The CES 2022 event was enlivened by the presence of the first Android tablet carrying a LiFi (Light Fidelity) connection. The tablet is named LiFiMAXTab by Oledcomm.
This tablet completes the range of Access Points, Photonic Antennas and USB dongle. Bringing LiFi capabilities to the home is right to be used as a combat tool for those who work from home (WFH).
"This tablet allows all family members to connect to the Internet through invisible light, providing a strong, stable radio frequency-free connection, with a signal that cannot be intercepted from outdoors. LifiMAXTab is ideal for use in the office, for the elderly and children alike. child at home or at school," said Benjamin Azoulay, President of Oledcomm.
LifiMAXTab has an integrated LiFi module with 150Mbps downstream and 150Mbps upstream speeds. In addition, Oledcomm has a 3Gbps point-to-point connection at a distance of 1 to 5m.
This tablet features a 10.1-inch screen with a resolution of 1920 x 1200 pixels. Oledcomm capitalizes it with the MediaTek MTK6762 chipset combined with 4 GB of RAM and 64 GB of internal memory.
There are two cameras installed on this tablet, each measuring 2 MP and 5 MP. LifiMAXTab has USB Type C, 3.5 mm audio jack, TF card reader and 8,000 mAh battery.

Oledcomm will sell LiFiMaxTab in February 2022. The price is 400 euros.
To note LiFi is a wireless optical network 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 communications such as Wi-Fi and complies with the IEEE IEEE 802.15.7 standard. IEEE 802.15.7 is a standard based on a high-speed, bidirectional, full-network wireless communication technology similar to IEEE 802.11 Wi-Fi.

Talk about how it works LiFi consists of several light bulbs that form a wireless network. When an electric current flows into an LED bulb, streams of light (photons) are emitted from the lamp.
Signals are sent by modulating light at different rates. The signal can then be received by a detector which interprets the change in light intensity (signal) as data.
The main benefits of LiFi are as follows:
• Security : Provides completely secure access. Where there is no light, there is no data.
• Security : Does not produce electromagnetic radiation and does not interfere with existing electronic systems.
• Localization : Enables localization due to the small coverage area of LiFi access points - localization can be used for very precise asset tracking.
• Data density : Provides ubiquitous high-speed wireless access that offers significantly greater data density (data rate per unit area) than RF through high bandwidth reuse.
