In this video, we take a look at the Lilygo t-beam 1.1 and show how the Meshtastic systems are so great for civilian use, even over higher-end military hardware.

DIY Solar Meshtastic Unit:

The meshtastic system is a great new communication software that uses an app to give the user off-grid SMS communication in a variety of situations. The product we showed in our video, the Lilygo t-beam meshtastic 1.1 is also relatively cheap which allows you to build a simple and easy SMS network.

Unlike conventional ham radio setups, the meshtastic network is comprised of nodes that share information with one another. This means the network grows in size with each node added and reinforce the overall communication of the entire system. With this design, it’s much more difficult to shut down the communications network by taking out a single node. Combined with the relatively inexpensive cost, losing a node doesn’t have a significant cost impact either.

One other large advantage is that the meshtastic system operates on 915 MHz. There are so many common devices on this channel that the entire spectrum is just bombarded with signal noise from other innocuous items such as water meters, televisions, and smart devices. This means finding a node using foxhunting can be extremely difficult, if not impossible.

This then allows the user to build a cheap, robust, and difficult to circumvent comm network that can be placed in large or small areas. Each T-beam can also be loaded into a waterproof container and connected to a solar charging system for outdoor nodes that can be placed discreetly.

While the Lilygo meshtastic 1.1 system may not be the end all communication option, it shows us the new edge of comm technology and gives me a lot of hope of where this product will take current technology. Being able to speak, have that message be converted to text, then spoken back to the member is something I’m sure we’ll see in future iterations.
