Denso Ten UWB Wireless Interference Suppression Technology Adopted into IEEE 802.15.6-2026 Standard

Denso Ten Limited. announced on June 24 that its proposed Ultra-Wideband (UWB) wireless interference suppression technology has been incorporated into the international IEEE 802.15.6-2026 standard. The milestone supports the company's long-term strategy to replace conventional in-vehicle wiring harnesses with wireless communication, helping reduce vehicle weight, optimize installation space, and conserve resources. Through this achievement, the company intends to strengthen collaboration with UWB chip manufacturers and other industry partners to accelerate commercialization and deployment across next-generation mobility solutions.

A Body Area Network (BAN) is a wireless communication network that connects multiple in-vehicle devices or wearable components, including sensors and actuators. When several BANs operate simultaneously in close proximity, radio interference between networks can create communication delays and unstable data transmission. To address this challenge, Denso Ten developed a solution based on the quasi-orthogonality of UWB communication frame preambles, allowing multiple BANs to communicate simultaneously while minimizing interference. The technology also reduces communication waiting time, enabling low-latency operation and maintaining stable communication cycles.

The wireless communication approach offers benefits beyond reliable connectivity. By replacing sections of traditional wiring harnesses, manufacturers can reduce overall vehicle weight, improve packaging efficiency, and increase flexibility during vehicle development. These advantages also enhance scalability, making it easier to integrate additional electronic systems as vehicle architectures continue to evolve. The technology supports future mobility platforms that demand efficient communication between a growing number of connected electronic components.

As commercialization progresses, Denso Ten Limited. plans to use wireless harness replacement as the foundation for broader product development. The company also intends to expand this technology beyond in-vehicle applications by targeting aftermarket solutions for Software-Defined Vehicles (SDVs). These initiatives are expected to support future mobility ecosystems through more efficient wireless communication while creating opportunities for applications extending beyond the automotive sector.
