Description
Technical field
The bright communication field that belongs to of this law relates to the micro-power repeater that a kind of wireless environment is monitored.
Background technology
The repeater is a kind of mobile network base station covering deficiency that is used for remedying, and enlarges base station range, fills a kind of extremely effectively equipment of coverage hole.The repeater generally is mainly used in and solves the signal covering that base station range is interior or the base station covers movable signal blind area, edge.Fast development along with domestic mobile communications network, network coverage constantly enlarges, but because the continually developing of various buildings, traffic route, so that indoor wireless communication still exists some weak links can not satisfy user's demand, mainly has following problem at present:
1, weak district: mainly be signal through after the loss near the mobile phone receiving sensitivity, cause mobile phone communication bad;
2, blind area: signal is lower than the mobile phone receiving sensitivity through after the loss, causes mobile phone communication bad;
3, battleground: mainly be skyscraper zone wireless signal from a plurality of sub-districts, and mostly be the unstable reflected signal of ground, metope, cause frequent switching (being ping-pong), have a strong impact on the proper communication of mobile phone;
4, busy district: mainly be the big area of telephone traffic, the base station capacity is difficult to satisfy communication requirement, and the user can't carry out proper communication by access to mobile network;
5, little blind area: the coverage hole that area is smaller.
And, the monitoring of wireless network many index is undoubtedly the primary problem that solves of operator along with the expansion with the user of developing rapidly of communication network.
Traditional wireless environment test mode exists following defective:
1, the wireless environment test job is subjected to personnel amount and energy to limit bigger
2, working strength is big, network optimization engineer's all-the-way tracking, inefficiency;
3, test time is limited, and is ineffective for the bursting problem monitoring;
4, only from network data analysis, can't really react the impression of user to network quality;
5, the test data utilance is low, and data storing is unfavorable;
6, testing location is comparatively fixing, is unfavorable for comprehensive reaction network situation;
7, test job is subjected to the engineer individual engineering experience person in charge to influence bigger;
8, testing equipment is of a great variety, form and standard disunity.
Based on above reason, be badly in need of setting up a set of equipment, effectively coverage hole in the decontamination chamber, suppress interference, for indoor mobile communication subscriber provides stable, reliable signal, make the user indoor also can the enjoy high quality personal communication service.Simultaneously, again can automatical and efficient rate carry out wireless network monitoring and analyze aid operators to carry out network operation, optimization work automatically.
Summary of the invention
For solving above-mentioned existing in prior technology weak point, order of the present invention provides a kind of micro-power repeater that is used for the wireless environment monitoring, and the present invention is achieved through the following technical solutions:
