A femtocell is a small cellular base station designed for use in residential or small business environments. It connects to the service provider’s network via broadband (such as DSL or cable) and typically supports 2 to 5 mobile phones in a residential setting. A femtocell allows service providers to extend service coverage inside of your home - especially where access would otherwise be limited or unavailable - without the need for expensive cellular towers. It also decreases backhaul costs since it routes your mobile phone traffic through the IP network.
A femtocell is sometimes referred to as "access point base station", "3G access point", "small cellular base station" and “personal 2G-3G base station".
A femtocell acts like a miniaturized cell tower in your home, creating an access point for both voice and data that provides better reception than what you might be getting from the nearby cell tower. In addition to the femtocell device (available from cell providers), you need an Internet connection and a home LAN (wired or wireless network).
After plugging the device into your network, your cell phone uses the femtocell's radio frequency to connect to your cellular network. When you leave the house, your phone will automatically switch over to communicating over the normal cell towers.
