Benefits of technology

The present invention relates to a wireless communication system that uses Distributed Antenna Systems (DAS) in a distributed network. The DAS platform utilizes software defined radio (SDR) which simplifies the network architecture and reduces the cost of maintenance. This system design reduces hardware requirements, power consumption, and signal degradation. The technical effects of this invention include improved network flexibility, increased data-speed, and reduced signal degradation.

Problems solved by technology

Wireless and mobile network operators face the continuing challenge of building networks that effectively manage high data-traffic growth rates.

Embodiment Construction

[0031]A distributed antenna system (DAS) provides an efficient means of utilization of base station resources. The base station or base stations associated with a DAS can be located in a central location and / or facility commonly known as a base station hotel. A traditional DAS network includes one or more digital access units (DAUs) that function as the interface between the base stations and the digital remote units (DRUs). The DAUs can be collocated with the base stations. The DRUs can be daisy chained together and / or placed in a star configuration and provide coverage for a given geographical area. The DRUs are typically connected with the DAUs by employing a high-speed optical fiber link. This approach facilitates transport of the RF signals from the base stations to a remote location or area served by the DRUs. A typical base station comprises 3 independent radio resources, commonly known as sectors. These 3 sectors are typically used to cover 3 separate geographical areas with...

Abstract

A system for routing signals in a Distributed Antenna System (DAS) includes one or more Base Band Units (BBUs). Each of the one or more BBUs has one or more digital outputs. The system also includes a plurality of Digital Multiplexer Units (DMUs) coupled to each other and operable to route signals between the plurality of DMUs. Each of the plurality of DMUs is operable to receive one or more digital inputs from the one or more BBUs. The system further includes a plurality of Digital Remote Units (DRUs) coupled to the plurality of DMUs and operable to transport signals between the plurality of DRUs and one or more of the plurality of DMUs.
