Shrunk 3G femtocell takes less room, passes power through
UK carrier Vodafone has released a second version of its Sure Signal box. The refreshed 3G-broadcasting femtocell compacts the internals from the router-sized original into a pass-through plug design, which not only takes up as much space as a plug-in air freshener, but also allows the power socket to be completely usable by other devices.
