Hello. I'm building a house in rural area with limited options for
Internet connectivity. DirectTV-based Internet is not an option with
the lag

Direct tv is not the only sat option. And besides for voip the sat delay
should not be an issue.

Isn't any sat solution going to incur a delay up, down, back up, back
down.

Usually one hop.

I have an avg delay of 644 to google, over my sat hop.
Using IP accelerators would help for voip. I get voip calls to work, but
sometimes the delay is worse than other times. But when you live in Rural
Alaska, you have to make do with what is available


I found DirectTV a year or so back was only useful for Web and
email. You couldn't do anything that required a constant stream.


Again, there are other sat providers. I myself would not have used direct tv

and Verizon's EV-DO Wireless Internet Access user agreement
renders it useless.

Seems alot of people do not see it like that.
What are you planning to do with this connection.

Serve. You can't serve anything, or doing anything beyond web and
email on Verizon's EV-DO.

Do they offer anykind of business plans. Most providers would not like
residential service to be used as a server type application.
Unless you agreed to pay more

"MAY NOT be used for any other purpose. Examples of prohibited uses
include, without limitation, the following: (i) continuous uploading,
downloading, or streaming of audio or video programming or games; (ii)
server devices or host computer applications, including, but not
limited to, Web camera posts or broadcasts, automatic data feeds,
automated machine to-machine connections or peer-to-peer (P2P) file-
sharing; or (iii) as a substitute or backup for private lines or
dedicated data connections. This means, by way of example only, that
checking email, surfing the Internet, downloading legally acquired
songs, and/or visiting corporate intranets is permitted, but
downloading movies using P2P file-sharing services and/or redirecting
television programming content for viewing on laptops is prohibited. A
person engaged in prohibited uses continuously for one hour could
typically use 100 to 200 MB, or, if engaged in prohibited uses for 10
hours a day, 7 days a week, could use more than 5 GB in a month."

So, its all but a useless service in my mind. I'm a software
engineer, who commutes into the city... I need Internet for my job.

Ok, see if they have business plans, and see if you can write it off as a
business expense



Which one. American and crown are both good companies.


Think it was Crown.

When I worked in the lower 48, we had a bunch of sites on crown towers.
Very good company, you should not have a problem with them.


You need to look at the frensel clearance here. Depending on your
frequency
you may have to go higher.
Being that the tower is at 14agl, and you are at 21, and you are limited
to
the lower rungs, I would try to get as high on the tower as you are
allowed,
say 20 to 30 feet, 40 feet would be better.


Okay, fresnel clearance. Good information. This one word had led me
to a wealth of
information:
line of sight (LOS) coverage, non line of sight (NLOS) coverage, et
cetera... LOS needs most of the Fresnel zone, et cetera. I would
suppose I would need to focus on a NLOS system.

Newer systems tend to use OFDM which does not require pure line of sight.
So if you find a system with OFDM, you should be ok.
And even at the range you are talking, a LOS system would probably work,
especially if you can get to place your antenna at say 40 to 50 feet on the
tower. You man not get 54Mbps, it may drop to around 11Mbps.


You may want to contact a local radio shop, or an IT shop.

Hmm, I was thinking of MAKE'ing this (designing, installing the ground
equipment) myself, instead of paying for it....

Look up "Wimax", "Wireless Bridge", Microwave point to point.

Look up Tranzeo on Google
as well as digitalpath for some decent priced equipment doing what you want
to do.
