Radiofrequency front-end module, wireless access network equipment and method for controlling same

Abstract

An embodiment of the invention provides a radiofrequency front-end module, wireless access network equipment and a method for controlling the same. The radiofrequency front-end module comprises a phase shifting and attenuating unit, a radiofrequency unit and antennas, the radiofrequency unit is respectively connected with the phase shifting and attenuating unit and the antennas, the phase shifting and attenuating unit is used for receiving control signals and radio frequency signals which are transmitted by the wireless access network equipment and realizing phase shifting or attenuating or phase shifting and attenuating for the radiofrequency signals according to the control signals, the radiofrequency unit is used for realizing radiofrequency amplification for the radiofrequency signals processed by the phase shifting and attenuating unit, and the antennas are used for transmitting the radiofrequency signals processed by the radiofrequency unit. In the technical scheme, the multiple antennas can intelligently cooperate during working.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a radio frequency front-end module, a wireless access network device and a control method thereof. Background technique [0002] At present, network service providers are vigorously promoting the digital city plan, but because the third-generation (3rd-generation, 3G) mobile communication cannot meet the needs of massive wireless network applications in the future, at present, the network service provider is advancing the wireless fidelity (Wireless Fidelity) based Wireless Local Area Networks (WLAN) based on Fidelity (WIFI) technology is an effective supplement to the third-generation (3rd-generation, 3G) mobile communication, and finally forms a wireless network service situation where WLAN and 3G complement each other. In this way, users can see two kinds of base station equipment in the future: the 3G mobile base station with large scale...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following disadvantages in the prior art: the control module, radio frequency module and antenna in the wireless access network equipment in the prior art are usually arranged on a circuit board to form an integral structure , the equipment is large in size and high in cost. Once the wireless access network equipment is set up, its performance in various aspects cannot be changed, such as the direction of the antenna Figure 1 Once determined, it cannot be changed, so that the smart antenna working mode cannot be realized
