6. LoRaWAN
TM
Deployment
S76S/S78S contains STM32 & SX1276 HW environment for RF
transmission by LoRA modulation, providing physical layer for creating long
range communication link, and S76S/S78S also has capability to construct
LoRaWAN
TM
protocol for improving battery of life, better security and
effective management.
User can utilize AcSiP S76S/S78S SDK MCU & SX1276 ready LoRa®
drivers, to develop & customize their own commands and LoRaWAN
TM
protocol by different regional radiation rules.
6.1 What’s LoRaWAN
TM
LoRaWAN™ defines the communication protocol and system
architecture for the network while the LoRa® physical layer enables the
long-range communication link. The protocol and network architecture
have the most influence in determining the battery lifetime of a node, the
network capacity, the quality of service, the security, and the variety of
applications served by the network.
The detailed introduction & related resource of LoRaWAN
TM
can be found

. Please
read them first for reviewing some basic LoRa® & LoRaWAN™ foundation.
6.2 LoRaWAN™ Open Source
For reducing LoRaWAN™protocol (stack) deployment time, there’re
some existing open source resource that can be referenced and
constructed on S76S LoRa®driver. By the basic requirement, the open
source LoRaWAN™ stack needs to provide EU868 or US915 bands on Class
A and Class C endpoint implementation which is compatible with
LoRaWAN™ 1.0.1 specification at least.
By AcSiP’s local testing, the open source code, LoRaMac-node, can pass
EU868 LoRa-Alliance compliance test. Therefore, combined with AcSiP open
source LoRa drivers, user can develop their specialized LoRaWAN™ protocol
on S76S/S78S which is compatible the above requirement.
