1. A method comprising:
- obtaining, in a mobile device, power information indicating a detected power of respective signals received from a plurality of transmitters;
displaying a map on a display of the mobile device;
determining the location of the mobile device based at least in part on;
locations of the plurality of transmitters, a first function of the power information and a second function of respective locations of the plurality of transmitters; and
in response to user input, placing a first indicator on the map corresponding to the determined location and a second indicator indicating a determined certainty of the determined location.

2. A method comprising:
-
obtaining, in a mobile device, power information indicating a detected power of respective signals received from a plurality of transmitters; determining a location of the mobile device based at least in part on;
locations of the plurality of transmitters, a first function of the power information and a second function of respective locations of the plurality of transmitters, wherein the location is determined based at least in part on a formula that depends on a log10 of the detected power and a log10 of a modeled transmitter power; andin response to user input, placing, on a display of the mobile device a first indicator corresponding to the determined location and a second indicator indicating a determined certainty of the determined location.
