What is Femtocell
A femtocell is a small cellular base station designed for use in
residential or small business environments. It connects to the service
provider’s network via broadband (such as DSL or cable) and typically
supports 2 to 5 mobile phones in a residential setting. A femtocell
allows service providers to extend service coverage inside of your
home - especially where access would otherwise be limited or
unavailable - without the need for expensive cellular towers. It also
decreases backhaul costs since it routes your mobile phone traffic
through the IP network.
A femtocell is sometimes referred to as a “home base station”,
“access point base station”, “3G access point”, “small cellular base
station” and “personal 2G-3G base station”.

What is THE FMC Concept?
FMC: Fixed Mobile Convergence
converge
verb [I]
1. If lines, roads or paths converge, they move
towards the same point where they join or meet:
2 If ideas and opinions converge, they gradually
become similar.
3 to come from other places to meet in a
particular place:
convergence noun [C or U]

History of FemtoCell
According to Wikipedia
In 2002, a group of engineers at Motorola in Swindon, England,
started a skunkworks team, called the "AFG", to develop new
technologies. Some of their major achievements included the
world's smallest full-power UMTS base station, one of the first
demonstrations of television to mobile, and the invention and
development of the access point base station (ie. Femtocell). The
original design was intended to provide a direct equivalent to a
WiFi access point, but for mobile cellular (UMTS, CDMA-2000 or
WiMAX). The unit contained all the core network elements and did
not require a cellular core network, requiring only a data
connection to the Internet or WiFi core network.

How fast can it go?
-2.5 G
-The femtocell will be 2G GSM technology, supporting data services
through GPRS and EDGE which typically offer up to 384kbit/s.
-3G UMTS HSPA
-Femtocells add network capacity and make it possible to deliver 7.2
Mbps and 14.4 Mbps HSDPA data rates to consumers in indoor
environments.
-Evolved HSPA provides HSPA data rates up to 42 Mbit/s on the
downlink and 22 Mbit/s on the uplink with MIMO technologies and
higher order modulation.

How fast can it go?
WiMAX 802.16e 3.5GHz 70Mbit/s
WiMAX Quoted speeds only achievable at very short ranges,
more practically 10 Mbit/s at 10 km.
LTE Downlink 326.4 Mbit/s Uplink 86.4 Mbit/s
LTE-Advanced update to offer over 1 Gbit/s speeds.

Final Thoughts
These technologies are brothers and
sisters.
The Question is How FemtoCells will
evolve along side 4G technologies such
as WiMAX LTE.
They will definitely be in our lives.
