REMOTELY RECONFIGURABLE DISTRIBUTED ANTENNA SYSTEM AND METHODS
First Claim
1. A Distributed Antenna System (DAS) supporting Internet Protocol (IP) traffic and cellular traffic, the DAS comprising:
- a digital access unit (DAU) configured to receive IP traffic data and cellular traffic data; and
at least one remote radio unit (RRU) in communication with the DAU and configured to;
transmit a first plurality of radio frequency (RF) signals associated with the IP traffic data to wireless subscribers; and
transmit a second plurality of RF signals associated with the cellular traffic data to wireless subscribers,wherein the DAU is configured to transmit the IP traffic data and the cellular traffic data to each of the at least one RRUs via a shared communication path.

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.
