1. A radio frequency system for performing radio frequency based sensing based on multiple communication technologies,
the radio frequency system comprising multiple radio frequency devices each configured, in order to detect sensing events, for performing radio frequency based sensing by transmitting and receiving radio frequency signals using a single-channel communication technology and further configured for performing radio frequency based sensing by transmitting and receiving radio frequency signals using a multi-channel communication technology,
wherein the radio frequency system is configured for determining a single-channel confidence level for detecting a sensing event by performing radio frequency based sensing using the single-channel communication technology, and
wherein the radio frequency system is configured upon detecting that the single-channel confidence level is above a first single-channel threshold level and below a second single-channel threshold level which is higher than the first single-channel threshold level:
to select a multi-channel communication technology for performing radio frequency based sensing based on one or more radio frequency system criteria, and
to perform radio frequency based sensing by transmitting and receiving RF signals using the multi-channel communication technology.
