High Quality Content by WIKIPEDIA articles! A picocell is wireless communication system typically covering a small area, such as in-building (offices, shopping malls, train stations, etc.), or more recently in-aircraft. A picocell is analogous to a WiFi access point. In cellular wireless networks, such as GSM, the picocell base station is typically a low cost, small (typically the size of a sheet of A4 paper and about 2-3 cm thick), reasonably simple unit that connects to a Base Station Controller (BSC). Multiple picocell 'heads' connect to each BSC: the BSC performs radio resource management and hand-over functions, and aggregates data to be passed to the Mobile Switching Centre (MSC) and/or the GPRS Support Node (GSN).
