Mobile communication base station and installation method thereof

Abstract

The invention discloses a mobile communication base station, and relates to a communication tower. The mobile communication base station is used for solving the problems that an uplink and a downlink of an antenna are unbalanced and meanwhile, the antenna is large in uplink noise, small in uplink gain and weak in antenna receiving performance. The mobile communication base station comprises a tower body, a first platform positioned at the upper part of the tower body, and a second platform; the second platform is arranged below the first platform; the first platform comprises an upper fixed steel ring, a lower fixed steel ring, a separation steel ring and a sliding groove; the sliding groove comprises an upper groove and a lower groove; the upper groove is formed on the lower end face of the upper fixed steel ring; the lower groove is formed on the upper end face of the lower fixed steel ring; the upper fixed steel ring and the lower fixed steel ring are connected by a safety pin on the separation steel ring; the sliding groove is a double-slide-rail groove; and the second platform and the first platform are of the same structure. Balance of the uplink and the downlink of an antenna device is ensured, and meanwhile, effects of reducing uplink noise of the antenna device, promoting the uplink gain and improving receiving performance of the antenna device are achieved.

Description

technical field [0001] The invention relates to a communication tower, in particular to a mobile communication base station and an installation method thereof. Background technique [0002] Communication base station, that is, public mobile communication base station is a form of radio station, which refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication switching center in a limited radio coverage area. The base station is the basic unit that forms a cell in mobile communication, and completes the communication and management functions between the mobile communication network and mobile communication users. Generally, base station antennas are installed on buildings or transmission towers 15-50 meters above the ground. [0003] Patent document CN 103883153B (application date: 2014.03.04) discloses a single-pipe tower, including a base part, a main body part joined to the base part, and a protective dev...

Problems solved by technology

[0005] However, the above scheme has the following disadvantages. On the one hand, the bandwidth occupied by users sending data through the Internet is a quarter of the bandwidth occupied by receiving data. The vacancy of the channel causes waste of channel resources, the uplink and downlink of the antenna are unbalanced, and the uplink noise of the antenna is large, the uplink gain is small, and the antenna receiving performance is weak; on the other hand, when the polarization direction of the receiving antenna (such as horizontal or right-handed circular polarization) is completely orthogonal to the polarization direction of the incoming wave (corresponding to vertical or left-handed circular polarization), the receiving antenna will not receive the energy of the incoming wave at all, and the incoming wave is said to be isolated from the polarization of the receiving antenna. , and the adjustment range of the polarization direction of the above technical scheme is too narrow
