Abstract
Mobile cellular and 3G networks normally often suffer from poor penetration and reception in certain areas like indoors. This decreases the quality of voice and video communication and slows down high-speed services. 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. As a result, 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). Femto denotes a division that is mathematically represented by 10 raised to the power of -15. Deployment of femtocells in the existing macrocell networks will significantly increase because femtocells offer increase coverage, capacity and user friendly mode of operations in both home and office environments.
Applications
• Phone which will be at low cost
• New data intensive services
o Femtozone services
o Connected home services
Advantages
• increase coverage and capacity
• ‘plug and play’ device
• encryption
• can handle up to three or four simultaneous calls, from the same operator
• Can operate with normal cell phones, without any enhancements.
Disadvantages
• Reduction in call quality/ internet browsing if huge files are being downloaded from the internet simultaneously.
• Cellular only service providers are dependant on the broadband services which are beyond their control. So, trouble shooting may become an issue.
