The surest way to increase the system capacity
of a wireless link is by getting the transmitter
and receiver closer to each other, which creates
the dual benefits of higher-quality links and
more spatial reuse. In a network with nomadic
users, this inevitably involves deploying more
infrastructure, typically in the form of microcells,
hot spots, distributed antennas, or relays. A less
expensive alternative is the recent concept of
femtocells — also called home base stations —
which are data access points installed by home
users to get better indoor voice and data coverage.
In this article we overview the technical and
business arguments for femtocells and describe
the state of the art on each front. We also
describe the technical challenges facing femtocell
networks and give some preliminary ideas
for how to overcome them.
