- 22. www.cswbroadband.org.uk First: What Can We Map? • PAC Report Summary – BT is preventing local authorities from providing proper information on the areas it will and will not cover with superfast broadband. (page 3) – Details about speed and coverage are treated as commercially confidential in each local project. – BT …has no objection to publishing this data for finalised contracts. – http://www.publications.parliament.uk/pa/cm201314/cmselect/cmpubacc/474/474.pdf
- 23. www.cswbroadband.org.uk What Should We Map? • We know the targeted Cabinets • The SCT limits the Postcodes upgraded • The Physics limits the distance • Publicly available – BT’s best guess of – Address to Cabinet mapping – Products and speeds • And the BT API Access is available on request

Editor's Notes
- Here’s a cabinet serving only 18 premises in the intervention Area!
- How many disappointed people if we just highlight the postcodes? Highlighted rows are served by multiple cabinets: 1,2,3 and 25
- How effective is a threshold? Must be premise based to communicate effectively
- Overspill can be avoided by “good choice” of Postcodes to include but this leaves some people without coverage.
- In this example, there are 18 in one block so surely this must be simple for the alternative provider to fix – but they did not declare it as covered in the OMR so it must be State Aid White.
- The premise checker confirms this, two sides of the same street. In the OMR we gave them an opportunity to undertake to cover these but were unwilling to commit.
- The premise checker says it all
- Some areas have small gape across multiple cabinets, e.g. 35 Premises
