A guide to the major broadband providers in the UK

Some Technical notes

BROADBAND - A transmission facility having a bandwidth sufficient to carry multiple voice, video or data channels simultaneously. Each channel occupies (is modulated to) a different frequency bandwidth on the transmission medium and is demodulated to its original frequency at the receiving end. Channels are separated by ìguardbandsî (empty spaces) to ensure that each channel wonít interfere with its neighboring channels. This technique is used to provide 50 CATV channels on one coaxial cable.

How is broadband delivered?

Broadband services can be delivered in different ways – over an ordinary telephone line or private network, via a cable connection or across mobile and wireless networks. BT offers ADSL broadband services over a customer’s existing BT telephone line, separating voice and data signals so you can continue to make calls when you are on the internet.
