[Qt-interest] energy cost of wi-fi scan?

[Jason H]

Tasker for Android does this. 
You can set the coordinates with a pin on the map (or "here") and then set the radius. If you are in an area of many mode points, you can tell it to use GPS, but if there are no other points near by then just use the radio estimation.
 
I've not used that part of mobility yet, but you should be able to pull a few towers and signals "for free" from the normal phone operation.

Thanks, I'm trying QGeoPositionInfoSource now, it works nice, I'll disable 
satellite source.
