Damn, the time pass so f...in' fast!
Seems like yesterday that the tick ethernet ( yellow) cable was the
standard thing for back-bones.
>From my experience the distance if Officialy 500meters but I have
segmens of more than 600m but with only one station at each end.
The speed is standard 10Mbit/s Ethernet and every not crap hub will
offer you an AUI interface.
The cable has 2x50ohm terminators at the ends and you connect the cable
to the card or hub with some kind of insertion conectors with
transceviers that are on the same case ( the AUI net card doesn't have
its own line transcevier), friendly called "vampire transcevier".
Up until 5 x 500m cable segments where able to be conected with line
amplifiers ( small uninteligen boxes that some times were powered using
the cable itself) without routers or switches, giving you a max dist of
2,5 Km ( ever wondered why a typicall fibre segmat has this max lenght
).
The solution is rock solid and the cable is also resistent to about
ever abuse imagined, trust me ;).
But, if you want to try a radio sollution try
http://www.breezecom.com/, thei equppment is wonderfull and they operate
on spread spectrum in the 2,5GHz range that should be unrestricted if
your contry is member of ITU.
