Humble pie time!

I assumed that the Renetech quote was accurate...
"That is to say, IDC was the first to patent a
system for mobile or fixed wireless radios that converts an analog signal to digital,
compresses
the signal, merges the compressed signal with other compressed signals into a single
transmit
channel bit stream ..., etc. In other words, TDMA.


After looking up the patent, I see what Renetech mean't

channel control means connected to the compression means for sequentially combining the compressed signals into a single transmit channel bit
stream, with each of the respective compressed signals occupying a repetitive sequential slot position in the transmit channel bit stream associated
with a predetermined one of the separate compression means;


But, not to be too hard on myself, Renetech missed out the key phrase
signals occupying a repetitive sequential slot position

I stand by the rest of what I wrote.

Terrapin. - This patent was filed in 1985. How do you think it stands up with regard to the prior art, especially regarding DARPA work?
