A discussion on the technical alternatives to internet shutdowns

Understanding how to leverage alternative communication networks

LoRaWAN Demystified and its applications beyong IoT

Submitted by Akshai M (@akshaim) on Jan 9, 2020

Status: Confirmed & scheduled

Abstract

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.

Outline

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 ?

Requirements

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
