Beginning on January 23, AT&T will be sending out mailers inviting customers determined to be qualified for the program to sign up for a free Microcell. AT&T has selected the "top 7.5 percent of 3G wireless customers identified as likely to experience poor in-building coverage at home or in small offices."
The catch is that you are committed to AT&T service for a year. If you exit before then you have to either return the MicroCell or pay the Microcell's upcoming new (and raised) price of $199.99 minus $16.67 for every month that you've had it.
This verbal agreement to keep the Microcell a year has no effect on your current service plans or your eligibility for an equipment upgrade.
A femtocell like AT&T's Microcell uses your home of office's broadband to give you a better signal. To the device, it's as though it's attached to a tower, but it's attached to the femtocell instead. For places with marginal coverage, it can be the only way to get a good signal.
In a way, this is a great deal for those who get it. In another way, it's not, as it tells you AT&T considers you in their worst 7.5 percent in terms of coverage.
