For the first time in the Netherlands, Signify's LiFi technology has been used to test a fully functional, secure, and interference-free optical connection between a ground station, a telescope, and an operational container. According to Signify, the successful test underscores that LiFi is an essential breakthrough for sectors where secure data transmission is crucial.
As part of the Wireless Optical Alliance, Signify recently conducted a groundbreaking test for this method of secure wireless communication. For the first time in the Netherlands, a fully functional optical alliance network was set up, in which a ground station, a telescope, and an operational container work together. This technology enables ultra-fast, “invisible” connections that are eavesdropping and interference-proof. This secure alternative to traditional radio and satellite connections is an essential breakthrough for the Ministry of Defense. Also, it opens the door to applications in autonomous vehicles, smart infrastructures, and sectors where secure data transmission is crucial.
Aircision
According to the initiators, what makes this test special is the successful integration of different types of wireless optical technologies. Aircision connected TNO's ground station and Signify's operational container, where the communication signal was received and processed via LiFi. “Signify's LiFi technology ensures 100% shielded, interference-free, and eavesdropping-proof data transmission – essential in situations where traditional radio connections fall short,” said Mark Gunther, Business Leader Trulifi Public, Defense & Transport at Signify. “We have been working closely with the Ministry of Defense for several years to deploy LiFi technology as a secure wireless communication medium. When radio is not an option and cables are unsafe, LiFi offers a reliable solution. We are proud to have brought this innovative technology closer to military deployment.”
Menno Smeelen of the Ministry of Defense points to the unique achievement that improves the Netherlands' independence. “What we have achieved together in such a short time is truly remarkable. Thanks to the commitment of all partners and the support of BITS, a close collaboration has developed from the outset. Everyone contributed their own strengths, and that is what made the difference. I am proud of the trust, energy, and results we have already achieved together.”
BITS (Brainport Innovation & Technology for Security) plays a key role in this consortium as a strategic partner, connecting high-tech companies with the Ministry of Defense. Together with the Ministry of Economic Affairs, the province of North Brabant, Brainport Development, and the Brabant Development Agency (BOM), BITS strengthens cooperation between the government and the business community, thereby contributing to the security and resilience of the Netherlands.
Vehicles, ships, and drones
The next phase is now in sight: establishing a direct connection between satellites and defense vehicles, naval vessels, and drones. Developing a largely Dutch technology and supply chain is central to this, so critical communication infrastructure remains entirely under Dutch control. Further tests and demonstrations will be carried out in the coming months, including within the Ministry of Defense, with attention from NATO, among others. This underlines wireless optical communication's international relevance and potential as a secure and scalable technology for both military and civilian applications.
Broad applications
Although this technology's initial focus is on defense, the possibilities are much broader. LiFi technology is versatile enough for applications in various civilian sectors, such as healthcare, mobility, and logistics, including self-driving vehicles. These development opportunities point to a future in which the Netherlands increases its security and sets independent communication standards.
