I can't disagree. It will be a monumental undertaking, and
it is fraught with issues, but it CAN be done.
Software defined radios, as Jack Unger pointed out, is part
of the fix. We are not completelly there yet - but there is
progress being made.
The millions upon millions of wireless devices out there will
also need to be replaced.
As an aside, one of the reasons I am totally opposed to the
CyrenCall proposal is the use of propietary equipment. Any
use of the 700 Mhz band needs to be in NON-propietary
equipment. Make it easy, simple, and cheap.

Subject: Re: [WISPA] Public Safety
I wish that we could get all interests (including WISPs, Cellcos,
Two-way, Hams and Public Service) to think in terms of reservation of
air time as opposed to exclusivity of bandspace for future spectrum
allocations. If an emergency occurs then public safety should be able to
force a reservation of airtime in any band they need in my opinion. Then
everyone can benefit from having lower-cost, mass-produced equipment
which is able to be used by any interests in a given band.
I am not suggesting that we should not dedicate some bandspace for
public safety exclusively. They need some. What I am saying though is
that many other bands could have the ability to reserve airtime for
specific interests when needed. This would also allow for more efficient
use of spectrum.
There is no reason that we should not use any bands we can for
recreational, experimental and commercial use when there is not an
emergency situation. As long as the priority is in place to force the
airtime for public safety then we can hand it over instantly if needed.
If devices had to ask permission to transmit based on a base station
priority system then that system could be used for any purpose including
100% public safety in a disaster. Allowing the priority of traffic to be
established instantly means that any interest could make use of the
bandwidth under certain conditions as established by a base station with
priority control over traffic in real time. We already have some
spectrum exclusively used for specific interests. I think all the rest
should have multiple use ability.
I may not be doing a good job of describing what I am suggesting but the
whole point is that airtime priority partitioning is more important than
band exclusivity. We need to start designing and building communications
systems with this approach in mind.
