2M USC and Rural Digital Divide


A draft Requirements Document put out by BDUK contains a couple of interesting snippets, at least in its current form. The invitation to comment has now closed.

The 2 Mbits/s Universal Service Commitment is now being expressed as "a minimum edge-of-network throughput of 2Mb/s and that most solutions will exceed 2Mb/s". Throughput is defined in the document as being measured by transferring a file and measuring the time taken, so it is the actual useful data throughput without overheads rather than the sync speed, IP profile or other higher level measure.

Interestingly, this means that a 2M fixed speed ADSL service will not meet the USC requirement as expressed, because the measurable throughput of IPStream Home 2000 is at best 1900 kbits/s. Current MaxDSL services will need an IP profile of 2500 to meet the spec which is a sync speed of at least 2848 kbits/s at the ATM level.


In the same document (p19) an example of a Local Authority call-off shows the speed vs rurality hierarchy at the core of BDUK's plans :-

5A1 Delivery of 50Mb/s to xx Market Towns (Example) L2
5A2 Required for delivery of 20Mb/s to 50Mb/s to xx Villages L2 (Example)
5A3 Delivery of < 20Mb/s to xx Hamlets (Example) L2
5A4 Required for delivery of xx Community Hubs (Example) L2
5A5 Required for delivery of 2Mb/s to edge of network access speeds L2
to xx Rural Communities (Example)

So if you live in a Hamlet (OS definition " small, isolated group of houses without a church. ") then it's ADSL2+ or less for you. Granted it's an example, and the document is a Draft, but it does suggest what we have to look forward to.

Another recent BDUK publication is the Data Model Explanatory Notes which accompany a model that appears not to have been published. This model looks quite interesting as it calculates funding requirements and costs for deploying various broadband solution. It also reinforces the notion described above that isolated and sparse rural types will be getting BDUK's slowest offering :-

" The superfast broadband model therefore calculates costs and revenues for the final third on a cabinet by cabinet basis. The cheapest cabinets in terms of investment gap per customer served are upgraded first until a floor threshold for fibre coverage (e.g. 90% of premises) has been reached in every Local Authority area and fibre connectivity to every community has been provided.

Premises that are expected to receive less than 2Mbit/s, after targets for fibre coverage have been reached, are input into a wireless and satellite cost model. For 10x10km grid squares with a population density above a chosen threshold it is assumed that a wireless mast is constructed, and all premises in grid squares below this threshold are served with satellite. "

From this I conclude that if you can currently only get 2M ADSL then you'll be offered a wireless solution if the population density is sufficient, or a satellite dish if not.

BDUK and Community Broadband

The ongoing process to try and connect up 1/3rd of the country for less than £60 per home rolls on with the publishing of their first "Delivery Model" document and related procurement announcement of around £2bn of public sector contracts, picked over in depth by Lindsey Annison.

The Delivery Model has several references to community engagement in broadband provision, with the word "community" featuring 93 times in the 60 page document. Selected highlights are :-

Point 7 of the Executive Summary sates that "Contracts are expected to include provision for Community Broadband Hubs where there is sufficient demand for them" and goes on to suggest they are exploring what the specification of such a thing might be and what demand there is for them.

Section 2.4.1 makes it clear that Community Groups are part of the intended audience of the delivery model document and Section 10 sets out potential roles for and involvement of such groups. Principle 3 (4.2.3) is to "Promote the involvement of local communities" including to "Explore the viability of the provision and use of a Broadband Community Hub at a local level". Principle 11 is to maximise competition " including SMEs and community suppliers as appropriate".

Section 9.2.3 looks to community champions to support demand stimulation, against a background where BDUK see potentially low takeup of superfast broadband in areas that currently have a workable standard broadband service.

In section 10.2.4 the bar is set for a local community to be at least 100 households that are sufficiently concentrated to be connected to a single "point of presence". A target of at least 40% of households signing up for the setup and monthly charges of any proposed community scheme is suggested as a minimum.

BDUK have funded The Rural Broadband Partnership at ruralbroadband.com to act as a focal point for Community Broadband issues, presumably burying the Community Broadband Network's role in this sector for good.

In Section 10.4 we get down to the nitty gritty of delivery, with BDUK stating that "In the majority of cases, community groups will not be involved in the actual delivery of the broadband infrastructure". They see a role in "raising awareness", "stimulating demand" and informing local bodies (Councils) of the community's needs. They go on to say that "In a minority of cases the community may become involved in the delivery of broadband infrastructure. This is expected to happen where the proposed broadband investment will not otherwise meet the community expectations. It may involve the use of a Community Broadband Hub."

