WEMA10: Performing Large OTA Data Collections with the USRP

Presentation Abstract
This MicroApp provides a practical guide for performing real-time over-the-air (OTA) data collections (recordings) for large data sets with USRP SDR radios for applications such as spectrum monitoring and AI/ML. We will consider the performance and capability tradeoffs between the various USRP devices, and discuss practical considerations regarding antennas, power levels, data rates and sampling rates, data word width, CPU I/O and disk I/O, and Ethernet connectivity. We will also examine the SigMF and DigitalRF file formats for storing and organizing data, as well as how to use the RF Data Recording API to automate large data collections.
