ESP32-based LoRa / LoRaWAN wireless network

One way of long-range and low-power data transmission is LoRa wireless technology. Since the Internet of Things market (with ESP32 – based solutions) is mainly covered with short-range Wi-Fi and Bluetooth and long-range with 3G / NarrowBand-IoT technologies, LoRa oftens is omitted or simply unknown by IoT users. Below you will find a short representation of what LoRa is and how can it be used.

What is LoRa / LoRAWAN network?

LoRaWAN® network architecture is deployed in a star-of-stars topology in which gateways relay messages between end-devices and a central network server. The gateways are connected to the network server via standard IP connections and act as a transparent bridge, simply converting RF packets to IP packets and vice versa. The wireless communication takes advantage of the Long Range characteristics of the LoRa physical layer, allowing a single-hop link between the end-device and one or many gateways. All modes are capable of bi-directional communication, and there is support for multicast addressing groups to make efficient use of spectrum during tasks such as Firmware Over-The-Air (FOTA) upgrades or other mass distribution messages.


Industrial use of LoRa & ESP32-based solutions

One of industrial IoT devices, supporting LoRa wireless technology is ESP32 based eModGATE from TECHBASE. Economical, ESP32-based solution can serve as an end-point in any installation or works well as a gateway, gathering data from scattered sensor mesh across the installation. For more information and also Raspberry Pi based solutions check Industrial IoT Shop with all the configuration options for eModGATE.
