### AI overview

A video by [nktbuilds] demonstrates a Bluetooth tracker tag communicating over a reported distance of 12 kilometers without extra transmit power. The setup uses a parabolic antenna to capture more signal and a sensitive receiver with a lower noise floor than typical phone hardware. The excerpt notes that this is a demonstration, not a reason to use Bluetooth for long-distance communications; it points to LoRa as better suited to that purpose, describing ranges from hundreds of miles with line of sight to tens of thousands with the right setup.

Bluetooth is a short-range protocol that's great for peripherals and finding your keys, but it's limited range is mainly a product of how it's usually implemented. A recent video from ...read more
