Understanding LoRa architecture: nodes, gateways, and servers

1 week ago | engineersgarage.com | Ayush Jain

To understand all about nodes, gateways, and servers, first, we must understand what a LoRaWAN or LoRa network is. LoRaWAN (long-range wide area network)LoRaWAN is a low-power, wide-area network (LPWAN) protocol designed to enable long-range communication between LoRa-based devices and the internet. LoRaWAN builds on the underlying LoRa technology, adding network and application layer features that make it a complete and standardized solution for deploying IoT devices and services.
How communication works between two LoRa end-node devices

Communication between two LoRa end-node devices can happen seamlessly. Both end-node devices include the LoRa E5 Mini Board, which switches quickly between sending and receiving messages — making two-way communication possible. In this setup, communication begins with one device sending a message and waiting for confirmation. Upon receipt, the receiving device sends a reply confirming the message was received.
How LoRa enables long-range communication

1 week ago | engineersgarage.com | Ayush Jain

LoRa (Long Range) is a type of wireless communication technology designed to send information over long distances with low power consumption. It uses a special technique called chirp spread spectrum (CSS) modulation, which operates by continuously changing the frequency of a transmitted signal over time. This varying frequency generates a waveform (resembling the sound of a bird chirping), allowing it to send signals over long distances without using a lot of power.
