LoRaWAN
The LoRaWAN® specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.
What is a LoRaWAN?
The LoRaWAN protocol is a Low Power Wide Area Networking (LPWAN) communication protocol that functions on LoRa. The LoRaWAN specification is open so anyone can set up and operate a LoRa network. LoRa is a wireless audio frequency technology that operates in a license-free radio frequency spectrum.
Is LoRaWAN free?
LoRaWAN® specification is an open standard, it is open to anyone, free of charge, and there are no license fees or other fees associated with its usage. There are open-source implementations of the LoRaWAN® stack, both on the device side, and the cloud side. In that sense, LoRaWAN® is free to use.
How far can LoRa transmit?
The name, LoRa, is a reference to the extremely long-range data links that this technology enables. Created by Semtech to standardize LPWANs, LoRa provides for long-range communications: up to three miles (five kilometers) in urban areas, and up to 10 miles (15 kilometers) or more in rural areas (line of sight).
What devices use LoRaWAN?
For over two years, the city of Tainan has used LoRaWAN devices to monitor garbage trucks and also monitor the water levels of rivers. Other cities across Taiwan deploy LoRaWAN in many different use cases: to manage dams, deliver fresh food, and even monitor bikes on the road.
Can LoRa transmit audio?
Can LoRa transmit audio?
A LoRa FM Radio Transmission station is a great way to have a cheap affordable always on play the sound over the air. you can speak into a microphone and broadcast your voice or pick audio files over this device and play them.
Can LoRa go through walls?
Researchers from the University of Massachusetts, University of Colorado Boulder, Peking University, the Chinese Academy of Sciences, and the Institut Polytechnique de Paris have demonstrated how LoRa radio signals can be used for through-wall sensing at long ranges — in much the same way as Wi-Fi
