5 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 5 TGp Member Polls* Can devices (802.11) be made to communicate using B-links? YES: 5 NO: 0 Can devices (802.11) be made to communicate using P-links? YES: 5 NO: 0 Can devices (802.11) be made to communicate “simultaneously using ”** P-links and B-links? YES: 3 NO: 0 Not Sure: 2 * There were 9 people in the room when the polls were conducted. ** “Simultaneously using” means “sequentially queue” P-link and B-link frames for transmission.

Do you believe there is a technical reason why devices (802.11 STAs) can not communicate over B-links? YES: NO: Do you believe there is a technical reason why devices (802.11 STAs) can not communicate over P-links? YES: NO: Do you believe there is a technical reason why devices (802.11 STAs) can not communicate “simultaneously using”* B-links and P-links? YES: NO: * “Simultaneously using” means “sequentially queue” P-link and B-link frames for transmission.

10 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 10 A BIT OF HISTORY

11 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 11 (SLIDE 3: 11-04-0135-01-wave-summary- recommendations-wave-using-802-11.ppt) Beacon Suppression Beacons are not transmitted on the Control Channel –No network association; devices are not required to join a network prior to data transmission/reception (pseudo IBSS mode) …

12 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 12 (SLIDE 3: 11-04-0135-01-wave-summary- recommendations-wave-using-802-11.ppt) Service Channels can utilize Beacons according to information received on the Control Channel (Control Channel mode is also permitted) –Determined by upper layers (RSU service table) –Typical 802.11 networks can be established on Service Channels

13 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 13 (SLIDE 4: 11-04-0135-01-wave-summary- recommendations-wave-using-802-11.ppt) Authentication & Association Not permitted on the Control Channel –Security Keys are managed by upper layers Permitted on Service Channels according to information received on the Control Channel

14 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 14 (SLIDE 8: 11-04-0135-01-wave-summary- recommendations-wave-using-802-11.ppt) Priority Mechanisms Priority is needed to provide priority access to public safety applications, particularly on the Control Channel –No Beacons, assumes simply the use of AIFS (802.11e) rather than using DIFS –Full range of QoS mechanisms can be used on the Service Channels

15 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 15 (SLIDE 32: 11-04-0793-01-wave-wave-concepts- update-proposed-document-additions.ppt) Queue Routing Triggers Channelization function uses IPv6 destination address –Based on destination MAC if unicast –Based on IPv6 Prefix (and Subnet ID) if broadcast May need multicast address trigger May need multicast group address designation in PST –Second radio required if more than one service channel used per RSU Unique MAC per radio (can use “virtual radios” – multiple MAC per PHY) Unique IPv6 prefix

16 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 16 (SLIDE 32: 11-04-0793-01-wave-wave-concepts- update-proposed-document-additions.ppt) Channelization Overview Generalized Approach – One set of prioritized queues for each channel –A simple implementation may support only one service channel at a time (single set of prioritized queues)

17 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 17 (SLIDE 9: 11-04-0135-01-wave-summary- recommendations-wave-using-802-11.ppt) Summary Extra time associated with scanning and association has been removed by simplifying the MAC on the Control Channel, where all communication devices are initialized Service Channels can use “simple MAC” or extensive MAC features (e.g. 802.11e and i) 10 MHz channel parameters are consistent with 802.11j

18 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 18 (FROM SLIDE 3: 11-04-0135-01-wave-summary- recommendations-wave-using-802-11.ppt) Service Channels can utilize Beacons according to information received on the Control Channel (Control Channel mode is also permitted) –Determined by upper layers (RSU service table) –Typical 802.11 networks can be established on Service Channels

21 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 21 ANOTHER EXAMPLE Intel® My WiFi Technology – Intel announced the availability of Intel My WiFi technology, a wireless driver and software update to Intel® Centrino® 2 processor technology based laptops. This software enables a WiFi Personal Area Network (PAN) for WiFi Certified™ consumer electronic devices such as photo frames, cameras and printers. Intel doubles the laptop’s WiFi capability, with no additional hardware, by employing a virtual second WiFi interface. The dual interface takes advantage of available Intel® 5100 WiFi Link and Intel® 5300 WiFi Link adapters as well as existing antennas to manage both Wireless LAN and WiFi PAN connections.

22 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 22 CONCLUSION It is possible to implement “simultaneous” B-link (“inside”) and P-link (“outside the context of a BSS”) on currently available 802.11 devices.

23 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 23 SUBMISSIONS The following submissions provide text changes to the latest 11p draft that attempt allow this functionality to be developed and be 802.11 compliant: –11-08-1375-03-000p-clause 5 changes.doc –11-09-0102-05-000p-clause 7 MAC frame header related changes.doc

24 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 24 TGp Member Polls Do you believe TGp should allow for currently available 802.11 devices to “simultaneously” engage in B-link and P- link operations? YES: 1 NO: 1 People present: 9

25 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 25 TGp Member Polls IF YOU ANSWERED NO TO THE PREVIOUS QUESTION: Are you willing to provide a valid technical reason why you do NOT believe TGp should allow for currently available 802.11 STAs to “simultaneously” engage in B-link and P-link operations? YES: 1 NO: 0

26 doc: IEEE 802.11-09/0395r2 Submission March 2009 R. Roy, ConnexisSlide 26 TGp Member Polls Do you think it would be appropriate to form a Study Group to study the issue of whether the 802.11 standard should allow for currently available 802.11 devices to “simultaneously” engage in B-link and P- link operations? YES: 4 NO: 1 People present: 9
