Imagine a WalWart store going in across the block from a ham station
running EME on 2.4 Gig. I wonder what a strong discrete carrier would
do the integrity of the RFID system. They would certainly need to be
far better than the end user WiFi stuff being sold.

I imagine it would get you a visit from the FCC. Does the phrase
"deliberate interference" have any meaning to you?

We hams have enough bad PR problems without jerks like you getting on
the evening news.

Except the Ham Station is a "Licensed Radio Service", which has Priority
over any unlicensed system for the purposes of "Interference Problems",
on ANY Frequency. Mr. WalWart wouldn't get two steps with the local FCC
as his is an unlicensed or Part15 operation, and is specifically subject
to, and must "accept" interference from a Licensed Radio Service, and
must not cause interference to any Licensed Radio Service using the same
frequency.

Me been there, Inspected that, shut down the unlicensed operation
had the "Big Shot" complain to HQ..... got him NOWHERE....

Oh, you poor child.

One does not f**k with WalMart when it comes to interfering with their
inventory and checkout system.

We'll come visit you as often as we can. :-)

WallMart has to comply with the FCC Rules and Regulations, just like
every other company in the USA. RFID or whatever makes no difference.
If you think otherwise, show where the FCC has done other than
enforce it's Rules on commercial, noncommercial, or unlicensed
operations. RFID is an unlicensed or Part15 Service, and therefor
MUST comply with the requirments of Part15, if it is used inside
the USA. As the rules stand today, this means that the RFID System
MUST accept interference from ANY Licensed Radio Service, and MUST
NOT cause unreasonable interference with ANY Licensed Radio Service.
If such an interference complaint from a Licensed Radio Service
Station was received by the FCC and it was subsquently investigated, the
Investigating Engineer or Inspector would, site the Part15 Rules
to the interfering source, work with them to eliminate the interference
and if not successful, require the interfering source to cease
operation untill such time that the interference was eliminated
during operation, at the Licensed Radio Service Station. It wouldn't
matter if it was US Steel, WallMart, or IBM, the rules and enforcement
would be the same. Rules are rules, and the Rule of Law is what stands
here in the USA, and it applies to everyone, equally, Big Shot of little
guy........

Me if you can afford the airfare, come on down............

Well, if the moon wasn't up they could get you for intentional interference.

Now if you had a 2.4 GHz propagation beacon...
