[MLB-WIRELESS] Cat5 max length

[Joe Hovel]

Thank you all for the detailed information!
Please correct me if I misunderstood anything. For my particular
scenario:

LAN with switch....long cable run....AP---Antenna on tall pole

I learnt out of all that:
10Mbps may have a longer cable lengths then 100 (10 is OK by me, since
my WAN link will only ever manage less than that).
A (cheaper 10Mbps) switch (functioning as a repeater here) will manage
the timing of packets between my LAN switch (existing 100Mbps) and the
AP on the pole, the distance can then be more then 100m, because the
response to any packet is acknowledged and verified by the (repeater)
switch on each of the two legs from my (LAN) switch to the AP, before
the next packet is scheduled to be sent. That way no collisions or
unnoticed packet losses can occur.
I understand that a hub can't manage that - if there were more than two
ports in use, which is of course not the case here. Can someone try to
explain why a hub cant manage two ports without collision or loss
verification in time? I understood that a switch does this for many
ports by remembering who's connected to all the ports and not bother
sending packets to any other port than the one its intended for.
In this case, it will be irrelevant how many ports packets will be sent
to - only one (other than the sending one) will be connected.... 
I'm not trying to be annoying about this or contradicting anyone, I'm
trying to learn!
Cheers,
Joe
