Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a reverse interference positioning method, system, wireless signal collection entity and device on the side of a wireless access system. Background technique [0002] Generally, the frequency bands involved in the wireless access system are very rich. For example, the Code Division Multiple Access (CDMA) system involves 13 frequency bands and more than 140 sub-segments, which are distributed between 400M and 2100M. Abundant frequency bands expand the application range of wireless access systems, but at the same time, they also bring some problems. Due to the particularity of wireless resources, the frequency allocation methods adopted by various countries are different, especially in the widely used 450M frequency band, there are many complex allocation methods. Typical applications in this frequency band include: wireless walkie-talkies, digital transmission stations ...

AI Technical Summary

Problems solved by technology

[0004] 1) It is difficult for user terminals to access

The existence of reverse interference reduces the reverse sensitivity and reduces the reverse coverage distance, thus making it difficult for user terminals to access

[0005] 2) The front and back are unbalanced, so that the user terminal shows that there is a signal but the call cannot be realized

[0006] 3) The transmission power of the user terminal is high, the power consumption is large, and the system capacity is reduced

[0010] A. When the wireless environment is complex, it may take a long time to collect wireless signals without interruption, and it is difficult to complete this task manually, especially in areas with poor climate environment, such as mountain stations or desert areas

[0011] B. When manually using interference detection equipment for wireless signal collection, if the spatial positions of the spectrum analyzer and the system antenna are inconsistent, it will cause errors in monitoring results and increase the difficulty of problem location, especially in hilly or mountainous areas

[0012] It can be seen from the above description that the reverse interference detection and positioning method in the prior art is not only difficult to implement, but also is seriously affected by environmental and human factors, and the accuracy of reverse interference detection and positioning is difficult to guarantee
