Femtocell

Definition
A femtocell is

"a low-­power access point, based on mobile cellular technology, providing wireless voice and broadband services to customers with a limited range within a home or in an office environment. Femtocells connect to the mobile operator's network facilities via a standard consumer broadband connection, such as DSL, cable or fiber."

Overview
"Data to and from the femtocell is carried over the Internet ­ or at least, over an Internet technology­-based network provided by an Internet Service Provider. The wireless subscriber connects to the femtocell via the normal cellular service technologies just as if he/she were using a conventional macro­cellular network connection."
