Mobile terminal, and locating method and device
First Claim
1. A mobile terminal, comprising:
- a first antenna, configured to transmit a first signal to an anchor node, wherein the first signal is used by the anchor node to detect the signal strength of the first antenna;
a second antenna, arranged with the first antenna at a preset angle and configured to transmit a second signal to the anchor node, wherein the second signal is used by the anchor node to detect the signal strength of the second antenna, there is an overlap between the coverage of the first antenna and that of the second antenna due to the preset angle, and the signal strength of the first antenna and the signal strength of the second antenna are used for determining the location of the mobile terminal.

Abstract
A mobile terminal, and a locating method and device are provided, wherein the mobile terminal includes a first antenna, configured to transmit a first signal to an anchor node, wherein the first signal is used by the anchor node to detect the signal strength of the first antenna; a second antenna, arranged with the first antenna according to a preset angle and configured to transmit a second signal to the anchor node, wherein the second signal is used by the anchor node to detect the signal strength of the second antenna. The preset angle enables the coverage of the first antenna and the second antenna to be overlapped to some extent. The signal strength of the first antenna and the signal strength of the second antenna are used for determining a location of the mobile terminal.
