Fronthaul networks, preferably fiber, to a 20+ year concentrator (not a
802.3 switch) at the same location of an electrical panel. Get rid of the
SoC and AP which is basically a Sun workstation with NICs and use remote
radio heads (or in switch speak, port ASICs.) This design will work for
50+ years or the lifespan of most buildings. One and one. Best return on
labor possible. The MTBF shorter lived parts are replaceable like light
bulbs or sprinkler heads.
Spectrum is not limited. Paul Baran pointed this out in 1994. Probably a
good idea to stop with that property rights theory of limited spectrum.
- Shorter range rf transceivers connected to fiber could produce a
significant improvement - - tremendous improvement, really.
- a mixture of terrestrial links plus shorter range radio links has the
effect of increasing by orders and orders of magnitude the amount of
frequency spectrum that can be made available.
- By authorizing high power to support a few users to reach slightly
longer distances we deprive ourselves of the opportunity to serve the many.
- Communications systems can be built with 10dB ratio
- Digital transmission when properly done allows a small signal to noise
ratio to be used successfully to retrieve an error free signal. And, never
forget, any transmission capacity not used is wasted forever, like water
over the dam. Not using such techniques represent lost opportunity.
The solution isn't to shrink bw and increase range. Spacetime includes
space and freespace pathloss works in favor with digital communications.
Let'st stop blasting RF energy all over the place. We do this for water in
irrigation systems already.
Also, there are two optimums. The transport layer optimum and the link
layer optimum. That's the core issue and the reason it's been "hard to fix"
My $0.02,
Bob
