Abstract

The invention discloses a power line transmission based mobile communication indoor microdistribution system which mainly solves the problems of high installation cost and high installation difficulty of an indoor communication system due to the fact that radio frequency cable incoming line communication connection is used in an indoor microdistribution system in the prior art. The power line transmission based mobile communication indoor microdistribution system comprises a micro front end and more than one micro rear end which are connected through power lines. By the scheme, various system communication signals are covered at the same time, and the system is simple in networking, convenient to install and low in cost and has high application and popularization values.

Description

technical field [0001] The invention relates to a micro-distribution system, in particular to an indoor micro-distribution system for mobile communication based on power line transmission. Background technique [0002] With the construction of office buildings, business centers, hotels and other office spaces, the indoor mobile user group is growing rapidly, and indoor users have higher requirements for conversational traffic and coverage. Therefore, optimizing indoor network coverage and quality and attracting the number of "hotspot" users will be the key for operators to gain a competitive advantage. [0003] From the perspective of network coverage, the indoor distribution system can effectively solve indoor blind spots and interference problems; from the perspective of network capacity, the indoor distribution system can effectively absorb traffic in indoor dense areas, improve system capacity, reduce the pressure on outdoor base stations, and reduce the number of outdoo...
