› Increase in communication data transmission ongoing
› 5G rollout ongoing. Beyond 5G & 6G upcoming
› Radio spectrum occupied, solutions are looked for
› Societal impact telecom more important
› Europe Digital Strategy

Study OWC:
2 basic options, both possible
› LiFi Visual Light Communication
› Beamsteered IR Light communication BS-IRL
› (plus: FSO in space: Optical Wireless Satellite Network)
Conclusions
› OWC maturing and may help relieve spectrum scarcity
› LiFi and BS-IRL
– potential for indoor short range digital connectivity.
– might become complementary and/or alternative to RF e.g. Wifi.

OWC regulations
* Only when OWC device includes RF module, e.g. for on/off , location, or any other reason
E.g.
› Spectrum > 3000 GHz (i.e. expected to be non-regulated, and/or license exempt)
› Radio Equipment Directive* 2014/53/EU: Essential requirements
• EMF (protection health, ICNIRP)
• Electromagnetic Compatibility (EMC)
• Efficient use of frequencies, avoid harmful interference
• ….
› EMC Directive 2014/30/EU
› General Product Safety Directive 2001/95/EC andNEN-EN-IEC 62031
› Eye safety (e.g. IEC 60825-12:2019, IEC 62471, Recommendation ITU-T G.996 Amd. 1,)
› Low Voltage Directive (LVD) 2014/35/EU
› ..

Triple Helix model
NL positively engaged in development OWC
› Triple Helix model of cooperation (Universities + Companies + Government)
› NL has a wide ecosystem and culture on fieldlabs
› Sandbox, test licenses on spectrum
› Photonics & Light Technology: National key technology (HTSM)
› Government invested in photonics (e.g. in Photondelta , Smart Photonics, the Free consortium)
› Agentschap Telecom: international workshop (2017), study on OWC (2018),
› ITU R-report (2018) , started ITU-R Recommendation (in conj. with ITU-T and IEEE) (2019)
› Member EU NEWFOCUS / network on future generation optical wireless communication technologies (2020)

Conclusive reflections on OWC
11
› To benefit from the full potential of OWC a high-speed access network is required
› In-building fixed (wired) backhaul: an essential link in an OWC solution.
› OWC relatively safe, but there are some points of attention.
› Focus on (further) interoperability and compatibility among industrial products within OWC community, and also compatibility with already deployed communication technologies.
› Whether and when OWC will be successful also depends on economies of scale.
Public interest
› Safety & Health
› Non-disturbance, non-interference
› (Cyber)security
› Energy
› Interoperability & standardization.

“ We can’t innovate frequencies. But we can innovate the way we use them !”
Thank you for your attention
