PROXIMITY AND TAP DETECTION USING A WIRELESS SYSTEM
First Claim
1. A method comprising:
- a wireless mobile device wirelessly receiving packets from a signal source and determining a received signal strength for each packet;
calculating, based upon information corresponding to the received signal strength for each of the packets, a current path loss value corresponding to a current distance from the wireless mobile device to the signal source; and
determining whether the current distance comprises an enabling condition for an exchange of data between the wireless mobile device and the signal source.

Abstract
A method for detecting the proximity of a signal source using wireless systems is contemplated in which a wireless mobile device wirelessly receives packets from a signal source and determines a received signal strength for each packet. The wireless mobile device may store information based upon the received signal strength for each packet, and calculate from the information stored for all the packets, a current path loss value corresponding to a current distance from the wireless mobile device to the signal source. The wireless mobile device may then determine whether the current distance is sufficient to be an enabling condition such as tap, for example, for a data transfer or a transaction between the wireless mobile device and the signal source.

11. A wireless mobile device comprising:
-
a receiver/transmitter unit configured to receive packets from a signal source; a processor coupled to the receiver/transmitter unit; and a proximity unit coupled to the processor and configured to determine a received signal strength for each packet; wherein the proximity unit is further configured to calculate, based upon information corresponding to the received signal strength for each of the packets, a current path loss value corresponding to a current distance from the wireless mobile device to the signal source; and wherein the proximity unit is further configured to determine whether the current distance comprises an enabling condition for an exchange of data between the wireless mobile device and the signal source. - View Dependent Claims (12, 13, 14, 15)
