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!

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
