Amen brother Tom! You have seen the light! The whole mesh node
bottleneck problem goes away if you have $90 millimeter-wave radios
acting as gigabit backhaul connections from node to node. That is just
one billion dollar application of this technology. Don't think this is
"pie in the sky" either. Millimeter-wave radios can be built using cheap
CMOS technology instead of the current SiGe. It is like the difference
between building out of rust instead of diamonds. Ken started talking up
low-cost gigabit radios a while back and few listened then. I thought he
had gotten hold of some bad drugs till I met the millimeter-wave
manufacturers that Ken hooked me up with at the IWPC. I saw the light
then. I thought the manufacturers saw the light too when I talked about
the day of millions of cheap millimeter wave radio modules being used
everywhere to provide multi-gigabit connectivity at low cost. Sadly they
thought I had gotten hold of bad drugs I think. All but one guy from
Intel. He has gone way underground now though. I signed a NDA with him
so I cannot say much beyond this. Trust me though when I say that
low-cost GigE radios can and will be built someday. I just hope it
happens before we all fall behind the technology curve. Cable and DSL
will be selling 10 megs for $20 per month in a year. Can you all
compete? I certainly wish someone would wise up and start churning out
those low-cost dumb millimeter-wave modules. Give us a low-cost mini-pci
millimeter-wave radio module and we will change the world forever.

I'm a big fan of the potential of GB fiber.
But I disagree with your comment.
There is a small percentage of jobs that are worth paying the $40K,
and thats where the vendor makes his sale, today.
But that mentality is holding the industry back. They can make it
cheaper and sell it cheaper if they wanted to.
And quite frankly I can care less about the 1% of the market that they
fit the mold to.
I care about the other 99% of the market, that would allow WISPS to
compete and beat cable and DSL companies to all Americans.
GB is not destined for just a fiber carriers temporary last mile
connection. IT has the potential to be the Fiber replacement altogeather.
Wireless manufacturers that do not see this are blind as a bat. There
product should be priced to sell for ANY application.
Mark my words that GB wireless will not stay at the price its at today
for long. If it does, new vendors will surface to replace the vendors
that are slow to meet the market demand, which is GB everywhere.
Thats not going to happen at $40K a link.

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
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

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
