Remote controlled Avatar question.

[SnowRider]

My biggest problem with the idea of the Avatar link being radio waves or some other EM transmission is this:

Where's the "receiver" located in the Avatar?

I.e., if it is radio waves or some other EM transmission, then there would by necessity have to be some kind of antenna or something made of metal in the Avatar such that the signal could be received and then "decoded" by the Avatar's brain.

So what, they put a very, very thin wire coiled up in the Avatar's body somewhere?

I don't think so. If there was anything made of metal in the Avatar, that object would have been subject to all kinds of eddy currents, interference, etc. from the magnetic fields and/or would have been fried or otherwise destroyed by those same magnetic fields.

You can bet that whatever method used for the Avatar drivers to link up with their Avatars isn't radio or other EM transmission.

You can't have the Avatar suddenly fall over if the transmission starts getting interference, enters the radio shadow of a mountain, etc. because that would be very, very dangerous to both the Avatar and the driver.

Whatever it is, the link method is secure, instantaneous, and immune from any kind of interference from magnetic fields or anything else that might disrupt or otherwise weaken the signal.
