Abstract
A method and apparatus, a gateway, a terminal, an adjustment system, and a storage medium are provided. The method may be applied to a gateway. The gateway may determine position information of at least one terminal through at least three ultra-wide band modules. The at least one terminal may be within a network coverage range of a gateway. The gateway may include the at least three ultra-wide band modules. The gateway may adjust a lobe direction of an antenna based on the position information of the at least one terminal to achieve shaped beam coverage for each terminal.

A method for antenna adjustment, comprising:
- determining, by a gateway comprising at least three ultra-wide band modules, position information of at least one terminal through the at least three ultra-wide band modules, wherein the at least one terminal is within a network coverage range of the gateway;
- and
- adjusting, by the gateway, a lobe direction of an antenna based on the position information of the at least one terminal to achieve shaped beam coverage for each terminal,
- wherein determining the position information of the at least one terminal through the at least three ultra-wide band modules comprises:
- determining, by the gateway, at least two hyperbolic curves through the at least three ultra-wide band modules;
- and
- taking, by the gateway, intersection position information of an intersection of the at least two hyperbolic curves as the position information of the terminal,
- wherein determining the at least two hyperbolic curves through the at least three ultra-wide band modules comprises:
- determining a first distance difference between a distance from a first ultra-wide band module to the terminal and a distance from a second ultra-wide band module to the terminal, wherein the at least three ultra-wide band modules comprise the first ultra-wide band module, the second ultra-wide band module, and a third ultra-wide band module, wherein the at least two hyperbolic curves comprise a first hyperbolic curve and a second hyperbolic curve;
- determining a second distance difference between the distance from the second ultra-wide band module to the terminal and a distance from the third ultra-wide band module to the terminal;
- forming the first hyperbolic curve based on that a distance difference between the distance to the first ultra-wide band module and the distance to the second ultra-wide band module is a trajectory of the first distance difference;
- and
- forming the second hyperbolic curve based on that a distance difference between the distance to the second ultra-wide band module and the distance to the third ultra-wide band module is a trajectory of the second distance difference.
