Survivability Considerations for Design of Government Private Wireless Networks Clay Whitehead Motorola Networks and Enterprise
Private Land Mobile Radio What is 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
Private Land Mobile Radio When do LMR Systems Fail? • 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
Private Land Mobile Radio What Happens to First Responder Communication Systems? • 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
Private Land Mobile Radio Where Can We Improve Survivability? • 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

Private Land Mobile Radio LMR Radio System Coverage – Illinois Starcom 21 Network • Denser site configuration; more RF saturation • More overlap between sites, including simulcast cells in the urban areas • Individual site failures have less impact
Private Land Mobile Radio IBWA - In Building Wireless Alliance • 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
Private Land Mobile Radio Enhance LMR Communication Site Standards • 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

Private Land Mobile Radio Network Operations Centers • Remotely monitors LMR system health • most do not have this service • Staffed 24/7 • Knowledge database of approved solutions • System labs for problem replication • Access to system platform architects • Automated escalation management system • Quality review process • Remote system software downloads • National Communication System collaboration
