Abstract: When it comes to creating projects based on the use of the Internet of Things (IoT), wireless sensor networks are often used. The use of edge computing in IoT technology allows reducing system response delays to sensor output signals and increasing the network throughput. At the same time, a short-range sensor network can work locally without access to the Internet, while long-range networks, as a rule, require access to the Internet and use both edge and cloud computing. The article analyzes the possible options for wireless data transmission during the implementation of both short- and long-range IoT projects. Specific examples show the possibility of data transmission over a short distance using ESP-NOW technology, nRF24L01 radio modules and the creation of a local Wi-Fi access point. The range of sensor data transmission between microcontrollers is practically determined for each proposed option. The calculation of the range of the LoRa radio line is carried out for the real sensitivity values of the RFM95W receiver. The use of the Okamura-Hata radio wave propagation model is proposed in order to estimate the total signal loss in the LoRa radio line. The essence of edge computing with the combined use of digital and analog sensors is shown.
