US 12,716,984 B2 · Anchor location calibration

Abstract

In an example implementation according to aspects of the present disclosure, a wireless anchor node comprises a wireless communication interface and a processor communicatively coupled to the wireless communication interface. The processor receives a wireless signal from a source access node. The location of the source access node is verified. The processor determines a distance measurement between the wireless anchor node and the source access node based on the wireless signal and transfers the distance measurement between the wireless anchor node and the source access node to a target access node over an intermediate anchor node. In response, the processor receives a location error from the target access node over the intermediate anchor node. The location of the target access node is verified. The processor calibrates the distance measurement between the wireless anchor node and the source access node based on the location error.
