  In this era of modern devices and high speed communication the issue of
spectral overloading is increasing with time and becoming more serious. With
the advancement in LED industry, light fidelity (Li-Fi) based indoor network is
an attractive substitute for the existing radio frequency (RF) based
communication networks. Because of its capability to perform dual function of
lighting as well as high speed communication, Li-Fi is attracting both
industrial as well as academic researchers. The Li-Fi networking paradigm
offers performance enhancements which can make it an attractive backup option
to be used for networking setup in Internet of things (IOT) and its indoor
capabilities make it an attractive choice for large scale indoor communication
in next generation wireless networking environment. This paper discusses key
potentials of Li-Fi based indoor communication system and point out the
challenges which indoor based Li-Fi network is facing under the knowledge of
existing research work in the field of Li-Fi.
