1 Planning for Connectivity in a Maturing Connected Environment Presented by Tom Timcho OTEC /11/17

2 What is Connectivity? Vehicles talking to Vehicles (V2V) Vehicles talking to Infrastructure (V2I) Vehicles / Infrastructure talking to Mobile Devices / People (V2P) Vehicles talking to the Network (V2N) Source: 5G Americas

3 Why is this Important? Save Lives Increase Mobility Reduce Environmental Impact Convenience Status Symbol Quality of Life

4 Technologies to support Connectivity 3G 4G/LTE a/b/g/n Wi-Fi Dedicated Short Range Communications (DSRC) Satellite 5G Bluetooth, ZigBee & Others

5 Technologies to support Connectivity 3G 4G/LTE a/b/g/n Wi-Fi Dedicated Short Range Communications (DSRC) Satellite 5G Bluetooth, ZigBee & Others

6 Considerations Latency is it fast enough to support the need? Coverage is it available when you need it? Cost how much does it cost? Security can I trust the data I receive? Privacy who owns my data?

7 4G / LTE Consideration Discussion Latency Coverage Cost Security Privacy Other Very good but generally not capable to support safety-of-life Very good in most urban areas $20/mo. or more Uses current Internet standards All data passes thru the carrier No direct device-to-device capability

8 DSRC Consideration Latency Coverage Cost Security Privacy Other Discussion Supports safety-of-life Test or Pilot Sites only / Only GM including on Vehicles No recurring cost to user By design (IEEE x) By design DSRC users are anonymous Carriers want access to spectrum

9 Satellite Consideration Latency Coverage Cost Security Privacy Other Discussion Good, at best. Limited ability to support real-time Nationwide when clear view of sky / vehicle market approaching 90% Est. $15/mo. or more Uses current Internet standards All data passes thru the carrier One-Way Communication

10 5G / 5G Direct Consideration Discussion Latency Coverage Cost Security Privacy Other Claimed to be able to support safety-of-life TBD but expected to be very good in most urban areas TBD - but expected $20/mo. or more Uses current Internet standards All data passes thru the carrier? Supports a Device-to-Device model

11 Current CV Plans in Columbus

12 USDOT CV Applications

13 Forward Collision Warning (V2V Safety) Need: Delivery Vehicle Location/Speed/Trajectory Data to surrounding vehicles Constraint: Latency < 50ms Candidates: 4G No Device-to-Device support DSRC Demonstrated Success Satellite Use Case Not supported 5G Under best case conditions? 5G Direct Expectation is Yes

14 Red Light Violation Warning (V2I Safety) Need: Delivery Signal Phase and Timing Data from Traffic Signal to Approaching Vehicle Constraint: Latency < 50ms Candidates: 4G Informational Only DSRC Demonstrated Success Satellite Not supported 5G Under best case conditions? 5G Direct Expectation is Yes

15 Queue Warning (V2I Mobility) Need: Determine back-of-queue information from vehicles and convey location to drivers Constraint: Assume vehicle contributes to data pool Candidates: 4G Demonstrated Success DSRC Demonstrated Success Satellite Supports information dissemination only 5G Yes (based on 4G results) 5G Direct Expectation is Yes

16 Pedestrian Safety (V2P) Need: Inform vehicles of VRU in proximity Constraint: low-latency Candidates: 4G Not supported DSRC Demonstrated in limited success Satellite Not supported 5G Under best case conditions? 5G Direct Expectation is Yes

17 Eco-Driving (V2N) Need: Inform driver of recommended speed to maintain optimal traffic flow / emissions reduction Constraint: requires SPAT data Candidates: 4G Demonstrated Success DSRC Demonstrated Success Satellite Not supported 5G Yes (based on 4G results) 5G Direct Expectation is Yes

18 What does this mean? Only DSRC and 5G-Direct support Safety-of-Life Applications Limited by penetration of equipped vehicles and infrastructure Mobility & Eco-Driving Apps Available now via 4G / Satellite (limited) DSRC and 5G should support in future

19 DSRC Assessment Ready now waiting on NHTSA Rulemaking No-cost to the end-user Designed to be anonymous However, aging technology and spectrum is of value to others

20 5G / 5G Direct Assessment Expected to become as widespread as current footprint Will be part of handheld devices However, Carriers are incentivized by profits 4G shows that a single system has yet to be codified

21 Role of Satellite Augment low-latency technology with nationwide coverage

22 Summary Connectivity will continue to progress the promise is too great not too. Both DSRC and 5G will be dependent on backhaul connectivity and vertical assets Agencies need to leverage these assets they are valuable Consumers must wait and see
