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.

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)". Regards, Pierre-Jean Muller RED Technologies Le 07/02/2013 19:35, Rosen, Brian a écrit : 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. brian From: Hassnaa Moustafa <[email protected]<mailto:[email protected]>> Date: Thursday, February 7, 2013 1:32 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [paws] Spectrum Sharing 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 _______________________________________________ paws mailing list [email protected]<mailto:[email protected]> https://www.ietf.org/mailman/listinfo/paws
