Description

technical field [0001] The invention is a wireless communication relay transmission technology, which is suitable for relay transmission of a wireless communication system in a weak field section, and belongs to the technical field of wireless communication. Background technique [0002] In the current wireless system, there are many kinds of wireless communication systems, such as GSM, CDAM, WCDMA, TD-SCDAM, CDMA2000 and other wireless communication systems. In the existing technology, there are dedicated optical fibers for the above wireless communication systems. The repeater is used as a relay device, but due to some special areas and tunnels, due to the limitations of the antenna installation space and the number of optical fibers brought about by its location and building boundaries, the network planning of each wireless communication system is inconsistent, and the network planning of each system is inconsistent. Influenced by factors such as base station location, op...

[0002] In the current wireless system, there are many kinds of wireless communication systems, such as GSM, CDAM, WCDMA, TD-SCDAM, CDMA2000 and other wireless communication systems. In the existing technology, there are dedicated optical fibers for the above wireless communication systems. The repeater is used as a relay device, but due to some special areas and tunnels, due to the limitations of the antenna installation space and the number of optical fibers brought about by its location and building boundaries, the network planning of each wireless communication system is inconsistent, and the network planning of each system is inconsistent. Influenced by factors such as base station location, optical transmission route length, inconsistent user distribution, mutual interference, and isolation requirements between systems, all relay equipment cannot be installed in these areas to meet the requirements of each wireless communication system. Therefore, the existing optical fiber repeaters cannot meet the relay communication requirements for each wireless communication system user in this type of area
