Abstract: We describe an advanced mobile channel sounder system that has been under development by engineers at NTIA’s Institute for Telecommunication Sciences since 2010. We provide a description of the channel sounder and the key system components. We then highlight the flexibility and power of this system by showing a variety of measured and processed radio propagation results obtained using this system. This system has been deployed in numerous outdoor and indoor propagation measurement campaigns. This system has also been used for both in-building and building penetration measurements.
