Abstract: A User Equipment (UE) for use in a wireless network including a first radio access network supporting a first radio access technology and a server system including a stored database of wireless nodes, the stored database identifying fixed wireless nodes that are geographically dispersed and that broadcast a signal including identification data. The UE includes a transceiver for communicating using the first radio access technology, a position determination unit for determining a geographical location, and a controller for accessing data derived from the stored database, monitoring broadcast signals received using the first radio access technology, upon receipt of an update request from the server system, deriving identification data and signal strength data of the fixed wireless nodes from the received broadcast signals, generating update data from the identification data, signal strength data, and geographical location data relating to the UE, and transmitting the update data to the server system.
