Sorry but it's not. Even with ancient wiring, signal quality is fine after this distance. Try it - scopes are cheap and handheld these days. That's not the issue.
The issue is timing and the "length" of the packet (literal length, as in the length of wire the packet occupies, given the speed of electrons in a conductor). Yes, having only two parties will make collisions less likely. And with only two parties you could likely go half-duplex successfully (yes it cuts your bandwidth in half, but it should also remove most or all of the collision issue. I would ask one question: have you actually strung a longer-than 100m length of network cable? I have, both the "ancient" types and the CAT5/5e/6. My experience is that you get lots of collisions, even though an injected signal scopes out just fine. Even a TDR shows no problem end to end. So... go read up - or break out, say 600' of your preferred UTP, stick it between two switches and see how that works. If they're smart switches, you can get collision reports without any other gear. -- bobkoure ------------------------------------------------------------------------ bobkoure's Profile: http://forums.slimdevices.com/member.php?userid=14646 View this thread: http://forums.slimdevices.com/showthread.php?t=79140 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
