Roadmap Principles

•Dispatchable Location

•Open, Transparent Testing

•Better Lat/Long, Standard Confidence

•Enforceable Metrics and Fallbacks

What Isn’t Changing

•Latitude / Longitude / Uncertainty

•ALI Formats

•MSAG / LVF Validation of Addresses

•Best estimate available from network

Improving L/Lo Tech

•Carriers will deploy O-TDOA ,A-GNSS, and hybrid network-wide.

•New VoLTE phones will support both.

•Carriers crowd-sourced WiFi & Bluetooth X/Y in ~36 months.

true position

Uncertainty “u” is proportional to the confidence factor “c”.

o The smaller the confidence percentage, the shorter the uncertainty distance.

o The larger the confidence percentage, the longer the uncertainty distance.

Standard Confidence

Test Bed

•Permanent test-bed for DL & X/Y/Z

•Objective, Transparent, Open, & Public-Safety Inclusive

•Representative of all morphologies(Dense Urban, Urban, Suburban, Rural)

16

Test Bed

•Quantify the “art of the possible.”

•Characterize the performance of technologies.

•Provide “compliant fractions” to assess live-call data.

17

Test Bed

•Two Locations:◦San Francisco◦Atlanta

•Provides a mix of construction types, structure density, and topology.

18

Performance Metrics

6 “Monitored Markets”19

Performance Measurement

• Aggregated monthly, reported quarterly.

• Fraction of fixes by technology.

• PSAPs can get positioning source data!

• 9-1-1 Authorities must work with carriers to resolve performance issues before seeking FCC enforcement actions.

20

Performance Requirements

DL or ≤ 50m Technology for:◦40% of all wireless 9-1-1 calls within 2 years

◦50% “ “ “ “ “ “ “ 3 years

◦70% “ “ “ “ “ “ “ 5 years

◦80% “ “ “ “ “ “ “ 6 years21

Vertical Information

22

Vertical Location Information

•Within 6 years, carriers must, for each of the top 25 Cellular Market Areas (by population) deploy either:◦ 1 DL reference point for every 4 residents; or

◦ Z-Axis technology covering at least 80% of the population.

23

Formal Evaluation

•NENA and APCO continuously evaluate carrier performance and adherence to timelines.

•Reasonable variations (e.g., standards development cycles) are expected, but will be monitored.

•At 36 months, a major assessment will determine whether the development and deployment of Dispatchable Location technology is “on track.”

•If not, carriers must supplement DL with Lat/Lon and Altitude technologies.
