WiFi relies on invisible radio wave transmission, equipment power is increasing, and local electromagnetic radiation is bound to increase; The wireless signal passes through the wall and the network information is unsafe  These security risks are swept away in lifi  The spectrum is 10000 times larger than the radio spectrum, which means greater bandwidth and higher speed  The network setting hardly needs any new infrastructure  Lifi technology itself has its limitations  If the light is blocked, The network signal will be cut off  At present, a series of key technical products are hands-on by researchers
Lifi completes network setup without any infrastructure
 There is no commercial chipset
