The choice to step into the elevator is yours - the accidental attenuation of 20 dB by "improper holding" of a device isn't. In engineering world, 3 dB difference is big, you figure out or talk to RF engineers what they they think of 20 dB. You must be kidding, right?

It's not as if it's like a PIN and you just request that a new one is sent out... Interesting thought.

Does this technology require frequent (i.e, annual) reauthorization, or something different?
