Millimeter Waves

OR it could be NSA's new ultra-imaging technology to see who's packing, and who is is a non-threat?

I know I saw a blurb on millimeter wave imaging tech somewhere.

I think this is cool, but if it does to the average person what it did to the dudes in the picture down at the bottom of the article, we will all be bald and have to wear knit watch-caps all the time.

I could see this would work in rural flat areas where it could be mounted on a tower. Waves that short are line-of-sight.

the company is still working on finishing: a two-foot-high rooftop unit able to serve between 600 and 900 customers within a roughly one-kilometer range.. it isn't just line of sight.

Metricom Ricochet, Wimax, etc. The spectrum, frequency, echos, reflections, atmospheric anomalies, etc. for wireless are seemingly endless combinations of trade-offs, compromises and electromagnetic gridlock potential. Years ago a seasoned hard core RF engineer friend in the HAM cult opined that for wireless to really work, it would have to be daisy chained on a local long wave level from computer transceiver to computer transceiver, then at a second shorter wave tier in a sub-regional network (e. g., cell towers) then into fiber trans and inter continental fiber systems, or, where latency could be tolerated, to satellite arrays. I guess we are sort of trudging along in this direction with CATV based systems creeping across the land.
