2. doc.: IEEE 802.11-10/0174r0 Submission January 2010 Bruce Kraemer, MarvellSlide 2 High Level Questions What is happening in Smart Grid arena? Is 802.11 properly positioning its existing and pending standards and amendments for acceptance in SG? Participation in key Smart Grid activities Are there any identifiable additions or changes that should be considered to make 802.11 more useful in SG domains?

5. doc.: IEEE 802.11-10/0174r0 Submission January 2010 Bruce Kraemer, MarvellSlide 5 Operating Point Group Discussion Harmonize operating point based upon: Operating environment 1.Inside a house –Primary: Range, data rate, latency, noise environment –Secondary (QoS): Reliability, availability (need to include additional layers) (bit, packet) 2. Sub-station & generating plant –Range, data rate, latency, noise environment 3. Collection – back haul - long range –Range, data rate, latency, noise environment

6. doc.: IEEE 802.11-10/0174r0 Submission January 2010 Bruce Kraemer, MarvellSlide 6 Operating Point Group Discussion Regarding request that operating point include Availability and Reliability, how to measure these parameters? Group conclusion: reuse terms from matrix E.g., Link availability is measured as failure rate per 1000 sessions

7. doc.: IEEE 802.11-10/0174r0 Submission January 2010 Bruce Kraemer, MarvellSlide 7 Consideration of NIST Link budget Method http://www.antd.nist.gov/wctg/manet/prd_linkbudgetcalc.htmlhttp://www.antd.nist.gov/wctg/manet/prd_linkbudgetcalc.html GENERAL PURPOSE LINK BUDGET CALCULATOR For arbitrary wireless communication radio links, this calculator explains the terms in the link budget and gives the user the opportunity to enter or change the parameters. Macros invoked by clicking on buttons guide the user through the various options for selecting and entering the parameters. For definiteness, the calculator uses the Hata outdoor propagation loss model. The calculator was developed as an Excel spreadsheet application by Leonard Miller. It uses a new method for calculating the link margin needed to achieve a desired reliability when there is both lognormal shadowing and Rayleigh fading.new method SOFTWARE DOWNLOAD FILE Excel spreadsheet: download request form Version 1.24, added reminder to recalculate noise power when rate is changed 1/17/06 (Complete revision history listed on page 1 of spreadsheet)download request form

8. doc.: IEEE 802.11-10/0174r0 Submission January 2010 Bruce Kraemer, MarvellSlide 8 Establish Smart Grid ad hoc Provide a forum for on-going /timely review of Smart Grid topics –Encourage participation from other 802 groups Initial Topics: 1. Assist in the development & completion of PAP#2 2. Refine the 900 MHz project proposal 3. Begin Coordination with 15.4g Indentify other projects that would serve Smart Grid requirements Call organizer volunteer (temporary): Bruce Kraemer Conference calls: Wednesdays at 2pm Eastern starting on Feb 10 (no call on Feb 24)
