I joined the 802.19.1 teleconference call late, but I
heard the last of the presentation and I have reviewed the material. I
have not been privy to all of your discussions, but I do have some questions
after having reviewed the material. 1. From a practical perspective in the
architecture, what is the incentive to implement a system that is within
the 802.19.1 scope? 2. Who or what would implement the 802.19.1 scope
architecture? 3. Do whitespace participants have a requirement to
do any coexistence methodology outside of the Whitespace Database and some
scanning? It appeared to me that the primary incentive might be
handover and thought that it might fit within the 802.21 handover scenario and
use cases. I have reviewed some of the documents of 802.21 and the
closest that comes to even describing 802.21 requirements is the Zuniga
document on use cases and requirements that was a draft in 2009
(21-09-0041-03-bcst-broadcast-services-use-cases-and-requirements.doc).
It appears that 802.21 activity has been primarily focused on security and
physical handover. However, I did find an 802.21 document from May that
is at (https://mentor.ieee.org/802.21/dcn/10/21-10-0107-01-0000-thoughts-on-ieee-802-19-1-relation-with-ieee-802-21.ppt
) that exactly makes this point. It has not been presented in
802.19. I would suggest that you get the presenters of the 10/107r1
document [Antonio de la Oliva (UC3M), Johannes Lessmann (NEC), and Christian
Niephaus (FhG)] to present to the 802.19.1 group and seriously consider if
there is an audience and consumer of 802.19.1 services. Richard Paine Success is getting what you want, happiness is liking what you
