  1. Wireless E911Technology RoundtableJune 28, 1999KSI Inc.Dr. John E. Maloney

  2. KSI Background • Tech staff: Development of localization & tracking (L&T) systems since 1971 • CMRS LDS/PDE development • 1986... IP development • 1990... Experimental prototype demonstrations • 1994... NPRM support with data results • AMPS: access/control & traffic/voice signals • 1997 External investment/capitalization • Advanced data results • 1998 DAMPS/TDMA & AMPS • 1999 Preliminary rural • CMRS management: COB & CEO, COO, VP

  3. Myth-Statements vs. Reality • Misstatements re. TeleSentinel™ network/infrastructure characteristics

  4. Air Interface Support • TeleSentinel™Development

  5. Network LDT Benefits • Infrastructure-based LDTs: • Locate all phones, old, new, and future • Accommodate all air interfaces, NAMPS through 3G • Support all services, E911, commercial, and communications • Provide security, personal and public

  6. Issues • Location of AMPS handsets(Proc'g & info. messages vs. e.g. CDMA) • E.g., Rural environments • Latency time for selective routing to the designated PSAP • E.g., Assisted GPS: 20 sec (goal: 6 sec) • High-percentage Phase II E911 service • CEP for 50% or 67% vs. RMS (e.g., for 90%)
