General Background: PAP2 in SGIP

• Smart Grid Interoperability Panel Priority Action Plan 2 (http://collaborate.nist.gov/twiki-sggrid/bin/view/SmartGrid/SGIP ) works on wireless technologies for smart grid

• In January 2011, PAP2 approved a document summarizing its work in 2010, “Guidelines for Assessing Wireless Standards for Smart Grid Applications.” (http://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP02Objective3/NIST_PAP2_Guidelines_for_Assessing_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 (

http://collaborate.nist.gov/twiki-sggrid/bin/view/SmartGrid/SGIPCatalogOfStandards), none of the cellular standards have been “identified.” cdma2000 1x and HRPD are listed under the “under review” section.

Wireless Technology Evaluation in PAP2: Wireless SDOs• The PAP2 SDO subcommittee, consisting of representatives from IEEE

802.11, ATIS, TIA TR45.5, and WiMAX Forum, continues to develop technology assessment methodology

– The group meets every Monday 9:00 to 10:30 a.m. PST – The goal of this group is to update 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” (http://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP02Objective2/Consolidated_NIST_Wireless_Characteristics_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 considerations3

Status of Guideline Development

• Chapter 4– 90+% complete– Pending final review of the text by the group– No plan for resubmitting the matrix

• Chapter 5 – Capacity estimation method and Link/MAC/System modeling review

complete– Spectrum choices and deployment modeling tool currently under review – Target to be completed by May 2012

• Chapter 6 – Has not started – Need to decide specific content and seeking lead editor– Additional details on the spectrum allocation and options in the US needs

to be considered

Modeling Tool Status

• Not yet fully reviewed by SDO-subcommittee

• Limited to land-based, outdoor BS, & PMP topology, indoor or outdoor terminal locations– 5 Outdoor path loss models to choose from– Covers 700 MHz to 6000 MHz– BS antenna heights 7 to 80 meters in rural and suburban with varied (but

not extreme) terrain characteristics – 10 meter BS antenna height for urban microcell, otherwise above rooftops– Handles TDD and FDD– Channel capacity estimates based on uniform distribution of terminals –

and will differentiate between DL and UL

• Estimates for penetration loss & interference margins based on limited data/references
