Femtocells [Guest Editorial]

Femtocells are destined to transform the way mobile operators build their cellular networks and grow their coverage and capacity. Femtocells are small base stations operating in the licensed cellular bands. They are so small and inexpensive, and transmit at such low power, that they are meant to be placed in individual homes and backhauled onto the operator¿s network via conventional digital subscriber line (DSL) or cable broadband access (or, when available, fiber).
