IEEE 802.15.4ab: Unlocking UWB’s true potential

Ultra‑Wideband (UWB) is on its way to becoming a major wireless technology, with ABI Research expecting it to be one of the fastest‑growing connectivity options between 2025 and 2030.

The upcoming IEEE 802.15.4ab (next‑generation UWB) standard will enhance the user experience, supporting hands‑free car access under any conditions, and help carmakers meet new safety regulations, including child presence detection.

What's inside the ABI research whitepaper?

In this whitepaper by Andrew Zignani, Senior Research Director at ABI Research, discover how IEEE 802.15.4ab will:

• Improve reliability with a higher link budget, so devices can be located more easily in difficult situations (such as when a phone is in a back pocket).
• Cut power consumption by starting localization only when it is really needed
• Reduce interference and congestion so many users can use ranging at the same time without conflicts
• Maintain high accuracy with single, precise measurements that still work well even without a direct line of sight.
