LoRa and LoRaWAN
|

################

|
Overview
|
|
********
|
|
|
|
LoRa (abbrev. for Long Range) is a proprietary low-power wireless
|
|
communication protocol developed by the `Semtech Corporation`_.
|
|
|
|
LoRa acts as the physical layer (PHY) based on the chirp spread spectrum
|
|
(CSS) modulation technique.
|
|
|
|
LoRaWAN (for Long Range Wide Area Network) defines a networking layer
|
|
on top of the LoRa PHY.
|
|
|
|
Zephyr provides APIs for LoRa to send raw data packets directly over the
|
|
wireless interface as well as APIs for LoRaWAN to connect the end device
|
|
to the internet through a gateway.
|
|
|
|
The Zephyr implementation is based on Semtech's `LoRaMac-node library`_, which
|
|
is included as a Zephyr module.
|
|
|
|
The LoRaWAN specification is published by the `LoRa Alliance`_.
