UK network O2 have a new product in testing and that is a Femtocell. If you do not know what one of these is then consider it a portable mast you plug into your home WiFi network to give you fill 3G signal all around your house even if you got poor or no signal in the past. Andrew has already done a great review of the unit here, so I figured it would be good to add a video overview too.
This product is currently in trial stage with O2 who are looking into rolling it out for Businesses soon and hopefully if enough people register interest then normal personal customers might be able to pick one up.
Thanks to O2 for the BoostBox..
