A set of radio devices and technologies is transforming the communication landscape, offering alternatives to traditional network structures. These innovations not only aim to improve connectivity but also facilitate more resilient forms of communication that are resistant to censorship and surveillance.
The so-called “mesh networks” are technologies that have gained popularity in router protocols and the Internet of Things. The novelty lies in the emergence of affordable devices that allow long-distance communication without the need for licenses, known as Long Range (LoRa). Despite variations in frequency by country, LoRa employs Chirp Spread Spectrum technology, enabling it to transmit data several kilometers under optimal conditions.
Although the transmission speed is low, generally below a few kilobits per second, LoRa’s energy efficiency is noteworthy. Its true utility becomes evident in situations where communication infrastructure is limited or intermittent, such as in Search and Rescue operations, where its combination with GPS sensors can be crucial.
The Meshtastic system has become popular among mesh communication enthusiasts. This system allows users to securely exchange messages between Meshtastic-enabled devices. Additionally, it can relay messages to other nodes, thus extending the range of communication through network collaboration.
On the other hand, Reticulum offers superior flexibility, functioning as a network stack that provides connectivity via TCP/IP, anonymous networks like I2P, and WiFi connections. Its LXMF transfer protocol enables the creation of various applications, from messaging to file transfers.
In a context marked by environmental disasters and political polarization, the stability of traditional networks is being challenged. However, new communication technologies are emerging as effective solutions for addressing unforeseen situations, empowering individuals and fostering resource sharing outside the control of centralized platforms.
Thus, an optimistic future is on the horizon, recalling the experimental spirit of the early days of the Internet. These technologies not only provide practical solutions but also pave the way for a more equitable and accessible technological environment.
