Broadband guide
Broadband explained
Getting online has never been quicker or easier thanks to the broadband internet revolution,
but understanding how broadband works, why speed matters and what options are available to you
are key to finding the right deal. For that reason, we've compiled a broadband guide so
you can make a more informed choice.
What is broadband?
Broadband is a fast, permanent internet connection. It is often referred to as 'always
on', meaning that once you've switched on your computer you are connected. It has a
number of advantages:
- Broadband is significantly faster than a dial-up connection. This is because it uses a higher bandwidth than dial up, meaning more data can be carried at a faster speed.
- Unlike a dial-up connection a broadband connection doesn't tie up your phone line, so you are free to make and receive calls while online.
- Broadband can carry video, voice and data at the same time, meaning you can enjoy a full range of internet services. With a broadband connection you can download music, video and TV programmes, play online games and share photos etc.
How does broadband work?
There are four main types of broadband connection available: ADSL, cable, satellite and mobile. Your choice of broadband
connection will primarily depend on where you live and what’s available in your area.
ADSL broadband uses the existing telephone network. A phone socket filter, also known as
a 'microfilter', converts the phone line into two separate signals, one for telephone
and one for internet access. This means that you can make and receive telephone calls while
you are online. ADSL broadband is widely available in the UK, with coverage available to
more than 99% of the UK population.
Cable broadband transfers data using a system of fibre-optic cables laid underground; these
also support cable television and landline telephone calls. The network is currently owned
and operated by Virgin Media and over 65% of UK households currently have access to it.
Satellite broadband is an alternative to ADSL and cable broadband. It is predominantly used
in rural areas where there is no ADSL or cable broadband service available. The Internet
feed is beamed from a satellite to a dish installed at the subscriber's home; it can be
expensive to set up and the signal can be affected by weather conditions.
Mobile broadband uses the mobile phone network to connect to the internet, although you do not need
to use your mobile phone to do so! Instead, you use a data card or a USB 'dongle', which plugs
into a USB port on your computer or laptop.
Mobile broadband is ideal for those who do not want a fixed landline or who want access to broadband
on the go - perhaps when travelling to business meetings etc. It's also great for students.
Availability in your area depends on network coverage and signal strength. If the aerials have not
been upgraded to 3G (or higher) then speed and connectivity can suffer significantly.

bundles, so you can decide if they are right for you.
