I am not going to debate what the ultimate broadband system architecture
is too long because there really is no perfect solution. There are way
too many ways of doing things for us to debate it too much. I used to
be in the Cable Television industry. In my 10 years in that business I
saw several different architectures used to deploy cable television
networks. What I am proposing here is no more or less capable of being a
solid delivery platform than these other designs I saw in the past. It
is simply different.
There are more points of failure in what I am proposing than there is in
direct fiber runs. That does not mean it is a bad solution. It simply
means there are more possible points of failure. The impact of this
factor can be minimized if proper design methods are employed. There is
no mention here of how deep a cascade would go for these nodes of
millimeter wave. We could all get into the specifics of node count,
power backup, loop architecture, etc. but the long and short of it is
this. If radios are designed and built with low cost, low incidence of
failure and cascade counts are kept to a minimum then a very acceptable
and practical design can be built in a cost effective way to deliver a
triple play solution.
The ability to deploy an entire community-wide network with this design
in a timely fashion is probably the most attractive factor in this
proposed design. I am reasonably certain that a well trained crew could
setup an entire small town in just a few days. I really believe that in
time you will see millimeter wave radios used as a way of delivering
high bandwidth for multiple service offerings in WISP operations. Is it
"the" broadband architecture? I doubt it. I also doubt there is a
perfect architecture out there. Regardless I am certain what I am
proposing is very capable of being an effective platform for triple play
deployment. Until there are low-cost reliable CMOS based millimeter wave
radios this discussion is academic.

John,
I believe there is such a thing coming, and that it may fit in some
applications. But I can't see carrying data, VoIP and TVIP across a
wireless backbone that is all fed from the radio next to it. Unless
you are going to run a complete mesh type network (which would be hard
with radios that only reach a few hundred feet), then each radio is
dependant on the upstream radio. So to go around a neighborhood with
100 homes, you could be talking 20-30 radios, plus the WiMAX or Wifi
access points, etc.
You've heard the 12 days of Christmas song that says "One light goes
out they all go out", right? :)
We currently have a fully looped fiber ring around our city. We
currently have about 50 customer drops, and we run Cisco switches with
Spanning-Tree at 1gbps speeds. Even at this level, there are still
problems. Fiber outages, switches that fail, long term power outages
(8+ hours) at customer locations, etc.
People can handle the Internet being down for a few minutes or hours,
and VoIP a few minutes.... but TV is an entirely different thing.

The day is going to happen in the "not so distant" future when there
will be CMOS based 70 to 90 Ghz radios the size of a pack of smokes.
These will only effectively send data about a few hundred feet. These
radios will do over 1 Gbps from day one. The idea is to run them back
to back from street light pole to pole and have WiMAX, Wifi, 802.11a
(insert your favorite client platform radio here) as the client
access device to serve a few homes or businesses around the poles..
This gives us a platform for broadband, telephone and cable
television all over wireless. This is not a pipe dream. I am about 2
weeks from having my first pole agreement signed. It is going to happen.
The 70 Ghz gear is not going to be a long haul solution. It is going
to be a real nice high throughput short haul solution to compete for
triple play in cities and even smaller towns eventually. I plan to
help prove this as a viable broadband platform in my own community.
Now I just wish my friends at Intel would hurry up the development of
those CMOS radios! They have all the patents and prototypes today.
Bring on the GigE through the air!

Tom,
How do you think 70 ghz gear will cost pennies and help us? For a 1
mile ptp
link you need 4 ft dishes on each end, I cant imagine this working

ptp or ptmp ...

Bob made a good point regarding contracts.
Use the you can serve them today, to your advantage, and lock them
in. Charge install fees because you can, so yoour gear is paid for
by the time FIOS does come, and you are in the position to be your
most competitive.
My view is that it is a time stall situation. Wireless gear is
evolving. Its
jsut a matter of time before 70 Ghz GB gear can be had for pennies.
Maybe not this year, but sooner or later it will. When FIOS is a
real threat to Wireless, thats when the GB wireless manufacturers
will start to lower their
prices, because it is what they'll need to do to sell gear.
Make sure your antenna colocation agreements on every sub's building
allows for a second antenna, so when you can afford to go GB
broadband, you can do so without delay from landlords.
Verizon has been advertising FIOS hard in our markets to, but its
been over 6 month for some, since advertsied and no FIOS. FIOS is
expensive to buildout, and they need a certain number of pre-signed
up subscribers to do it. Its hard to convince people to get rif of
their satelite and cabled TV. There is security in not being locked
down to a signle provider for ALL services. I can see it now,
someone gets behind on their phone bill, and all
a sudden the TV gets turned off, the broadband gets turned off, and
the PHONE.
IF you wait until FIOS is installed and then try to compete you
won't be able to. The goal is to scoop up the clients before its
available.

Right. Unless there's a technology upgrade soon in the 2 / 5 gig
areas, we're going to
need something else to compete...
I have a 20 meg feed right now, and it's about 1.5 meg average...
But to no customers can
I deliver more than 10 meg to without a fortune in hardware

I can get a 100Mbps or 200Mbps feed today at very good pricing
(what I would pay for a T1 5 years ago :-)) but the problem I see it
is delivering 15+Mbps in a PtMP setup

And that's why having them sealed into a contract like Bob
believes in
protects you :)
Won't be long before YOU can get that feed (maybe from another
ISP) as
well and start feeding it into wireless shtuff

I agree, most sub's use about 1Mbps to 2Mbps if they very active
downloading content (ftp, streaming, and some p2p) (I limit p2p on my
system but allow some
bursts) other traffic is not limited
But when trying to sell a customer will go and say hey I can get
15Mbps from verizon for $50 and only XX from you

Seriously, how much does a sub use anyway? If you keep control over
p2p, how much are they really going to take anyway? Anyone got
numbers?

this pricing - the
15Mbps
for $49.95 a month seems like a really good deal and would be tough
to beat, currently I am using Nstream/MT which gives me about
20Mbps to the customer
Up to 5 Mbps/2 Mbps $34.95 - $39.95
Up to 15 Mbps/2 Mbps $44.95 - $49.95
Up to 30 Mbps/5 Mbps $179.95 - $199.95
