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...
