Interference-free Lifi networks

Interference-free Lifi networks
Technology News |
LiFi, or visible-light communication, has significant advantages over WiFi, such as data-transmission speed and the data security it offers because light does not penetrate walls. But wide adoption is constrained primarily because of interference between devices using LiFi networks and LiFi’s resulting poor performance in large areas.

To solve this issue, researchers at CEA-Leti have designed a LiFi-multicell system which they believe is the first-ever smart interference orchestrator that automatically detects interference between lighting zones in networks and optimizes data transmission rates for each nearby device. The system also manages, asymmetrically and independently, uplink/downlink interference.

The LiFi-multicell to be demonstrated at CES 2020, CEA-Leti offers several advantages in addition to eliminating interference and supporting large-area coverage. These include uninterrupted connectivity for users moving in a network and fair allocation of resources between users who are experiencing interference and those who are not. The CEA-Leti technology is able to provide data-transmission rates up to 150 Mb/s over distances up to three meters by LED.
