Indoor distribution system

Abstract

The invention discloses an indoor distribution system, including a base station near-end unit, which integrates 2G\3G\4G systems together, the light distribution unit includes an access optical port and an output optical port, and the access optical port directly Connect to the near-end unit of 2G\3G\4G base station through transmission optical cable or pigtail, and the output optical port of the optical distribution unit is directly connected to the expansion unit through the optical cable; the expansion unit includes access optical port, cascade optical port and output expansion optical port The access optical port in the expansion unit is connected to the optical distribution unit or the cascaded expansion unit through an optical cable, and the output expansion optical port is directly connected to the integrated remote unit through an optical cable or network cable. The cell splitting or merging of the indoor distribution system of the present invention is relatively simple, and the modification can be completed only through background software configuration. The networking is very flexible and can be adjusted at any time to merge / split cells according to the traffic tide demand of the scene.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an indoor distribution system. Background technique [0002] With the development of mobile communication networks, the mobile network scale and coverage depth of mobile communication operators are increasing. As an effective supplement to outdoor base stations and deep coverage of indoor signals, the construction of indoor distribution systems is currently being carried out very rapidly, and the number of some large cities has exceeded the number of outdoor base stations. This is mainly because when TD-LTE is used for dense urban coverage, there are many blind spots in the current TD-LTE outdoor macro base station coverage due to the limitations of site construction conditions, network planning and network optimization capabilities and other factors. In contrast, even in areas with good signal coverage, when the demand for traffic is high, it is necessary to increase the fre...

Problems solved by technology

[0007] From the above statistics, the traditional indoor distribution system mainly has the following problems, which can no longer meet the needs of network competition and development:

[0008] 1. It is difficult to construct and transform existing network rooms, the original components are aging, and fault detection and maintenance are difficult. It is difficult to increase the LTE network speed, and it is inconvenient to expand and evolve

We can only reduce the impact on network quality by strengthening design and construction management and strengthening the inspection and testing of original devices during construction and maintenance, but we cannot fundamentally solve indoor problems

[0009] 2. Large line loss: the traditional indoor distribution system uses a large number of feeders, which has a large loss, most of the power is wasted on the feeder lines, and the transmission efficiency is low

And there are some devices that are not up to standard, which affects the indoor coverage effect;
