IEEE Standards Association

The IEEE Standards Association has announced the formation of two new study groups to advance and accelerate wi-fi technology.

The groups IEEE Broadcast Services and the Next Generation V2X Study Groups will amend the organisations' IEEE 802.11 standard commonly referred to as wi-fi.

The Next Generation V2X Study Group will focus on how to support recent 802.11 technologies to address new applications of wireless access in vehicular environments.

The group aims to come up with new requirements for higher throughput, improved reliability and efficiency, as well as extended range.

Bo Sun, chair of the Next Generation V2X Study Group, said: "To support advancements in driverless car technology, car-to-car and car-to-infrastructure connectivity, as well as to enable more robust vehicular infotainment offerings, a higher, more reliable and efficient throughput as compared to IEEE 802.11p is foreseeable.

“Stakeholders involved in vehicular applications are encouraged to lend their voice in helping advance IEEE 802.11 so that the standard meets all anticipated future requirements in order to increase its adoption in this rapidly expanding market.”

The IEEE Broadcast Services Study Group is exploring new use cases for simultaneously broadcasting local information over IEEE 802.11 WLAN without recipients needing to actively connect to an access point.

The group will enhance security features as well.

Applications include broadcast of local information such as vehicular traffic updates, parking availability, emergency information or information from IoT devices at events, shopping malls, tourist attractions, train stations and airports.

Marc Emmelmann, chair, IEEE Broadcast Services Study Group, commented: “The ever-increasing data and information demands driven by a broadly-connected and mobile public, as well as IoT devices, offers unique opportunities for new local broadcast applications using IEEE 802.11.

“While we have seen a good initial response from stakeholders, and an interesting exploration of new use cases, we encourage broader participation so that we can work towards defining a project that addresses all relevant aspects for achieving the most beneficial results for expanding broadcast services utilizing IEEE 802.11.”
