That is good to know, that there was actually technical merit, "brains", behind the decission to do it Alvarion's way. I think whats more important from this is that anyone installing VL, and needing to extend the cable longer than the cable included with the unit, probably then also needs to wire the new longer cable or extenstion cable with the same pinout. I bet many had attempted to use a 568B extension with a coupler to the Alvarion cable, if they were not aware of this. The cable length that comes with it is probably fine for Residential, but for MTU's 150-300ft is not uncommon.
What is the cable limit for  Alvarion's CAT5 connection?

Now to give you a hard time.... Why does the Alvarion use 56V instead of standard 48V, 24V, or 802.11af? :-)

Subject: [WISPA] Brad B, I got your answer on the pinout for BreezeACCESS VL

So Brad, I finally have the answer as to why we do not use the standard 568B (or 568A for that matter) pinot. We can't. The VL PoE pushes 55 volts and ½ an amp up the cat 5 cable. If the standard pinout is used the cable range due to cross talk can't make it much past 30 feet. With this pinout we are able to maintain the long distance.

So, you may not like it, but at least I've finally been able to give an actual reason.
