Description

Technical field: [0001] The present invention relates to the field of wireless communication, in particular to a network optimization device in the field of wireless communication. Background technique: [0002] With the continuous development of domestic mobile communication services, the coverage of wireless communication networks is also expanding. Villages, towns, mountains and islands, and many areas that did not have signal coverage before, can now use mobile communication equipment well. However, with the increasing number of high-end wireless services provided by wireless operators, people's requirements for the quality of wireless networks are also increasing.

Problems solved by technology

Moreover, due to the continuous development of various buildings and traffic roads, there are still some weak links in the indoor wireless communication signals in some specific areas that cannot meet the needs of users. At present, there are mainly the following problems:

[0003] 1. Weak area: mainly because the signal is close to the receiving sensitivity of the mobile phone after loss, resulting in poor communication on the mobile phone

[0004] 2. Blind area: the signal is lower than the mobile phone receiving sensitivity after loss, resulting in poor mobile phone calls

[0005] 3. Conflict zone: Mainly the wireless signals in high-rise building areas come from multiple cells, and most of them are unstable reflection signals on the ground and walls, resulting in frequent switching (ie ping-pong effect), which seriously affects the normal communication of mobile phones

[0009] 1. Cost problem: These areas are sporadic branches, and there are a lot of them. It is basically impossible to cover them uniformly. Therefore, it is necessary to build a large number of repeaters and invest a lot

[0010] 2. Network optimization problem: even in order to solve the signal coverage of these small blind areas, multiple repeaters are connected in the same base station cell regardless of cost, but the noise interference of these repeaters to the uplink of the base station will be serious, so it is necessary to Carry out careful network optimization design

[0011] The power link of most indoor distribution systems is designed according to a single carrier frequency. The access of the 3G base station enables the repeater and the dry amplifier to amplify one or more carrier frequencies, and each carrier brings 3dB (double power) output power. This will lead to insufficient indoor edge field strength, frequent switching and unstable 3G data services, and the cost of upgrading the high-power amplifier as a whole is unacceptable
