Wi-Fi Bracelet Tracks Grandma Or That Lying Whore Of A Husband

Ekahau's T301W Wi-Fi Bracelet can pinpoint the exact location of anyone wearing it, without the use of GPS. But there's a catch.

While mobile phones often use Wi-Fi to triangulate a person's position in the world, the T301W only works on preconfigured Wi-Fi networks that are coupled with additional beacons. In other words, you sort of build your own Wi-Fi triangulation network in a smaller area.

But the idea is still pretty handy. The $US60 waterproof wristband operates up to a month between recharges, and it would allow hospitals to keep tabs on troubled patients, family members to locate one another on cruise ships and, when coupled with a remote detonation device, could make anyone capable of running their own forced labour camp.
