Problems solved by technology

For example, due to the shadow effect of wireless propagation, blind areas of mobile communication signals are often formed behind or in the middle of high-rise buildings; The main lobe has a large downtilt angle, so that the upper and middle parts of high-rise buildings generally cannot receive signals effectively; in addition, due to the shielding effect of buildings on electromagnetic waves, tunnels, subways, underground shopping malls, entertainment cities, parking lots, and hotels, In some closed large buildings such as office buildings, mobile communication signals cannot be received normally.

Embodiment Construction

[0020] The present invention is further described as follows in conjunction with accompanying drawing:

[0021] As shown in Fig. 1 and Fig. 2, it is a kind of mobile communication broadband repeater of the present invention, and it is a repeater system synchronous with the mobile communication wireless system, and it has a repeater host computer, is used for signal Filtering, amplification, and control; the host includes filters, low-noise amplifiers, power amplifiers, duplexers, and monitoring boards; a donor antenna is used to receive downlink signals from the base station and transmit uplink signals from the mobile phone to the base station; a retransmission The service antenna is used to receive the uplink signal of the mobile phone and transmit the downlink signal of the base station; the base station is a TD-SDMA base station; the uplink signal and the downlink signal are radio frequency signals, and the frequency of the two working frequency bands is the same, and the fr...

Abstract

The related mobile communication broadband direct-transmission TD-SCDMA station comprises: a host, including a filter, a low-noise amplifier, a power amplifier, a duplexer, and a monitor plate; a donor antenna, and a re-transmission antenna, wherein the up and down RF signal has working frequency as 2010-2050MHz. This invention applies advanced technology, increases capacity -price ratio, reduces cost and maintenance, decreases system noise, and convenient to evolution.

Description

technical field [0001] The invention relates to a mobile communication broadband repeater, which belongs to the technical field of communication. Background technique [0002] The repeater is an extremely effective device used to make up for the insufficient coverage of the base station in the mobile network, expand the coverage of the base station, and fill the blind area of ​​coverage. It is widely used in various specific environments. For example, due to the shadow effect of wireless propagation, blind areas of mobile communication signals are often formed behind or in the middle of high-rise buildings; The main lobe has a large downtilt angle, so that the upper and middle parts of high-rise buildings generally cannot receive signals effectively; in addition, due to the shielding effect of buildings on electromagnetic waves, tunnels, subways, underground shopping malls, entertainment cities, parking lots, and hotels, In some closed large buildings such as office buildin...
