Um, I think I said to be ready to do that.
Also, what are ya gonna do when you get that fancy new omni in and find out
that the system is circularly polarized or uses such low gain antennas that
there is really little or no xpol isolation?
AND, if it's not dealt with in ways other than a forklift upgrade you'll
just have to roll over and wet on one's self when the next "big thing" is an
hpol version of the same system.
The biggest problem with trying to help in this case is the lack of real
data.
How far away from walmat are the customers?
What directions are they pointing?
Is another tower an option?
Sectorizing?
What is the eirp and polarity of the walmart system?
Are you SURE that there even is a walmart system?
The list goes on and on.
Several things need to happen at the same time to save the customer base.
And it never hurts to ask/try..... I try very hard not to make decisions
that take away anyone else's ability to be helpful.

Come on Marlon... even if all 100 customers went in and complained, the
manager at Walmart is going to say "You'll have to call corporate... there
is nothing I can do". Sending letters, going in person, etc. is not going
to do anything. Walmart doesn't care... they are doing $1 billion in sales
per day... PER DAY. Even if those 100 customers threaten to stop shopping
there, it wouldn't matter. Another 100 people from that community would
take their place in line (literally).
Fix your system and get the customers back online WHILE trying to get them
to fix their system... but don't wait for one or the other... here is what
I would do:
Order an h-pol omni Monday and have it shipped overnight.
Start changing customers Monday morning to h-pol. Should be able to do 20
per day per tech.
Contact an attorney and have a letter delivered to the Walmart manager
Monday afternoon.
Install the h-pol antenna Tuesday and continue switching customers.
Have another letter delivered to Walmart corporate. Realize that once it
hits their legal dept. you are probably 2-4 weeks for any type of a
response.
Credit customers for the downtime (pro-rated based on 30 days per month).
This just helps your PR.
Issue a press release to your local newspaper about the problem and how
you were able to respond so quickly and get the problem fixed, even when
Walmart did not want to cooperate.

I'm a big fan of trying to work things out.
In person if need be. Show up at the store and ask them if they can at
least try turning the power down etc. If they say they can't adjust it,
then they can always put in attenuators between the radio and antennas
they are using.
If they still won't talk to you send a few customers over to talk to the
manager.
Naturally, a good letter from a lawyer hitting them on tortuous
interference with a contract (no help on the interference side but there
are blocking access to customers issues involved here)....
The bad publicity idea is a really good one.
And, I'm not a fan of it, but catastrophic interference in the
neighborhood of their system is always an option. When companies are
jerks I'm not nearly as worried about putting 50 cordless phones across
the street and making a lot of phone calls. Baby monitors are good too.
I think you need to use baby monitors with directional antennas shooting
to a location on the other side of the store for a new security offering
you are thinking about! grin
We've already almost completely stopped shopping at wally world. Mostly
because the attitudes in the stores sucks. The employees are nice enough
but rarely smile and the rest of the customers are usually down right
rude.
In the end, they'll get theirs. What goes around comes around. Someone
will finally have had enough of their arrogant attitudes and things will
change. I know they are building stores all over the place, and they are
always packed. But someone somehow will find a way to give the pricing
with better customer service. Online shopping may also take off in a
bigger way sooner than later.
In the end though, you have to get those customers back online. I'd try
bigger cpe antennas (I'm guessing that their system isn't gonna be just
vertically polarized) first. Another tower site closer to the customers
might also be a very good solution as it'll help you deal with all forms
of interference as you move forward.
I'm guessing that they system isn't fhss as you should still be able to
talk to your customers, just at a slower speed. Have you pulled out a
spectrum analyzer and looked at what's really going on yet?
laters,

Thanks for the input .that is a possible solution but not one that could
be implemented quickly or easily.It would require a new Hpol omni about
$2200 a climb to install it and a trip to about 100 customers home to
change their eum antenna to h pol.This may be how it gets resolved but
really all we need to to do is have them turn the power down on their
equipment which only needs to reach 100 ft or the area of their loading
dock.or drop to a 5or 10 mhz channel that is not on our freq of 918.4.It
would be a simple problem to resolve if we could get any cooperation
from walmart.Any ideas on how how we could create interference to their
system to get their attention.I realize this is not the proper way to
resolve the problem but it might encourge them to be better rf neighbors
maybe.
Thanks

Hi,
You may want to try changing polarity and see if that helps. Often going
from vertical to horizontal will make a big difference.

Hello List We have an interference problem come up this week that we
have been unable to resolve.Hopefully someone here has some input on
how to resolve it.The problem is walmart installed a rfid scanning
system at there loading dock which instantly raised the noise floor at
our 900 mhz waverider access point by 20 db which killed about 30 of
our weakest links.this equipment is operating across the whole band so
there is no way to change channels and get away from it.The walmart
store manager says its not his problem and refuses to call the company
that installed it .I called the company which is adt security and they
refuse to do anything unless walmart request it.walmart home office
will not return my calls and the regional manager actually hung up on
me and will not take calls from us now.We have been very polite with
them upto this point and gave them no reason to act like jerks.Does
anyone have any suggestions on how to resolve this problem?
Thanks
