Small cells including femtocells, enterprise femtocells and picocells, are essential for seamless coverage and capacity as data usage continues to increase. Small cells are necessary in the current 3G networks, but become even more crucial in the 4G/LTE networks due to the unique wide-band nature of LTE.
The improvements in mobile video capabilities and the growing popularity of data applications have created a data usage surge causing network congestion in hotspots or offices where users congregate. In addition, demand for better voice and data coverage inside buildings and homes is expanding. To address these developing market dynamics, operators are now deploying small cells to enable data to be off-loaded from the macro network seamlessly onto small localized calls within buildings.
