Vodafone Sure Signal now plugs directly into the wall, doles out more 3G at once

Femtocells are rarely subtle devices, including Vodafone's earlier Sure Signal models. That's what makes a newly revamped version of the Sure Signal so noteworthy -- it's very nearly unintrusive. The new edition plugs directly into a wall outlet and doesn't occupy more space than a night light, letting it dish out 3G in low-reception areas without becoming a conspicuous part of the landscape. It's also a better pick for offices, or just crowded homes, now that it can handle as many as eight 3G connections at the same time. UK locals who face the unenviable dual problems of cellular dead zones and tight spaces can solve both at once by spending £100 ($161) today.
