The “LiFi by LumEfficient” solution enables the deployment of a full wireless network through a bidirectional line rate up to 42 Mbps. The LumEfficient LiFi system offers high-speed mobile connectivity within a network while supporting multiple access points and handovers. Each LiFi luminaire can simultaneously serve up to 8 LiFi USB keys. The implemented handover functionality allows users to keep automatically a stable connection from one luminaire to another. The LumEfficient LiFi luminaire is compatible POE / POE+ and UPOE to minimize the necessary wiring for the deployment of a LiFi network infrastructure.
