I'm not sure on the laws regarding 2.4Ghz in the USA but the smaller wireless video cameras I use are very low powered, way under 1 watt. I have seen some at our field that are 1 watt and we fly Spektrum systems with that thing going with no issues. Its on a glider and the guy flies it with video goggles so he gets a real feeling of being inside the thing. Never has caused a problem so far.

As for the systems having to hop I know thats not the case here. Baby monitors, wireless door phone video etc all use a fixed channel. Some higher end ones allow you to select from three or four channels or on some you have four cameras running and it switches every few seconds. Hopping with smaller cheaper electronics is pretty much unheard of.

However most of these smaller wireless vids do not use up all the band width on the channel. The easy way to explain it is 2.4 has a channel more like a 3D box than a flat line. That box can be seperated up into smaller squares that will theoretically allow up to ten devices to work at peace with each other on the same channel.

Thats how XPS can claim to be able to run 90 radios concurrently. FASST say they can run some enormous number and SPEKTRUM say 40. What ever the number, it really is irrelevant because your not going to get 40 planes or helis in the same airspace with out a lot of control from the CD. Plus I am sure there would be some serious latency as units clashed with each other looking for a gap to send packets of information.

As for XPS claiming to have the only system with Bi Directional capability my understanding is the others have that turned off as they dont want it or need it yet. Sure thing later on you will have your onboard info recorded on your radio and you can download it to your PC at night. Those things are not rocket science to include for either FASST or SPEKTRUM. They just choose not to do it for the time being I am sure.

I have some new software that I hope is going to show the depth or band width usage for each channel. Its pretty technical to make it understandable (for me that is) but if I can get the moons to line up again I will try to do some work tomorrow for you guys and post it.

You know guys something I am not worried about is being proved wrong if anyone can counter what I am doing. This is my hobby, learning by pushing my boundaries of knowledge is rewarding and enjoyable. So dont be shy to fire away if you have proof that shows otherwise. I'm not here for the fight, but I am sure here for the fun.
