Sorry, you haven't paid your spectrum use tax.
Turn that off.... CRASH! The government will
be paid one way or the other, spectrum auctions
are ok.
Oh, wait.. we already have open spectrum!
If you look at the regulations in 47CFR15
there are nice chunks of specturm set aside.
In fact it's more interested in where emissions
should not be in order to protect various
services. It also mandates field strength
limits which is a GOOD thing.
Section 15.247 sets aside the bands 902-928 MHz,
2400-2483.5 MHz, and 5725-5850 MHz. With No
fees or licenses required although certification
isn't cheap. That's a lot of spectrum to play in.
If the manufacturers insist on jamming everything
into the 2.4Ghz band, so it's crowded, then don't
buy more 2.4Ghz devices. These devices are
cheapest because that's where all the sales
volume is, the technology was a driver but it's
not anymore.
The trend is towards more chunks being allocated
for wireless devices. I really don't see a
problem here, why change?
