Me too.

453 is the Tx (outbound) side of the most popular UHF Land Mobile Public 
Safety band, in use everywhere, with portables likely to be in any 
building anywhere.  I'd have chosen 455 - 460, the mobile side.

That's always true, but who cares?  If you read this NPRM carefully, its 
language is careless, with mistakes of commission (pun intended) and 
omission throughout.  Bullet-proof they may claim, but if something 
might happen (or fail to happen) to a passenger's implant upon keying up 
a 50 watt mobile or base station console, I'd like to know about it 
*before* it's approved.  I'd bet no one looked at the Tx densities of 
these bands in any detail.  These days they expect us to do it for them, 
well OK you asked for it.

There should have been far more detail on the technology so I wouldn't 
have to speculate.  And where was this an NOI?  I must have missed that.

Trust but verify,
