Subject: identical comment on 802.19 PAR, 802.22PAR and 802.11PARs on TV White Space

Steve, Bruce, Wendong,

Please circulate the following comments to your respective WGs regarding the 
draft PARs on TV Whitespace.

1) The proposed 802.11 TV Whitespace PAR contains coexistence language
"It is in the best interest of users and the industry to strive for a level 
of coexistence between wireless systems in the TVWS bands.  WG11 TVWS 
provides mechanisms for coexistence with other systems.  One approach is a 
common coexistence mechanism that may be used by other TVWS systems; other 
approaches are also possible."

2) The proposed 802.22 modified PAR also contains coexistence language
"It is in the best interest of users and the industry to strive for a level 
of coexistence between wireless systems. The IEEE 802.22 WG provides 
mechanisms for coexistence with other systems in the TVWS band. One approach 
is a common coexistence mechanism that may be used by other TVWS systems; 
other approaches are also possible.

3) The proposed 802.19 TV Whitespace Coexistence Mechanisms PAR contains 
coexistence language
Scope: "The standard specifies mechanisms for coexistence among dissimilar 
or independently operated TV Band Device (TVBD) networks and dissimilar TV 
Band Devices." and
Purpose: "The purpose of the standard is to enable the family of IEEE 802 
Wireless Standards to most effectively use TV White Space by providing 
standard coexistence mechanisms among dissimilar or independently operated 
TVBD networks and dissimilar TVBDs. This standard addresses coexistence for 
IEEE 802 networks and devices and will also be useful for non IEEE 802 
networks and TVBDs."


My comment:
There is a fair degree of common language in the coexistence language taken 
from the above 3 draft PARs addressing the TV Whitespace bands.

Since the 3 draft PARs  (dot 19, dot11 and dot22) are being proposed 
simultaneously the groups haven't had much time to work on coordinating 
their activities on the draft PAR language.  However it will be useful for 
EC members to better understand how the groups are thinking about 
coordinating their coexistence specifications going forward.

I understand the groups have begun general discussion on coordinating their 
activities--this is good.  I believe any specifics that each of you can 
provide regarding future coordination mechanisms among the 3 projects would 
be useful to the EC members.

Regards,

--Paul
