!!! Overview
[{$pagename}] (from "long range") is a [Proprietary Network Protocol|Proprietary Protocol]  [Low-Power Wide Area Network].


[{$pagename}] is based on spread-spectrum modulation techniques derived from  [chirp spread spectrum|https://en.wikipedia.org/wiki/Chirp_spread_spectrum]  (CSS) technology.%%sup [[2]/% It was developed by Cycleo of  [Grenoble, France|https://en.wikipedia.org/wiki/Grenoble] and acquired by [Semtech|https://en.wikipedia.org/wiki/Semtech], the founding member of the LoRa Alliance; it is patented.


[{$pagename}] uses license-free sub-gigahertz  [Wireless] bands:
* EU433 (433.05-434.79 MHz) and EU863-870 ( [863–870/873 MHz|https://en.wikipedia.org/wiki/Short-range_device#SRD860] ) in  [Europe] 
* AU915-928/AS923-1 (915–928 MHz) in  [Australia]
* US902-928 (902–928 MHz) in [North America]
* IN865-867 (865–867 MHz) in  [India]
* AU915-928/AS923-1 and EU433  [Southeast Asia]
* 2.4GHz worldwide.


[{$pagename}] defines the lower [Physical Layer], the upper [Network Layers] were lacking. [LoRaWAN] is one of several [protocols] that have been developed to define the upper layers of the network. LoRaWAN is a cloud-based  [Media Access Control]  ([MAC]) layer protocol, but acts mainly as a [Network Layer] protocol for managing communication between [LPWAN] [Gateways]  and [Node] [Devices] as a routing protocol, maintained by the [LoRa Alliance|https://lora-alliance.org/|target='_blank'].
