\n- Both utilize LoRa radio technology to send text messages and GPS coordinates without cellular towers, Wi-Fi, or the internet.<\/li>\n\n\n\n
- Both create a “mesh,” meaning devices can bounce messages off each other to extend the network’s overall range.<\/li>\n\n\n\n
- Both can run on the same high-performance LoRa hardware.<\/li>\n<\/ul>\n\n\n\n
However, how they bounce those messages is where the two protocols diverge.<\/p>\n\n\n\n

In Meshtastic network, every device can act as a repeater.<\/strong><\/p>\n\n\n\nIt utilizes a routing protocol known as a “managed flood”. When your Meshtastic node sends a text, it essentially broadcasts the packet to every other node in range. Those receiving nodes then rebroadcast the signal to everyone they can reach until the message finds its target. This system is incredibly resilient\u2014if one node drops offline, it doesn’t matter, because others are already echoing your message. Everyone is an equal participant in keeping the network alive.<\/p>\n\n\n\n![\"\"](\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2026\/03\/meshtastic-1030x569.png\")
