Base station carrier wave distributor and communication network composed thereof

Abstract

The invention relates to base station carrier wave distributors and the communication network composed of the distributors. The base station carrier wave distributors comprise local terminal equipment and remote terminal equipment, and the local terminal equipment consists of up and down intermediate frequency converters, signaling combiners and splitters, radio frequency up and down converters, radio frequency filters, automatic radio frequency gain controllers, up and down power amplifiers, pilot frequency signal generators, pilot frequency signal separation detectors, diplexers and radio frequency transmitting / receiving antennas. The remote terminal equipment is similar with the local terminal equipment, and intermediate frequency power amplifiers and intermediate frequency low noise amplifiers are increased. The radio frequency signal of the base station is frequency-converted by the local terminal equipment, and the radio frequency signal is sent to the remote terminal equipment;the radio frequency signal is then frequency-converted by the remote terminal equipment into the intermediate frequency signal and sent to the cell phone subscriber. The central base station of the communication network composed of the base station carrier wave distributors is provided with a plurality of base station carrier wave distributors, and the covered area is enlarged by tens times. The superior and inferior base station carrier wave distributors with identical carrier wave signal are in relay connection relation, to realize complicated and flexible base station signaling coverage. The networking expense is saved, and the networking speed is improved.

Description

technical field [0001] The invention relates to mobile communication base station equipment and a communication network thereof, in particular to a base station carrier allocator and a communication network assembled therewith. Background technique [0002] The number of mobile communication users is increasing, and users' requirements for network capacity and call quality are further improved, and the requirements for seamless coverage of signals are urgent. This requires operators to continuously subdivide micro cells and increase the number and density of base stations. [0003] Because the indoor unit of the base station equipment and the transmitting antenna in the traditional base station are connected by a high-frequency, low-loss feeder tube of the radio frequency feeder, limited by the radio frequency feeder, the distance between the indoor unit of the base station and the transmitting antenna can only be tens of meters . In order to expand the coverage area, base...
