Hi,
Ok you may see different scenarios under the LSA concept but so far it
has been thought as an enabler to contribute to more frequency bands for
mobile broadband with "individual" licenses of "10 to 15 years" duration
where such "a protocol for a device to ask for spectrum to use" may not
be the obvious implementation.
Note i do not disagree that PAWS is not limited to TV bands.

Absolutely!
PAWS is a protocol for a device to ask for spectrum to use. As such
the PAWS protocol must include enough information for the database to
decide what answer to give.
The response must clearly define what access rights the device has
been given.
No more, no less.

I would respectfully disagree with the conclusion below. The interface
between the Radio (device) and the Database is for accessing available
(white space) spectrum. The policy on how to determine if the spectrum
is available (or not) is separate from the Interface. If the Regulator
chooses to implement a specific policy regarding sharing such as
including prioritization of users, limiting the number of concurrent
users or allowing unlicensed access of a band it is internal to the
database implementation for that location/Regulator. IMHO the value of
the interface is to provide an abstraction for devices worldwide
regarding the potential numerous regulatory policies.
My understanding since the beginning was we were not limiting the
scope to TVWS; hence the title PAWS and not PATVWS.

Hi Brian, Hassnaa,
Despite having some characteristics in common, LSA and WS are, to me,
different animals and i doubt there is enough synergy between WS & LSA
to fall naturally into the scope of PAWS: "Sharing under the LSA is
binary by nature, with spectrum being used by either the incumbent(s)
or the LSA licensee(s). I believe PAWS framework (i.e. direct link
between a DB and a master device) is tightly coupled with the
unlicensed nature of WS concept where LSA is about "exclusive spectrum
rights of use where and when the spectrum is not used by the
incumbent(s)".

Our goal in the IETF is to be as widely applicable as we can
within our charter, balanced against getting something done sooner
rather than later.
That's probably not as helpful as you would like.
I think LSA is in scope = we're definitely not limited to TV
bands, and we're not limited to unlicensed spectrum.

Hi Brian, Gabor and all,
I read the last use-cases draft
(draft-ietf-paws-problem-stmt-usecases-rqmts-12.txt) and the
recent version of the protocol draft, and I notice that the
use-cases focus on White Spaces utilization.
I have a couple of questions:
- Does the WS database aims to consider the TVWS only or any other
frequencies (WiFi, cellular, ... for instance)?
- In the charter of the WG, the scope is on WS utilization, would
the PAWS protocol under progress be applicable to (LSA: Licensed
Share Access) also or would be limited to the WS?
Thanks in advance.
Regards,
Hasnaa
