The company kinda has to do the certs as I understand it.
There is data needed that we won't generally have.
AND, it's fairly expensive. If WE certify their gear, will WE get paid for
the certification?
We, as wisps, just need to do a better job of demanding that people buy
certified systems. Part of the reason that I don't use MT ap's is the
certification issue. I *may* or may not use them if certified, but until
they are certified I'll not likely even try. When most people have that
attitude we'll see a lot of our favorite toys certified.

Subject: RE: [WISPA] Understanding STAROS with High Power cards.
I don't seem much discussions about integrators or wisps going to the
FCC to get these parts certified into a system. So, is it safe to safe
that most microtik installs are NOT certified and are therefore not
legal?
Seems to me like this would be a big issue for us all to address??????

do these all qualify as 'certified"

Parts dont get certified, systems do.
They have the capabilty to be certified.
Depends if the integrator took the time and money to get them certified.
Depends if the WISP took the care to buy them from an integrator that
certified them.

Since we have been on the subject- do these all qualify as 'certified"

yourself and stay legal...

Subject: Re: [WISPA] Understanding STAROS with High Power cards.
Our driver sets the output power using an electronics "volume control"
that is in the Atheros power out section. All drivers set the power
using that control. The precise setting is in tables provided by
Atheros for the various air rates and as you note it goes down as the
rate goes up. This is to keep the amplifier from being over driven by
the extra carriers that happen as a result of higher rates.
The high power cards that we have tested all have a power amplifier
after the Atheros power measurement sections, so the power setting
that the driver applies is further added to by the extra amplifier.
We have no knowledge about the specs of that extra amplifer except
that it supplies from 6 to 8 dB more power.

Can someone tell me how STAROS works in regards to setting power
levels to
cards that adapative modulate.
Specifically related to Cards with on board AMPs. To be more
clear....
A SR2 may be speced at 26db at 1-24 mbps, but 24db at 36mbps, and
22db
at
48-56mb.
My unconfirmed understanding is, that the SR2 adds about 8db via an
onboard
external amp beyond what the card is actually set to.
So if the card is set to 16db, it will have an output power of 24db
in
theory. However, its not that simple because the output power will
change
based on modulation.
Does STAROS drivers set the power as the constant power regardless of
what
modulation? Or does it set the TOP power? Does the power on the card
only
change if modulation drops and the power is set higher than power it
suppoed
to drop to? The radio card has no knowledge of what DB antenna is
connected
to it. And are the onboard AMPs a set output or variable output AMP?
The
point that I'm making is, how can we set the card to near MAX levels,
but
guarantee that they will never transmit above the allowed EIRP? If I
have
the conclusive answer to that question, then I can reduce the power
to
the
lowest level needed for a good link, with headroom capabilty if
emergencies
occur, but more importantly, I can document what the top allowable
setting
should be for that specific configuration of a radio, so when an
emergencies
occurs, my novice staff does not break the rules inadvertently.
It gets more confusing with multiple manufacturer AMPs. Because we
need to
have knowledge of what type of AMP is added to the card. (variable or
not).
And also what input power level its expecting to minimize internal
distortion. I can give an example of a test I ran yesterday using a
SR2
(400mw) and a Teletronic 22db (approx 150mw) High Power card. I
thought the
chipsets were near the same. I got really weird results. The AP had
an SR2.
THe radios were hard set at 24mbps for testing. At the SU we tried
using
both a SR2 and Teletronics. The SR2 had 10db lower signal at the AP
than
SU, unexplained. The Teletronics had 5 db lower signal at the SU
than
AP.
The SR2 had 15 db higher SU gain than the Teletronics SU, at MAX
power
setting. Now I'm assuming that the SR2 was heavilly being overpowered
during
the short brief test, and we set it down to 16db power in STAROS.
Why
did
this occured differently for the Teleronics Atheros? Is there onboard
AMP a
different type than the SR2? Or less filtering? Or worse sensitivity?
The
power levels also varied significantly based on what level cloaking
used, so
we were concerned on whether both cards, equaly cloaked. There was
some talk
in the past where some Atheros revs, only did 5Mhz transmits but
still
listened to 20Mhz during receives.
(We possibly needed significant power because we were blasting
through
some
trees and it was high noise environment, and we were using 30deg
antennas.
Before we get slammed for overpowering but within legal limits, Take
note,
that this is an experimental environment, to learn the product and
the
performance of high power cards. Its likely we could have done the
link
without high powered cards, but then we would not have been able to
learn
anything. We are also proving the viabilty of whether it hurts to
have a
HighPower card by default, and if the card still performs optimally
if
the
power is turned down. Or if the AMP in line causes significant
in-line
distortion that is disadvantageous for low power operation.).
I know there are two easy solutions...
1) Use a CM9 without an AMP, and avoid the problem.
2) Use a High quality OFDM Radio Like an Alvarion (Which we do often)
But for the sake of this thread, please ignore those two Options, as
the
purpose of the thread is to understand the specifications of STAROS
and
HighPowered Cards.
I think these kinds of questions are impairative for us to
conclusively have
the answers to, and not just have a "I think" thats how it works. The
question that I'm also posing is, can this gear be certifiable with
the
current StarOS feature set? Meaning, if there is no place to add the
DBi of
attached antenna, or the radio itself would not be able to auto-set
these
levels and left up to the engineer.
I'm going to Email Teletronics and Ubiquiti on the design specs of
their
cards, but I'm sure a lot of this depends on drivers as well.
Also as a disclaimer, we wanted to rule our power supplies and
Mainboard
hardware as causes. At the CPE, we used both a WAR2 boards and a
WRAP1E.
With the WAR board we tried using a 18V 1amp Power Supply, a 24v
unregulated
power supply, and a regulated 24V 1amp power supply. With the WRAP we
only
tried using the 18V, so not to blow it up (21volt Max spec). The
only
thing
left that we have to do, is ro replace the CPE SR2 with a different
SR2 to
make sure it is function properly, to confirm that it is the RF
environment
causing the 10 db drop in signal in one directions. However, I'm
guestimating that changing the card will have no effect. Based on the
AP
receive levels that are with in a db or two from each other comparing
to the
Teletronic.
