Story: Why 802.11n is a hard act to swallow

Why 802.11N is hard to follow, at last...

Thank you,
This is the first article which I have seen which discusses the law of physics related issue of "there is no such thing as infinite bandwidth"

As a licensed Radio Amateur, I learnt that this is a fundamental... and all I have seen in both WiFi and in 3G are promises of infinite bandwidth. nobody, until now, that I have seen, has raised this issue.

My 'day job' is in IT and when this is raised with vendors they glaze over and either don't understand or pretend not to, as they have drunk at the 'well of infinate bandwidth'.

I think it comes down to this: everyone assumes they are the only user and therefore have access to all the available transmission space, as we learn in Amateur Radio, albeit on a smaller scale, that is untrue and the available space becomes overloaded, eventually degrading everyone's service severely

Thanks for bringing this to folks notice.
