Title:
NETWORKING SYSTEM FOR INDOOR COVERAGE OF TIME DIVISION DUPLEX SYNCHRONOUS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/148720
Kind Code:
A1
Abstract:
A networking system for indoor coverage of time division duplex synchronous system is provided in the present invention, which comprises a Base Band Unit (BBU), multiple Remote Radio Units (RRUs), and multiple ceiling antennas, wherein, the BBU connects with the RRU through a fiber interface. Each RRU has two independent channels. Each independent channel at least comprises a fiber interface, a digital intermediate frequency unit, a transceiver, a power amplifier/low noise amplifier and a filter which are connected in turn. Each independent channel also solely connects with some ceiling antennas. Compared with the existing single channel coverage, the dual channels coverage of the present invention have diversity gain because two channels are independent in space, and the solution of the present invention which performs a partitional coverage for indoor area enhances the capacity of the indoor system, it is especially adaptive for an application in large supermarket, exhibition centre or stadium. A verification for the present invention shows that the solution can greatly promotes the system capacity, and the promoted quantity approaches 100%.
