Abstract: According to an embodiment of the present invention, a network is provided. The network may include a first base transceiver station (BTS). The first BTS may be operable to provide a first signal including a plurality of first carriers. The network may also include a second BTS operable to provide a second signal including a plurality of second carriers. The network may also include a set of one or more digital access units (DAUs), each of the one or more DAUs being coupled to at least one of the first BTS or the second BTS. A set of one or more digital remote units (DRUs) may be included in the network, each of the DRUs being coupled to one of the one or more DAUs and operable to broadcast the first signal or the second signal.

Abstract: 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.
