CMP200

The UWB (Ultra-Wide Band) technology is a low power wide-band technology specified for device to

device communication. It is an optimal RF positioning technology that enables accurate and secure peer-

to-peer distance measurement between mobile devices with robust resistance to interference while

consuming very low energy and coexisting well with other radio communication systems.

This application note describes how to use the UWB measurement functionality provided by R&S

CMP200

radio communication tester to perform HRP UWB PHY measurements for R&D and production purposes.
