Since I've posted this weve been discussing it and the topic of 2.4 band itself came up. The concern is that the 2.4 band is already flooded with things such as phones, cameras, you name it.
Here is the response from Nomadio themselves...it refers to U.S FCC regs, answers that question.
I queried our technical lead and here's what he said:
We are not an "Amateur radio service", under part 97 of the FCC rules,
we are a "consumer ISM device" under part 18 of the FCC rules.
The Sensor uses a number of technologies to avoid interference with
other 2.4 GHz devices. The Sensor is smart enough to detect other
devices operating in the 2.4GHz range in same area, and move to other
parts of the band. It also sends signals multiple times on multiple
frequencies to make sure that they get through even if there is
interference. Finally unlike any other RC radio it uses special codes
in its messages so that other radio signals on the same frequency will
never be mistaken for a command to your car.
Which is to say that we have it covered
Here is some other questions that were asked and answered regarding this radio.
Since the vendor has responded to my message, I have a few questions of my own:
1. What about range? How does it compare to that of a normal FM radio?
2. When will we see versions for aeromodelling use?
3. Can a PC interface with the TX when it is on and send and receive signals? Could be very cool for amateur robotics.
4. Any chance of a webcam as a sensor or would that need too much bandwidth?
I'll answer your questions in order.
1 - if we used the big antenna that is on the prototype pictured in RCX photos, the range would be 1 mile. The real antenna is about 3 inches long and yields a usable range of 1/2 mile.
2- If we had a nickel for every flyer that came by the booth at RCX begging for Sensor/Aero, we'd be rich!. We chose to address surface vehicles first to establish our company in the market. For a variety of reasons Sensor's technology is really really interesting for flyers (for example it's expandable to support 16 servos at 12 bits (4096 steps) per servo - that's a lot of things to control! You could use one channel for 12 "on/off" things and still have 15 moving servos.) What we'll need to do is get Sensor/Surface shipping and happy and then we'll turn our attention to air vehicles. There are some issues to resolve with AMA and FCC since flying is much more potentially dangerous. That being said, the guys who fly $10K planes and have been hijacked by some kid in the pits turning on his radio are more than ready for new technology. The "Air Sensor" would definitely be a new case design with joysticks and probably a big screen like a PDA. And like crystal air radios, it would be more expensive. We were also a hit at the show with the robot wars guys because of the extra channels possible for death rays, neutron phasers, etc. <grin>.
3- I doubt that the code specifically supports that right now - we have designed the USB to capture the telemetry while you are driving. the good news is that it certainly could be done - it's only software. Unlike legacy RC radios, Sensor is software driven. We plan to provide a developer's kit and of course software updates, some free, and some with a charge if there is a lot of development involved.
4- We already do the cam thing for several of our military sentry platforms. At this point it takes too much horsepower to mpeg encode in the car so we use a separate analog video transmitter on the robot. This works acceptably well for the uses that the military wants but it's certainly not broadcast quality. There is glitching when you are moving around. Someday when digital video is cheap we'll be able to send it down the telemetry pipe but that's going to be a while.
5- the sensors look a lot like servo extensions - none of the sensors I've seen is larger than a dime and they are very light. As soon as we have approved product shots, I will post them here and on our web site.
