Frequency combs?  What about bald people?  That is hair discrimination!

Yes and no...dispersion and phase variances will become more and more problematic, so the front/back-end processing will increase geometrically to exploit such bandwidth

thats why we will have nano tech combs to extract the frequency nits

SCIENCE!

The physics of the thing normally dictate that higher frequencies mean higher data rates, correct?. Although I presume you could push any given range of frequencies "harder" and just rely on more front and back-end CPU time to clean it up to some degree too.

What I meant is once the dispersion is substantial over the bandwidth, there is multi-path across even a collimated beam if it's going through real materials that are non-uniform (air)--meaning space-time adaptive processing (eg MIMO) will be required to clean it up, and the complexity required increases with the square of the effective number of paths...so in this case, while a typical cell phone at 10Mbps and 2-4 antenna diversity can get a way with say 0.1 GMACS of DSP, a 100x increase would require 1000 GMACS...

The higher the spatial-spectral density, the more complex the encoding...the ability to modulate at these high levels means that the computations necessary to lock in on the minute variations become even harder.

Ah. I see, you're pushing it so hard, speed of light differences and other effects you can safely ignore today become significant , and somehow you've got to actively clean that up.

Although that begs a completely different question, could the interference and delays that make such high bandwidth difficult, also make this technology useful for sensing and mapping an entire region like some sort of mile-wide MRI (obviously not an actual MRI but you get the analogy...)?

Fun fact:
All fistful-blaming to date actually happened after this service became commonplace.  It is that fast.

I have a feeling it has potential, but not for the moment.  Maybe for fixed site emplacement or special needs, but it'll probably be a waiting game for DSP's to catch up.

How well would this penetrate obstacles?  The article says "operating between infrared and microwave light" ... we're talking about something that would be blocked by a wood panel, aren't we?

Just crank up the wattage more.  :angel:

Especially in municipal areas in cold latitudes. People are chilly there to begin with.  =D

Depends on the frequency and composition of the obstructions. Salt water will pass light well, but not radio.  A sheet of drywall, the reverse. Optical and microwave are generally LOS, yes. There are microwave transparent material.
