And by what I say as crowd-sourcing, I mean ask users that are willing to share
for information. What we are asking for here is several numbers: AP BSSID,
transmission power, and its geological location (latitude and longitude, as
well as height). The request is done by the device uploading a list of BSSIDs
received and its signal strength, hence BSSID never leaves our servers, and
thus privacy issue avoided.
