New Broadband Plan • Recommendations • Integrate broadband into the Smart Grid • ➤ As outlined in Chapter 16, the Federal Communications Commission (FCC) should start a proceeding to explore the reliability and resiliency of commercial broadband communications networks. • ➤ States should reduce impediments and financial disincentives to using commercial service providers for Smart Grid communications. • ➤The North American Electric Reliability Corporation (NERC) should clarify its Critical Infrastructure Protection (CIP) security requirements. • ➤Congress should consider amending the Communications Act to enable utilities to use the proposed public safety 700 MHz wireless broadband network. • ➤The National Telecommunications and Information Administration (NTIA) and the FCC should continue their joint efforts to identify new uses for federal spectrum and should consider the requirements of the Smart Grid. • ➤The U.S. Department of Energy (DOE), in collaboration with the FCC, should study the communications requirements of electric utilities to inform federal Smart Grid policy. http://download.broadband.gov/plan/national-broadband-plan.pdf Bruce Kraemer, Marvell
Broadband Plan Recommendation 12.4 • Recommendation 12.4: • Congress should consider amending the Communications Act to enable utilities to use the proposed public safety 700MHz wireless broadband network. • The wide-area network requirements of utilities are very similar to those of public safety agencies. Both require near universal coverage and a resilient and redundant network, especially during emergencies. In a natural disaster or terrorist attack, clearing downed power lines, fixing natural gas leaks and getting power back to hospitals, transportation hubs, water treatment plants and homes are fundamental to protecting lives and property. Once deployed, a smarter grid and broadband-connected utility crews will greatly enhance the effectiveness of these activities. • Congress should consider amending the Communications Act to enable utilities to use the public safety wireless broadband network in the 700MHz band, subordinated to the communications of Section 337-defined public safety services. Jurisdictions that are licensees or lessees of the public safety 700MHz broadband spectrum should be allowed to enter into agreements with utilities on uses and priorities. At the sole discretion of the public safety licensee, utilities should also be able to purchase services on a public safety network, contribute capital funds and infrastructure or even be the operator of a joint network. These statutory changes should create more options for the construction and operation of a public safety wireless broadband network. Although the network will take years to build, carrying critical traffic from multiple users can help lower costs for all. http://download.broadband.gov/plan/national-broadband-plan.pdf Bruce Kraemer, Marvell
Broadband Plan Recommendation 12.6 • Recommendation 12.6: The U.S. Department of Energy (DOE ), in collaboration with the FCC , should study the communications requirements of electric utilities to inform Federal Smart Grid policy. • Understanding the evolving communications requirements of electric utilities will help DOE develop informed Smart Grid policies for the nation. As an input to this plan, the FCC solicited public comment on Smart Grid technologies, and a number of utilities filed detailed responses. However, many utilities declined to comment, and others understandably declined to reveal confidential or sensitive information in public filings. • DOE, in collaboration with the FCC, should conduct a thorough study of the communications requirements of electric utilities, including, but not limited to, the requirements of the Smart Grid. Building upon the FCC’s recent efforts, DOE should collect data about utilities’ current and projected communications requirements, as well as the types of networks and communications services they use. http://download.broadband.gov/plan/national-broadband-plan.pdf Bruce Kraemer, Marvell

Tough Questions • What are the consequences of not responding to the request? • How much effort, from whom, how quickly needs to be contributed to meet the request? • Could the June deadline for task completion be extended? • How will the data provided to NIST be used by other entities in influencing deployment decisions? • “Entities” range from FERC to consumer appliances • Can simulation models be useful enough without selecting and constructing channel models? Bruce Kraemer, Marvell
Working Assumptions • The ongoing interchange of information between power engineering and communications industry is essential. • Computer modeling communications against PE supplied uses cases is far more useful than hand waving. • Although not fully understood or quantified, there will be business incentives to being recognized as a qualified Smart Grid technology. • Although not fully understood, industry would prefer to be “actively influencing” the technology selection process rather than have it dictated to them. Bruce Kraemer, Marvell

Initial Questions from Ted Booth • As part of the PHY model, it’s not clear how NIST derived interference (I0 ) first introduced on slide 16. In 802.11 access methods, usually, interference means signals from other BSS or other device's signal emission on the operating channel. However, it’s not clear what NIST assumes here. Comments? • Regarding Transmit Power Control (TPC) (slide 17), Sony believes most of the current 802.11 devices do not apply dynamic transmit power control. What’s your assessment here? The NIST Models allow for either approach. Comments? • Looking again at TPC in the MAC Model, traditionally most 802.11 implementations try to use the best MCS to achieve higher throughput; this will significantly impact results out of the Model. How should the Model properly takes this into account? Bruce Kraemer, Marvell
