Introduction

Definition :

According to the Wireless World Research Forum (WWRF),4G is a combination of wired and wireless networks in computer, consumer electronics and communication technology systems based on the internet technology that can merge applications like the Wi-Fi and Wi-MAX capable of transmitting at a speed ranging from 100 Mbps(in cell-phone networks) to 1Gbps(in local Wi-Fi networks). It is also known as “beyond 3G,"

WiMAX is defined as "Worldwide Interoperability for Microwave Access" by the WiMAX Forum. WiMAX aims to provide wireless data over long distances, in a variety of different ways, from point to point links to full mobile cellular type access.
