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

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

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

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

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.
