Ultrawideband (UWB), a low-power, low-cost radio technology for near-field communications and high-accuracy ranging applications has grown in commercial importance for short-range data communications and is used in various market segments such as telecommunications, automotive, banking, healthcare, and the public sector. It is estimated that 80% of smartphones and related accessories and 11% of car access devices will be equipped with UWB technology by 2025. This white paper introduces UWB physical layer fundamentals, the associated test requirements and appropriate test solutions.
This white paper covers the following topics:
- Introduction to the UWB standards and international UWB consortia
- Technical fundamentals of UWB technology
- High rate pulse (HRP) UWB physical (PHY) layer based on the IEEE802.15.4 standard
- IEEE802.15.4z standard
- UWB ranging technique and location method
- Testing aspects of UWB devices with respect to the physical layer and ranging function
