I think we are having a problem with terminology. What name best fits
which new technology?

First everything was EMF. Then wireless needed to be clarified with RF EMF.
Now the term EMR is becoming more used, as when the field sends out
waves for miles, is it still a field? Not really.
At the antenna, the waves are created with the same electricity that
when wound around a coil creates magnetic motors, but instead of a
steady amperage of electricity being drawn, it is chopped up into pulses
of on and off at a specific rate, or frequency. But that magnetic effect
is near-field, only really close to the emitting antenna.

So In this case, the Magnetic part of the name refers to the process of
creating the RF, and not inferring the magnetic field extends for miles.


As to the products you are inquiring about, I'll step back and let
somebody more experienced with them answer.
