A small cellular base station, typically designed for use in residential or small business environments. The benefits of these portable base stations are similar to the ones of using, for example, regular Wi-Fi access points. They allow the expansion of the corporate telephony and intranet network so it can be used by regular mobile phones.
Femtocells are the size of a regular broadband cable router. The small size offers a small area of coverage – in most cases a large-spaced room or two or three separate small rooms.
The femtocell can be easily installed by end users, while cellular towers are only installed by the carrier.
