All the time, as in several times per second. I have a bluetooth sniffer and these beacons are very very chatty. I didn't test the AirTags myself but it can't be lower than once every 5 seconds or so. But really I think they are like the other battery-operated BLE beacons with several times per second. BLE really is really low energy, they got that part totally licked. The expected distance is pretty high. Officially up to 10m (like a keyless entry) but they can reach much higher distances. Because I often leave my AirTag in the house and it gets detected very often despite me not even having an iPhone :)
