Light is simply a source of energy that has almost no adverse consequences so there is no contamination or damage.
The suddenly flickering light is a major blessing[A.Wilkins.2010], Data can be coded by changing the rate at which the LEDs are flicking on and off.
Aircraft and hospitals [Wilkins.2010], utilizes light rather than radio waves that are essentially secure and do not produce Electromagnetic Induction (EMI).
Visible light does not penetrate walls or other open materials and [Pathak.2015] can be guided into the desired working region, LiFi can show a high level of spatial reuse.

The usage of various uplink and downlink systems results in HetNets present many functional problems [Pathak.2015], including dynamic network management and efficient data recovery

Many natural and artificial light sources interact and act at the receiver as unpopulated source. This disturbance raises shot noise 2 [D. Karunatilaka.20015] and saturation will occur if high enough. And hence the quality of the network decreases.