Section 10 is fairly inclusive in its approach, while at the same time fairly dismissive - "Demand for this option is uncertain", "Demand for this option is unproven" and so on. The three main options identified for Community Networks are :-
  • Community access point - support of an existing access point with an affordable annual rental and monthly bandwidth charges.
  • Community network extension - arranging wayleaves or digging in ducts etc to facilitate extension of a private sector network where the community doesn't wish to build or maintain the whole network but at the same time wants more than is on offer on the usual commercial basis.
  • Community design and build - the whole network owned and operated by the community.
So the document provides hooks for community projects to latch on to, but the money simply isn't there to give them the handouts that most will crave. It does have sufficient references to Community Broadband Hubs to make it difficult for Councils and their large corporate suppliers to totally ignore them, but at the moment the references are so vague they don't cast a lot of light on the subject.

Hopefully subsequent versions will firm up on the Community Broadband Hub concept.

Community broadband gets "Parish Pump"


The wireless community broadband network serving Wennington (Wennet) is looking forward to increased connection speeds as they start to take advantage of a "Digital Parish Pump" in nearby Wray village :-
Wennington's network was originally built using Locustworld 802.11b wireless mesh boxes and had its internet feed provided by Lancaster University Network Services ( LUNS ).

The feed was contractually 2 Mbits/s symmetrical (same upload and download speed) but in practice could burst to higher speeds. The first wireless link to LUNS was carried on a public sector educational network CLEO which has recently been transferred from LUNS to a BT-led consortium that has indicated that it will only guarantee to supply service until February 2012. Technical changes have also reduced the burst speed to the contractual 2M limit which has reduced the service quality for residents and businesses.

Wennington is therefore faced with a challenge of replacing their "middle mile" internet feed, increasing its capacity to handle more users with increasing usage, and upgrading their wireless network internally to escape the constraints of 802.11b.

A potential solution has appeared in the form of a "Digital Pump" facility kindly negotiated with a Lancaster University Network Research & Special Projects Unit project in nearby Wray. This project is an extension of the University's NRSP Living Lab rural broadband project into the arena of television over the internet including P2P broadcasting. As part of the project an increased capacity feed into the village was required and the project has procured a WEES fibre connection from BT Openreach to connect the village to the university at 100Mbits/s, over which 20 Mbits/s of internet transit will be carried for Wray village.

It is the presence of this fibre and the ability to add a further 20M of internet transit to it that has provided a way forward for Wennington. With the £10.4k pa cost of the fibre already absorbed into another project the internet connectivity becomes available at £6,000 pa for 40 Mbits/s at 5:1 contention. £500 per month ( £12.50 per month per Mbit/s) is the sort of figure that a community network of at least 25 users has a chance of affording and the extra capacity will allow more subscribers in notspots to be brought onto the network bringing in extra revenue. Initially 20 Mbits/s will be purchased for Wennington and 20M for Wray.

The "Parish Pump" costs £6,000 pa for a low contention 40M internet transit plus £10,400 pa to rent the BT fibre in the "middle mile" 12 mile run back to the University network centre. This latter charge is distance related, and would be twice as much to reach out to Wennington directly. In the case of Wray a £7,500 "excess construction charge" was applied by Openreach on top of the 2 * £975 installation charge - this covers costs above those allowed for in the standard price.

For comparison a BT leased line of 30 Mbits/s on a 60M bearer was quoted at £64,000 pa with an initial cost of £76,000. So the Digital Parish Pump is providing 40M for less than one third of the annual cost of a leased line. An additional 40M would cost less than £6,000 pa using the existing and paid for fibre, showing the benefit of having a broadband supply point in the village rather than buying individual services from a remote point.

As part of the Digital Parish Pump service the users of the network are allocated an IP address by the University network services, however Wennington owns its own IP block and could equally use those once the appropriate entries were in the routing tables. Email and other services are used from "cloud" providers like Google Mail and no other services are included with the "raw" contended internet connectivity.

Now that the Digital Village Pump / Parish Pump is on stream a wireless link using equipment supplied and configured by NextGenUs has been established to connect to a nearby farm that is also served by the Wennington network. The link was installed by the local aerial installer and Wennet team members and paid for by Wennet CIC. Early work on the wireless routing and equipment options was done by the University under a commercial contract paid for from an NWDA Innovation award received by Wennet in 2008/9. NextGenUs did the final wireless survey and planning, with help from Google Earth and the local knowledge of community broadband volunteers.

