21. Study Findings

22. Overall Findings Most users are urban
Most robust solutions should focus there
All have needs for high bandwidth (>1MB)
Metro Wi-Fi is the clear solution but is too complex and costly to deploy and operate
Mission critical users require multiple network alternatives
Private sector hedge
Many assets available that are valuable to 3rd party wireless providers
Countless numbers of unique applications
AMR, ITS, GIS, GPS, asset tracking, remote surveillance……..endless
Cooperative County Environment

23. Next Steps Submit RFP for Consultant Services
Approve Cooperative Agreement between Cities and County
Research Legal Issues
Perform Study
Develop Requirements
Technology Infrastructure Assessment
Business Model Review
Public/Private Process
Utility
Cost/Financing
