Technology : Wibree

Some old news but I came across it for the first time,

"Wibree is a new interoperable radio technology for small devices. It can be built into products such as watches, wireless keyboards, gaming and sports sensors, which can then connect to host devices such as mobile phones and personal computers. It is essential the missing link between small devices and mobile devices/personal computers." link

"Nokia introduces Wibree technology as open industry initiative" link
