Tom,
$40K is a lot, true.
But here's what I've heard from fiber providers in my area:
in rural areas and in existing developments it's very expensive to
dig, trench, pull cover, and pay all the other fees fiber providers have.
In these cases, Gbit wireless is a point to point link for the last
mile.
I think that's where the economies of the wireless fiber solution
begin to appeal to them.

The second we get 70-80Ghz down under $15,000, it will start to get

I've ran into very few places that Fiber can't be run less than 1/2
mile cheaper than buying GB wireless.
The only real sale strategy for GB at its existing cost, is Speed of
Install. For those who can't afford the 3-6 months to organize
getting their fiber pulled.
Now the second you can Span over 3 mile reliably, which 70-80Ghz can
do, it gets more exciting. But at $40 grand, thats a tough sale, in
Tier1 markets.
At $500 a month for fiber, thats a 6 year ROI on the GB wireless gear.
The advantage of Pencil Beam GB products is that a lot of links can be
simultaneously deployed in an area. Making it so expensive takes away
the abilty to use the technology to its potential, and used for the
rare backhaul link.
GB wireless should be being used for mass deployment of PTP in Urban
America. For that, it needs a price point under $10 grand, in my mind.

Licensed 70 to 80 GHz actually has less oxygen absorption of the
signal than 60 GHz (by several orders of magnitude). If you are
providing a Service Level Agreement with 5 - 9's or better % uptime
then you should stick with a licensed product IMO. As Matt states
below, both companies offer a licensed product. Depending on the
rainfall annually where you are deploying you may get nearly the same
uptime in 60 GHz, especially since it is just 0.4 miles. I would
research before making a choice though if uptime requirements are
strict.
Remember to make sure you research your connection into the network
also. Your point of demarcation will need to be identified. In many
cases it is a port from the switch that you would provide. Make sure
you select a switch compatible with the radio product you launch. If
they provide the switch demarc point then make sure it is on the list
of tested and known good hardware for connecting to the link you setup.
Before quoting the product make sure you remember things like back-up
power, downlead selection, surge and lightning suppression, stand-by
spare radios for replacement, etc. Ask to see the software management
interfaces for the radios being considered. If you buy radios that
work but you cannot diagnose what is wrong when they break then you
have a problem. It is not like you will have a 60 to 90 GHz signal
meter or spectrum analyzer anytime soon so the software management
interface is very important. If you do not address these things now
then you will be sorry later.
If I were you I would at least get a quote or two from fiber
construction companies to see if a fiber could be built for same or
less money. Depending on the location this might be the more
efficient solution.
That is the biggest beef I have with the millimeter-wave crowd right
now. They try to think in terms of how much money they can squeeze
out for each single link sale instead of looking at the mass
potential if we could all get our hands on low-cost Gigabit backhaul
to all of our towers. Ken and I have been beating this into their
brains now for a couple of years. It will sink in someday when they
think it is their idea. :-) jk

This is a new area of wireless deployment for me:
I've been asked to quote for a gigabit wireless link between a
radiology department and a nearby hospital (0.4 miles).
I'm aware of two options so far, and here's some info I've gathered:
-- BridgeWave - 60Ghz; unlicensed; $25,000 complete link;
~$6,000 5-year hardware warranty; 1Gbps
-- GigaBeam - 70/80Ghz; licensed; $37,000 complete link
(includes $1,000 10-year license); $0.00 5-year hardware warranty;
2.7Gbps release by Dec. 2006.
I know Bob Moldashel said he has installed the Bridgewave.
Anyone care to comment on any experience you've had with these
companies?
Thanks a lot.
Mario
