internet Protocol (IP) traffic and cellular traffic, the DAS comprising: a plurality of interconnected digital access units (DAUs), each DAU including a router configured to route IP traffic data and cellular traffic data to another DAU of the plurality of DAUs and at least one remote radio unit (RRU); andthe at least one remote radio unit (RRU) in communication with at least one DAU of the plurality of DAUs and configured to: transmit a first plurality of radio frequency (RF) signals associated with the IP traffic data to wireless subscribers; andtransmit a second plurality of RF signals associated with the cellular traffic data to wireless subscribers,wherein the at least one DAU is configured to transmit the IP traffic data and the cellular traffic data to each of the at least one RRUs via a communication path shared between the IP traffic data and the cellular traffic data. 2. The DAS of claim 1, wherein the at least one DAU is configured to receive the cellular traffic data from a base transceiver station (BTS) via an RF connection. 3. The DAS of claim 1, wherein the at least one DAU is configured to receive the cellular traffic data from a base transceiver station (BTS) via a repeater. 4. The DAS of claim 1, wherein the at least one DAU is configured to receive the cellular traffic data from a base transceiver station (BTS) via an optical connection. 5. The DAS of claim 1, wherein the shared communication path comprises an optical fiber cable. 6. The DAS of claim 1, wherein the at least one DAU is configured to create one or more data packets containing the cellular traffic data. 7. The DAS of claim 6, wherein the at least one DAU is further configured to create the one or more data packets in compliance with the Common Public Radio Interface (CPRI) standard. 8. The DAS of claim 1, wherein the at least one DAU is configured to create one or more data packets including the cellular traffic data and the IP traffic data. 9. The DAS of claim 8, wherein the at least one DAU is further configured to create the one or more data packets in compliance with the Common Public Radio Interface (CPRI) standard. 10. The DAS of claim 1, wherein a first RF signal of the second plurality of RF signals includes a first plurality of carriers. 11. The DAS of claim 10, wherein a second RF signal of the second plurality of RF signals includes a second plurality of carriers, and wherein the first plurality of carriers is different than the second plurality of carriers. 12. A method of supporting Internet Protocol (IP) traffic and cellular traffic by a Distributed Antenna System (DAS), the method comprising: receiving IP traffic data and cellular traffic data at one or more remote radio units (RRUs), the IP traffic data and the celular traffic data being routed from one or more of a plurality of interconnected digital access units (DAUs) via a communication path shared between the IP traffic data and the cellular traffic data;transmitting a first plurality of radio frequency (RF) signals associated with the IP traffic data to wireless subscribers; andtransmitting a second plurality of RF signals associated with the cellular traffic data to wireless subscribers. 13. The method of claim 12, wherein the one or more of the plurality of DAUs receive the cellular traffic data from a base transceiver station (BTS) via an RF connection. 14. The method of claim 12, wherein the one or more of the plurality of DAUs receive the cellular traffic data from a base transceiver station (BTS) via a repeater. 15. The method of claim 12, wherein the one or more of the plurality of DAUs receive the cellular traffic data from a base transceiver station (BTS) via an optical connection. 16. The method of claim 12, wherein the shared communication path comprises an optical fiber cable. 17. The method of claim 12, wherein the one or more of the plurality of DAUs create one or more data packets containing the cellular traffic data. 18. The method of claim 12, wherein the one or more of the plurality of DAUs create one or more data packets containing the cellular traffic data and the IP traffic data. 19. The method of claim 12, wherein a first RF signal of the second plurality of RF signals includes a first plurality of carriers. 20. The method of claim 19, wherein a second RF signal of the second plurality of RF signals includes a second plurality of carriers, and wherein the first plurality of carriers is different than the second plurality of carriers.
