AT&T 3G MicroCell acts like a mini cellular tower in your home or small business environment. It connects to AT&T's network via your existing broadband Internet service (such as DSL or cable) and is designed to support up to four simultaneous users in a home or small business setting. With AT&T 3G MicroCell, you receive improved cellular signal performance for both voice calls and cellular data applications like picture messaging and surfing the Web. - ATT.comhttp://www.wireless.att.com/learn/why/3gmicrocell/

It'll cover up to 5,000 square feet, allow up to four simultaneous voice or data connections (locked down so that your neighbors can't pilfer the signal), and most interestingly, will only work with 3G phones. We've heard that femtocells are more difficult to manage in a 2G GSM environment than in CDMA and WCDMA -- hence the 3G requirement -- but the cells offered by Sprint and Samsung only offer 2G coverage, so AT&T's arguably got an advantage here. - Engadgethttp://www.engadget.com/2009/01/25/details-on-atandts-3g-microcell-everything-but-the-date-and-pric/

AT&T has finally unleashed its new femtocell in a public market trial in Charlotte, N.C. Dubbed the 3G MicroCell, the AT&T femtocell is designed to boost both the voice and data signal in your home by using your home broadband network. This is similar to how Verizon's and Sprint's femtocells work, though neither of them handles 3G/EV-DO. (Instead of femtocells, T-Mobile has gone the UMA route with T-Mobile HotSpot @ Home, which requires UMA-enabled phones that can use Wi-Fi to make calls). - Cnet.comhttp://www.cnet.com/8301-17918_1-10358045-85.html
