The IEEE has announced the formation of a new study group to consider initiating a formal project to standardize Power over Data Lines (PoDL) technology. The IEEE 802.3 1-pair Power over Data Lines (1PPoDL) Study Group will consider a new single-pair, Ethernet-based powering standard, especially aimed at providing automotive and industrial networking applications with cost- and energy-efficient network architecture.
“PoDL will extend the benefits of Power over Ethernet (PoE) to vehicular and industrial networking environments that use single-pair Ethernet links, such as the IEEE P802.3bp Reduced Twisted Pair Gigabit Ethernet (RTPGE) standard under development," comments Dave Dwelley, chair of the 1PPoDL study group and product line manager for mixed signal products at Linear Technology.
"This is similar to the way that PoE introduced power into structured cabling-based networks,” adds Dwelley. “Vehicles and other forms of transportation are rapidly turning into mobile data centers and will require a network infrastructure that accounts for weight and cost. PoDL technology provides these capabilities.” Individuals interested in the future of PoDL standards are invited to contribute to the new study group, which is scheduled to meet for the first time on 2-3 September 2013 in York, UK.

“We’re very much enabling the Internet of Things (IoT) with the combination of this proposed PoE technology and the IEEE P802.3bp RTPGE standard under development,” says David Law, chair of the IEEE 802.3 Ethernet Working Group and distinguished engineer with HP Networking. “This would provide the ultimate combination for low-cost powered, high-data throughput sensor communications technology.”
Adds Wael William Diab, vice chair of the IEEE 802.3 Ethernet Working Group and senior technical director with Broadcom, “We’re basically enabling Ethernet to go places where it hasn’t gone before. In the age of IoT, PoDL technology enables intelligent and connected vehicles. Backup cameras, automated parking systems and self-driving vehicles demand very large amounts of onboard data equipment that require links to enable communication. With the help of Ethernet, we’re seeing a convergence in ubiquitous connectivity in these markets.”
