AWS IoT Core for LoRaWAN replaces a private LoRaWAN network server (LNS) by connecting your LoRaWAN devices and gateways to AWS. Using the AWS IoT rules engine, you can route messages received from LoRaWAN devices, where they can be formatted and sent to other AWS IoT services. To secure device communications with AWS IoT, AWS IoT Core for LoRaWAN uses X.509 certificates.
AWS IoT Core for LoRaWAN manages the service and device policies that AWS IoT Core requires to communicate with the LoRaWAN gateways and devices. AWS IoT Core for LoRaWAN also manages the destinations that describe the AWS IoT rules that send device data to other services.
The following topics will provide more information about the LoRaWAN technology and AWS IoT Core for LoRaWAN.
What is LoRaWAN?The LoRa Alliance describes LoRaWAN as, "a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated âthingsâ 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.".
LoRa and LoRaWANThe LoRaWAN protocol is a Low Power Wide Area Networking (LPWAN) communication protocol that functions on LoRa.
LoRaWAN has been recognized as an international standard for low power wide area networking. For more information, see LoRAWAN formally recognized as ITU internationl standard. 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. LoRa is a physical layer protocol that uses spread spectrum modulation and supports long-range communication at the cost of a narrow bandwidth. It uses a narrow band waveform with a central frequency to send data, which makes it robust to interference.
Characteristics of LoRaWAN technologyLong range communication up to 10 miles in line of sight.
Long battery duration of up to 10 years. For enhanced battery life, you can operate your devices in class A or class B mode, which requires increased downlink latency.
Low cost for devices and maintenance.
License-free radio spectrum but region-specific regulations apply.
Low power but has a limited payload size of 51 bytes to 241 bytes depending on the data rate. The data rate can be 0,3 Kbit/s â 27 Kbit/s data rate with a 222 maximal payload size.
LoRa Alliance specifies the LoRaWAN protocol using LoRaWAN specification documents. To account for the region-specific regulations, the LoRa Alliance also publishes regional parameter documents. For more information, see LoRaWAN regional parameters and specifications.
The initial release of LoRaWAN is version 1.0. Additional versions released are 1.0.1, 1.0.2, 1.0.3, 1.0.4, and 1.1. Versions 1.0.1-1.0.4 are commonly referred to as 1.0.x.
