  2. Topics • What is Broadband Wireless (Wi-Fi)? • What is “Wi-Fi Mesh”? • Who is doing Wi-Fi? • Johnson County Activities to Date • Preliminary Study Findings • Next Steps

  3. What is Broadband Wireless? • Bringing Wireless Communications – Outside • Public Safety • Police • Fire • Building Inspection • Restaurant Inspection • Public Works Inspection • Parks Inspection

  4. Up to Now • Voice/radio • Reliable Deployments • No data (or minimal) • Has suited needs well and will continue to in some form

  5. Wireless Business Needs • AVL • Meter reading • Parking enforcement • Dispatch • GIS / Mapping • Property appraiser • Code enforcement • Video surveillance • 1st responders • VoWiFi • Mug shots • Broadband • Events • Amber Alerts • E-justice • Sensors • Freight REALITY • Not enough bandwidth • ‘Mobile Office’ is elusive Robust Wireless Apps MISSING LINK

  8. Wi-Fi Proliferation Wi-Fi Client Shipments 100 2004: 1,000+ devicesWiFi certified 90 80 2003: Wireless integrated ontoPC motherboard; Wireless device proliferation: laptops, PDAs, video cameras, etc. 70 60 50 2002: Wireless NIC: <$60 40 Wi-Fi Client Devices (millions) 2001: HP, Dell, IBM,Toshiba offer built-in wirelessWireless NIC: $100 30 20 1999: IEEE 802.11b (“Wi-Fi”) standard adopted;Wireless NIC: $200 10 0 1999 2000 2001 2002 2003* 2004* 2005* • 150M Wi-Fi devices: 2005 • 12.5M shipped per month • Has become the “Ethernet” wireless • Intel marketing giant • Mass integration

  9. Wi-Fi Mesh

  10. What is Mesh? • Radio “talks” to another directly over the air forming adjacencies

  11. Pole Mount Wi-Fi Radio Close-Up of Pole Mounting

  12. Meshing Cells

  13. Wireless County Concept

  14. Wi-Fi in Action - No Boundaries Entering Overland Park Entering Lenexa

  15. City of Philadelphia • 135 square miles • Primary mission was to bridge the Digital Divide • Widely publicized • City Open Access Model was original plan • Completely outsourced to 3rd party based on RFP

  16. Oklahoma City • 600 square miles • Police, Fire, EMS • Homeland Security • Part of general security overhaul (CAD, CRM, etc) • Fixed and mobile nodes • Broadband application access, voice and video • Funding • Tax • Grants

  17. Mountain View, CA • 12 sq mi • Completely outsourced • NO RFP • FREE Wi-Fi Internet • 300kbps • VLAN for city use • Experiment for Google • hometown

  18. Starting to be built… • These collaborative networks are being built • Philadelphia, PA • Tempe, AZ • San Francisco, CA • Mountain View, CA • Oklahoma City, OK • Chaska, MN • Moorehead, MN • St. Cloud, FL • Miami Beach, FL • Milwaukee, WI • New York, NY • Minneapolis, MN • Denver, CO • Houston, TX • Nashville, TN • St. Charles County, MO • Akron, OH • Sacramento, CA • etc…etc…etc…

  19. Activities To Date • Summer 2005 • Wi-Fi Partnering Opportunity Identified • Fall 2005 • Exploratory Meeting • Established Steering Committee • Winter 2005 • Conducted preliminary Review • Presented Findings to • City Managers • Council of Mayors • Cities

  20. Steering Committee • Bob Boyd Manager, Johnson County ITS Technical Services • Jack Clegg Director, Johnson County ITS • Vicki Irey Director, Overland Park ITS • Chris Kelly Director, Olathe ITS • Tim Mulcahy Director, Johnson County JIMS • John VanNice Director, Lenexa ITS • Walt Way Director, Johnson County Emergency Communications • Hannes Zacharais Deputy County Manager, Johnson County

  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
