1. A basestation for a communications network, the communications network operating with separate downlink and uplink frequencies, wherein the basestation is operable periodically to interrupt its own transmissions to user equipment devices on said downlink frequencies in order to detect signals transmitted by neighbouring basestations on said downlink frequencies, such that the location of the basestation can be estimated based on the locations of neighbouring macrocell basestations from which said signals are detected, and such that, if the location of the basestation is changed to a non-approved location, an alarm is sent to the network.
