Abstract
This document describes a solution for sensing a location by using a wireless network. According to an aspect, a method for an access node of the wireless network comprises: receiving, by the access node from a wireless device at a location, a channel measurement signal; determining, by the access node, precoding coefficients for the location based on the channel measurement signal; storing, by the access node, the precoding coefficients as linked to the location; and utilizing, by the access node, the preceding coefficients to acquire information on the location.
