The POE outdoor is available as an accessory
which can be used with any existing smartbridges unit.

Hi Vasu,
Yes, but what about for the airBridge indoor units? Anything cheap and
reliable enough to be included for every customer?

Thank you for the information, we are working on the
firmware level as informed by Nish to resolve the disassociation issue.
The Poe
Outdoor is designed to exactly check the power supply at input and output side.

Some
diagnostic features are
·
Auto–sensing of cable length
·
Power requirement sensing for connected device
·
Detection of low Voltage supply
·
Low Load Resistance detection
·
Detection of Short Circuits
·
Detection of moisture in cable
Best
Regards,
Vasu

Nish,
Thanks for at least re-assuring me that you guys are looking into it!
I have a suspicion of what may be happening. I've noticed that those who
have this issue are also the same customers who have maybe one or two power
strips with every electronic product imaginable plugged into it. I see
this alot, but it doesn't seem to occur for everyone. Maybe some of these
customers keep the other electronics turned off, and everything is ok until
they start turning more things on? I know that if there is a
"brown-out" the radios may not associate or may dis-associate.
Many of these homes have old electrical wiring -the type without a proper
ground receptacle. With our APPOs, we had to have the management re-wire
the electricity in the basement office to provide proper ground. This
also seemed to help some of our equipment work consistently.
If you guys think this may be the problem (or "a" problem) perhaps SB
can provide a software tool that measures input power levels (hopefully without
needing to add hardware)? Or have a light on the powerShot to indicate
faulty power levels?
Kind regards,
Sevak

Sevak,
We have been trying to understand this “Occasional
Dis-association issue” for quite some time but it has been an illusive problem.
We have been unable to reproduce the problem, even after we brought units back
from the field that exhibited the problem. Below is what we know about it so
far and what we are trying to do. Hopefully this info may help in your
situation.
The symptoms are - at random intervals the airBridge will
loose association and will not regain. A simple power cycle, software reset or
just doing rescan will establish the connection. In a large majority of cases
we find that reverting to the setting of Long Pre-Amble (factory default) will
clear the problem. Many other times we find the combination of over powering
the RF side with Amp tends to create problem. And other extreme is that
installations with low RSSI and LQ values and not enough fade margins have this
problem too. We even had people report that just exchanging units from
subscriber A to subscriber B took care of the problem.
All this points to the instability due to RF and
interference related issues. In many cases it is possible to clear the problem.
Yet there are a few cases when these steps do not help. It appears that in
these instances, the re-associate will not happen till it is rebooted. And due
to the sporadic nature we have been unable to track down the root cause of it.
In order to provide some interim solution, we have developed
a software utility “simpleStatus” that acts as a watchdog timer and reset the
unit under certain conditions. This software is helping many users and you can
get a copy by writing into the support desk. This software is a slimmed down
version of the simpleMonitor without any configuration buttons and enough
dancing lights so you can give it to the subscribers without loosing control.
Our next step is to try to put the same code in the firmware.
As we have been doing the research to find the root cause,
interestingly we have learned that virtually EVERY manufacturer’s equipment
suffers from this symptom. We found similar user complaints, similar
manufacturer’s answers. Users coming up with their home brew solutions like
periodic pinging the devices, some even going as far as hardware gizmos that
would periodically power cycle the devices etc. I am sure all of these things
help in different cases and make the issue smaller and smaller. We are also
incorporating some of these items in our newer products to increase the
robustness. Some measures we understand and some measures are incorporated for
motherhood sake.
Hopefully someday we all will get to the bottom of this
unexplainable industry phenomenon.
Nish

I posted this problem earlier hoping that someone from sB would respond to my
question, but they didn't yet.
Would someone from sB tech support please tell me what is going on here?
Now, I have 3 customers who are having issues with the airBridges. One
day everything is ok, but a day or two later and they cannot get onto the
Internet at normal speeds. The speed is EXTREMELY slow and usually just
times out. 2 of these customers are within a few meters of the access
point and the 3rd is a block away. I've noticed that if I unplug the
airBridge and replug it back in, everything is ok again.
Since I don't want to keep going to customers' homes to unplug and replug
airBridges, will sB please help me out with this issue? My customers are
very vocal in their community and will spread bad news about our service if
this issue isn't resolved.
Thank you,
Sevak
