Method, System and/or Device for Adjusting Expected Received Signal Strength Signature Values

An apparatus comprising:

• a transceiver to transmit and receive signals over a wireless communication link;
• and
• one or more processors to:
• obtain a measurement of travel time of a first signal transmitted between the transceiver and a remote transmitter;
• obtain a measurement of a signal strength of a second signal transmitted by said remote transmitter and received at a receiver;
• and
• combine the measurement of travel time with the signal strength to adjust one or more expected signal strength signature values for application to subsequent signals acquired from said remote transmitter.

An article comprising:

• a non-transitory storage medium comprising machine-readable instructions stored thereon which are executable by a special purpose computing apparatus to:
• obtain a measurement of travel time of a first signal transmitted between a mobile device and a transmitter;
• obtain a measurement of a signal strength of a second signal transmitted by said transmitter and received at said mobile device;
• and
• combine the measurement of travel time with the measurement of the signal strength to adjust one or more expected signal strength signature values for application to subsequent signals acquired from said transmitter.

An apparatus comprising:

• means for obtaining a measurement of travel time of a first signal transmitted between a computing device and a transmitter;
• means for obtaining a measurement of a signal strength of a second signal transmitted by said transmitter and received at a receiver;
• and
• means for combining the measurement of travel time with the signal strength to adjust one or more expected signal strength signature values for application to subsequent signals acquired from said transmitter.
