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

We deploy BrideWave gear and have been happy with it. BridgeWave also has

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
