This, to me, is why this request is so unusual. This is much more suited for spread spectrum, secure, short wavelength (smaller antennas) and the like, and its surprising that Thales - a world renowned avionics corporation - is behind the push. It's also why I think this big 2m band scare is moot; someone didn't actually do the engineering, it's like they just threw out a random number and put it in a powerpoint slide.
