Others are saying this is the RC industry trying to get us to buy even more radios.  I don't see how a frequency can be archaic, it is either that frequency or this frequency.  Did you mean the existing narrow band system?  Nobody is proposing that.  I think the idea is to get a band wide enough for spread spectrum.  I do not think it has to be as wide as the 2.4 Ghz band.  That is wide enough for computer networks and that is a lot more data than a 12 channel radio with telementry.  I also don't understand why two way telementry systems won't work since they have used more complex data systems on much lower frequencies.