Everything is poised for action now as two other users connected by fibre to the farm are enjoying the new service and a progressive rollout of enhanced wireless devices connecting back to the Digital Village Pump (DVP) via the farm is the next step. Plans are also afoot to dig a fibre optic cable to the DVP replacing the current wireless link to the farm - this will provide higher capacity and greater reliability.


Initial speed tests from the farm have exceeded 30 Mbits/s both upstream and downstream :

The only cloud on the horizon is that the University's funding of the £10,400 pa fibre "middle mile" connection does depend on externally funded projects beyond 2011. Should that be in danger it is possible that Wennington's network could expand enough to carry the cost, providing the financial and voluntary resources are available to do the job in time.

In providing rural next generation access it is this "middle mile" that is often an insurmountable problem. Internet transit charges are low compared to the cost of extending that connection out into the countryside from a metropolitan data centre. Rented BT fibre circuits have an install cost and an annual rental price per end plus an annual charge of 36p/metre (£360 per km, £580 per mile) for the "main link" connection between exchanges if the two ends are not served by the same exchange.

Thanks to project members for the Skype interview and information on which this post is based.

Can a County Council manage ?


Reading an excellent article by Robert Dale I started to reflect on how the likes of Cumbria and Lanacashire County Council are handling their broadband projects with part of the funding coming from Broadband Delivery UK (BDUK) .

Both counties have EU public tenders out, currently viewable online Lancashire and Cumbria.

Robert says that "local authorities should make finance facilities available specifically for these communities to move ahead with their own broadband when and where possible" but I really don't think they are up to that task in the way they currently operate. I say this based on my previous experiences in the private sector where we managed a capital investment programme of £20 - 60 million per year. It may be helpful to compare the approach taken.

I worked in a multi-site manufacturing company where we made investments to increase profitability through cost reduction or new products, invested in replacement works for equipment at the end of its life, upgraded facilities to meet new regulatory or other standards, and so on. There was active competition for the capital funds from the factories and we could have easily spent double what we had allocated by the Board of Directors. The administration involved a handful of people with a larger committee of technical and financial gurus joining senior line managers to argue out which projects were funded, canned or deferred. We'll call this process our "Capital Expenditure Committee" or CEC.

In the Broadband case we could cast BDUK as the Board of Directors, or maybe the County Council or its Chief Exec, setting the size of the budget. The officers of the Council could be equivalent to our CEC. If they were they would probably divide up the money into categories - for example Broadband notspots, Village pump pilots, FTTH pilots, Improved mobile broadband coverage, etc etc - and invite people to make submissions for funding. However they can't work like that, because they don't have any "customers" for the capital projects like we had factories.

In our case when a factory bid for funding and won it then they would procure the engineering and other services to deliver the project. Some of the resources may be their own labour, others would be bought in. The Factory Manager had responsibility for delivering the project on time and on budget, and was also effectively the "customer" of the CEC process in getting access to the money. Their submission for project funds would typically have to include detailed costings and supplier tenders at the later stages, we had 2 - 4 stages of application over 18-24 months depending on size and complexity of project.

The County Councils don't appear to have any customers. There isn't a mechanism in place for a community leader or broadband champion (equivalent to my Factory Manager) to ask for money from one of the pots or to influence what gets delivered in their area.

What we see in practice is the County Council writing a tender that effectively outsources the whole intellectual project of managing the expenditure and delivering the benefits. The large company winning the tender, for example BT, gets to make all the decisions about what to do where. It is responsible for delivering what it says it will at the tender stage which means a massive conflict of interest where the suppliers of goods and services are the same people deciding the best way to deploy those goods and services. The end users and local communities have no voice in the process.

A possible approach to match what Robert calls for, along the lines of my previous experience, might look like this :-

1. BDUK and County Council / Chief Executive define available funds, priorities and goals of expenditure and sets total expenditure budget.
2. County Council decides how to break up the total into parcels of expenditure to cover areas of activity, priorities, geographical areas, etc etc.
3. Community groups, local small companies, 3rd sector bodies, County Council departments, District or Parish Councils bid for appropriate funds to do their project to meet one or more of the objectives. Let's call them project sponsors.
4. County Council officials, BDUK, invited experts form a Capital Expenditure Committee to award funds to the best projects to the Project Sponsors based on the case they present.
5. The Project Sponsors procure necessary goods and services to deliver their project and manage its implementation.

