Proposal for Data Offload Using WLAN in Connected Vehicle Scenario
Explore a proposal for WLAN data offload in connected vehicles, addressing gaps in IEEE standards to meet automotive requirements. Discuss potential use cases, gaps, and essential requirements for efficient data transfer between vehicles and the cloud. Previous presentations to WNG have highlighted the necessity for faster network discovery, seamless handover, and optimized roaming algorithms to enhance WLAN data offload in automotive applications.

July 2024 doc.: IEEE 802.11-24/1134r1 Proposal on Data offload using WLAN in connected vehicle case Authors: Name Jing Ma Affiliations Toyota Motor Corporation Address 1-6-1 Otemachi, Chiyoda-ku, Tokyo, 100-0004, Japan Phone email jing_ma@toyota-tokyo.tech Jing Ma (Toyota)
July 2024 doc.: IEEE 802.11-24/1134r1 Abstract Needs, example use cases, potential gaps between current IEEE specification and the requirements of WLAN data offload for automotive have been introduced [1~2] We propose to form a Topic Interest Group (TIG) to discuss use cases, requirements and technical concepts and 802.11 standard gaps related to WLAN Data Offload for Automotive (WDOA) 2 Jing Ma (Toyota)
July 2024 doc.: IEEE 802.11-24/1134r1 Background Connected vehicles have become large procurers and consumers of data 100 petabytes of data is transferred to the cloud monthly Camera generates data (500~3500) Mbit/s/camera RADAR generates data (0.1~15) Mbit/s/RADAR Offloading data from cellular to WLAN may offer a faster and more cost-effective solution for connected vehicles Requirements such as fast association & authentication, seamless AP handover, optimized roaming algorithm, etc., are essential for WLAN data offload for automotive However, current IEEE standards still has gaps to satisfy the WLAN data offload for automotive 3 Jing Ma (Toyota)
July 2024 doc.: IEEE 802.11-24/1134r1 Applications WLAN can provide efficient local connectivity for transferring large amounts of data between vehicles and the cloud for automotive applications such as Reginal HD Maps and remote diagnostics. Core & network Local data exchange between vehicle and WLAN AP Remote Diagnostics Data center Reginal HD MAP 4 Jing Ma (Toyota)
July 2024 doc.: IEEE 802.11-24/1134r1 Previous WNG presentations Several presentations have been made to WNG on WDOA At the March session (2): 24/415r1 At the May session (1): 24/793r1 These presentations have introduced the needs, example use cases, potential gaps between current IEEE specification and the requirements of WDOA 5 Jing Ma (Toyota)
July 2024 doc.: IEEE 802.11-24/1134r1 Previous WNG presentations Summary of the initial gap analysis [2] Requirements Relevant current IEEE802 specifications 11u Relevant features Gaps Network discovery/ selection ANQP, etc. No faster network discovery, selection Link unstable on the move may cause delay on link setup, failure on handover Fast association & authentication Seamless handover among APs 11ai FILS 11r Fast BSS Transition 11k Radio Resource Measurement Seamless roaming, etc. 11bn It s clear that our initial gap analysis is far from complete for the automotive industry to follow. Jing Ma (Toyota)
July 2024 doc.: IEEE 802.11-24/1134r1 WLAN Data Offload for Automotive: scope of work Discuss contributions in the areas of, but not limited to: Use cases and requirements Key performance indicators Technical approaches and 802.11 standard gaps in the areas such as protocols in association & authentication, seamless AP handover, optimized roaming algorithm etc. Alternative solutions These discussions will inform the TIG on the need and timing of requesting formation of a SG at a future 802.11 meeting Slide 7 Jing Ma (Toyota)
July 2024 doc.: IEEE 802.11-24/1134r1 Straw poll Do you agree to form a TIG of WLAN Data Offload for Automotive (WDOA) to investigate use cases, requirements, technical approaches and 802.11 standard gaps to support requirements. Y N A Slide 8 Jing Ma (Toyota)
