Abrégé

A system for routing signals in a Distributed Antenna System includes a plurality of Digital Access Units (DAUs) and a plurality of Digital Remote Units (DRUs). The plurality of DAUs are coupled and operable to route signals between the plurality of DAUs. The plurality of DRUs are coupled to the plurality of DAUs and operable to transport signals between DRUs and DAUs. The system also includes a plurality of Base Transceiver Stations (BTS) and a plurality of Base Transceiver Station sector RF connections coupled to the plurality of DAUs and operable to route signals between the plurality of DAUs and the plurality of Base Transceiver Stations sector RF port connections. The system further includes one or more delay compensation merge units operable to delay signals transmitted from or received by each of the plurality of DRUs.

Abrégé

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 invention 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. As a result, a DAS in accordance with the present invention can increase the efficiency and traffic capacity of the operators' wireless network.
