A method for interoperations between single-radio (channel switching) devices and single-radio (always-on) devices includes single-radio (always-on) devices keep announcing safety messages on the safety channel at any time and keep monitoring packet transmissions on the safety channel at all times when it not transmitting in a normal mode; single-radio (channel switching) devices announce safety messages on the safety channel and keep monitoring packet transmissions on the safety channel during a safety channel interval; and once a single-radio (always-on) device detects the existence of a single-radio (channel-switching) device after successfully receiving at least one safety message transmitted by the single-radio (channel-switching) device during the safety channel interval, it enters to an interoperation mode, in which the single-radio (always-on) device shall transmit safety messages at least during the safety channel interval of the single-radio (channel-switching) device. Methods for interoperations between single-radio devices and dual-radio devices, with and without a safety channel are also disclosed.
