Embodiment Construction

[0030] The present invention is a novel reconfigurable distributed antenna system that provides a high degree of flexibility to manage, control, reconfigure, enhance and facilitate radio resource efficiency, usage and overall performance of a distributed wireless network. figure 1 An embodiment of a distributed antenna system 100 according to the invention is shown. The system utilizes a digital access unit function 105 (hereinafter referred to as "DAU"). DAU 105 serves as an associated base station (BTS) 110A-B with a plurality of digital remote units (DRU) 125A-n (although in figure 1 Only the interfaces between the 4 DRUs are shown in . Although those skilled in the art will recognize that a DRU communicates with a DAU and an RRU communicates with a base station, because of the similarity of functionality discussed herein, "DRU" may be used in this specification with a remote radio head unit or "RRU". used interchangeably. In addition, those skilled in the art should rec...

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. More specifically, the present invention relates to a DAS utilizing one or more Daisy-Chained Rings of Remote Units. 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.

Description

[0001] related application [0002] This application claims the benefit of the following US patent applications, all of which are hereby incorporated by reference in their entirety. [0003] technical field [0004] The present invention generally relates to wireless communication systems employing distributed antenna systems (DAS) as part of a distributed wireless network. More specifically, the present invention relates to a DAS utilizing one or more remotely monitored and controlled digital access units configured to assign specific packet transmissions to selected ones of a plurality of remote units, wherein the The remote units may, in some embodiments, be configured in a daisy-chained ring. Background technique [0005] Wireless and mobile network operators face the ongoing challenge of building networks that efficiently manage high data traffic growth rates. Increased levels of mobility and multimedia content for end users require end-to-end network adaptation to...
