LoRaWAN is a Long Range Wireless Radio Network protocol which is based on the LoRa physical layer protocol. It’s specially tuned for very long transmissions (more than 10km in rural areas) with low power consumption. LoRa is closed & proprietary protocol and no public documentation is available (though it has been thoroughly analysed see here). In contrast to the proprietary LoRa, the LoRaWAN specification is maintained by the LoRa Alliance and has been published.
LoRaWAN is the media access control protocol (OSI Layer 2) which uses LoRa (OSI Layer 1) the physical layer. It’s mainly used as a network layer protocol for managing the communication between the LoRaWAN gateways and end-nodes devices such as sensors and other IoT devices. In very basic terms, consider LoRaWAN the WiFi for IoT devices across every industry with a focus on low power and long range. LoRaWAN is primarily targeted towards IoT and Smart City applications. It has the potential to drastically improve the existing infrastructure, enhance the cities’ services and reduce cost. This project focus on the creation of the necessary infrastructure to establish the network as well as the services on top of it.
Following a non-inclusive list of a few applications for LoRaWAN which were deployed with customers selected for pilot runs of the new LoRaWAN Network
- Smart Water Meters to improve leakage detection, prevent lost revenue due to inefficiency and boost productivity by reducing the required time to analyse the data
- Save energy and improve the sustainability of old building in the cities by optimising the energy management in a building
- Prevent flooding or drought in parks by continuously monitoring humidity levels
IWB as a government-owned utility and telecommunications provider in Basel-Stadt aims to build a neutral LoRaWAN Network and provide a platform to built applications upon. In contrast to typical service providers where the LoRaWAN infrastructure enables the sales of applications and service packages with high margins, the objective here is to provide a network infrastructure with strong signal coverage in the city of Basel-Stadt with reach into every house and basement. The purpose of the network is to provide a neutral platform on which applications can be built on.
