Problems solved by technology

For the uplink signal transmitted by the mobile phone received by the base station antenna, the feeder loss means an increase in the noise figure, which will further reduce the receiving sensitivity of the base station and reduce the uplink coverage

Embodiment approach

[0033] As an implementation manner, the uplink active amplification control circuit 7 includes:

[0034] An amplification module for amplifying the uplink signal, specifically, software control can be realized for the gain of the signal;

[0035] A monitoring module connected with the power supply device 3 to monitor the uplink.

[0036] In this way, the uplink active amplification control circuit 7 can monitor the uplink, and generate an alarm when applause occurs in the uplink.

[0037] As an implementation manner, the uplink active amplification control circuit 7 may further include:

[0038] Bypass control module connected to monitoring module to control automatic bypass when uplink alarms.

[0039] In this way, when an alarm occurs on the uplink, the system will automatically bypass to keep the uplink unobstructed.

[0040] As an implementation manner, the power supply device 3 may include:

[0041] A receiving module for receiving monitoring alarm information sent by...

Abstract

The embodiment of the invention discloses an antenna system, which includes an integrated transceiver active antenna, a radio frequency cable feed unit, power supply equipment and the like. The space diversity active antenna system uses space diversity reception to increase the uplink reception gain, coupled with uplink active amplification, further improves the uplink reception, thereby greatly improving the uplink and making the uplink and downlink balance, It is beneficial to give full play to the performance of the base station, improve the coverage of the base station, and improve the performance of the base station system. Moreover, the space-diversity active antenna adopts an integrated design, integrating the active part into the antenna, which is consistent with the traditional passive antenna in appearance, and adopts the technology of RF cable feeding without external power lines, so it is suitable for construction applications. It's quite convenient.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an antenna system. Background technique [0002] Mobile communication has played an increasingly important role in people's daily life. By the end of 2009, the number of mobile communication users in my country has exceeded 700 million, and this number is still increasing at a high speed. Since the issuance of 3G licenses in China in 2009, operators have started a new round of large-scale construction of base stations; overseas, with the success of Long Term Evolution (LTE) pilots, global operators have begun to invest in 4G construction. [0003] For the entire base station system, the uplink and downlink are actually unbalanced. First, because the base station and the mobile phone have different transmission powers, the base station’s transmission power is often relatively large, and the coverage area is relatively wide, while the mobile phone’s transmission power is relat...
