WLAN intelligent antenna system and method for transmitting data

Abstract

The embodiment of the invention discloses a WLAN intelligent antenna system and a method for transmitting data. The WLAN intelligent antenna system and the method for transmitting the data are used for solving the problem of losses of uplink sensitivity of the WLAN intelligent antenna system. The WLAN intelligent antenna system comprises an antenna array and at least one WiFi intelligent antenna subsystem, the WiFi intelligent antenna subsystems comprise WiFi sublevel systems and radio frequency and antenna selection sublevel systems, the WiFi sublevel systems comprise transmitting terminals and receiving terminals, the radio frequency and antenna selection sublevel systems comprise radio frequency switches and transmit-receive switches, the radio frequency switches comprise input terminals and a plurality of paths of output terminals, and the transmit-receive switches comprise input terminals, first output terminals and second output terminals. According to transmitting channels, the transmitting terminals are connected with the input terminals of the radio frequency switches, one path of the output terminal and the first output terminal of each radio frequency switch are connected, and the other output terminals of the radio frequency switches are connected with the antenna array. According to receiving channels, the receiving terminals are connected with the second output terminals, and the input terminals of the transmit-receive switches are connected with one antenna of the antenna array.

Description

technical field [0001] The present invention relates to the technical field of Wireless Local Area Network (WLAN for short), in particular to a WLAN smart antenna system and a data transmission method. Background technique [0002] With the continuous development of computer network and wireless communication technology, WLAN has also been developed rapidly and widely used. Different from the wired network, because WLAN uses the wireless frequency band, the channel often changes drastically, which directly leads to unpredictable channel fading. In addition, the wireless channel also faces multipath interference and interference from other wireless devices in space. Wireless frequency As a valuable resource, there are strict frequency and bandwidth restrictions on WLAN. These factors directly lead to a certain gap between WLAN and traditional Ethernet in terms of performance and speed. At present, for interference-limited wireless communication systems, it is proposed to use...
