From Li-Fi has a number of advantages. For example, the network can operate in conditions where the use of Wi-Fi could interfere with the proper operation of the equipment. As for data transmission Li-Fi uses light from the diodes, the technology can be successfully used under water.

However, despite all the prospects, the difficulties with the widespread introduction of Li-Fi could also be because it has drawbacks. For example, through the wall network signal is not transmitted, this means that to transmit the information necessary line of sight that already complicates equipment Li-Fi-network of a large building, which houses many separate rooms.
