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 comprises integrated transmitting / receiving active antennae, a radio frequency cable feed unit, power supply equipment and the like. By adoption of a space diversity active antenna system, an uplink receiving gain is improved in a space diversity receiving mode and further improved by active amplification of an uplink, so the uplink is greatly improved, the uplink and a downlink are balanced, realization of the performance of a base station is facilitated, the coverage range of the base station is expanded, and the system performance of the base station is improved. Moreover, by employing integrated design in which an active part is integrated with the antenna, the appearance of a space diversity active antenna is matched with that of the conventional passive antenna; and by employing a radio frequency cable feed technology, external connection of a power line is not required, so the antenna system is quite convenient for construction application.

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 (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 transm...
