New ITS America Report Re-examines the Challenges of Wireless Interoperability and Vehicle Connectivity

Findings Suggest Vehicle Applications to Benefit from
Standards for Heterogeneous Networking

Washington, D.C. (November 5, 2014) – A new report released today by the Intelligent Transportation Society of America (ITS America) investigates how heterogeneous mobile broadband networks could enable interoperability between next generation vehicle and road infrastructure applications.

Automakers, transportation agencies, and others have for more than a decade lamented the lack of wireless interoperability between disparate Intelligent Transportation Systems (ITS), such as tolling, traffic control, and vehicle remote diagnostics. The emergence of Dedicated Short-Range Communications (DSRC) solved the largest part of this interoperability problem — specifically in reference to life-saving next generation vehicle safety technologies such as crash avoidance systems.

The report titled, Vehicle Applications and Wireless Interoperability: Heterogeneous Networks, “Multi-Path” Applications and their Impact on Transportationemphasizes that a new open internetworking standard is emerging to address interoperability of dissimilar mobile broadband networks– the Multi-path Transmission Control Protocol (Multi-path TCP).

Apple Inc. recently implemented a variant of the Multi-path TCP in its iOS operating system to support the intelligence personal assistant and knowledge navigator application Siri, enabling it to utilize Wi-Fi and cellular connections simultaneously and improve its robustness responding swiftly to voice queries. Apple CarPlay, released in 2014, is version of iOS designed to function with built-in automobile dashboards. Other companies are likely to use the same open standards to follow suite.

“New internetworking standards may erase distinctions between specialized wireless systems,” said ITS America Senior Technical Program’s Specialist Adrian Guan. “Such standards, if widely adopted, will allow apps, in particular traveler mobility apps, to choose the best network based upon service availability, unlimited by the type of radio technology.”

The Multi-path TCP protocol maintains simultaneous Internet Protocol (IP) connections across different radio networks to cloud based apps that are robust to roaming – leaving radio coverage areas and entering new hotspots – without breaking the connection. The report suggests that Multi-path TCP may be incorporated in a future Connected Vehicle environment to allow some DSRC mobility applications to utilize and roam across hotspot coverage areas. The report examines the opportunities and some of the remaining challenges to such heterogeneous networking in ITS.
