Embodiment Construction

[0024] refer to figure 1 , the present invention consists of a forwarding unit 1, a first radio frequency front end 2, a second radio frequency front end 3, and first to sixth antennas 4, 5, 6, 7, 8, 9 for transmitting and receiving. figure 1 It is a functional block diagram of the present invention.

[0025] The base station sends, the terminal receives direction:

[0026] In the uplink, the radio frequency modulation signal output by the LTE base station is sent to the first radio frequency front end 2 and transmitted through the third antenna 6; in the air part, the first antenna 4 receives the radio frequency modulation signal into the forwarding unit 1, and the forwarding unit 1 transmits the radio frequency modulation signal The signal is converted into an inter-frequency modulation signal and sent out through the second antenna 5; in the downlink, the sixth antenna 9 receives the inter-frequency modulation signal into the second radio frequency front-end 3, and the sec...

Abstract

The invention discloses an air repeater for an LTE base station. The air repeater comprises a forwarding unit, a radio frequency front end and a transmitting/receiving antenna. Signals are forwarded after distortion-free spectrum shifting and amplification in air, and then the received spectra are restored on the ground to realize forwarding of the LTE signals. Moreover, the system has the advantages of low cost, simple erection, strong maintainability, low power consumption, high reliability and the like, and the air forwarding unit is flexible in erection position, thereby solving the problem that the erection cost of the base station in blind area coverage as well as some remote regions and regions with few users is too high; a variable gain amplifier with a large dynamic range is integrated inside to achieve long-distance and near-distance coverage; the transmitting and receiving time slots are automatically switched, the switching time can be ignored, and data loss caused by the switching delay will not occur; and the variable range of the frequency of each part in the system is wide, the frequency band is convenient to change for forwarding, only the filter frequency band needs to be correspondingly changed, and the expandability and the universality are strong.

Description

technical field [0001] The invention relates to an air transponder of an LTE base station in the field of communication, which is suitable for TDD-LTE communication systems in the field of microwave communication, where the coverage signal quality is poor, or the coverage is blind, and the special terrain is inconvenient to set up the communication system of the base station. Background technique [0002] Good wireless coverage is a prerequisite for ensuring the quality and indicators of communication networks. Due to the influence of the terrain environment and power level, there will be weak signal areas or blind areas in the wireless broadcast signal coverage area. For example, there are many buildings in the city, and there are a large number of weak and blind areas on the ground; moreover, in some remote areas and areas with few users, the cost of setting up base stations is too high. The digital transponder can receive the transmitted signal first, demodulate it, and ...
