WHY ONLY 4TH GENERATION ,NOT OTHERS GENERATIONS???

Our ultimate goal is to communicate with any type of information with anyone, at anytime, from anywhere. This is possible with the aid of WIRELESS TECHNOLOGY

Types of wireless CommunicationCellular Networks Wireless local area network

Introduction to wireless communication

GRAPHICAL REPRESENTATION OF GENERATIONS

4G technologies are sometimes referred to by the acronym "MAGIC,“

M- Mobile multimedia A-Anytime/any-where G-Global mobility support I-Integrated wireless and C-Customized personal service

4G wireless system

Localized/Personalized Information Organizational services Communications services and applications Entertainment services Mobile commerce (M-Commerce )

General 4G Services and 4G Applications

Support interactive multimedia User friendliness High speed, high capacity and low cost per

bit Higher band widths

Features of 4G Wireless Systems

Why Only TCP Not IP On WIRELESS??

Transmission Control Protocol(TCP)

Split TCP Connection Link Level Solution End-To-End Solution

POSSIBLILTY TO ENHANCING TCP IN 4G

Splitting TCP connections into two parts

M-TCP underlying architecture

To improve standard TCP to operate over 4G with more efficiency and reliability.

TCP perform very badly over wireless links and delayed packets.

TCP provides a very good service and reliability. 4G systems supports many applications like voice and video

transfer.
