Problems solved by technology
[0004] However, with the gradual popularization of 5G, 5G networks adopt MIMO technology (multiple streams on the same frequency, 85% of the current network scenarios are single-cable single-stream systems), and users change mobile services such as speed and capacity. Traditional DAS is facing huge challenges. challenge

The present invention relates to the technical field of wireless communication, in particular to radio frequency signal coverage wireless communication equipment based on 4T4R single-wire transmission. It includes a 5G core network, a 5G baseband and an extension unit, the output of the 5G core network is connected to the input of the 5G baseband, and the output of the 5G baseband is connected to the input of the extension unit, characterized in that: the extension The output end of the unit is connected with an extended ERU, and the output end of the extended ERU is connected with an enhanced DRU. In the present invention, the frequency conversion and combination of radio frequency signals are realized through the cooperation of the set radio frequency unit with the extended ERU and the enhanced DRU, thereby reducing the number of digital chips used, lower hardware costs, and a more secure supply chain, and the extended ERU itself can also utilize Eight enhanced DRU units are hung under a single feeder of the old original indoor distribution system for extended coverage. On the basis of realizing the single feeder transmission of 4T4R 5G signals, the coverage area is equivalent to more than 8 times the coverage area of conventional 5G remote units.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to radio frequency signal coverage wireless communication equipment based on 4T4R single-wire transmission. Background technique [0002] Operators in China immediately launched large-scale construction of 5G macro stations. However, due to the particularity of the 5G frequency band, indoor signal coverage is more difficult than 4G. At the same time, various problems such as construction difficulty, investment cost, and coverage effect have become increasingly prominent. [0003] At present, domestic operators still mainly use traditional DAS to solve the indoor coverage problem. Traditional DAS mainly uses passive devices, and the industrial chain is mature. It has the advantages of small investment, low failure rate, simple and effective system, and multi-system expansion can be carried out by combining circuits in the later stage. advantage.