With this approach there is no single large scale tender. There are multiple opportunities for SMEs, local companies etc to be Project Sponsors and get funding to deliver something. There are opportunities for suppliers big and small to tender for supplying goods and services to the Project Sponsors. There are opportunities for the 3rd sector to be a Project Sponsor, and so on. In other words it creates an eco-system of enterprise and empowerment to deliver an overall goal.

Would this deliver a better outcome than a single tender to a company with a turnover of at least £100m pa, as specified in at least one of the tenders ?

Let's try to illustrate the difference :-

Upgrading infrastructure

Neelie Kroes, Vice-President of the European Commission responsible for the Digital Agenda, recently called for more action to deliver access to superfast broadband in pursuit of that Agenda.

Bemoaning the decline in rate of new connections she said that "Maximising broadband access obviously takes a mix of players and a mix of technologies, and the role of fibre is central."

It is good to see both mix of players and mix of technologies given prominence. The UK's current public sector broadband procurement process seems to be working against the former, and if your tender results in a choice between hammer providers you're going to get a solution involving only nails which works against the latter.

Personally I would like to see more diversity at the heart the BDUK pilots and funded projects. It should be a specific objective to try at least 5 different approaches in both technology and delivery organisation - otherwise BDUK and the County Councils are left trying to predict the best medium to long term solution without giving the other solutions a decent run for the money.

It would also be good to see more tolerance and acceptance in the debate around broadband delivery. If fibre to the cabinet is adequate for 10 years in appropriate areas then should we not welcome the provision of extra bandwidth as part of Neelie's Digital Agenda and the economic hopes riding on it ? Why do we spend so much time decrying solutions other than our own favourite - a sales tactic I have never liked. Can we not celebrate any increase in bandwidth or coverage if it helps someone in some way, especially if it pays its own way ?

The last twenty years has seen bandwidth grow in steps by changing the technology at each end of existing copper infrastructure. From 9600 baud modems through to 56k modems, then ADSL from exchanges, ADSL2+ and now VDSL2 from cabinets. All have been relatively low cost stepwise upgrades that have seen us get 18 million broadband users in the UK. The money spent on this has not been wasted, and investing in FTTC is not a waste of money if it pays off the investor within the useful life of the assets.

If universal FTTH will cost £5, 10 or £30 billion then the interest we save by deferring that investment by a year is a very substantial amount of money. So it makes sense to me to upgrade the infrastructure as and when it ceases to deliver adequate services to a location, and not get in a huge rush to spend money we don't have to meet a demand that maybe isn't actually here yet.

For some locations the time for an upgrade was 8 years ago. 10km of twisted pair copper isn't going to deliver an ADSL broadband service of any speed so there is a case to re-engineer such locations with either fibre optic connections, wireless or other solution that provides the needs of the user economically. These locations may be predominantly "rural"but some will be in built up areas and "electrically remote from the exchange" is probably the guiding principle.

If we draw an 800m radius around a BT cabinet the area covered is 2 sq.km which with 80,000 cabinets gives us a coverage of 160,000 sq.km. That's 66% of the UK land area, but only if we're lucky to have no overlaps and an even distribution of cabinets across the land - which clearly isn't the case. We are still left with at least a "final third" that is out of range of the "cabinet circles", plus a good number of customers that aren't connected to a cabinet at all. Even adding in VDSL2 from the exchange only adds another 5500 circles so less than 7% extra.

Where I'm heading with this is that there are places which have had no broadband for 8 years, like Ashby-de-la-Launde, and we do not appear to be addressing them as a specific target. Rolling them up into a county wide scheme may still see them left out as "the uneconomic part" as councillors seek to deliver maximum connections per public expenditure. Should we not identify them and have a specific plan to solve their problem ?

Do we need a BT Openreach product that is a single run fibre optic upgrade from exchange to premise that could be ordered in the same way as a new telephone line, perhaps. This would start the incremental upgrade to our telecoms infrastructure in the areas that are currently the least well served.

If we don't have a plan for BT to upgrade its infrastructure, or for Virgin Media to expand its, then we need a plan for an alternative infrastructure in areas where the existing services are inadequate. This probably means a plan to specifically not spend public money within 2 or 3km of a BT telephone exchange, other than in exceptional cases with demonstrable infrastructure problems.
