All ISM- Wifi bands do have licensed operations. The 2.4GHz is licensed by many phone companies giving them commercial rights.
Our radio's are licenced to use certain channels. Most industrial, scientific and medical do use and have the monopoly over the 2.4GHz ISM system. Once RC radios start causing issues with any of them for instance by the way of interference, who do you think will be the first to go?
"802.11 technology has its origins in a 1985 ruling by the US Federal Communications Commission that released the ISM band for unlicensed use.[19] In 1991 NCR Corporation with AT&T invented the precursor to 802.11 intended for use in cashier systems. The first wireless products were under the name WaveLAN."
The industrial, scientific and medical (ISM) radio bands are radio bands (portions of the radio spectrum) reserved internationally for the use of radio frequency (RF) energy for industrial, scientific and medical purposes other than communications.[1] Examples of applications in these bands include radio-frequency process heating, microwave ovens, and medical diathermy machines. The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequency, so these devices were limited to certain bands of frequencies. In general, communications equipment operating in these bands must tolerate any interference generated by ISM equipment, and users have no regulatory protection from ISM device operation.
Despite the intent of the original allocation, in recent years the fastest-growing uses of these bands have been for short-range, low power communications systems. Cordless phones, Bluetooth devices, and wireless computer networks all use the ISM bands.
You can doubt all you want and you can think I'm short on fact and long on anecdote all you want. I don't twist the facts nor am I on a agenda other than to deliver the facts. Your counteraction reads as if it's coming from a pessimist more than knowlege.
The phone companies are just a small pea in the pod who are under license to use ISM. I am saying companies pertaining and not to the phone companies use ISM, and if any want to use the bands our hobby is now using, and if or when the new RC radios starts to interfere, the AMA will be told that they can no longer operate under the ISM Band. The phone companies do have clout and influence with the FCC. Anyone who worked for the phone company knows that.
The AMA is concerned of this, and told me as such in a different way.

So in one instance the AMA is concerned about interference, ok, I get it. Then why is the AMA making a big deal about the "fly at work" deal? I find it a lot better chance to run into things like microwaves, cordless phones, wireless networks/devices and bluetooth at work than at my local flying fields. However those that fly in more densely populated areas may run into more of that kind of stuff than I do. Hopefully the folks at the AMA/Muncie remember to turn off the wi-fi during Nats next year!
Has there ever been any documented loss of signal or interference of these devices CAUSED by a RC Tx? Where there dropped calls at Joe Nall at the same time the models crashed? Should I expect the next guy to put a model in the beans/corn/woods turn back to me and demand compensation because I was uploading photos to a photobucket account using my iphone?
And finally, why so hush-hush? The AMA will tell a guy, but hold him to secrecy, and then make a few backhanded comments at the very end of a magazine, no verifiable outside evidence. As long as I have the little FCC sticker on my TX, I'm flying
