1. What is LoRa?


LoRa: Long range, low power wireless platform is the prevailing technology choice for building IoT networks worldwide.


Smart IoT applications have improved the way we interact and are addressing some of the biggest challenges facing cities and communities: climate change, pollution control, early warning of natural disasters, and saving lives. Businesses are benefiting too, through improvements in operations and efficiencies as well as reduction in costs.


This wireless RF technology is being integrated into cars, street lights, manufacturing equipment, home appliances, wearable devices – anything, really. LoRa Technology is making our world a Smart Planet.

2. LoRaWAN Protocol


LoRaWAN is a protocol specification built on top of the LoRa technology developed by the LoRa Alliance. It uses unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) bands to enable low power, wide area communication between remote sensors and gateways connected to the network. This standards-based approach to building a LPWAN allows for quick set up of public or private IoT networks anywhere using hardware and software that is bi-directionally secure, interoperable and mobile, provides accurate localization, and works the way you expect. The specification is available for free to download from the LoRa Alliance website today.
