Difference of Potential
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.

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

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
Advantages Challenges700 MHz Spectrum Access to Utilities
Network Sharing with Public Safety (Prioritization)
Network Operations Cost Reduced Network Standards Timeframe
Potentially Good Backhaul Concentrator Network Use Charge to Utilities
Potentially Good for Workforce Mobility Applications

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

Current Option: Licensed Frequency 4.9 GHzConsiderations:
• 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
