Problems solved by technology

Some merchants increase the sensitivity of uplink reception by adding tower-mounted amplifiers, but ignore the downlink power matching problem, resulting in an imbalance between the downlink transmitted signal and the uplink received signal, resulting in high call drop rates, low voice quality, and even inability to connect.
In addition, during construction, at least one new antenna feeder system must be added to install the tower top amplifier, which can easily cause the deterioration of the antenna feeder system indicators, and the disadvantages of high construction cost, long construction period, and special maintenance are required

Embodiment Construction

[0017] Below we describe the present invention in more detail in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to figure 1 , figure 2 A base station signal optimization system includes a base station transceiver station, a dual-polarization antenna, and two duplexers, a power amplifier unit, a high-power duplexer, a feed unit, and two duplex tower amplifiers. The duplexer, power amplifier unit, high-power duplexer, feed unit, and duplex tower amplifier form two communication links between the base transceiver station and the dual-polarized antenna in the same connection mode. Among them, the combining end of the duplexer is connected in series with the base transceiver station, the power amplifier unit is connected to the TX end of the duplexer, the high-power duplexer is connected to the output end of the power amplifier unit and is connected to the RX end of the duplexer, and the output end of the power amplifier unit is connected to t...

Abstract

The invention relates to an optimization system and a method thereof for a base station signal. Based on the structure of the original antenna feed system, two duplexers, two power amplifier units, two feeding units, high-power duplexers and two tower amplification module duplexers are additionally arranged between a receiving and transmitting signal station of a base station and a duapolarization antenna, and the same connection mode is used for forming two communication links between the receiving and transmitting station and the duapolarization antenna. The coverage range of the base station signal is enlarged, and the blind area of the base station is reduced by amplifying a downlink signal and improving the uplink receiving sensitivity to display the performance of the base station in maximum.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a system for optimizing base station signals in the field of mobile communication and an implementation method thereof. Background technique [0002] The rapid development of the mobile communication business has brought about a continuous increase in the number of mobile communication users. On the one hand, with the high-rise urban construction, high-rise buildings are constantly emerging. Due to the shadow effect of wireless transmission, mobile communication often forms behind these high-rise buildings. The dead zone of the communication signal. On the other hand, due to the complex and vast terrain in rural areas, base stations are often elevated, which not only increases the cost of base station construction, but also increases signal transmission loss and reduces signal coverage after the antenna is elevated. It can be seen that there is an urgent need to increase the ...
