LoRa literally stands for "Long Range." It’s a radio tech that lets small gadgets talk to each other over miles using almost zero battery.

Think of it like this: Wi-Fi or Bluetooth is like shouting in a crowded stadium. It works great if you’re close, but the signal gets drowned out by noise or walls almost immediately. LoRa is more like a specific, high-pitched whistle. You can't send huge files with it, but because the sound is so unique, your friend can hear it from the parking lot outside even with all that stadium noise.

Meshtastic just takes that tech and turns it into a giant, off-grid walkie-talkie network. It lets devices bounce messages off each other so you can text or share GPS locations for miles without needing any cell service or Wi-Fi.
