1 doc.: IEEE 802.11-11/1163r0 Submission September 2011 Dave Halasz, Oaktree WirelessSlide 1 Status of IEEE 802.11ah and relevance to the Smart Grid Date: 2011-9-4 Authors:

2 doc.: IEEE 802.11-11/1163r0 Submission September 2011 Dave Halasz, Oaktree WirelessSlide 2 Abstract The following presentation gives a status of IEEE 802.11ah and it’s relevance to the Smart Grid.

3 doc.: IEEE 802.11-11/1163r0 Submission Activity leading up to IEEE 802.11 Sub 1 GHz Study Group November 2009, Smart Grid Tutorial describes using IEEE 802.11 in Neighborhood Area Network going to electric meter and inside the home. [1] January 2010, Presentation in IEEE 802.11 WNG describes creating an amendment in IEEE 802.11 for Sub 1 GHz operation. [2] March 2010, Feedback on the January presentation was given. [3] March 2010, IEEE 802.11 Study Group formation was approved. September 2011 Dave Halasz, Oaktree WirelessSlide 3

4 doc.: IEEE 802.11-11/1163r0 Submission Initial thoughts 2.4 GHz already present inside the home. Re-banding effort Use common IEEE 802.11 MAC Use sub 1 GHz for longer range Star architecture for meter access IEEE 802.11s mesh for backhaul September 2011 Dave Halasz, Oaktree WirelessSlide 4

5 doc.: IEEE 802.11-11/1163r0 Submission IEEE 802.11 Sub 1 GHz Study Group Activity Purpose of SG is to create a Project Authorization Request (PAR). Define scope of work to be done. PAR scope started as, –Re-banding effort of OFDM and add narrower channels Major comments heard and responded to was, –Treat as new OFDM PHY rather than just re-banding of OFDM Ended as [4], –Re-banding of 802.11 OFDM and other OFDM submissions are within scope Exclude TV (not just TVWS) bands Explicitly noted coexistence with.15 radios September 2011 Dave Halasz, Oaktree WirelessSlide 5

6 doc.: IEEE 802.11-11/1163r0 Submission Study Group to Task Group timeline September 2011 Dave Halasz, Oaktree WirelessSlide 6

7 doc.: IEEE 802.11-11/1163r0 Submission Interest in IEEE 802.11 Sub 1 GHz grows By 2 nd Task Group meeting, attendance was growing. It was clear that some process was needed. A specification development process document was approved in March of 2011 [5]. The process requires development of guiding documents. –Usage Model document –Channel Model document –Functional Requirements and evaluation methodology document –Specification Framework Ad hoc sub groups develop IEEE 802.11ah draft text from Specification framework document. September 2011 Dave Halasz, Oaktree WirelessSlide 7

13 doc.: IEEE 802.11-11/1163r0 Submission Forecast on Specification framework Instead of typical direction of speed improvements, go farther and more reliably. Decide on channelization –Channel bandwidth –Number of carriers –etc. Include repetition for improved reliability etc. September 2011 Dave Halasz, Oaktree WirelessSlide 13
