Embodiment Construction

[0024] The wireless device provided by this application can be used to locate a terminal to be located. in:

[0025] The wireless device is a device that is deployed in the positioning area, has a known position, and has the function of wireless transmission and reception. One or more wireless devices may be deployed in one positioning area, and each wireless device is provided with an antenna array. Different wireless devices may use the same antenna array or different antenna arrays. The wireless device may be an access point (English: access point, AP) with an antenna array, a base station, a personal computer or a mobile terminal, and the like.

[0026] The terminal to be positioned is a device that is deployed in the positioning area, its location is unknown, and it has the function of wireless transmission and reception. One or more wireless transceivers can be set on the terminal to be positioned. Terminals to be located may include mobile phones, wearable devices, ...

Abstract

Provided are a wireless device and a positioning method, which relate to the field of positioning technology, and can save radio-frequency (RF) circuits, with a simple structure. The wireless device comprises: an RF circuit set, a first antenna set, a second antenna set and a switch circuit, the antennas in the first antenna set being in the first straight line, the antennas in the second antenna set being in the second straight line, the first straight line being not parallel with the second straight line, the number of the RF circuits in the RF circuit set being smaller than the sum of the number of the antennas in the first antenna set and the number of the antennas in the second antenna set; the switch circuit being used for connecting the RF circuits in a RF circuit set and the antennas in the first antenna set within a first time duration, each antenna in the first antenna set being connected to one RF circuit in the RF circuit set; the switch circuit being used for connecting the RF circuits in a RF circuit set and the antennas in the second antenna set within a second time duration, each antenna in the second antenna set being connected to one RF circuit in the RF circuit set.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a wireless device and a positioning method. Background technique [0002] The basic principle of positioning technology based on signal angle of arrival (English: angle of arrival, AOA) is: the wireless device obtains the azimuth angle between the terminal to be positioned and the line where the multiple antennas are located according to the phase difference of the signals collected by the multiple antennas. The position of the terminal to be located is determined according to the azimuth angle between the terminal to be located and different straight lines. [0003] In order to improve positioning accuracy, a radio frequency module used for AOA positioning in traditional wireless devices has a large number of radio frequency channels and a complex structure. Contents of the invention [0004] The present application provides a wireless device and a positioning met...
