Problems solved by technology

[0002] As China's mobile communication market enters the 4G (fourth generation mobile communication) era, the traditional distributed coverage system has a very large difference in the transmission loss of different frequency signals, and it is difficult to meet the unified platform requirements for simultaneous access of multiple wireless communication networks
The large transmission loss makes the power of the signal source high, the electromagnetic radiation of the high-power radio frequency signal transmitted in the distribution system is large, the transmission power of the user terminal is large, and the difficulty of investment control and implementation coordination is prominent.

Embodiment Construction

[0024] The technical solutions of the present invention will be further specifically described below through examples in conjunction with the examples.

[0025] The distributed wireless signal coverage system of the embodiment of the present invention consists of three parts: a baseband signal processing unit BU, a radio frequency extension unit REU, and a radio frequency remote unit RU. Wherein, the baseband signal processing unit BU completes modulation and demodulation of service data to digital modulation signals. The radio frequency extension unit REU completes the mutual conversion between digital modulation signals and radio frequency signals, and the mutual conversion from radio frequency signals to analog light. The radio frequency remote unit RU completes the mutual conversion from analog light to radio frequency signals, as well as the power amplification and duplexing of radio frequency signals. Therefore, the present invention divides the base station in the prio...

Abstract

Provided is a distributed wireless signal coverage system. The system comprises a baseband signal processing unit, a radio frequency expansion unit and a radio frequency remote unit, wherein digital optical transmission is used between the baseband signal processing unit and the radio frequency expansion unit, and analogue radio-over-fibre transmission is directly used between the radio frequency expansion unit and the radio frequency remote unit. Compared with a traditional distributed coverage system, a radio frequency remote unit of the system is small in volume, low in costs and low in power consumption, is easy to place, and can more easily to implement refined coverage. The system of the present invention may be widely used in various types of mobile signal coverage application scenarios, such as large buildings, airports and stations, and both the total device cost and the installation and maintenance cost are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a distributed wireless signal coverage system. Background technique [0002] As China's mobile communication market enters the 4G (fourth generation mobile communication) era, the traditional distributed coverage system has a very large difference in the transmission loss of different frequency signals, and it is difficult to meet the requirements of a unified platform for simultaneous access to multiple wireless communication networks. The large transmission loss makes the signal source have high power, the electromagnetic radiation of high-power radio frequency signal is large when it is transmitted in the distribution system, the transmission power of the user terminal is large, and the difficulty of investment control and implementation coordination is prominent. Contents of the invention [0003] Aiming at the above-mentioned difficulties in the current indo...
