1. A system for tracking location, comprising:
- a plurality of transmitter tags disposed to cover an area where the location tracking is to be carried out, wherein each transmitter tag is configured to radio broadcast a unique identifier by using a Bluetooth radio communication technology;
at least one mobile personal radio communication device configured to scan for Bluetooth radio broadcasts, to detect at least one unique identifier broadcasted by at least one transmitter tag close to the location of the personal radio communication device, and to transmit a message comprising at least one of the detected unique identifiers to a server over a communication connection established between the personal radio communication device and the server; and
the server configured to receive messages from the at least one personal radio communication device, each message comprising at least one unique identifier of at least one transmitter tag, to link a preconfigured location of a given transmitter tag, determined from the received message, with the personal radio communication device from which the message was received so as to determine the location of the personal radio communication device, and to store an identifier of the personal radio communication device as linked to the determined location of the personal radio communication device,wherein a first personal radio communication device is configured to send an alarm signal to the server, and wherein the server is further configured to receive the alarm signal and to convey the alarm signal to a nearest second mobile personal radio communication device of the location tracking system,wherein the server comprises a memory storing information indicating the closest neighboring transmitter tags for any transmitter tag in an order of the shortest distance via access routes through which a human being can move, and wherein the server is configured to determine the nearest other mobile personal radio communication device to be a personal radio communication device having the shortest distance via access routes through which a human being can move to the first personal radio communication device.

Abstract
This document presents a location tracking system. Transmitter tags are disposed throughout the area where the location tracking is carried out. The transmitter tags are configured to transmit their unique identifiers. A personal radio communication device being tracked detects a unique identifier received from a transmitter tag and transmits the detected unique identifier to a server. The server links a known physical location associated with the unique identifier to an identifier of the personal radio communication device so as to carry out location tracking.
