I have been keeping a close eye on AT&T’s rollout of their MicroCell. The MicroCell is a femtocell which is essentially a cell tower in a box that brings cellphone reception to areas that have none. It does this by backhauling the connection over your homes broadband connection.
The team @Gizmodo just gave AT&T’s MicroCell a pretty positive review. The device works on both 850Mhz and 1900Mhz bands so it adds about 40 feet of reception with ease. The catch is that it only works with 3G phones and you have to register the phone with the base station which limits you to 10 registered numbers. That means visiting friends will not benefit unless you add them. The plus side is that since the device uses 3G it also gives you voice with data.
The huge downside is that you have to pay another $150 for a service that should work in the first place. Still its good to have options.
