Getting it right first time round. Better planning and mapping for digital networks, cutting costs and raising demand. This case study from the Coventry, Solihull and Warwickshire partnership shows how local authorities get vastly better value from broadband investment by challenging the assumptions.

About Coventry, Solihull and Warwick (CSW) Broadband
These areas make up the CSW Region:
• Coventry City
• North Warwickshire Borough
• Nuneaton and Bedworth Borough
• Rugby Borough
• Solihull Metropolitan Borough
• Stratford-on-Avon District
• Warwick District
Needed to deliver the Government’s 2015
targets, that everyone should be able to access
broadband at speeds of at least 2Mbps and
that superfast broadband should be available
to 90% of premises in each authority.

How has the data and mapping analysis helped CSW Broadband?
Some examples
 “As a result of our pre-procurement discussions with the broadband providers we have
received updated Open Market Review data that shows an extra 44,690 properties
now being brought into the commercial roll-out, meaning that the money within the
CSW Broadband project will go that much further.”
 “Thanks to the information provided by our local communities through their Local
Broadband Champions and the surveys on our website, our team has been in
discussions with BT about areas that have been omitted from their commercial roll-out
plans.”
 “At both Warwick Gates and Coton Park we were able to show that there were
sufficient potential subscribers for superfast broadband services to make a clear
business case for BT to invest in these areas.”
 “Through the data that we have collected over the past couple of years we have
good knowledge of our area and so were able to apply to BDUK for additional funding.
This means that with match funding an additional £750,000 has been brought to the
project, which has yet to be allocated to the rollout programme.”

State Aid Categories
White, Grey and Black classifications
From Open Market Review data:
White - no broadband infrastructure
exists or is unlikely to be developed in
the near term – intervention areas
Grey - only one broadband network
operator is present
Black - at least two or more
broadband network providers are
present

How did Synchronoss help?
Geospatial network analysis and processing
 CSW wanted to get a more definitive answers to the following questions:
− How do FTTP and FTTC solutions compare in their region
− How many premises are suitable for intervention
− How accurate is the 3rd party data provided, e.g. cabinet locations
 For the „White area‟ premises:
− Which were likely to achieve Superfast Broadband speeds after intervention
− Which premises would be the cheapest to connect via FTTP

Demographics of Demand
Building block for additional analysis
 AddressBase© Premium data
− Rich, complex & comprehensive address dataset
− Part of the PSMA suite of data
 Defining an „address‟
− Is the delivery point the same as the geographical address?
− Streets can be vertical… hard to visualise.
 Demand registration, Benefit Index
− Is a tennis court, monument, farm outbuilding or school generator
building a candidate for broadband?
 Data stewardship
− Ownership lies between OS, BDUK, LA, etc.

Joining the dots…
Finding the common reference
 Address Base
− Full and standardised address record and GPS coordinates
− Contains Residential & Business categories
− Contains Multiple Occupancy codes
 BT
− Provide Copper Cabinet to Postcode lists
 Commercial providers
− Provide postcodes/cabinets planned for future SFB deployment
 Link them all together via Postcode to provide
− Full premise list for „White‟, Grey and Black areas
− Classification for each address as Business demand, Residential demand or No demand
− Relationship between each premise and feeding cabinet

Local Broadband plan
Extract from the CSW Local Broadband Plan*
“Given their significant presence, understanding the likely footprint of BT‟s
rollout of superfast broadband is key to ensuring that our interventions are
targeted on the areas of greatest need”
“This [BT] data will underpin the advice and guidance we provide to
ensure community efforts and activities are as fully informed as possible”

Plan for success
Why would a LA want to plan a network?
Understand the likely costs for each
supplier proposal
− or at least the quantities of work and
materials required
Share proposed solutions and engage
further with the community
Validate supplier assumptions or 3rd
party data during tender process
Demonstrate value for money
Sometimes the „law of averages‟ just
isn‟t good enough…

25. 25SYNCHRONOSS PROPRIETARY
FTTC Network Modelling
Overview of data processing
 BT/local champion provided X,Y coordinates for Exchange and
Cabinet
− Easy to find straight line distances between cabinet/exchange and
Postcode
 …but, straight line distances are the shortest possible path between
two points - implies being closer to the cabinet than in reality
− Better to use road network to find a path between each premise and cabinet
locations
 Ideally BT would (know?) share the route data or loop length
− However, data not part of supplier provided information
 Significant differences between direct and road distances
− Some premises connect to direct to the Exchange (EO DP) some homes are
connected via intermediate cabinets

26. 26SYNCHRONOSS PROPRIETARY
Limitations of straight line cabinet distances
2km more via the road than as a straight line distance
