That was the first idea. Option exhausted.

Well we've really hit the ceiling with 15mbps now. There are all kinds
of citrix connections breaking, files can't be transferred etc. Think
30 desktop/laptops in each location with most of the servers in one
location. 15mbps doesnt cut it, and we'll quickly hit the ceiling with
50mbps since at least one site's switch will be gigabit. We have a
dual subnet setup, and with the citrix licenses it all adds to the
running costs. Not to mention the additional servers for the second
site. We'll maintain it as is if theres no feasible option, but it
never hurts to fish.

Someone else mentioned this to me. In Canadian dollars, including tax
etc its 75000. I'll keep this at the back of my head if the company
really grows.

Wave wireless sells (802.11g based) 108mbps for way less. Problem is
given the protocol you cant aggregate the links properly, two 108
links or channels dont add to 216. Cant do etherchannel either. This
is the most likely way to go for us if the telcom wont even take $$$
to lay fiber.

Dlink and now Linksys sell APs at 802.11n that can do ~100mbps and
theoretically 600mbps in time. Jack up the power and add directional
antennae and I'm golden. Just thought there might be something better
out there I haven't heard of.
