Abstract

The invention relates to radio modem and TD-LTE systems in the field of wireless communication, and specifically relates to a radio modem and power TD-LTE private network common antenna system and an implementation method thereof. The system comprises a radio modem base station and a power TD-LTE private network base station. A common combiner is arranged at the output ports of the radio modem base station and the power TD-LTE private network base station. The output of the common combiner is connected with an antenna for realizing a transceiver common antenna of the radio modem base station and the power TD-LTE private network base station. The invention also provides the implementation method of the radio modem and power TD-LTE private network common antenna system. According to the invention, by adding the combiner, radio frequency signals of the radio modem and the power TD-LTE are transmitted through a set of antennas. According to the invention, the existing base station site of the radio modem and an antenna feed system are utilized, the power TD-LTE and radio modem common site common antenna construction can be realized, and the network construction cost can be effectively reduced.

Description

technical field [0001] The invention relates to a data transmission station and a TD-LTE system in the field of wireless communication, in particular to a system in which a data transmission station and a power TD-LTE private network share an antenna and an implementation method thereof. Background technique [0002] Common antenna technology for wireless communication systems is used in both the second-generation wireless communication system and the third-generation wireless communication system, especially in multiple wireless communication systems working in the same frequency band. equipment cost and construction cost. [0003] In the field of electric power wireless private network, the common antenna technology of multiple communication systems has not been used yet. At present, the electric power wireless private network has a variety of communication systems such as digital transmission stations and electric power TD-LTE private network. Both systems use the 230MHz...
