1. Donivon Hettich Director Applications Engineering MSGS San Diego, CA June 5, 2012 Licensed & Unlicensed Spectrum Options Understanding Your Options

2. Who is S&C? Established 1911 in Chicago, IL 2500 employee owners in 5 global facilities Specialists in power protection & automation Leading innovator of hardware and technology

3. S&C’s Communication Systems Your consultative integrator of communications solutions specific to electric utilities.

4. Evolution of Information Processing • Localizedfundamental processing • Centralized processing with remote access • Distributed Intelligence articulating with central • Ubiquitous many to many communications

5. Difference of Potential What would Marconi think? Alexander Graham Bell The story goes like this: If Alexander Graham Bell were somehow transported to the 21st century, he would not begin to recognize the components of modern telephony – cell phones, texting, cell towers, PDAs, etc. – while Thomas Edison, one of the grid’s key early architects, would be totally familiar with the grid.

6. Ubiquitous Connectivity

7. Network of Networks Use Cases NOC LAN Backbone RTUs IEDs Large Substation WAN • What spectrum should be utilized? • No single communication system does it all • Differing use cases AMI-WAN DA-WAN NAN RTUs IEDs Field Area

8. Option: Public Versus Private Networks • UTC response to DOE request for information • Decision could be a hybrid • Network of Networks • Public normally licensed • Private licensed or unlicensed

9. Unlicensed or Licensed? • Unlicensed spectrum: • Ideal for: AMI, AMR, SCADA, Distribution Automation • 902-928 MHz, 2.4 GHz, 5 GHz • Easily and quickly deployed • Spectrum is free • Licensed spectrum: • Provide extended level of reliability (less interference) • Spectrum ownership cost

10. Licensed Frequency Trends

11. Licensed PSBN: Future Option • 700MHz Public Safety Broadband Network (PSBN) • Middle Class Tax Relief and Job Creation Act 2012 • Nationwide 4G LTE network that allows Utilities as secondary users to First Responders

12. Current Option: Licensed Frequency 4.9 GHz • In 2003, the FCC opened 50 MHz of the 4.9 GHz Public Safety Band to all U.S. state and local government entities, including municipal power companies • Point-to-multipoint are primary users(general license) • Permanent point-to-point are secondary users (separate site license), which must be used within 18 months of grant

13. Current Option: Licensed Frequency 4.9 GHz Considerations: • Apply at wireless.fcc.gov/uls, no charge, swift processing • Can’t interfere with radio astronomy observatories • 18 channels ranging from 1 MHz to aggregated 20 MHz

14. Unlicensed Frequency Trends

15. Frequency Diversity 4.9 GHz 5.8 GHz 2.4 GHz 5.4 GHz

16. Interference Mitigation 4.9 GHz 5.8 GHz 5.2 or 5.3 GHz 2.4 GHz 5.4 GHz

17. Aspects of Key Importance Flexible frequencies Post deployment

18. Getting Started… • Future Needs Assessment • Legacy Networks Assessment • Gap Analysis • Roadmap Planning • Project Implementation • Deploy, support and maintain
