BT Wholesale has rolled its ADSL2+ WBC (Wholesale Broadband Connect) service out to some 80% of UK households and businesses, with the intention currently that the ADSL2+ service will expand to cover 90% of the UK in Spring 2013.
The increase in footprint of ADSL2+ from BT Wholesale will be welcomed by many, as even those on long lines (i.e. greater than 45dB attenuation ~3.5km) who will see little improvement to downstream speeds will probably see upstream speeds doubling, and the IP Profile system on the WBC service operates in a much more transparent manner.
Of course BT Wholesale is not alone in offering ADSL2+, TalkTalk has its ADSL2+ network reaching to around 90% of the UK now, and this network can also be accessed at the wholesale level. Sky has an ADSL2+ network similar in size to that of BT Wholesale, but Sky offers no wholesale access.
There are not many countries with three distinctly different options available at the retail level to such a large part of a country, and even fewer when you consider two of the networks are available for purchase at the wholesale level. Add to this the other smaller LLU services and the multitude of providers who use the wholesale networks and you can see how competitive the UK market is. Also we have a DOCSIS 3.0 cable network covering almost half the UK.
