Ofcom: Level playing field needed for rural broadband

Summary: Ofcom chief Ed Richards says the regulator will require competition in rural broadband networks, and is backing wavelength unbundling as a possible way to ensure fairness in fibre rollouts


Publicly-funded super-fast broadband networks in rural parts of the UK must allow open access to a variety of internet providers, Ofcom has said.

Ed Richards, the regulator's chief executive, said on Tuesday that single operators should not be able to dominate rural networks, as this would hurt competition and innovation. He also said a long-term solution to more effective fibre network competition might lie in a technology called wavelength unbundling, which would let different operators share a fibre cable by using different light wavelengths.

"We believe that open access must be provided as part of any publicly financed initiative, together with interoperable standard systems which maximise the potential for effective downstream competition," Richards said in a speech at Total Telecom World conference. "The danger otherwise is that we end up with single vertically integrated providers in a range of areas and an absence of choice, innovation and competition."

Richards added that letting one operator hog the rural broadband line would be "a particularly egregious outcome if delivered by virtue of taxpayers' money rather than private risk capital".

ISPs attack 'inequitable' BT advantage on rural fibre

Smaller providers say the UK's 'fibre tax' system means that BT will win most of the cash the government is offering as subsidies for rural super-fast broadband

The government is in the process of distributing £530m to operators for building super-fast broadband networks in rural areas, which the operators would otherwise see as poor investments due to their low population density.

BT is the main company rolling out fibre to the majority of the UK, with a focus on densely-populated areas. The firm says it will offer fibre-based broadband access to two-thirds of the population by the end of 2014, drawing on its own coffers, but chief executive Ian Livingston noted last week that the government's additional funding should lead to 90 percent coverage by around 2017.

Virgin Media decried the situation in September, claiming BT would probably end up as the sole provider of fibre-based connectivity in most of the countryside.

In the era of copper, the UK regulator's way of ensuring real competition was to force BT to allow local-loop unbundling (LLU) — in other words, to let other operators physically install their kit in BT's telephone exchanges, taking BT and its wholesale products almost entirely out of the equation.

The European Commission wants the same to happen with BT's fibre network. However, Ofcom is keen on a different system known as virtual line unbundled access (VULA). The Commission has approved VULA as a way of ensuring BT's rivals get a better chance at being competitive, but only as a temporary measure.


Wavelength unbundling

A possible long-term solution to the problem might be a technology called wavelength unbundling, or, more properly, wavelength-division multiplexing (WDM). Whereas a current fibre network uses one pulse of light, this advance would let competing providers offer different services using the same single cable, by each running their services on different wavelengths.


Apart from potentially increasing capacity by four times, this would make it a lot easier to ensure competition among the suppliers.

The idea of WDM has been around for decades — it is needed to run bidirectional signals over a single fibre strand, for one thing — but it is still being developed. Ofcom is working with telecoms bodies such as the International Telecoms Union (ITU) to help finalise the standards.

"Wavelength division multiplexing is already used in the core network but as the economics improve, and with the right equipment at the head-end and in customers' premises, it is expected to move into the access network also," Richards said. "With these elements in place, the potential may exist for a competition remedy — unbundling at the wavelength level — in which different communications providers address individual customers each using a different wavelength."

However, Richards noted that WDM was unlikely to be a possibility for end-user access before 2015 at the earliest.

For now, Richards said, Ofcom is focusing on VULA for the 'two-thirds' commercial fibre rollout, and on regulation of duct-and-pole access prices for the government-subsidised rural deployments that will make up 90 percent overall coverage.

However, this leaves the final 10 percent, which will probably require a mix of local, regional, national and European funding, and will almost certainly need a combination of wired and wireless technology. Given that VULA only works on wired fibre networks, and that wireless connectivity has nothing to do with BT's ducts and telephone poles, Richards indicated that he was particularly concerned about competition in these cases.

"We have worked with the government to identify some key criteria to ensure that public investment is the friend of competition and not inadvertently its enemy," Richards said. "While I have emphasised the challenges of investment and of new technologies, we should be clear that there is no future in which we will not support vibrant and effective competition."

The Ofcom chief also addressed the crucial issue of people actually choosing to use super-fast broadband. He noted that subscriber numbers were "still low" and theorised that this was because there is no "killer app" that demands such fast speeds, apart from several members of a household using the internet at once.

"Amid a cornucopia of entertainment and information services, and the promise of advanced telemetry, e-health and interactive education, it is interesting that the only 'killer app' we have so far is the presence of teenage children," Richards said.

"So there remains uncertainty within the sector about the level of demand for superfast services and of course willingness to pay. Yet it is clear that consumption of data continues to surge."

    If anyone lays fibre in a rural community it doesn't matter in the slightest if they are the only operator. BT have a monopoly, new networks will provide competition to the incumbent. We don't need competition between ISPs - let them concentrate on the old copper stuff. What we need is a level playing field so we can have more entrants. BT are never going to provide a solution to the final 10%, so let someone else have a chance. The major telco aided and abetted by ofcom are throttling innovation to protect the copper cabal. All this talk of 'fibre based, superfast' broadband is only from cabinets. souped up copper. It isn't the future, and its time everyone saw through the hype. It is probably adequate for now, but the final solution is fibre to the home. This should be being done in rural areas, where take up will be greater. Remove the VOA tax so that companies like Rutland and Vitesse can do it. Make councils relax planning issues. Make Railways allow bridge crossings. Stop the environment agency tying up river drills in wasteful bureaucracy. Lets get some rural networks built to provide competition, because a rural fibre gigabit network will make the telcos up their game before it reaches their golden goose of the cities. That golden goose is dying and won't lay many more golden eggs. Cabinet in cities won't have great take up, because the areas the cabinets are in generally have decent adsl. Perhaps when they turn it up to 80 meg there might be some interest. But even with the cabinets, many on them will be on the 'down to' figure, not the 'up to' one. Why can't we see through the hype? What is a regulator for if not to dispel the myths?
