1. Survivability Considerations for Design of Government Private Wireless Networks Clay Whitehead Motorola Networks and Enterprise

2. 2 Private Land Mobile Radio Terrestrial based wireless communications Offers customized coverage, capacity, control and feature sets Primarily hand-held communications devices One to many dispatch call model – voice is priority Disparate frequency bands – government agencies hold the licenses Private government funded network Mostly proprietary technology, but rapidly moving towards standards-based platforms What is Land Mobile Radio?

3. 3 Private Land Mobile Radio Extended power grid failures Failure of back-up power systems Network connectivity lost Extensive flooding of facilities and equipment shelters Towers fail Point to point links fail Single points of failure in critical components/subsystems E911/Dispatch center evacuations Lightning damage to equipment When do LMR Systems Fail?

4. 4 Private Land Mobile Radio Many remain fully or partially operational – Full coverage and capacity – Fallback modes of operation – Reduced coverage or capacity Those impaired or with minor failures are usually restored shortly thereafter What Happens to First Responder Communication Systems?

5. 5 Private Land Mobile Radio Robust coverage and RF saturation/innovative in-building penetration solutions Stricter site design standards Redundancy of all critical control components Allocate additional capacity and spectrum for State and Local Government (broadband) Enhance network security and monitoring tools Soft-switch interfaces between public and private systems Fuel cell technology for handheld/mobile devices Enhanced disaster recovery solutions Where Can We Improve Survivability?

7. 7 Private Land Mobile Radio Denser site configuration; more RF saturation More overlap between sites, including simulcast cells in the urban areas Individual site failures have less impact LMR Radio System Coverage – Illinois Starcom 21 Network

8. 8 Private Land Mobile Radio Composed of manufacturers, commercial real estate companies, cellular carriers and first responders Value to public safety – Ability to communicate within buildings and from inside the building to command and control locations – Improved situational awareness, command and control – Fewer injuries and loss of property and life – Decreased response time for fire or injury emergency – Critical communications for instruction and evacuation IBWA - In Building Wireless Alliance

9. 9 Private Land Mobile Radio Design for Category 5 hurricanes in coastal areas/hurricane landfall zones – Towers with higher wind load ratings – Hardened physical security Elevated sites and power systems Main Switching Office redundancy Back up site connectivity – Telco – Point to point microwave – Spread spectrum technologies – Satellite Enhance LMR Communication Site Standards
