We saw MagicJack’s femtocell design live in their suite and came away dazzled and slightly bemused. The device itself is far from finished – it’s basically just a PCB right now – but the concept is compelling. For about the price of the MagicJack ($40 or whatever) you stream your cellphone calls through their device, bypassing the cell carriers completely. Will it work? Sure. It’s essentially like a cell booster in a package about as big as a deck of cards.

As far as I can tell carriers have little to say regarding the technology. You obviously don’t get data streaming over these devices but you do get voice. Watch the video for a bit more detail.
