KEY FEATURES OF D2D COMMUNICATION

What are the important characteristic features of D2D communication? For D2D communication to be established, the following characteristics are to be considered. This article will provide you a complete picture of implementing Device to Device Communication MATLAB. Let us first start by understanding the characteristics of d2d communication.
