Sharon White can raise Internet speeds across Britain by 100 megabits with smart policy. British Telecom, Vodafone, Sky, and TalkTalk would all benefit if White gets this one right. More important, the Brits get a much better Internet. The only losers would be John Malone's cableco and the now outdated policy for sharing of the binder. (BT has promised 10M lines of G.fast at speeds of 200-800 megabits. My examples here are from Britain, but other countries will face similar issues.)
Competition doesn't have to die. It does have to move from the cable to the exchange. Unbundling was a great idea in 2000 and is the main reason European broadband is 30-70% cheaper than American and Canadian. The 25 or 50 twisted pairs that run together from the exchange could be split between several carriers and performance was unaffected.
Future competition will require BT's local loop monopoly to hand off to others at the local exchange at the right price. The "right price" would include a profit proportionate to the investment. BT would be welcome to recover costs plus a profit; regulated prices would prevent exploitation of the monopoly.
That was the near-ubiquitous model for unbundling until recently. Currently in the EU, monopolies are being allowed to charge far more, after Kroes and Richards were blinded by a lobbying campaign brilliantly orchestrated by Luigi Gambardella.
