An example system includes a sensor and a transceiver coupled to the sensor, the transceiver including: an oscillator circuit including a thin-film bulk acoustic resonator (FBAR), and an antenna. The system also includes a controller with a processor programmed to: broadcast, by the antenna, a first data packet on a wireless channel, where the first data packet is a first packet of a broadcast event; receive, at the antenna, a second data packet transmitted on the wireless channel, where the second data packet is a second packet of the broadcast event; and responsive to receiving the second data packet, perform an action associated with the broadcast event; responsive to the action, transmit, by the antenna, a third data packet on the wireless channel, where the third data packet is a third packet of the broadcast event.
