Installation of Li-Fi GigaDock® of Fraunhofer Institute for Photonic Microsystems IPMS On The ISS Space Station
The Fraunhofer Institute for Photonic Microsystems (IPMS) released a press statement on its website on Monday 07th November. They have developed a LiFi transceiver that guarantees data transfer between the components. This was integrated into the iBOSS GmbH interface and has been on board the ISS (International Space Station) for testing purposes since February 2022.
In order to be able to flexibly attach and detach modules directly in space, easy-to-couple and standardized components are particularly important. In addition to the mechanical coupling of the individual modules, it is essentially a matter of ensuring the transfer of data and energy between the individual modules so that satellites can be combined as required. For this reason, RWTH Aachen University applied for a patent years ago, which has now been brought to market by the spin-off iBOSS GmbH as iSSI® (intelligent Space System Interface) and forms a standard interface for such systems.

Part of the interface is a development of Fraunhofer IPMS and also known as Li-Fi GigaDock®. The core of the technology is an optical wireless transceiver, a highly integrated device that enables contactless full-duplex and bidirectional data transmission with a data rate of up to 5 Gbps. The possible transmission distance of the optical data interface is five centimetres. The component can also be used for rotor-to-stator transmission, as the transceiver functions perfectly even at high speeds.
"Building on this component, Fraunhofer IPMS has developed a communication module for iBOSS that has now made it into space, or to be more precise, even onto the ISS," says a delighted Alexander Noack, head of development for optical wireless communication. "In addition to space travel, the component can be found in industrial communication systems, in medical technology as well as in docking applications," he continues.

In February, the interface flew into space for testing and demonstration purposes and was mounted by a robot for the first time on the Japanese part of the ISS. The module is to remain there until mid-December and prove its operational capability under vacuum conditions and the influence of radiation.
Interested parties can find out more about the technology at the Electronica trade fair in Munich from November 15 - 18, 2022. Fraunhofer IPMS will exhibit its LiFi developments in hall B4 (booth B4.258).

Li-Fi Conference 2022
The Li-Fi Conference 2022 Edition was a great success. Li Fi Tech News will very soon write articles on the topics treated at the Conference.
What is LiFi?
LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).
VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.
How does LiFi work?
LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several light bulbs that form a wireless network.
When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.
LiFi Benefits
The primary benefits of LiFi are as follows:
• Security: Provides entirely secure access. Where there is no light there is no data.
• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.
• Localisation: Allows localisation due to the small coverage area of LiFi access point - localisation can be used for very precise asset tracking.
• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.

LiFi Systems Reviews by LiFi Tech News
OLEDCOMM LIFIMAX KIT REVIEW - ONE YEAR IN
We reviewed the LiFiMax kit produced by the leading French LiFi company Oledcomm. We bought this LiFi kit system at the end of 2020. After over a year of use, we decided to write a review of this LiFi system. We looked briefly at the profile of Oledcomm, a brief history of the LiFiMax system, the Kit box contents, some testing and performance results of this LiFi system, the customer experience and our own verdict (the good and the bad points) of the LiFiMax kit.

SIGNIFY TRULIFI 6002.1 STARTER KIT SYSTEM REVIEW
We also reviewed the Trulifi 6002.1 starter kit produced by Signify, the world leader in lighting for professionals, consumers and lighting for the Internet of Things. We got this LiFi kit system with the help of PCDSI and Signify around August 2021. In a similar fashion done with our previous review of the LiFiMax kit a few months ago, we will look briefly at the profile of Signify, a brief history of the Trulifi 6002.1 kit, the Kit box contents, some testing and performance results of this LiFi system, the customer experience and our own verdict (the good points and the bad points) of the Trulifi 6002.1 kit.
