A system enabling mobile wireless users to obtain information on other proximate users both fixed and wireless. Said information is gathered from a central database that stores user profiles and real-time locations of system users. Mobile users can request information on nearby users by submitting a request from a mobile telephone or similar communications endpoint to the central database. The request is accompanied by the user's location, obtained from GPS (Global Positioning System) or other technology, or from user input. The server searches the profile database for nearby users based on requester's location, locations of other users of the system and optional parameters specified in the request. Search results are returned to the requester. The system facilitates communication between requester and owner(s) of profiles returned by system.
