The invention discloses a non-line-of-sight relay communication system based on LTE. The system includes a first LTE system, a second LTE system, a first relay cell, a second relay cell and a relay terminal. The first LTE system is in respective communication connection with first user equipment and the first relay cell. The first relay cell is in communication connection with the relay terminal.The relay terminal is in communication connection with the second relay cell. The second relay cell is in communication connection with the second LTE system. The second LTE system is in communicationconnection with second user equipment. According to the system, non-line-of-sight wireless link communication can be realized, communication distance is long, wider transmission bandwidth can be provided, costs are low, and at the same time, the used relay terminal is small in volume, light in weight, and low in power consumption. The system can adapt to use of various environments.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an LTE-based non-line-of-sight relay communication system. Background technique [0002] Current microwave and wireless bridges and other equipment can only support line-of-sight communication, and cannot establish a communication link between two places that are not reachable by line-of-sight, and the communication distance is limited, requiring multiple hops to achieve long-distance relay, and the cost is too high , The engineering construction is very difficult. Although satellite communication can realize relevant functions, it is expensive and has low bandwidth, which cannot meet the needs of low-cost applications. Contents of the invention [0003] In order to overcome the defects existing in the background technology, the object of the present invention is to provide a non-line-of-sight relay communication system based on LTE, constructing a relay cell by a...
