Hi there !

A simple question. Where was the first wireless network ?

Was it in France in 1700 ??

I am unable to find it.
Kinldy help me with it.

thanks

The major use was to distrubute the winning numbers for the French
national lottery.  And yes... it was encrypted.

Guglielmo Marconi invented wireless communications in late 19th
century.
I dont think he had a network though so this may not be the answer you
want.

I had the first one..1984, wireless internet!

Bah...  I had the first mass distribution of Usenet content to BBS's,
without wires in about 1982.  I would copy the daily Usenet messages
and binaries from ihnp4 to a DC600A QIC cartridge tape, jump on my
bicycle, and deliver the tapes to the BBS owners.  They would also
return the previous days tape for re-use.  No wires anywhere in sight.
There was also some discussion of using rockets, model airplanes, or
blimp delivery, but it didn't fly.

Ahhhh..The BBS's with the C64
Come a long way, connecting with a Hayes a 2400 baud modem....

That's a long way?  I remember how snappy the 300 baud acoustic
couplers felt, migrating up from 110 baud modems.

About the same way I felt when we upgraded our 50 baud teletypes to 75
baud kleinschmidts!  Only a couple of years ago, it seems like......
Anyone remember Morse code?

I used to run 50 baud Teletype model 15 printers, model 14 transmitter
distributor, and model 15 typing reperf. I also had a Kleinschmidt
printer. Really different from the Teletype. I ran all this stuff with
850 Hz frequency shift keying on 3.625MHz. The first dot matrix printer
I saw was an Extel, which was a replacement for a Teletype model 15 for
wire service use. The first inkjet printer I saw was an Olivetti. It
was interesting in that each sweep of the print head only did one
vertical dot per sweep of the head.

As for Morse, I haven't used it in a while, but still remember it. One
of my projects for some day is to write a program that will generate
telephone ring tones in Morse. I'd like the ringer to just give me the
initials of the caller. Seems a lot easier than remember what dumb song
I assigned to each of the callers.

On old modems and such, my first modem was a 300bps modem I built using
an XR2206 and XR2211. I used this to call into the Source, an early
consumer timeshare service. The Source had a cross assembler for the
MC6800 processor. I had wire wrapped a small computer using it. I then
wrote my code online on the Source, got back the binary code (Motorola
S records) and sent them to an eprom programmer, burned the chip,
plugged it in my wire wrapped machine, and got it running.

My first internet was telnetting from San Luis Obispo CA to the
Cleveland Freenet where I had an account (ap621). Long time ago!

Thanks for the nice story Harold. It all brings back memories.

I didn't think there were any of us oldtimers left still compos enough
to be communicating on the Internet.  But none of this 850 Hz FSK for
me - we used military 16 channel VFT equipment ordered at great
expense from the US of A.  It used FSK +-42.5Hz, max channel speed
100wpm.  They were AN/FGC61A and we ran them over 10KW HF ISB systems
with rhombic antennas as big as a sheep paddock.  Satellites put paid
to all that.

UIUC campus to the phone exchange at the Chicago Circle campus and
back to the UIUC PDP-7, using looped-back lines (dial into the C.C.
exchange, then dial an access code to get a leased line, then dial
back to the UIUC campus to another 110-baud modem port on the PDP-7).

I did this to test long-term data integrity of the PDP-7 and its
comm.gear front-end.  The whole kit ran perfectly for tens of minutes
(sometimes a few hours) at a time, then a noise burst would eat the
data for a few minutes, then the links would "self-heal".  Eventually,
we discovered the problem:  some phone exchange operator at the C.C.
campus, not believing that anybody could talk for hours, would bridge
into the loop-back circuit to check for human voices, and would hear
only "whistling"; when the operator tired of listening and removed the
bridge, the links would work again.

I learned on a Model 26 Teletype.  It was possible to type at about 20
wpm, but no slower or faster.  You had to time the keystrokes exactly
right.  Too soon would cause the giant carousel in the middle to go
around again before typing.  Too late and there would be an excessive
delay.  It was also really noisy.  I graduated to Model 15 and 19
devices somewhat later.  Everything was baudot.

While going to skool, one of my summer jobs was rebuilding old
teletype machines for TELEX service.  Mostly Model 33ASR machines, but
some older 15 and 19's.

I went the other direction.  In the early 1960's, our high skool radio
club had a home made RTTY terminal (using tubes) complete with the 3"
CRT to show the crossed loop pattern.  When we obtained a Model 35
which we converted to ASCII.  The RTTY converter was immediately
butchered into a 110baud phone modem, and used to hack into all kinds
of insecure systems.

The popular AEA PK232 TNC used those chips.  Yuck.

Been there, done that.  Eventually, the Source became Compuserve.

Such development was common practice in the early 70's.  The company I
worked for did Fairchild 3870 development on a Model 33 ASR, and
Anderson-Jakkobsen acoustic modem (insert handset, close wooden lid,
pray that nobody touches the box) via various timeshare services.
Storage was paper tape. 

There was a big blur between BBS operation, usenet (UUCP), and the
internet.  My first real internet connection was via a dialup BBS that
hit the internet at TLG (the little garden) in San Francisco.  Prior
to that, it was Telebit modems polling uunet in Virginia, or prior to
that, ihnp4 in Chicago.  My phone bill was enormous.  I still use UUCP
over TCP for my email (because it always works).

Thanks for the nostalgia and memories of nightmares best forgotten.
