Abstract
The invention discloses a mobile communication indoor microdistribution system, which mainly solves the problems that in the prior art, the system structure of the indoor distribution system is complicated, the system cost is higher, the installation is difficult, the cost performance is not high, and the market popularization cannot be easily realized. The mobile communication indoor microdistribution system comprises a micro front end and more than one micro back end connected with the micro front end, wherein the micro front end comprises a first duplexer, a forward low-noise amplifier, a forward input filter, a forward lower frequency converter, a forward analog-to-digital converter, a forward ICS (Internet connection sharing) processing module, a forward digital-to-analog converter, a forward upper frequency converter, a reverse lower frequency converter, a reverse analog-to-digital converter, a reverse ICS processing module, a reverse digital-to-analog converter, a reverse upper frequency converter, a reverse output filter and a reverse power amplifier in sequential connection. Through the scheme, the mobile communication indoor microdistribution system reaches the goals that the simultaneous coverage of multi-system communication signals is realized, in addition, the networking is simple, the installation is convenient, the cost is low, and high practical values and popularization values are realized.
Description
technical field [0001] The invention relates to a micro-distribution system, in particular to a micro-distribution system in a mobile communication room. 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 outdoor base stations. In terms of netw...
