LPWAN – Low-Power Wide Area Network is a group of networks proposed for the Internet of Things applications, which require a low energy consumption and a long-range transmission. In 2013, an idea emerged and dedicated to the development of a global network covering up to several tens of kilometers in rural areas. The purpose of such
Connecting the radio module to the NodeMCU microcontroller via UART: D7 (NodeMCU) <—> Tx (YL-800N). D8 (NodeMCU) <—> Rx (YL-800N). From the received package, you can see the main data such as: Sender address The indicator of the level of the received signal. The size of the payload. Received useful information.
Based on the OMNET ++ and inet frameworks, LoRa network node model has been developed, which can be explored by various parameters LoRa. The LoRa node model is built from the physical layer to the application layer. Including, the LoRa network interface is the main component. The LoRa interface defines the physical layer — the
Using the CupCarbon simulator, networks based on WiFi IEEE 802.11, Zigbee IEEE 802.15.4, and LoRa can be modeled according to the specified parameters.
This module is a SX1276 chip based on the increased ESP32 WIFI OLED network, namely the LoRa remote modem, frequency 868 MHz, high sensitivity over 148 dBm, + 20 dBm output power, high reliability, long transmission distance. Built-in 32-megabyte Flash Wi-Fi antenna, 0.96-inch blue display, lithium battery charging circuit, CP2102 interface and USB serial chip,
