Thanks Steve / Robert<br>
<br>
And everyone who has responded directly It would seem that they are
using Motorola Canopy 800 system.<br>
<br>
In Rio Rancho our company did a bunch of tests with various 802.11
variants and even up to 802.20 Wi-max ( also FOS laser ) and we found
some really curious issues with wireless up here in this part of NM
such as<br>
<br>
1. The faux adobe coatings on the majority of homes had chicken wire
over the drywall and exterior coating to bond the plaster. This created
a de facto Faraday cage effect and necessitated the use of a receptor
booster amplifier as the only means of signal stability ( Best place
for signal input device was on the roof structure about 4 feet above
the roof clearing the up stand wall ) Attempts to use these buildings
as reflectors ( Pool table type ) also fails for similar reasons. (
Different building structures perform better but you have to know that
in advance ) <br>
<br>
2. Line of site target accuracy issues and echoing was prevalent on all
wireless systems except FOS with huge loss of signal ( The signal bends
and warps in atmospheric changes ) <br>
<br>
3. Weather related issues ( also seasonal ) affected all systems and
deteriorated service by some 40 - 60%<br>
<br>
4. No company at that time had run pre service due diligence ( In all
seasons ) and none had mapped good / average / poor service areas (
Azulstar only tested the signal to truck mounted antennas with good
line of site to the service transmitter no more than 1 mile from the
central site and not to the customers service point - hence they went
out of business when it did not work ) <br>
<br>
5. No system could demonstrate good symmetrical performance average was
( performance quoted to actual = Down 60% --- Up 20 - 30% )<br>
<br>
6. Security issues were noted on all systems and interception of both
down and up was fairly easy with open source products<br>
<br>
7. Multiple issues where noted with signal interference between
especially around electrical power high voltage transmission lines (
this rocketed in winter rain and adverse weather conditions and it
would seem that the magnetic field of the lines shifts in bad weather
and even sunspot type phases ) <br>
<br>
All the above basically means that the field crews that support
wireless must be constantly adjusting the system parameters to make it
work an expensive proposition.<br>
<br>
The added point is that once the issues are understood you can boost
the service in huge ways ( Including compression bursts and bit torrent
type support ) especially if you are using the system to monitor the
system and set realistic goals and know the type of service that the
customer really wants.<br>
<br>
Curious to get comments and further feedback<br>

I'm on a similar Motorola 600Mhz System run by the San Ildefonso
corporation Tewacom.com and have a similar experience (paying
$60/month). My service varies from 0-1.5M with ~.3M typical. I get
almost total dropouts for minutes at a time. They continue to insist
that my service is symmetric but it is rare that I get more than 50% of
download on upload. I use: <a moz-do-not-send="true"
class="moz-txt-link-freetext" href="http://speakeasy.net/speedtest/">http://speakeasy.net/speedtest/</a>
most of
the time.<br>
<br>
If there is something inherently limited in these systems, I'd like to
understand it. I don't like pestering people trying to do their job
(TewaCom or Grappa) but I also like getting consistent, expected
performance.<br>

winter they ended up giving everyone a rebate on one month's fee,
though personally I'd have rather have the up-time than the cash.</blockquote>
I'm one mile from the TewaCom Xmitter and I get little if any
weather-related problems, but do seem to find dropouts and I seem to
need to reboot the 600Mhz modem somewhere between several times over a
few days to only once in a month.

I switched from 1.5M (nominally down) Satellite WildBlue (56k up) which
was *never* down but averaged .5M down and .05 up with lots of lag.
WildBlue also had monthly quotas (not sliding) which did not support
iTunes-class downloads on a regular basis.<br>
<br>
Previously I was on dialup which I rarely got higher than 28K
connection with effective speeds of maybe 50% of that.<br>
<br>
I think Wireless on this scale makes most sense only when there are no
other choices. If DSL or Cable come available, I think they are a
better answer.<br>
