-features such as fast 800 Hz forward power control
How fast is fast??
- new modulation and coding schemes
Bless the idea of coherent reception, as in GSM and
WCDMA, it was tough in the noncoherent times of
rectifing tubes and big coils (coherent demodulation
is still a difficult thing for 2de year telecom students)
-Significant standby time improvements
never too late to learn the needs of the end-user
-fully backward compatible
Tough thing when rebooting WinDos, luckily WinMe
needs a floppy to boot DOS, NT and 2000 don't do it
at all.
(and Intel might finally fix the MSFT kernel??)
-support for packet data
Like GPRS???
-a full Internet protocol suite
Wireless is kind of differanet than old US government
sponsored arpanet. (why,o'why did AT&T not say thanks to
that free gift??)
- exceeds the ITU's 144 kbps requirement
as EDGE, also demanding linear power amplifiers,
not really much more than GPRS, ask Shannon (sorry,
too late, ask Viterbi)
-ARM7™
Bless the british RISC guys, the Commodore and Amiga.
-64 forward link channels and 32 reverse link
Running out of Welsh codes???
-four-fold increase in the number of simultaneous calls per channel card
Count your channel cards... (ridiculous statement, except
for poker players)
-Viterbi and Turbo decoding
Viterbi is a smart guy, like Shannon and Nyquist
(although, just like CDMA, some russians were kind of
earlier, but not the topic of this month of honouring,
mourning Shannon, great-great-great guy)
- is now sampling, expected
any healthy male and female has done some sampling,
production in the millions is the real test, not
just expectations.
Ilmarinen
P.S. Liver damage?? probably some, even degenerating
neuron networks, cannot but imagine the corridors
of some companies, the lost time due to adversarial
managerial hype.
P.P.S. Another couple of greats for Shannon! |
