3. 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.
It was formed in June 2001 to promote conformance and
interoperability of the IEEE 802.16 standard officially known
as Wireless MAN.
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.
WiMAX service providers covering 430 million people
globally in 135 countries today.
4G at a 3G price
Speeds of up to 100 Mbps
