    Operating Classes and Channel numbers
 • 11n allows 40 MHz and 20 MHz operation in the same BSS at the same
   time
       – Country information does not show current 40 MHz and current 20 MHz
         channel numbers in Probe Response, so must be changed
       – Extended Channel Switch does not specify new channels for 40 MHz and 20
         MHz after the switch, so must be extended
 • Is possible to have three channel bandwidths in same band at same
   time (5-, 10-, 20-MHz), so operation with three bandwidths should be
   specified
 • 11-10/210 created Global Operating Class table
       – First index is frequency band, numbers below 81 are reserved
       – First subindex is channel bandwidth, largest to smallest
       – Values of 192+ are Vendor Specific, based on OUI

                 Global Operating Classes

 • Operating Class / Channel Number tuples in every
   command and report
       – See 11-10/210r8 Table I-2 and J-4
 • Context includes Country information, regulatory
   requirements, transmit power, exchange of OUIs and
   non-standard behaviors
 • Vendor Specific operating classes are used to carry information
   not defined in this standard within a single defined format, so that
   reserved operating classes are not usurped for nonstandard
   purposes and so that interoperability is more easily achieved in the
   presence of nonstandard information.

               Sub-GHz Operating Classes

 • One mandatory class per subband/channel bandwidth,
   knowing the regulatory domain of operation
       – 6 Mandatory/optional classes: 450-510 MHz, 779-787 MHz, 863-
         870 MHz, 896-960 MHz, 1427-1518 MHz, 2400-2497 MHz for
         200 kHz Generic PHY
       – Other Mandatory/optional classes for 802.11 PHYs?
       – Many TVWS classes are being defined in 802.11af
       – Everything else to be Vendor-Specific – operating classes 192-253

                  Operating Classes Issues

 • AP/BSS is considered to be operating under a list of
   current operating classes. This affects two things:
       – On doing an extended channel switch, you potentially change
         from one list of class/channel tuples to a different list.
       – A STA prior to association needs the intersection of the set of
         operating classes it supports and those in operation at the AP to be
         non-empty
 • Negotiating context information
       – Country information, regulatory requirements, transmit power,
         exchange of OUIs and non-standard behaviors, receiver
         configuration per class
       – TBD receiver configuration following Extended Channel Switch

•     Focus is on consistency across all WGs:
       – P802.11mb_D3.0
       – 11-10/210r8 Operating Classes
       – d1P802.15-4g_Draft_Standard
