LoRa MESH NETWORKS
LONG RANGE (LoRa) MESH NETWORKS
LoRa mesh networks are a messaging and data radio technology employing modular LoRa (Long Range) development boards as “nodes” in a communication system which can operate independent of cellular phone systems or the internet. A great deal of interest is developing in this technology as it provides a communication option which would survive a loss of cell service or internet in an outage or emergency. The system leverages the ability of a node to send messages or data that is networked with other similar LoRa devices (thus the term “mesh”) whereby information is relayed from one device to another in a decentralized fashion seeking to deliver it to the intended recipient. Radio spectrum outside licensed bands is used.
The now popular “Meshtastic” project has emerged as a leading protocol providing an intuitive interface for utilizing this technology. Users can pair their node using Wi-Fi or Bluetooth with a single cell phone or similar device running Meshtastic enabling them to exchange messages and data over a distance through this peer-to-peer (p2p) rebroadcasting.
Areas without developed communication infrastructure (or areas experiencing a loss or outage of such infrastructure) can use this technology to achieve off-grid message and data exchange. Unlike a cellular network which is centralized and relies on a server, a mesh network as described here is decentralized allowing it to avoid outages or trouble due to the failure of a single point in a system.
Use cases are numerous, but notable ones are disaster relief, remote monitoring, outdoor recreation, hobby, and industrial automation.
Mesh Nodes Recently Installed in Lee County!
Meshtastic based LoRa nodes have recently been installed as follows:
- On top of the 911 center (Short Name W4LE, location 32.638093, -85.399112)
- Tower at the home of WB4BYQ (Short Name BYQ1, location 32.707346, -85.454556).
Mestastic users are encouraged to look for and utilize them.
