s, which are now mostly digital optical fibre cables. There are many satellite links too, but these now provide a relatively small part of the international bandwidth.

Broadcast Transmission

Most broadcasting organisations, BBC and commercial, lease transmission facilities from one or more of the transmission companies. The main exception is the smaller local radio stations, some of which find it more cost-effective to provide their own.

Fixed Phone Lines

BT is still the main provider of fixed telephones lines, both POTS and ISDN, and it has a universal service obligation, although companies can now contract Openreach to install a phoneline on their behalf, rather than telling the customer to get BT to install it, then transfer over.

Virgin Media is the second biggest player in the residential telephone line market.

Other companies provide fixed telephone lines too, but mainly to large companies in the major cities.

There are many other providers who sell fixed telephone services carried over BT lines. They have no network infrastructure of their own.

Third Generation Networks

The four 2G companies all won 3G licences in a competitive auction, as did a new entrant known as 3. They have now rolled out their networks. 3 does not operate a 2G network, but has an agreement with Orange whereby customers who lose a 3G signal roam with Orange. They previously had an agreement with O2 to provide the same service.

The 3rd generation stems from technological improvements and is in essence an improvement of the available bandwidth, enabling new services to be provided to customers.

Such services include streaming of live radio or video, video calls and live TV.

Orange have biggest 3G coverage, currently standing at 93.2% (Q3 2009). However Vodafone and Orange have a good amount of coverage. T-Mobile has fairly good coverage as does O2 but generally only in major cities and less so in smaller towns, however T-Mobile and 3 have recently struck a deal whereby they can use each others 3G coverage but 3 customers cannot use T-Mobile 2G coverage. Three also have an additional agreement with Orange until 2010 in which Orange 2G coverage is available to three subscribers where no 3G signal exists. It is unknown whether this agreement will continue if the merger between Orange and T-Mobile is approved.
