Dear Scott and Raj and all,
I offer the following as edits to the document :
1.1 page 4
" Television transmission until now has primarily been analog. The
switch to digital transmission has begun. As a result the spectrum
allocated for television transmission can now be more effectively
used. Unused channels and bands between channels can be used as long
as they do not interfere with the primary service for which that
channel is allocated. While urban areas tend to have dense usage of
spectrum and a number of TV channels, the same is not true in rural
and semi-urban areas."
I would change
" While urban areas tend to have dense usage of
spectrum and a number of TV channels, the same is not true in rural
and semi-urban areas."
to
…..while urban areas tend to have dense usage of
spectrum and a number of TV channels, the same is not true in semi-rural,
rural and remote areas.
Since there are many countries that also have "remote" areas, I would consider
adding remote as a more global outlook for billions of people that live in
remote areas.
1.1 page 5
>> "In any country, the rules for which
>> primary entities are entitled to protection, how the exclusion zones

> To me I would change "are calculated, and what the limits of use by secondary

> are calculated, and what the limits of use are by secondary entities may

> ALso, I think you need a period after "are common" to end the sentence.
2.2. Terminology page 6
Database
In the context of white space and cognitive radio technologies,
the database is an entity which contains current information about
available spectrum at any given location and other types of
information.
I propose:
..."is an entity which contains, but is not limited to, current information
about available spectrum at any given location."
May avoid comments like…."what other types of information?"…and listing more
when you should not have to at this time???
>> 3.3. Air Interfaces page 8
>>

I propose:
Efforts are ongoing to specify air-interfaces for use in white space
spectrum. IEEE802.11af and IEEE802.15.4m task groups are currently working
on such efforts, and IEEE 802.22 , continues its work on the first WS standard
approved.
Other air interfaces could be specified in the future with LTE for example.
It makes it accurate and agnostic technology wise.
SIncerely, Nancy
