đĄ Stay Connected AnywhereâNo Cell Service Required
If youâve ever found yourself frustrated by the lack of cell coverage or internet access during an emergencyâor while hiking in remote areasâthis compact $100 mesh radio could be a game-changer. It lets you send and receive SMS text messages with others up to 100 kilometers away, all without relying on cellular networks, Wi-Fi, satellites, or even a license. And best of all? Itâs completely free to use and open source based.
đ How It Works
Mesh radios extend their range by relaying your message from one device to another in a series of automatic âhops.â Each unit typically covers about 5 km, so as long as there are enough users nearby, your message can travel vast distances across the network.
đŹ Flexible Messaging Options
Broadcast Mode: Send messages to everyone within rangeâsimilar to a walkie-talkie or CB radio.
Private Mode: Use encrypted channels to communicate securely with family and friends.
Internet Bridging: If someone in the mesh has internet access, your message can be routed onlineâpotentially reaching recipients across the country.
Various MeshTastic devices
A variety of devices can be used with the service. I got the one with the long antenna for longer range on eBay for US$75.
