Lightning is by far the largest threat to our WISP. It would be interesting
to know the typical CPE failure rate (due to lightning) experienced by
WISP's. I know that we'll replace 10% (+/- 5%) this year due to lightning.
We use the $30 Citel brand Cat5 surge protectors on both ends of the
I have a friend that is a tech for VZ and goes around replacing cell
gear hit by lightning. Even with the protection that VZ puts on their
equipment, grounding, surge arrestors, etc., let's just say he gets a
lot of overtime during the summer. ;-) No matter what you do to try to
Actually, I've been fairly lucky. The only lightning losses I've had were
on my tower. I've got one CPE that may have been taken out by lightning,
but it came through the house and blew a LOT of other stuff as well. To me,
to add $30 per install doesn't make sense when I've only lost 1
I lost 15% of my CPE's one year. It was a dry Summer (I theorize the earth was not conducting well), then we had a couple of bad storms. Using a $1.50 inductor on the Ethernet cable near the radios really seems to have helped a lot.

On thing I forgot to mention is that every single packet transmitted is
going to be retransmitted on all the WDS/AP connected together on the
wireless side. With sustained traffic that would mean that all of them
are transmitting and receiving the 2 megs mentioned. And we can assume
Can you share some info on the $1.50 inductor you reference below?
Do you then ground the inductor to the mounting arm which is then
grounded to an earth ground? Please share if you don't mind, inquiring
minds would LOVE to know. ;-)

We pay $10 - $30 to a sub-contractor to do a site survey and
we usually have 5 - 10 of them a week. This has been an expense
we've absorbed but starting in the next few days, we will be
passing this fee along to the person requesting the site survey.
If their site survey is successful and they
I use the 240-2318-ND (towards the bottom of the page). Just wrap the Ethernet cable through it as many times as possible. You have to purchase 100 to get that low, low price I mentioned :-). We are located in Ohio.
We stopped doing site surveys almost 4 years ago. We were spending way
too much time and having to send someone to the location twice seemed
like a waste. (some of our coverage area is a 2 hour drive each way)
We now have coverage maps and tell people we no longer do site surveys.

How do you figure? Crown Castle is a nightmare to work with, and Global
Signal has worked well with WISPS. I hope Crown Castle takes Global Signal's
good sense with the purchase.

Contrary to popular belief, lightning likes to follow the path of least inductance. Inductance is the resistance to a change in current flow. All I can say is that they have worked for me.

Exactly. Crown is a nightmare if you are not a carrier, and
they are doing the assimiliation.
Smaller tower owners will continue to cater to the smaller
companies, the WISPS, and continue to gain their business.

It seems we (people on this list) are always easily dismissed by
large tower owners. These dismissals are often in the form of here,
pay this $! fee up front to deal with us or who are you again?
or my favorite and one that was told to me by an American Tower Rep:
we don't deal with
The problem is that cell carriers (at least in my area) pay $500 -
$2,000 per month to be on a tower... the same towers that I pay $100 -
$250 per month. If you owned the towers, which customer would _you_
rather have? :(

The conglomerate tower owners know that there are only so many broadband
(cellular) carriers to go around.
The prices will drop for the WISPs as soon as the broadband business runs
out! Cellular buildout cannot go on forever.
There are plenty of independent tower owners who will welcome the WISP
I can't even get a ballpark price on some of their towers. I would like to
know if I am wasting my time (and theirs). I have 3 towers in mind I would
like to get on of theirs.
