Abstract: In embodiments of the present disclosure, a method is provided for managing an AP position for an access point. In the method, a magnetic distribution map is obtained for an indoor area, the magnetic distribution map representing a plurality of reference magnetic values that are collected at a plurality of reference positions in the indoor area. A plurality of magnetic measurements are received, here the plurality of magnetic measurements are respectively collected at a plurality of access point (AP) positions at which a plurality of APs are deployed within the indoor area, and the plurality of AP positions are unknown. The plurality of AP positions are mapped to a portion of the plurality of reference positions based on the plurality of magnetic measurements and the plurality of reference magnetic values. The plurality of AP positions are determined based on the portion of the plurality of reference positions. Therefore, AP positions may be determined accurately and effectively in an indoor environment.

Abstract: An antenna device may include an antenna element, a planar grounding element, a first connecting element, and a second connecting element. The antenna element includes a radiator arm, a shorting arm, and a feeder arm, the shorting arm and the feeder arm being coplanar to and extending from a first edge of the radiator arm, the feeder arm extending parallel to the shorting arm. The first connecting element connects the shorting arm of the antenna element to the planar grounding element to position the antenna element and the planar grounding element in separate parallel planes. The second connecting element extends from and perpendicular to the feeder arm of the antenna element.
