3 Using your Femtocell
3.1 How it works
Traditionally your mobile phone provides service using a long‐distance radio
connection with a mobile phone network.
The Femtocell is a mobile access point that seamlessly replaces this service when
you are indoors. It uses your broadband internet connection to communicate with
the mobile network, and because it provides coverage indoors it is very low power ‐
similar or lower than the power used by a regular cordless home phone, Wi‐Fi router
or even your mobile phone.
The result is outstanding 3G coverage including dependable, high‐speed data
services like music download and video. The 3G mobile network detects when you
are moving between the outdoor network and your indoor Femtocell coverage area
and automatically shifts between the two without any intervention required.
3.2 Broadband connection
Increases in broadband data speeds over telephone lines and cable TV now make it a
viable means to transport other forms of data as well as the Internet and music
downloads.
The Femtocell plugs into your broadband interface and accesses your Mobile
Operator's network in a secure manner just like the mobile equipment you see
outside. This ensures that it functions in exactly the same way, offering you all the
latest 3G services. As with any mobile equipment, the Femtocell automatically
connects to the network without you having to press any buttons to communicate
with it via a computer.
Since the Femtocell shares your broadband interface with your PC Internet
connection, it has to be able to support both simultaneously. If you frequently
download large amounts of data such as music from the Internet, we recommend
that your broadband speed is better than 1Mbps in the downlink direction and 512
kbps in the uplink direction. Additionally if your broadband router is capable of
supporting Class of Service data prioritisation then you can configure it to prioritise
your Femtocell data and provide a better quality of service to your mobile device.
3.3 Indicator Lights
The indicator light tells you what the Femtocell is doing and whether or not it is
experiencing any problems. It can be either green to show it is operating properly, or
red to highlight a problem. The Femtocell can take up to 10 minutes to configure
itself after switching on for the first time. During this period, it carries out a number
