You'd also need a LoRaWAN network to hook into.
But most importantly, I doubt you could build a LoRaWAN tracker as compactly as an AirTag. A beacon would use significantly less electricity and therefore require a smaller battery.
Below is one of the smallest LoRaWAN modems on the market, which by itself is marginally bigger than an AirTag. Now add batteries, GPS, antennas, and an SoC to drive the whole thing.

- Scoundreller 5y agoThere are some groups building 'armageddon' mesh-based hand-held communicators like Meshtastic. Converged hardware is already there. The network probably is too in more and more metros if you're not within a few km of what you're trying to communicate with/track. https://meshtastic.org https://meshtastic.org Map: https://canvis.app/meshtastic-map https://canvis.app/meshtastic-map

- Friday_ 5y agoThis looks interesting, but device itself looks like it wouldn't survive fall on the floor, let alone armageddon. Just joking.
