LED is in the spotlight as next generation's lighting due to the fact that it has good efficiency on converting electricity to light and has long life time. Recently it expands the scope up to taillight of car, signal lamp and indoor light. Additionally it can send data information simultaneously with lighting, which is called lighting-communication convergence. In this paper, the channel characteristics of LED wireless communication is studied in the condition that indoor is latticed with 1mm span and photons started from LED are firstly arrived at each lattice after that these move as straight line before meeting photodiode(PD).
