Hi Ron and others,
Based on Ron's request during discussion today in the REG SC meeting
in AM2 slot,
here are suggested rewordings for the comments I made in the
meeting:
1.Change Page 2 text FROM:
"
802.11
RECOMMENDS THE COMMISSION ALLOCATE
A MINIMUM OF THREE 6MHz CHANNELS
ON A NATIONAL BASIS WITH POWER LIMITS ON-PAR WITH CURRENT FCC
TVWS REGULATION
20 years of engineering analysis and deployment experience with
802.11 in the 2.4 GHz band
confirms that a minimum of three channels is required for
successful WLAN deployments. "
TO:
"802.11
RECOMMENDS THE COMMISSION RESERVE
FOR TVWS A MINIMUM OF 18MHz OF USEABLE SPECTRUM
IN ALL LOCATIONS, WITH POWER LIMITS ON-PAR WITH CURRENT FCC
TVWS REGULATION
20 years of engineering analysis and deployment experience with
802.11 in the 2.4 GHz band
indicates that a minimum of three channels is adequate for
successful WLAN deployments. The
18 MHz of TVWS in this recommendation is equivalent to three TV
channels but may include discontinuous
spectrum pieces with minimum useable BW of 1.5MHz. Per current
regulations, the frequencies
of this reserved 18MHz TVWS spectrum may vary from city to city
and is dynamically controlled by regulatory
geolocation database to protect primary users. Furthermore,
802.11 recommends that any auctioned
TV spectrum which is unused by the new licensee be treated as TVWS
spectrum, with the regulatory geolocation
database providing protection for the licensed primary users."
NOTE: Since we are drafting this recommendation to represent all
of 802.11, I suggest that
we acknowledge that low-power, low-bandwidth, and low-duty cycle
Smart Grid devices will be using
TVWS. This includes using channel bandwidths less than 6MHz.
802.11ah is defining WLAN 1.5MHz
channels and therefore I suggest we accommodate this as a minimum
channel bandwidth in our recommendation.
Comments and discussion may continue on this reflector and in the
upcoming 802.11 REG SC meetings and
teleconferences.
Best regards,
