Long Range Wide Area Network
Overview:
LoRaWAN stands for Long Range Wide Area Network. It's a standard for wireless communication that
allows IoT devices to communicate over large distance with minimal battery usage.
LoRa Server is an open-source LoRaWAN network-server, part of the LoRa Server project. It is responsible for handling (and de-duplication) of
uplink data received by the gateway(s) and the scheduling of downlink data transmissions.
LoRaWAN is a media access control (MAC) protocol for wide area networks. It is designed to allow low-powered devices to communicate with Internet-connected applications over long range wireless connections.
LoRaWAN can be mapped to the second and third layer of the OSI model.
How LoRaWAN Works?
At the most fundamental level, radio protocols like LoRaWAN are
fairly simple. The way star networks converse is similar to a
professor and students in a lecture. The gateway (the professor)
speaks to end nodes (the class), and vice versa.
This is an asymmetric relationship in terms of communication.
Everyone in the class could be trying to communicate with the professor
at the same time, but the professor would not be able to hear or
understand them all at once. Albeit extremely oversimplified, many
elements of
star topologies go back to this analogy.
