Problems solved by technology

For example, DAS (Distributed Antenna System, Distributed Antenna System), the feeder loss and space propagation loss caused by 5G high frequency need to increase more head-end deployment points or RRU (Remote Radio Unit, radio frequency remote unit) source Pulling far to make up for it is basically impossible to implement
In order to support 4T4R, it is necessary to add 3 times more feeders and devices end-to-end on the existing 1T1R system, which cannot be realized in engineering and performance cannot be guaranteed

Abstract

The invention relates to an indoor distribution system, and the system comprises a DP subsystem which is used for receiving an uplink radio frequency signal transmitted by a terminal, converting the uplink radio frequency signal into a first uplink baseband digital signal, and transmitting the first uplink baseband digital signal to a Hub subsystem; an uplink radio frequency link of the DP subsystem comprises an antenna, an uplink amplifier and an uplink FPGA which are connected in sequence. The Hub subsystem is connected with the DP subsystem and used for converting the first uplink basebanddigital signal into a second uplink baseband digital signal and sending the second uplink baseband digital signal to the AU subsystem; the AU subsystem is connected with the Hub subsystem and used foranalyzing the second uplink baseband digital signal to obtain an uplink baseband signal and sending the uplink baseband signal to the GW subsystem; and the GW subsystem is connected with the AU subsystem, is connected with at least one core network of each operator in the plurality of operators, and is used for determining a target core network corresponding to the uplink baseband signal and sending the uplink baseband signal to the target core network. By adopting the indoor distribution system, co-construction and sharing of multiple operators can be realized, and the deployment difficultyand cost are reduced.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a room distribution system. Background technique [0002] As the 3GPP (3rd Generation Partnership Project, third generation partnership project) R15 version (Phase1, the first stage) was successfully frozen at the end of 2017, the pace of 5G (fifth generation mobile communication technology) is gradually approaching. Since 5G has three scenarios including eMBB (Enhance Mobile Broadband, enhanced mobile broadband), mMTC (massive Machine Type of Communication, massive machine type communication) and URLLC (Ultra Reliable&Low Latency Communication, low latency, high Reality, virtual reality) / AR (Augmented Reality, augmented reality), Internet of Vehicles, smart manufacturing, smart energy, wireless medical care, wireless home entertainment, connected drones and other applications, in the 5G era, 70% of business will take place indoors . 100Mbps anytime, anywhere wi...
