Novel multi-network-integrated indoor distribution system

Abstract

The invention relates to a novel multi-network-integrated indoor distribution system. The novel multi-network-integrated indoor distribution system comprises an access unit, an extension unit and a remote end unit, wherein the access unit, the extension unit and the remote end unit transmit signals through digital optical fibers; the access unit can couple multiple downlink radio-frequency (RF) signals from RRUs (Radio Remote Units) of different systems, and the downlink RF signals are converted into baseband digital signals after the downlink RF signals pass through a digital processing unit; the access unit can receive downlink baseband signals from BBUs (Building Baseband Units) of different systems, and the downlink baseband signals can be transmitted together with the baseband digital signals, which are received and processed by an RF coupling port, after the downlink baseband signals pass through the digital processing unit. The novel multi-network-integrated indoor distribution system has the beneficial effects that indoor signal coverage is realized by adopting information source access, digital optical fiber transmission and remote coverage; and the access unit supports signal access of multiple network types and supports signal access of multiple forms. The invention discloses a multi-network-type signal access and coverage system, and repeated construction is avoided, so that the system is energy-saving and environment-friendly; meanwhile, the system supports the signal access of multiple forms, so that network construction is more flexible and convenient.

Description

technical field [0001] The invention relates to the field of indoor coverage of mobile communication networks, and is a novel multi-network fusion indoor distribution system. Background technique [0002] In order to solve the problem of indoor coverage of radio signals, the most effective method at present is to build an indoor distribution system to introduce base station signals into every indoor area, thereby eliminating indoor coverage blind spots and providing indoor users with stable and reliable radio signals. Users enjoy high-quality communication services. [0003] With the development of wireless communication, networks of multiple standards such as 2G / 3G / 4G need indoor coverage at the same time. The traditional coverage method is an indoor distribution system based on repeaters or radio frequency remote units (RRU). Each device can only support one network standard, and it is impossible to use a set of devices to realize multiple standard networks such as 2G / 3G / ...

The traditional coverage method is an indoor distribution system based on repeaters or radio frequency remote units (RRU). Each device can only support one network standard, and it is impossible to use a set of devices to realize multiple standard networks such as 2G / 3G / 4G. transmission and coverage, which directly leads to an increase in the cost of the entire network construction
