Own communication equipment locates a source of wireless transmissions, the own equipment including a serving base station (BS). The serving BS receives, from remote sensors including at least one user equipment (UE), sensing information from which transmitter location information (“location information”) can be determined. The location information is oriented in a serving BS coordinate system. The location information can comprise white space sensing information from which a direction of a transmitter relative to a position of the UE can be determined, and pilot signal sensing information from which respective directions of one or more BSs relative to the position of the UE can be determined. The BS transforms the white space and pilot signal sensing information into the location information. Geographical safety margins are determined from the location information, and BS transmissions are adjusted to limit transmitting signals beyond the geographical safety margin area.
