Broadband Wideboys?

Interesting to hear that Virgin is piloting 200-400Mbps Broadband (in Kent, so they be hopful of a good result (bad spelling makes bad gags) without really knowing what applications it will be used for.

Here in Andorra they’ve also been rolling out FTTH and have that great application to run over the 100Mbps feeds they’re offering – Internet access. T’trouble is, the comms speeds out from Andorra (can’t be so much a fat pipe as a thin roll-up) is rubbish and the DNS is almost always out of sync, so it’s the finest waste of bandwidth availability ever.

Contrast this with a story this week in The Grauniad (still no spelling mistakes) on the excessive global footprint of the Internet: – http://www.guardian.co.uk/technology/2009/may/03/internet-carbon-footprint – and how the web providers must limit this and you see the folly of giving homes 400Mbps to watch Corrie Omnibus reruns on. Meantime, we continue to test and validate fantastic optimisation technologies – DBAM Systems, jetNEXUS, NetMotion – to name just three companies I’m currently working with that problem more for less (and with less) and you wonder why this technology isn’t de facto standard in every application and content delivery mechanism in the world, whether running across hi-band fibre between server farms or narrowband connections to middle-Africa or any mobile handset and all stops in between.

The reality is that you don’t need 200-400Mbps into the home, not for any useful application (or most useless ones either). Billions of WLAN connections are used daily and this is typically over shared 11Mbps or 54Mbps networks (and then only half of that bandwidth is really available to start with) and then there’s mobile and yet video is popularly run across these networks. And with .11n – see soon to be released Broadband-Testing report on ProCurve’s recently (ex-Colubris) acquired WLAN technology – we have genuinely usable wireless bandwidth now. Why continue to put fibre into the ground? Even if it’s already there (which is commonly is, but wasn’t in Andorra) it costs a fortune to light it.

Surely if there’s a message for the screwed up global economy that is 2009 it’s ‘optimise and rationalise’, not bloat out on bandwidth?
