Wireless E911 Overview and Status Update

1. Wireless E911 Overview and Status Update David Woodcock Director, Product Management Motorola Canada PCS david.woodcock@motorola.com

2. FCC E911 Mandate This year* • 100m accuracy for 67% of calls • 300m accuracy for 95% of calls Phase 2* • 50m accuracy for 67% of calls • 150m accuracy for 95% of calls Subscriber Activations* • Certain % of new adds must be location-capable *Exact dates and mandate vary by carrier

3. Position Determination Options Assisted GPS Network-Based E-OTD/AFLT GPS Sat Location Calc & Control Location Calc & Control GPS Assist Serving Cell Serving Cell Serving Cell Neighbor Cell # 1 Neighbor Cell # 1 MS Synchronized Sites or LMU’s MS MS Wideband or Scanning Receivers Neighbor Cell # 2 Neighbor Cell # 2 • Technologies • TDOA (3 sites minimum) • AOA (2 sites minimum) • Multipath “Fingerprint” (1 site minimum) • New site equipment • Legacy handset are supported • Handset modifications • Memory • A-GPS Integrated Chip Sets • Second Antenna • Software • 1 site + 3 GPS Sat solution • New network boxes • Legacy handsets not supported • Handset modifications • Software • Memory • TDOA (3 sites minimum) • May require new site equipment & network boxes • Legacy handsets not supported

4. MLC MLC Cell ID EOTD, AFLT GPS (Auto) A-GPS (Assist) HS Changes None Software SW + HW SW + HW Added Cost None Low High High Accuracy 100-1000 m (Cell) 75- 300 m 15-150 m 1-100 m TTFF < 5 Sec 5-20 Sec 10-60 Sec <5 Sec Increase in Accuracy Increase in Coverage (Dense Urban, Valleys, Indoors) How they compare Increase Accuracy

5. Hybrid: EOTD / AFLT Network sends a burst message to the handset Handset calculates time differentials & reports back. Network calculates handset position

6. Hybrid: AGPS Network provides assistance data to handset to limit satellite acquisition times. Handset receives GPS data from satellites (three required for position determination) Assistance data GPS Handset reports ‘pseudo-ranges’ to network for position determination. Pseudo-ranges Network calculates handset position

7. Pros Minimum Network Impact Greater Subscriber Privacy? Proven High Degree of Accuracy Using GPS Less network maintenance Handset vs. Network Based Network Handset • Pros • Ability to Deploy • on an as Needed Basis • Addresses Legacy Phones and Roamers • Cons • Legacy Issue • Handset size, cost, battery life • GPS antenna issues • Cons • More Site Antennas or new sites may be Required in Some Areas • Additional Equipment At Cell Site • Large Initial Capital Requirement • Calibration and additional maintenance

8. U.S. Carrier Plan of Record U.S. Carriers have selected handset-based solutions

9. Motorola Handset Roadmap GSM/GPRS • Several EOTD-capable products launching in 2H02 • All future products will have EOTD CDMA/1X • One AFLT handset launching in June • Three AGPS handsets launching in 2H02 • All future products will have AGPS Multiple hardware and software solutions available for EOTD / AGPS

10. Then What? Carrier network must calculate and report location to PSAP “Push” – if location information is available at call-setup “Pull” – if not available initially, or to update location information during call PSAPs must be ready to integrate ALI from wireless devices

11. Issues… Relevance • Does the (mobile) location data have any meaning? • How current is it? (street addresses can’t move…) Accuracy • Performance in urban and rural areas • Satellite acquisition / multi-path signals • Cell site separation Privacy • Do users really want to be found? • Users have ability to disable location service except during 911 calls The challenge goes beyond technology

12. Handset capabilities are just the foundation Data Usefulness PSAP capabilities Network location determination Handset location capabilities Many bricks needed to build the structure
