    • The location of a user indoors may be specified to a degree of accuracy by use of an indoor map, generated using machine-to-machine (M2M) signaling. An indoor map is generated using a combination of signaling of a wireless router, and combining them with indoor location specific user walk-path data. The positioning data is sent to a network operator. In one embodiment, an 802.11 Router is mounted on a wall close to the ceiling with antennae tilted downwards and location address related information fed into the Router itself. The positioning map is transmitted to a cellular operator over a cellular transmission such as GSM, WCDMA LTE, etc. The signaling between smartphone and cellular RAT is reduced by mapping / converting the RSSI data with that of location specific walk-way data into a grid based format. The positioning data so generated is transferred periodically to an operator, who further transfers the data to a gateway manager. A gateway manager stores the data received from a smartphone user and provides it to authorized personnel in case of emergencies.
