Femtocell

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.

These are low powered wireless access point that operate in licensed spectrum to connect standard mobile devices to a mobile operator’s network using residential DSL or cable broadband connections.

Femtocell Working -

A femtocell is typically the size of a residential gateway or smaller, and connects to the user's broadband line. Once plugged in, the femtocell connects to the MNO's mobile network, and provides extra coverage in a range of typically 30 to 50 meters. Then user declare which mobile phone numbers are allowed to connect the femtocell, usually via a web interface provided by the MNO.Once the mobile phone come under the coverage of the femtocell ,they switch over from the macrocell to the femtocell automatically .All communications will then automatically go through the femtocell. When the user leaves the femtocell coverage area, his phone hands over seamlessly to the macro network.

Benefit to users -

• Excellent network coverage when there is no existing coverage or low coverage.
• For enterprise users having femtos instead of DECT or WiFi dual mode phones enable them to have a single phone, so a single contact list etc.
• Provide higher capacity if user uses data services through his mobile phone.
• A Femtocell can also give lower call charges while the caller calling from home, using the Femtocell as it directly connects to the core network through the internet.
• Femtocell units can handle up to three or four simultaneous calls, from the same operator, depending on the model. They can operate with normal cell phones, without any enhancements.
• Femtocell units can help related cellular services like 3G by offering a better speed and data rate when inside buildings, where the coverage and data rate is generally lesser than outside.
