Radio Bursts in Residences During COVID-19: Measured Characteristics for Resiliency Testing

We present an analysis of the time parameters observed in radio spectrum occupancy measurements of 13 residential sites from June 2020 through September 2021. The focus of the analysis is on implications for electromagnetic immunity testing of medical devices and household electronics. We demonstrate that the bursted nature of household transmissions, together with wide gap times between transmissions, stands in significant contrast to the continuous periodic disturbances used in immunity testing. Further, we identify that the most active band, 2.4GHz, is not yet prescribed as a test frequency in all immunity standards.
