1. On a first device, a method for estimating a path-loss between the first device and a second device, the method comprising:
- determining a user context indicator associated with the first device;
updating at least one path-loss parameter of a plurality of path-loss parameters for the first device based on the user context indicator;
receiving at least one wireless signal from the second device;
estimating the path-loss between the first device and the second device based on the plurality of path-loss parameters and the at least one wireless signal,the plurality of path-loss parameters comprising a path-loss exponent, andthe estimating the path-loss comprising estimating the path-loss repeatedly using the path-loss exponent; and
performing a proximity-triggered function based on the estimated path-loss and an alert threshold.

Abstract
A method on a first device for estimating path-loss between the first device and a second device is described. A user context indicator associated with the first device is determined. At least one path-loss parameter of a plurality of path-loss parameters for the first device is updated based on the user context indicator. At least one wireless signal is received from the second device. The path-loss between the first device and the second device is estimated based on the plurality of path-loss parameters and the at least one wireless signal.
