Internet of Things (IoT)

The IoT is the networking of objects over the internet, such as, for example, industrial machines, cars, TVs and washing machines. Billions of “intelligent objects” are being created as a result of this networking and the ever-increasing proliferation of sensors in (everyday) objects. However, a standard definition of the IoT has not yet been adopted by the various participants involved.

IoT network technologies

IoT objects / devices such as automated vehicles, networked traffic lights, parking sensors, smart TVs or intelligent washing machines use different network/transmission technologies. The transmission technologies are split into the categories of “Wide Area IoT” and “Short Range IoT”.

Radio frequencies / spectrum

Most IoT objects are connected to the internet over a wireless network, e.g. LoRa, Wi-Fi or 5G, and require spectrum/frequency resources as well as protection from interference. OFCOM is responsible for the management of these resources in Switzerland and accordingly ensures that sufficient frequencies or spectrum can be found for the various applications.


The development of the IoT is forging ahead throughout the world. In order to be able to evaluate regulatory requirements promptly, OFCOM is monitoring developments in the international environment and various standardization bodies. Developments, for example concerning built-in SIM cards, requirements in terms of spectrum resources and dealing with proprietary IoT solutions, are carefully monitored.
