Now, LiFi-multicell, a system developed CEA-Leti, 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.
At CES 2020, CEA-Leti will demonstrate LiFi-multicell, which 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.
LiFi-multicell is the first-ever technology to enable massive rollout of LiFi, using a smart network orchestrator that can be hosted on any commercially available lightbulb. Typical applications include lighting manufacturers, Internet service providers, and smart-home stakeholders.
CEA-Leti researchers are working on additional smartmobility management features for LiFi-multicell. These will further increase data transmission speeds for users on the move and allow users to benefit from the best access point. The goal is to work with a manufacturer to develop a system that targets market demand.
