This website is part of the DIDI-project. DIDI is an abbreviation which roughly translates to "Internet of Things Initiative of the province of Drenthe".
It provides Internet-of-Things connectivity, without any charge, through LoraWAN-technology for all citizens and companies living and working in the province of Drenthe in the Netherlands (https://en.wikipedia.org/wiki/Drenthe).
LoraWAN is a communication technology which makes it possible to send small packets of data over long distances in a very power-efficiënt way. This makes it ideal to connect all kinds of devices (who don't need a streaming internetconnection but only send small amounts of data) who can function on a battery for 5-10 years.
To give you an idea of applications:
LoraWAN is very good for Smart City-applications like waste management sensors, streetlighting applications, smart parking applications. But is also very good for: the development of new businessmodels by companies who would like to charge customers for the use of their products (or services) instead of selling them (as they need a way of communication from the device to the company about when and how long the product was used).
The DIDI-network provides connectivity for all to The Things Network (https://www.thethingsnetwork.org/) and gives Non Profit Organisations, Startups and Innovating Businesses (within certain rules) the opportunity to develop their products on the DIDI-backend-server.
