Small cells’ is an umbrella term for operator-controlled, low-powered radio access nodes, including those that operate in licensed spectrum and unlicensed carrier-grade Wi-Fi. Small cells typically have a range from 10 meters to several hundred meters.
Types of small cells include femtocells, picocells and microcells – broadly increasing in size from femtocells (the smallest) to microcells (the largest). Any or all of these small cells can be based on ‘femtocell technology’ – i.e. the collection of standards, software, open interfaces, chips and know-how that have powered the growth of femtocells.Indoor small cells provide the lowest Total Cost of Ownership for providing coverage and capacity in indoor hot spots in enterprises and public buildings.
