  1. Presentation of 3M Company for the Special Meeting of the IRAC on GPS Repeaters October 28, 2005 by Harold Mordkofsky Blooston, Mordkofsky, Dickens, Duffy & Prendergast 202-828-5520 / halmor@bloostonlaw.com

  2. 3M’s interest in GPS repeaters (or re-radiators) • For use in conjunction with Opticom™ GPS system

  3. 3M’s proposal will include restrictions on use and operation • GPS repeaters will not fall into the wrong hands • Use will not compromise conventional GPS equipment • Use will not cause interference to other GPS users

  4. Implementation of 3M’s proposal will: • Significantly contribute to safety of life and property • Satisfy the concerns of regulators

  5. 3M is seeking experimental authorization to: • Demonstrate equipment to prospective purchasers • Test equipment – obtain regulatory approval • Conduct field studies to evaluate interference potential

  6. Opticom™ GPS system features • Controls traffic signal priority • Does not disrupt normal traffic flow

  7. Need for GPS repeaters • Emergency vehicles must acquire GPS signal quickly • GPS signal provides location and timing synchronization

  8. How the 3M Opticom™ GPS system works • Transmitter on emergency vehicle sends 2.4 GHz signal • Receiver near intersection converts signal to electronic communication • Phase selector in controller cabinet request priority advantage to control traffic light • Traffic light turns green as emergency vehicle approaches intersection • GPS repeater assures that all of this takes only seconds from start of run

  9. How the 3M Opticom™ GPS system works • Emergency vehicles shielded from GPS signal since housed in closed buildings • Use of GPS repeater allows vehicle to be “locked on” to GPS signal at all times

  10. Without GPS repeater, acquisition of GPS signal is delayed by: • Time to start up vehicle and exit the building • Shielding from trees, tall buildings and other obstacles • Critical delay of up to five minutes before emergency vehicle could lock on to GPS signal • Precious time may be lost in emergency circumstances!

  11. 911 Emergency ResponseManagement – Travel and Response Time Before 4 minutes 42% survived After4 minutes7% survived 1 2 3 4 Time InMinutes 0% minutes Survival Rate – Cardiac Arrest Cole and Corday “Four-minute Limit for Cardiac Resuscitation”

  12. Flashover 911 Emergency ResponseManagement – Travel and Response Time Fire test jointly conducted by Factory Mutual Research and Harvard University

  13. Typical GPS repeater installation: • GPS repeater in building in view of vehicle • EIRP limited to -140 dBm at 100 ft. • With 3 dB antenna, ERP limited to 39.8 pW • Notification to FCC of particulars of operation • location, number of units • power, emission designator • any other information deemed pertinent

  14. 3M’s use of GPS repeaters would be within present regulatory limitations • Radiation below level permitted by FCC for spurious emissions

  15. Adherence to NTIA policy objectives: • Individual license for each GPS repeater • FCC will have full particulars of operation • No operation for more than six months without regular license • Use of GPS repeater terminates if any reported interference cannot be eliminated • Two-year license term and listing of approved sites in accessible database

  16. Potential interference is strictly limited • Use under control of public safety officials – well known in their communities. • Other users of GPS notified of use of GPS repeaters • “Stop buzzer” phone no. available 24/7 • GPS repeater shuts down pending investigation and remediation • Other emergency uses of GPS not compromised

  17. 3M will provide periodic reports as requested by FCC • Proposed use of GPS repeaters will contribute to development of standards • Will provide federal government with valuable information

  18. Summary • Proposal strictly tailored to limit use and avoid interference • Will operate inside buildings • Will operate at lowest power possible • Will be under supervision of local government public safety officials

  19. Summary • Use of GPS repeaters will save lives! • serves an important function of FCC’s regulation of radio • 3M will institute rulemaking based on information developed during experimental operations
