The Telecommunications Department had invited you to the lecture evening with the theme:
"Smart Telecom in a new light"

The use of wireless networks has increased significantly in recent years. With a mobile device, such as a laptop, tablet or smartphone, information can be accessed via a wireless network from anywhere in the world. However, with the increasing use of internet-connected devices, the speed of data transmission is decreasing. This makes it increasingly difficult to use fast and secure wireless networks. Wireless networks offer many advantages but also have specific threats that can affect information reliability.

One solution to these problems is LiFi. Systems can modulate light waves to transmit data. In this, a USB light module is connected to a laptop or tablet and receives data at 150Mb/sec and sends data back to the transceiver in the luminaire at the same speed. By using lighting infrastructure, customers get the best of both worlds: top-quality light and a reliable, secure, high-speed wireless connection.

Prof Jean-Paul Linnartz (TU Eindhoven) expressed this internet's vision of lighting capabilities and explained his work as technical leader of the EU LiFi project ELIoT. In this, universities Oxford, TUe, Fraunhofer, Nokia, Signify, a chipmaker and telecom operators work together to get the innovations of Research institutes and academia into working products (and ICs).

Jeroen Thijsen (Nokia) went into Smart Lighting, internet with light concepts through lampposts. Nokia, through Smart Poles smart lighting poles, offers an all-in-one solution for cities and its residents - with a broadband connection, 4G/ 5G and WiFi infrastructure, as well as a platform for a number of IoT applications. And all while maintaining the aesthetics of the urban environment.

Finally, Ed Huibers (Signify, formerly Philips Lighting) explained how Signify is constantly modernising its Lifi portfolioand security to give the Dutch company a leading position on a global scale. It concluded with a real Lifi demonstration." see further the article "Surfing on Light! From WiFi to LiFi", in De Ingenieur 2, February 2020 (also available under the 'Documents' tab.
