I really haven't seen problems with power over Ethernet yet with carnet 
devices.  We had to replace about 30 YDI etherant's last year due to lightning. 
 All problem customers have since then purchased Ethernet surge enabled power 
strips or UPS devices with Ethernet surge suppression.  Only one has had 
recurring problems since then.   
I feel that integrated board and antenna combo's are just a headache.   
Especially since Carnet doesn't integrate the firmware for the wireless cards I 
use into their kernel.   An enclosed antenna makes it impossible to flash the 
card without destroying the unit.  And I like the ability to switch out cards 
and antenna's.  I like the ease of upgradablility as well.  If a customer is 
having problems because of some interference source that wasn't there at 
install time, I can just install a higher powered card or antenna with little 
effort.

As for snow.. well we get plenty of it... and just try to install to an area 
where we can reach directly with a ladder.  Otherwise we have a propane torch 
with a really long hose much like one used for burning weeds alongside a ditch. 
 
I don't use anything linksys because of their track record... so I don't know 
what the hype is about the wet11

For us, no integrated solution like the KN-50 is useful.  With mostly 
long range shots, we use DB-24 antenna's almost exclusively.  We also 
prefer to have our radio electronics where they can be serviced without 
climbing on to the roof or having to tilt over the antenna mast.  Winter 
weather here can prevent rooftop service for days at a time.  Due to the 
heavy tree infestation of our area, we often have 10-20 foot masts.

Also, having had many bad experiences with PoE, we have just about 
abandoned any use of it.  Every time we had a lightning storm or a windy 
but dry winter day we had to go out and reconfigure or replace our PoE 
clients.

What we really need is a reliable supply of the Ubicomm's Karlnet 
satellites or the upcoming Karlnet satellite flash for the Linksys 
WET11.  As we are currently converting from standard 802.11b AP's to 
Karlnet, the flash for the Linksys's would allow us to preserve much of 
our current hardware investment.

And, one last comment:  The loss of the SC-4700 will make signal testing 
harder for many of us.  Without it, it will be difficult to troubleshoot 
/validate antenna and cable.  Keep this product available, please!!
