What is MeshCom? – a simple overview
MeshCom is an open source project from the Institute of Citizen Science for Space & Wireless Communication (ICSSW), which aims to realize text-based communication via LoRa modules in amateur radio (433 MHz).
- Messages, position data, telemetry and control functions can be sent via LoRa.
- MeshCom nodes automatically connect to form a network (self-building) and adapt flexibly in the event of failures (self-healing).
- Each node reports with its amateur radio call sign (possibly with SSID). Messages can be sent specifically to a recipient or as a broadcast.
- Gateways allow MeshCom to be connected to HAMNET, APRS, Telegram Bots and more.
- The firmware is based on AX.25 / APRS principles, adapted for LoRa.
- Existing hardware platforms include: B. ESP32/LoRa boards, WisBlock, T-Deck etc.
Advantages of MeshCom
Use in amateur radio context
Since MeshCom is based on amateur radio principles – with call sign, AX.25 / APRS – its use is clearly anchored in the non-commercial, experimental area.
Energy efficiency & cost-effective hardware
LoRa allows very economical power consumption, ideal for locations with limited energy supplies.
Robustness & reliability
Mesh networks with self-healing ensure that failures of individual nodes do not paralyze the entire network.
Expandability & network connection
MeshCom can be connected to HAMNET or the Internet through gateways – spatially separate networks can be linked.
Operation when classic infrastructure fails
In crisis situations or network failures, MeshCom can be operated independently and serve as a backup.
The “Getting Started” video by Jürgen (OE4JHW)
Embedded below you will find the video by Jürgen OE4JHW, in which he shows step by step how to set up and operate a MeshCom node: https://www.youtube.com/embed/xruVBAMmabM
Many thanks to **Jürgen OE4JHW** for this clear video – a valuable introduction for all newcomers!
My use: own nodes & plans
In this section I describe my practical experiences:
- I flashed two MeshCom nodes and put them into operation. (see photos below)
- Node 1: Will soon be mounted under the roof and equipped with a better antenna to increase range and stability.
- Node 2: Used mobile for /P (portable use) – to test temporary connections on the go.
Let’s rock the mesh – start your own network!
With little effort – an ESP32/LoRa module (433MHz), some tinkering time and curiosity – you can build your own MeshCom node and become part of a decentralized communication network. Once you mount your node under the roof and provide it with a good antenna, or join /P on the go, not only does the network grow – the fun factor increases with every new connection hop. So what are you waiting for? Start your first node, bring it online – every new participant strengthens the mesh! And: Stay tuned – networks like Meshtastic and MeshCore will soon be coming to enable applications outside of amateur radio with similar hardware and other frequencies.
JOIN IN: There is still a lot of untapped potential for new MeshCom nodes, especially in OE8. Take the opportunity to build your own node and expand the network in your region!
