Ans: It is just-like a barbecue cooking technique, where you place the food to the side or above the heat source, rather than placing it directly over the flame. For this grilling process, you require a little more space to revolve food around splitting the grilling area. Thus, it has a separate place for charcoal and food and you can place food on the opposite side to hot coal. (or) you can place food in the center with coal on the sides.
