Problems solved by technology

If the current communication base station is used to carry out 3G, the signal-to-noise ratio and sensitivity of the base station will be seriously reduced, and the coverage of the 3G signal will be relatively reduced, forming a 3G signal shadow area (such as figure 1 As shown), it is impossible to achieve seamless coverage of 3G signals
At present, there is no literature report on the technology and method of upgrading existing wireless communication base stations to achieve 3G seamless coverage

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] In the microwave communication system, taking CDMA base station as an example, the main equipment and components of the base station include: outdoor antenna, duplexer, filter, switch, power supply and other control systems.

[0016] figure 1 It is a schematic diagram of a CDMA base station provided by the present invention. figure 1 The switch shown in is an important device of the base station, where a large amount of information is processed. In the figure, 4 represents the outdoor antenna of the base station, S1 and S2 respectively represent the signal main input end and the signal standby input end of the receiving front section of the base station, and 1 and 2 represent the first signal input end (also called the main signal input end) of the base station switch respectively. ) and the second signal input terminal (also called standby signal in...

Abstract

The invention relates to a method for upgrading existing wireless communication base stations and realizing 3G seamless coverage, belonging to the technical field of communication. The construction of a 3G network consumes a large amount of resources, and if sites of the original 2G base stations or the CDMA base stations are used for directly reconstructing equipment, the investment can be greatly saved. However, because the 3G frequency is higher, if the 3G equipment is directly erected at the existing sites, blind areas which can not be covered can appear in the original sites. The invention provides a method for eliminating the blind areas, which enables a filter in the receiving front end of the existing base station to be combined with the superconducting filtering technique, thereby improving the receiving sensitivity of the base station to the maximum extent, simultaneously inhibiting in-band and out-off-band signal interference and background noise interference of 3G signals, greatly improving the signal-to-noise ratio of the receiving front end, effectively expanding the coverage area of the 3G signals, and realizing the seamless coverage of the 3G signals.

Description

technical field [0001] The invention relates to a method for merging superconducting filtering technology with the receiving front end of an existing wireless communication base station to realize seamless coverage of 3G signals, which belongs to the technical field of communication. Background technique [0002] With the launch of 3G commercial use, a new round of 3G base station construction has been gradually launched. Facing the upcoming climax of 3G base station construction, major operators have invested a lot of money and the government has issued various regulations to ensure the smooth progress of base station construction. However, telecom operators generally feel that there are three difficulties in the construction of new 3G base stations: "difficult in site selection, difficult in construction and difficult in maintenance". Relevant experts suggest: TD network construction should make full use of existing base stations, TD and existing wireless communication ba...
