1 V2X: Beyond the Horizon IBTTA AET Meeting July 18, 2017

2 Battle over V2X Technology: DSRC vs 5G 18 July

3 Dedicated Short Range Communication (DSRC) Bi-directional wireless communications permitting secure and fast messaging needed for safety applications. These communications occur in a 75 MHz band of the 5.9 GHz spectrum Vehicles communicate with each other by passing and interpreting messages Vehicles disseminate Basic Safety Messages (BSM) 10x a second based on the SAE J2735 Standard A vehicle that receives the message processes the data and assesses collision threat that in turn and triggers either an automatic response or driver warning Roadside Units (RSU) On-Board Unit (OBU) 18 July

4 Cellular V2X (C-V2X) C-V2X communications is an emerging technology that works off of LTE (Long- Term Evolution) features and cellular networks to provide V2X capabilities Supports Direct Communications (V2I/V2V/V2P) independent of cellular networks based on PC5 interface using 5.9 GHz Also supports Vehicle to Network (V2N) applications for longer-range interactions Source: Qualcomm 18 July

5 Comparison Advantages DSRC Established technology, Low Latency Capable of functioning at high speeds and adverse weather conditions Global harmonization of standards Disadvantages Range Limited to 1000 m Requires OBU and RSU to be deployed No evolution path Advantages C-V2X Envisioned to support IoT and Smart Cities More reliable at high speeds and long ranges Does not require separate OBU Disadvantages Evolutionary, not expected until 2020 Questions about connectivity / lack of coverage in rural/sparse areas Privacy concerns as data is passed through cloud 18 July

6 Legal Battle over V2X FCC ET Docket No (reconcile use of 5.9GHz between DSRC & Wi-Fi) Detect and Vacate - DSRC and Wi-Fi would share the spectrum, unlicensed devices would detect DSRC operations and vacate the spectrum (Proposed by CISCO, Supported by the ITS and Auto industry) Rechannelization Split the DSRC into 2 contiguous blocks (Proposed by Qualcomm, Supported by other blocs) NHTSA NPRM: 49 CFR Part 571 / Docket No. NHTSA Mandate DSRC vehicle-to-vehicle (V2V) communications for new light vehicles and to standardize the message and format of V2V transmissions 18 July
