Dr. Fehrer's book from U of San Diego or Robert Winch's one.
Both covered this. Isnt this what AT&T is pushing in
commercial about Picocells?

Actually...CDMA techniques (PN modulation) re-channel a
band based on time rather than frequency. In a multi point
environment, this allows multiple people to share a
frequency bandwidth in a not terribly inefficient way when
all of the simultaneous communication paths are considered.

Yeah, isochronous pseudorandom noise mod/demod
techniques will pull info from sewer. I think the
deep space network uses some of those techniques.
But PN modulation does not help throughput. It wastes
bandwidth.
Speed/interference immunity/narrow channels – pick one.

The holy grail would be the ability to modulate a
signal and receive it correctly in the face of
withering interference.
The GPS system accomplishes that through the technique
of encoding the data within "pseudo noise". The only
problem being that GPS data is relatively static
compared to what we deal with.

The only way to scale this this stuff in a way
approximating Moore’s Law is to just keep adding
cell/ap sites.
I read a book back in 1990 that outlined this problem
for the nascent cell phone industry. The book is
still spot on.

Is it just me, or is no one realizing that we are
still not that far from 2005 with wireless.
Yes, we have 300-1Gbps capable radios.
But they trade that for larger channel allocations
and even more signal to noise requirements.
But the spectrum allocations haven’t changed enough
to use these new features to their fullest in a radio
dense environment.
When doing cost analysis in my area last year for
wireless I realized I had to forklift upgrade most of
my network, and build towers out in a half mile range.
This was to get the 30Mbps plan rates to really work.
The costs were skyrocketing because of all the towers
and sectors.
I think the real winners of late are still the rural
and low density wireless provider domains.
They are the ones with clean enough spectrum to cost
this competitively.
