Method and system for location determination
A method for determining location of a premises is disclosed. The method includes measuring a signal strength of a plurality of communication signals received at the premises, obtaining data associated with a source of the signals, estimating a propagation loss for the received signal, determining a distance between a source of each of the signals and the premises based on the estimated propagation loss, and triangulating the location of the premises.
1. A set-top-box comprising:
a communication interface; and a processor, wherein
the communication interface is configured to:
receive a plurality of television signals broadcast on an over the air (OTA) interface, and
receive data associated with a source of the television signals, over a broadband connection, from a server having stored therein transmitting power levels of the source of the television signals; and
the processor is configured to:
measure a signal strength of the received plurality of television signals,
estimate a propagation loss for the received signals based on comparison of the measured signal strength to the transmitting power levels obtained from the server,
determine a distance between the source of each of the signals and a premises associated with the set-top box based on the estimated propagation loss;
triangulate a location of the premises, and
determine a direction of the source of the received signals with respect to the location of the premises.
2. The set-top box of claim 1 , wherein the received television signals are from at least three sources.
3. The set-top box of claim 1 further comprising;
a memory for storing the measured signal strength values.
4. The set-top box of claim 1 wherein the data received from the server comprises:
an identification of a transmission site for the signal source.
5. The set-top box of claim 1 , wherein the received data comprises:
a channel identification associated with the signal source.
6. The set-top box of claim 1 , wherein the received data comprises:
a location co-ordinate of the signal source.
7. The set-top box of claim 1 , wherein the communication interface is further configured to transmit the triangulated location.
