Intelligent Transportation Systems © 3M 2001 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 /

Intelligent Transportation Systems © 3M M’s interest in GPS repeaters (or re-radiators)  For use in conjunction with Opticom™ GPS system

Intelligent Transportation Systems © 3M M’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

Intelligent Transportation Systems © 3M 2001 Implementation of 3M’s proposal will:  Significantly contribute to safety of life and property  Satisfy the concerns of regulators

Intelligent Transportation Systems © 3M M is seeking experimental authorization to:  Demonstrate equipment to prospective purchasers  Test equipment – obtain regulatory approval  Conduct field studies to evaluate interference potential

Intelligent Transportation Systems © 3M 2001 Opticom™ GPS system features  Controls traffic signal priority  Does not disrupt normal traffic flow

Intelligent Transportation Systems © 3M 2001 Need for GPS repeaters  Emergency vehicles must acquire GPS signal quickly  GPS signal provides location and timing synchronization

Intelligent Transportation Systems © 3M 2001 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

Intelligent Transportation Systems © 3M 2001 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

Intelligent Transportation Systems © 3M 2001 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!

Intelligent Transportation Systems © 3M 2001 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

Intelligent Transportation Systems © 3M M’s use of GPS repeaters would be within present regulatory limitations  Radiation below level permitted by FCC for spurious emissions

Intelligent Transportation Systems © 3M 2001 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

Intelligent Transportation Systems © 3M 2001 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

Intelligent Transportation Systems © 3M M 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

Intelligent Transportation Systems © 3M 2001 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

Intelligent Transportation Systems © 3M 2001 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
