The user end of the packet network runs at 1200 baud mostly, at least in
this country.
However, the digipeaters and BBS's are linked by 4800 and 9600 bps
backbones.
Higher speeds are more widespread in the US.
By way of interest, the Russian Space Station Mir has a couple of Packet
setups,
one is the 1200bps terrestrial system, in the 2m amateur band, which I have
worked
a couple of times, using just my normal 1/4wave on the roof.
They also have a more sophisticated G3RUH 9600 BPS modem
which I think is on a 70cm radio with their SSTV gear.
