Introduction to
Wirless
Technology
Our Ultimate goal is to
communicate with
any type of information
with anyone, at any time,
from any where
This is possible with
the aid of Wirless
Technology

5. “Generation of
Wireless Technology

6. 1G WIRELESS
TECHNOLOGY
▸Refers to first generation of wireless telephone
technology,mobile tele communication.
▸Analog signal are used
▸Average rate between 4800 to 9600 bps
▸Based on FDMA
DRAWBACKS
▸ Poor sound quality
▸ No security
▸ Frequent call drops
▸ Limited capacity

7. 2G WIRELESS
TECHNOLOGY
▸ 1991 Finland
▸ Digital Network are used
▸ Enable services
▸ Based on GSM
DRAWBACKS
▸ Require Strong signals
▸ Do not supports high data rates
▸ Unable to handle complex data

8. 3GWIRELESS
TECHNOLOGY
▸ Supports Audio, Video, Graphic
Application
▸ Increased Bandwith
▸ Stable Connection
DRAWBACKS
▸ High Bandwith Requirement
▸ High Spectrum licence
▸ Huge Capital

9. MOTIVATION FOR 4G
RESEARCH
▸ Need of future high performance applications
▸ Need global mobility and service portability
▸ Difficulty in continuously increasing bandwidth
and higher data rate to meet multimedia service
requirements
▸ Need wider bandwidth

11. 4G TECHNOLOGY
▸ High speed data rates
▸ Very stable internet
▸ Fully IP based mobile system
▸ High Speed , high rate, and low cost per bit
▸ Global access, service portability, and
scalable mobile services
▸ Better scheduling
▸ Ad hock and multi hope network
▸ Better spectral efficiency
▸ It use the same tower and fiber cable as
3G.

12. TECHNOLOGY USED IN 4G
▸Smart Antenas (MIMO)
▸IPv6
▸VoIP
▸OFDM
▸Softwre Define Rado System

13. DRAWBACK
▸Battery usage is more
▸Hard to implement
▸Need complicated hardware
▸New technology makes it more expensive
▸Carriers and Providers have to plan carefully to
make sure that expenses are kept realistic.
▸Its available in certain areas

16. CONCLUSION
4G can be described in word “MAGIC”, Which
is stand for:
▸Mobile multimedia
▸Any time, any Where
▸Global mobile support
▸Integrated wireless and personalized services
▸Care
Through 4G is facing challenges and problems we
believe that future research will overcome these
challenge and newly developed service to 4G or
invent 5G networks available to everyone, every time,
every where
