White Paper Overview

Ultrawideband (UWB) is a radio technology operating in the unlicensed spectrum for near-field communications with low power consumption and low complexity at low cost.

UWB has existed for quite a long time and was mainly used for traditional radar imaging without a ratified communications standard for worldwide deployment until it was authorized for the first time in 2002 by the American Federal Communications Commission (FCC). In addition to the FCC, the Institute of Electrical and Electronics Engineers also later elaborated UWB standardization. Since then, UWB technology has grown in commercial importance for short-range data communications as well as high-accuracy ranging applications.

Read this white paper to get an overview of UWB physical layer fundamentals, the associated test requirements and appropriate test solutions. The paper covers several topics including:

  • UWB standards and international UWB consortia
  • Technical fundamentals of UWB technology
  • The high rate pulse (HRP) UWB physical (PHY) layer based on the IEEE 802.15.4 standard as well as the IEEE 802.15.4z standard
  • The ranging technique and location method of UWB
  • Test aspects of UWB devices with respect to the physical layer and ranging function, followed by a summary of R&S test solutions for UWB PHY verification
