PAGE 2 General Background: PAP2 in SGIP Smart Grid Interoperability Panel Priority Action Plan 2 ( ) works on wireless technologies for smart gridSmart Grid Interoperability PanelPriority Action Plan 2http://collaborate.nist.gov/twiki-sggrid/bin/view/SmartGrid/SGIP In January 2011, PAP2 approved a document summarizing its work in 2010, “Guidelines for Assessing Wireless Standards for Smart Grid Applications.” ( sggrid/pub/SmartGrid/PAP02Objective3/NIST_PAP2_Guidelines_for_Assessin g_Wireless_Standards_for_Smart_Grid_Applications_1.0.pdf)Guidelines for Assessing Wireless Standards for Smart Grid Applicationshttp://collaborate.nist.gov/twiki- sggrid/pub/SmartGrid/PAP02Objective3/NIST_PAP2_Guidelines_for_Assessin g_Wireless_Standards_for_Smart_Grid_Applications_1.0.pdf –Guidelines’ main content is a discussion of wireless air interface modeling –Specific technology performance in that document is from the respective SDOs in the Annex A through E: Wi-Fi, LTE, HSPA, cdma2000, and WiMAX In 2011, PAP has been focusing on the evaluation of wireless technologies –In the SGIP Catalog of Standards ( sggrid/bin/view/SmartGrid/SGIPCatalogOfStandards), none of the cellular standards have been “identified.” cdma2000 1x and HRPD are listed under the “under review” section.Catalog of Standardshttp://collaborate.nist.gov/twiki- sggrid/bin/view/SmartGrid/SGIPCatalogOfStandards 2 C NN

PAGE 3 Wireless Technology Evaluation in PAP2: Wireless SDOs The PAP2 SDO subcommittee, consisting of representatives from IEEE , ATIS, TIA TR45.5, and WiMAX Forum, continues to develop technology assessment methodology –The group meets every Tuesday 9:00 AM to 10:30 AM Eastern Time –The goal is to refine the NIST IR 7761 Guidelines for Assessing Wireless Standards for Smart Grid Applications, with a focus on the wireless communication aspects –SDO subcommittee reports progress to PAP2 during biweekly PAP2 calls Recent focus of the PAP2 SDO subcommittee is to complete chapters 4, 5, and 6 of the guideline document –Chapter 4: Wireless technology descriptions correspond to “Wireless Functionality and Characteristic Matrix for the Identification of Smart Grid Domain Applications” ( sggrid/pub/SmartGrid/PAP02Objective2/Consolidated_NIST_Wireless_Characteristi cs_Matrix-V5.xls)“Wireless Functionality and Characteristic Matrix for the Identification of Smart Grid Domain Applications” ( sggrid/pub/SmartGrid/PAP02Objective2/Consolidated_NIST_Wireless_Characteristi cs_Matrix-V5.xls –Chapter 5: wireless technology evaluation method that includes an initial screening and refinements to the screening using a combination of analysis, simulation, and/or testbed in the field. –Chapter 6: Performance metric and associated considerations 3 C NN
