The Spectrum Issue  As SDGE tried to spec & design a high-performance smart grid communication service, spectrum quickly became the key issue. We looked exhaustively at many options.  700 Mhz, 1.4 Ghz, 2.3 Ghz, 3.65 Ghz, 400 Mhz, 800/900 Mhz, 1.8 Ghz, TV white spaces…  2.3 Ghz WCS spectrum was the only option that survived our major filters :  Availability in our service territory  Affordability  Clear title  Equipment availability  Operational fit 3

WCS Spectrum *Amateur Radio Service has 5 MHz and is directly adjacent to A Block. The Federal Deep Space Receivers live between MHz **Aeronautical Mobile Telemetry Service operates at the upper adjacent edge between MHz

Service Design Goals Examples: Smart Grid devices

Policy Issues Going Forward  WCS  Continued good partnership with FCC on evolving the operations requirements in WCS bands  Testing & cooperation with WCS neighbors  Other critical infrastructure spectrum  Details on acquisition & usage of 700 Mhz public safety bands  Federal oversight of those bands  State & user governance of resulting shared networks  Cybersecurity requirements on communication infrastructure  Creating a value metric not based on “per consumer” 8
