If their signal occupies the whole band it is probably FHSS in nature.
So changing to a 5 or 10 Mhz. channel will not be possible. Also, it
may not be possible to turn down the power. So it may not be that simple.
A certified letter from an attorney is probably more in order.
Unfortunately using unlicensed spectrum does not leave you with much
recourse. This has been discussed over and over on these lists but the
final outcome is always that you are taking a risk using Part 15 spectrum.
Good luck in your battle.

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
