# Li-Fi achieves 224-Gbps data transmission speeds with room-scale coverage

- The Oxford University researchers published their research work in the IEEE Photonics Technology Letters journal and described an indoor optical bidirectional wireless link with an aggregate capacity over 100 Gb/s.
- The researchers believe it is the first demonstration of a wireless link of this type with a FOV that offers practical room-scale coverage. The researchers achieved the performance by developing specialized broadcast LEDs and receivers operating with different fields of view and bands that affect the data transmission speeds.
- Li-Fi is only able to work within line of sight which means a computer would need to be in a fixed position for now. The speed is also dependent on the receiver's field of view. It can be described as working in a similar way to projectors and the research team are working to incorporate tracking technology into the system so that the light can locate the computer wherever it is placed in a room.
