Check www.gnswireless.com (this from a satisfied customer)
That said, I also use the method of placing mini ethernet switches or
hubs (electrically a multiport repeater and damned hard to find now)
every so often to reach distant parts of our warehouses. These are
powered, of course. POE might work if you only needed one or two repeaters.

David,
You can run upto 1.5 miles on a lx fiber based solution but will likely
require a skilled installer to setup that much cable for you.
Depending on your locale I am may be able to put connect you to a supplier.
Have you considered a wireless direct beam solution? Especially
considering the 'temporary' nature of this install.

Hello David,

Not directly FreeBSD related, but how much of a chance is there that
two
machines could communicate directly over 5,000 feet of cat5 with no
special hardware?
I do not know hoe much a feet is in meters but AFAIK arround 0,3 which
mean, you are talking about 1.5km or 1 mile ?
Yes, roughly a mile which is 5280 feet. Maybe less, but no more than a
mile. Won't really know until I get there and start running cable.
There are inexpensive FiberOptic Transponder (I am using a bunch of
it from Transmode for my CWDM 1GE and DWDM 10GE network)
The 100 Mbit Transponder cost arround 600 Euro (each) and for
your 5000 feets you need only an inexpensive FiberOptic cable.
EVEN the cheapes one would transfer 1 Gbit at this distance.
What I'm not (yet) seeing is a fiber optic transceiver listed with
matching fiber optic cable. The transceivers seem inexpensive vs the cost
of the cable.
Are there any particular range extenders you have used and would
recommend for making this task a sure thing on the first try?
Perhaps I should put an inexpensive ethernet switch at each junction
to serve as a regenerative repeater?
You have to use at least 3 Repeaters which NEED electricity. Do you
know this?
Yes, of course.
5000 feet CAT5, 3 Repeater plus electric installation cost more,
then the FiberOptic Cable with two Transponder. And of course, no
one can sniff traffic on FiberOptic and you have no worry about
magnetic fields disturbing your 5000 feet...
No one is going to sniff *this* one.
Am not finding sources of fiber optic cable as easily as I can find
fiber optic transceivers.
100baseT ethernet switches are about $25 each if one will serve as a
regenerative repeater.
Did I mention this is a temporary installation?
