Solution to the Problem of Simultaneous On-the-air Activation Devices Class A/C LoRaWAN

This paper discusses the problem that appeared as a result of the project on remote control of devices in LoRaWAN networks, and the method of its solution. The paper shows that several LoRaWAN devices (four devices) located next to each other interfere with the simultaneous connection to the network. The problem is that four adjacent Vega SI-12 devices cannot reconnect to LoRaWAN server from class A to class C when power is simultaneously applied to these devices. This paper discusses several ways to solve this problem. The described methods partially solve the problem by increasing the number of reconnected devices, but do not solve the problem completely. One method has been developed that allows located next to each other multiple devices to reconnect to LoRaWAN with 100 percent probability and implemented on electronic solutions available to ordinary users. This paper will help system integrators of IoT technology to solve problems of simultaneous rejoin Vega SI-12 devices from Class A to Class C.
