Long-range Wireless Network for IoT Enabling Two-way Communication to Provide Coverage in Remote Locations

This paper deals with wireless networks, especially in the Internet of Things area. The aim is to design and implement a custom system for IoT in terms of hardware and software, using a suitable wireless transmission technology with the possibility of working in a mesh network topology, whose main advantages are the long communication range and low energy consumption. In order to develop the system that meets the specified requirements, universal, autonomously working, communication units are created. The user interface of the system allows to observe the status and evolution of the measured quantities, as well as to enter requests to the end stations. By deploying the system, it is possible to operate coverage-independent long-range bidirectional wireless communication. To ensure reliable data delivery, a packet delivery confirmation solution has been developed and backup technology is also included. The system is tested by deploying it on several sample tasks demonstrating its possible real use.
