TCP Performance over 4G Wireless Networks
A TECHNICAL SEMINAR

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.
