  6. 6. A Femtocell DefinitionA small cellular base station, designed for use in residential.Connects to the service provider’s network via broadband.Support 2 to 5 mobile.Allows service providers to extend service coverage indoors.Incorporates the functionality of a typical base station butextends it to allow a simpler, self contained deployment.The concept is applicable to all wireless standards, includingUMTS, GSM, CDMA-2000, TD-SCDMA and WiMAX solutions.
