Introduction

A Femtocell is a small device that is used to improve wireless coverage over a small area, mostly indoor. It is a small cellular base station, also called a wireless access point that connects to a broadband Internet connection and broadcasts it into radio waves in its area of coverage.mobile handsets can handle phone calls through the femtocell, via the broadband Internet connection. The name femtocell has the prefix 'femto', meaning a very small cell (area of network coverage).

History On Femtocell

The first interest in femtocells started around 2002 when a group of engineers at Motorola were investigating possible new applications and methodologies that could be used with mobile communications.

A couple of years later in 2004, the idea was beginning to gain some momentum and a variety of companies were looking into the idea.

With the idea gaining momentum, and many more companies investigating femto cell technology, the Femto Forum was set up in July 2007. Its aim was to promote the wide-scale adoption of femtocells.

Why Femtocell ?

Technical motivation Reduced separation distance between transmitter and receiver Interference is isolated by building structure Limited number of users

Business motivation Operators expand network capacity and coverage without much investments on

infrastructure. Subscribers get better radio service at low price
