The O-RAN Alliance brings together mobile network operators, equipment manufacturers, device makers, and chipset suppliers to create standards and recommendations for an open radio access network (RAN). Building a more cost-effective, agile RAN requires openness. Open interfaces are essential to enable small-scale vendors to introduce their own services quickly and facilitate multi-vendor deployments and a more competitive supplier ecosystem.

Although it’s been around for some time now, ultra-wideband (UWB) is considered the new “location technology” kid on the block, and it’s growing at a healthy pace. To fully understand it, it’s helpful to look at how it originated, the role it plays, how it works, and the use cases it powers. This article looks at the history of location technology and explores the solutions that led to the pin-point, real-time accuracy of UWB.

Rohde & Schwarz GmbH & Co. KG
Ultra-wideband (UWB) technology has a growing number of applications in communication technology, radar sensors, or IoT equipment, among many others, all using an extremely high bandwidth of 500 MHz or more. The ETSI standard requires in-band testing for product certification with a resolution bandwidth of 50 MHz. This application note explains technical reasons for the bandwidth limitation and presents solutions for regulative UWB testing.
