This is a little out of the teensy arena (well not really), but I'm trying to understand why R/C stuff (ie helicoptors) need so many RF channels.
If I understand it correctly, each channel is a sliver of frequency range for communicating. And each channel is used to control one particular component (ie motor, servo, etc).
Why would things be designed like this? Isn't there plenty of bandwidth in a single channel to send all the commands for all the components. Maybe I completely misunderstand the issue. Trying to read up, but still not very clear to me.
And, can these RF chips being discussed on here (RF22, RM69, etc) do a single channel, or can they do multiple channels simultaneously?
Thanks.
