Surrey is distinctly a county of two halves, the more urban areas are generally inside the M25 with the rural leafy commuter belt as you head further south in the county. A newsletter update from the Superfast Surrey project includes the snippet that some 310 new fibre cabinets have gone live via the project, making fibre based broadband available to another 51,000 homes and businesses in the county.
The 51,000 figure is very close to two thirds of the expected 80,000 that are set to benefit from the project at speeds of 15 Mbps or faster which is meant to finish in 2014. We know that some exchange only areas are being given access to FTTC and there is also some native FTTP in the roll-out that seems to be addressing either EO lines in some cases or clusters where FTTC would not give decent speeds.
Our own analysis of the speeds across the county which presumes every existing street cabinet gets a fibre twin and allows for ADSL2+ services and the Virgin Media footprint is below:
|Speed Estimates for Surrey with full fibre cabinet roll-out|
|2 Mbps or slower||1%|
|2 Mbps to 5 Mbps||0.5%|
|5 Mbps to 10 Mbps||0.8%|
|10 Mbps to 20 Mbps||2%|
|20 Mbps to 30 Mbps||0.9%|
|30 Mbps to 38 Mbps||10%|
|38 Mbps to 45 Mbps||8.9%|
|45 Mbps to 65 Mbps||2.2%|
|65 Mbps to 80 Mbps||3.3%|
|152 Mbps, Virgin Media cable||70%|
This is the first time we have published the full speed estimate table, this ignores any FTTP deployment or Exchange Only line work, so final figures may be better or may be worse. They would be worse if some cabinets are missed out, e.g. holes left by commercial coverage. The speeds below 24 Mbps include estimates for ADSL2+ services too so should give some idea of what level of work is required to meet the 2 Meg Universal Service Commitment. Surrey appears to have lower than average amount of Exchange Only lines, we estimate around 1% of lines in the county.
The percentage of premises estimated to get a superfast broadband service (30 Mbps or faster) is 94.7%, but if we split the county between those postcodes nominally in the London region and South East region, we get a different story of 97.1% versus 90.8%. The main reason for the difference is the variation in cable coverage i.e. 79% versus 54.9%.
For those wanting to know if they can get the new services, the Superfast Surrey website does provide clusters of postcodes when a new cabinet goes live in area.
We hope if there is enough interest to try and work on identifying where FTTP is deployed across counties under the BDUK projects and to what extent Exchange Only lines see a solution that will give superfast speeds.
