A kind of 5g intelligent front-end system and using method thereof

Abstract

The present invention provides a 5G intelligent front-end system in the field of wireless communication, including a core network, an RRU, a digital / analog converter, a power amplifier group, a duplexer, and an active antenna array; the RRU One end is connected to the core network, and the other end is connected to the digital / analog converter and the active antenna array; one end of the power amplifier group is connected to the digital / analog converter, and the other end is connected to the duplexer; the The duplexer is connected to the active antenna array; the invention also provides a method for using the 5G intelligent front-end system. The invention has the advantages of improving the data transmission efficiency of 5G and reducing the network construction cost of 5G.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a 5G intelligent front-end system and a method of using the same. Background technique [0002] 5G is the fifth generation mobile communication technology, which is an extension after 4G. As a next-generation mobile communication network, the 5G network has a maximum theoretical transmission speed hundreds of times faster than the 4G network, and an entire ultra-high-quality movie can be downloaded within 1 second. Like 4G, 5G is a combination of long-term evolution technologies. The existing research results have allowed people to experience some of the features of 5G such as ultra-high speed, zero delay, ultra-large connection, and information fusion, but this is not 5G. With the continuous deepening of various researches, the key supporting technologies of 5G have been gradually clarified since 2017, and have entered the stage of substantive standardization resea...

Problems solved by technology

[0004] However, this communication mode will lead to the following problems under the 5G network: Since 5G mostly uses active antenna arrays, compared with the previous single antenna, the amount of data sent and received by the antenna will increase greatly, and the amount of data transmitted between the BBU and RRU will decrease. It is dozens or even hundreds of times that of the 4G network, which will bring unbearable pressure and challenges to the existing optical fiber transmission network, resulting in too long data delay, and the BBU must be placed in the computer room, making the network coverage cost too high
