Let's take a second to LEARN before you go chasing the Black Helicopters.
Skyhook and how it works.
In case you weren't aware of it, those airwaves your Router uses, are PUBLIC. It's not a case of someone hacking and monitoring you - it's a case of using your Wifi to help refine and make GPS locations easy, fast and accurate for everyone else.
And yup, this included Police and Emergency Vehicles too.
Good grief, you need the lesson. Google is not only recording Wifi networks but also the devices MAC address that are connected to them. There is no public need to know your wifi enabled printer or computer MAC address for any other reason than to locate a particular device to a particular geographic location.
Does this mean civilians can not track and locate police cars for purposes of avoiding speeding traps?
