Hi Rich,
Attached is 11-09/469r0 with your changes, for posting to 802.18 at your
convenience.
I will email and post a changed doc if Brian Hart, Eldad Perahia or Vinko
Erceg asks to be a co-author or asks for changes.
If nothing changes by early Monday, could you post to both 802.18 and
802.11?
Thanks in advance,
petere

Hi Rich,
You are right, the document should be an 802.11 WG document.
Who should I send it to asking for coauthors?

Why WNG? Does the SC have equal status with the .22WG in 802.18?

Hi Rich,
I just spoke with Mike Lynch, and will do a WNG submission with text for
John Notor to blend in with whatever 802.22 submits
e.g.
Question 8. Do you agree with a sensitivity requirement for -126 dB (in a
200 kHz
channel) for wireless microphones?
In our view, there are only two practical means to protect wireless
microphone operation while allowing reasonably effective operation of
license-exempt devices in the interleaved spectrum, one is the use of
geolocation for the license-exempt devices associated with access to a
database where all wireless microphone operation would be documented prior
to their operation so that the push-technology proposed for dissemination of
timely information from the database can create the required local
protection 'bubble' before wireless microphone operation starts, the second
one is the use of a local RF beacon such as the IEEE 802.22.1 beacon by the
wireless microphone operator.
Q14
Question 14. How could the database approach accommodate ENG and other
similar applications?
ENG is an activity generally involving a number of people in a broadcast
organization. From the break out of the news usually signalled by a
telephone call to the managed decision of actually dispatching a news
gathering crew, to the time the news is recorded or broadcast live from the
site of the event, one can foresee that, at least, a few minutes be needed
between the initial break out and the actual broadcast. This would give time
to management to update the database through Web access with a request for
some frequencies for wireless microphones for ENG purposes in the given
area. Well-known push technology used on the Internet is expected to be
used to update the nearby license-exempt devices to clear the channels if
they are connected to the Internet.
The database approach would allow for this, whereby an authorised person
defines the frequency range to be provided protection, the geographical area
over which the protection is to be offered and the time period at which it
applies. Moreover, it is quite conceivable that the news crew itself could
make such a request over the internet or have a device that could make such
a request, providing a near instantaneous temporary "bubble" of protection
around them, including the possibility of a "mobile" bubble if the ENG event
is mobile.
In general (from 802.11-09/0239r2)
Q8 The sensing threshold for wireless microphones should be -126 dB (in a
200 kHz channel)
Q 25. Do you agree that a maximum time between checks for channel
availability should be 1s?
Synchronized quiet periods are necessary for incumbent sensing
Regarding these points, it is impossible to sense whether a wireless
microphone is being operated by a licenseholder or if it is being operated
without a license. The vast majority of mics in use today do not enjoy
protection. The only technically feasible way for OFCOM to address this
issue is to have licensees enter geolocation information in the database and
then require that white space devices receive relevant database updates more
frequently.

Peter:
I can't figure this one out. I got your message in this email. I have
things to learn about the RIM system.
I agree with the plan to just take exceptions to the same things we did in
the FCC TVWS .18 debate.
