LoRaWAN Demystified and its applications beyong IoT

Submitted Jan 9, 2020

The session ( more a discussion) will introduce the participants to LoRaWAN, Network and Security Architecture, its pros and cons and technical possbilities and challenges to transmit non real time data for those “needy” situations.


Tech : LoRaWAN is a star of stars network which makes use of LoRa Radio that works in ISM band and LoRaWAN MAC , an Open Source MAC by LoRa Alliance

Demo : The session will walk through making and transmitting an Encrypted LoRaWAN Payload to Network Server via a LoRaWAN Gateway . The payload is thendecrypted and exposed using an Application server and displayed using a dashboard.

Prospects : Route messages between LoRaWAN Edge Devices to establish a basic network using MQTT Service.

Problem Statements :

  • How to design an efficient packet forwarder in edge devices to transmit to devices ?
  • Packet routing between devices using MQTT service in App Server?
  • What should be the minimum data rate ?


Please see this tutorial [1] on LoRaWAN prior to attending the event. Please bring you laptops if you want to see the data for yourself
