Hi Peter -
"I was struck by the idea of using 2-D drawings to represent 4-D reality. Starting with economics is starting with time/money.
Starting with terrain is starting with 3-D space.
The engineering dimensions of wireless include time, frequency, code, space, power, aggregation. For Regulatory purposes, add National Policy, Security and International Relations.
All interference is local (in the receiver), and the spatial reuse of frequency is key to all."
.... All of which begs the question: can we use the spectrum gained from reallocation of broadcast video more efficiently?
"On the side, I'd note that frequency band allocations last longer than fiber - what is the remaining life of ESCON fiber?"
.... Life-cycle cost (per bit) of fibre exceeds that of any other "wired" medium. Frequency band allocations differ, can (and have been) changed, so long as the physics satisfy the requirements.
"The problem statement might be 2-D, but any one solution is of it's era."
.... Yes, and if you wait long enough, the era is past. Concede to status quo and an unknown future, instead of migrating to an immediate gain in total throughput - and the benefits it confers?
And, when the next technological advance (wired, wireless or both) confers even more throughput the change may be even more disruptive. So, will your descendants then say, "Nope. Better to wait."?
Perhaps. There are many scientists still searching for the flaws in Einstein's work.
Best to ignore it for a century or more, and wait for The Real Thing ;)
