Technologies are generally described for providing localized location information associated with users for emergency service purposes. A user device with wireless communication capabilities employing one or more technologies may initiate an emergency communication in one or more modalities upon triggering by the user or by an external trigger signal and activate beacon modes for one or more of the available wireless technologies transmitting periodic signals, one or more attributes of which such as period, modulation rate, frequency may be optimized. The beacon signal may also include an identifier associated with the user enabling emergency personnel to locate the user employing line-triangulation. |
