Latest Linux Kernel Upgrade Release 5.19 Includes pureLiFi’s LiFi Drivers
pureLiFi released an article today stating that the recent Kernel release 5.19 broadly acknowledged as a sizable upgrade incorporates security and network improvements that include LiFi drivers to support pureLiFi systems. The official Linux Kernel is the basis for all Linux distributions ranging from Ubuntu and Fedora for PCs and servers, to Android for mobile devices.
Alistair Banham pureLiFi CEO stated the following:
“This marks the first time a major operating system has included a LiFi driver in an upgrade. This is another great endorsement for LiFi and signals a growing maturity and interest in LiFi for broader use. The inclusion of LiFi drivers in the latest Linux upgrade will allow users to plug and play our LiFi system.”
Edinburgh-based pureLiFi uses light to transmit data unlike conventional radio frequency systems such as WiFi and 5G. By harnessing the light spectrum LiFi is able to provide more reliable wireless communications with unparalleled security.
LiFi is complementary and additive to the existing WiFi technology, offering more reliable connections, with lower latency and 2,600x greater network capacity. Additionally, when the WiFi and LiFi work together the users across both technologies experience greatly improved connectivity, as LiFi also makes WiFi better by freeing up capacity and reducing interference on the WiFi network.
pureLiFi announced in 2021 the first-ever large-scale deployment of LiFi with the US ARMY and most recently announced a £10M investment from the Scottish National Investment Bank to expand the technology globally.
Alistair Banham expands on this recent development:
“The addition of LiFi in the Linux kernel is just the beginning. We look forward to driving the adoption of LiFi and the inclusion of pureLiFi drivers in more operating systems. This is another important milestone in our journey to connecting everything and everyone with LiFi.”
pureLiFi
pureLiFi develops technology for communication networks that integrates data and lighting utility infrastructures. It offers a LiFi-enabled device that converts the beam of lights into an electrical signal. The signal is then converted back into data. The company was founded in 2012 and is headquartered in Edinburgh.
Technologies such as WiFi, 4G and 5G use radio frequencies to transmit data, which produce large areas of radio frequency emissions that are easy to detect, intercept, and can cause overcrowding resulting in slow speeds and unreliable communications due to increased RF congestion. LiFi uses light rather than radio frequencies resulting in wireless communications that are more reliable, significantly more secure, and simpler to deploy.
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.
