Submission doc.: IEEE /0564r0 Slide 4 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 Peter Ecclesine (Cisco Systems)

Submission doc.: IEEE /0564r0 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.

Submission doc.: IEEE /0564r0 Sub-GHz Operating Classes One mandatory class per subband/channel bandwidth, knowing the regulatory domain of operation –6 Mandatory/optional classes: MHz, MHz, MHz, MHz, MHz, MHz for 200 kHz Generic PHY –Other Mandatory/optional classes for PHYs? –Many TVWS classes are being defined in af –Everything else to be Vendor-Specific – operating classes May 2010 Peter Ecclesine (Cisco Systems)Slide 6

Submission doc.: IEEE /0564r0 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 May 2010 Peter Ecclesine (Cisco Systems)Slide 7
