WiFi without Relativity

Dave Weinberger’s Salon article claiming RF interference is a myth hasn’t gone over too well, according to Weinberger’s source, David Reed:

And of course, there are the usual angry letters that seem to think I’m claiming to have discovered the earth is flat, or that relativity is wrong (someone actually thought I was arguing that!)

Reed is most famous, perhaps, as one of the co-authors of the 1981 paper arguing for an architecture-neutral Internet. (If we’re going to start enumerating technical myths, I’d start with architecture neutrality; the Internet’s initial design wasn’t neutral, it was crippled with respect to real-time data transfer, but if you read this blog at all, you’ve seen that already.)

The weakest parts of Reed’s theories about RF signalling relate to non-informational sources of interference such as barriers, reflection, multipath, and entropy. Other than that, it’s a fine way to look at signalling in a vacuum, covering all the considerations that should be taken into account by the FCC the next time they deal with metaphysical policy.

Sometimes I think I could edit an entire blog devoted to nothing but debunking pseudo-technical BS.
