5G wireless communication indoor distribution system with redundant backup and implementation method thereof

Abstract

The invention provides a 5G wireless communication indoor distribution system with redundant backup, and also provides an implementation method of the system, the equipment in the indoor distribution system is backed up, when the equipment breaks down, automatic switching can be realized, the communication reliability is powerfully guaranteed, and the system comprises a DU (Data Unit) for baseband signal processing, wherein the DU equipment is connected with the EU equipment; EU equipment which is used for expansion connection, wherein the EU equipment is connected with a plurality of RU equipment; and RU equipment used for transmitting and receiving wireless signals. The system is characterized in that a backup EU device is arranged corresponding to each EU device, the RU devices are respectively connected to the backup EU devices, the backup EU devices are connected with the DU devices, each RU device connected with the EU devices is respectively and correspondingly provided with a backup RU device, the backup RU devices are correspondingly connected with the EU devices, and the backup RU devices are respectively connected to the corresponding backup EU devices.

Description

technical field [0001] The invention relates to the technical field of 5G wireless communication, in particular to a 5G communication indoor distribution system with redundant backup and an implementation method thereof. Background technique [0002] With the rapid increase of mobile users and more and more high-rise buildings in cities, the traffic density and coverage requirements are also rising. These buildings are large in size and have a strong shielding effect on mobile phone signals. In the environment of low floors of large buildings, underground shopping malls, underground parking lots, etc., the mobile communication signal is weak, and the mobile phone cannot be used normally, forming a blind area and shadow area of ​​mobile communication; on the middle floor, due to the overlapping of signals from different surrounding base stations, It causes pilot frequency pollution, frequent switching of mobile phone signals, and even dropped calls, seriously affecting the n...

AI Technical Summary

Problems solved by technology

In the environment of low floors of large buildings, underground shopping malls, underground parking lots, etc., the mobile communication signal is weak, and the mobile phone cannot be used normally, forming a blind area and shadow area of ​​mobile communication; on the middle floor, due to the overlapping of signals from different surrounding base stations, Causes pilot pollution, frequent switching of mobile phone signals, and even dropped calls, seriously affecting the normal use of mobile phones

In addition, in some buildings, although the mobile phone can communicate normally, the user density is high, the base station channel is crowded, and the mobile phone is difficult to go online.
