In the context of modern digital transformation, there is a steady trend towards expanding the range of services provided via wireless communication technologies. For example, the Internet of Things (IoT), which is capable of functioning and interacting with various communication standards, such as Wi-Fi, Bluetooth, Z-Wave, Zigbee. There are other highly specialized communication standards with their own characteristics, but they all have several disadvantages in common, which include a short signal propagation range (for most protocols no more than 100 m), high energy consumption, dependence on an Internet connection and the presence of cellular infrastructure. There is a need to create and deploy networks capable of providing critical information exchange in the absence of communication not only in everyday life, but also in conditions of high uncertainty. A promising direction for solving these problems is the development and implementation of Mesh networks. The aim of the article is to deploy an experimental Mesh network, combining ready-made commercial Mesh products and a self-developed radio device based on a Lora module using the open-source software "Meshtastic", to measure the signal transmission range. In this article, the authors successfully deployed Mesh networks at operating frequencies of 433 MHz and 868 MHz using commercial and proprietary. As part of the experiments, measurements of the text message transmission range were performed with the following configurations: direct radio communication between commercial devices, transit through the developed repeater. The development of autonomous mesh networks has not only significant scientific and practical interest in terms of organizing stable special-purpose telecommunication systems, but also practical value in various areas. This includes providing communications in remote and hard-to-reach regions with no telecommunications infrastructure, using them in commercial projects as a backup communication line, and using them in rescue operations.
