3. WHAT IS WIRELESS?
No physical wired connection between sender and
receiver.
Maintains communication through equipment such as
Routers in place of wires.
Implemented using radio communication(at the
physical layer of the OSI model)
E.g : -Cell phone networks,
-Wi-Fi local networks

TYPES OF WIRELESS NETWORKS
There are Four Types, Based on the size
of Networks :
Wireless LAN
Wireless MAN
Wireless WAN
Wireless PAN
Mobile Phone Networks Like 2G , 3G and
4G uses Wireless WAN Networks

5. In Past Few Decades, Mobile Wireless Technology
have Experience 4 Generations From 1G to 4G.
EVOLUTION OF WIRELESS NETWORKS :
5

6. 1G Wireless
System(FDMA) :
Refers to the First generation.
First Introduced in 1980s and
completed in 1990s.
First Launched In US.
Speed was upto 2.4Kbps.
Focus on Voice
Specific cells operate on
different frequencies to avoid
interference
Uses Analog Signal.
1G TECHNOLOGY
6

7. Poor Voice quality
Poor Battery Life
Large Phone Size
No Security
Limited Capacity
No Roaming Between 1G Operators
DRAWBACK OF 1G TECHNOLOGY
7

8. Refers to the Second Generation.
Based on GSM(Global System For
MobileCommunication).
Primarily Developed in Europe in
early 90s.
Uses Digital Signals.
Speed was upto 14Kbps.
Features :
Enable services such as text messages,
Picture Messages
Voice Was Encrypted
Enabled Roaming
2G TECHNOLOGY
8

9. Requires powerful digital signals
Digital signals could be weak(If
there is less network coverage)
Reduced range of sound/Call Drops
Spotty Coverage/Unable to Handle
Complex Data Such As Videos
DRAWBACKS OF 2G
9

10. It is the Technology Between
2G and 3G.
Sometimes Described as 2G
Cellular Technology Combined
With GPRS
Features :
Send/Receive E-mail messages
Web Browsing
Speed : 64-144 Kbps
EDGE(Enhanced Data For
Global Evolution)
supported.
2.5G TECHNOLOGY
10

11. Refers to the Third Generation.
Introduced in 2000s.
Data Transmission Speed
Increased from 144 Kbps-2 Mbps
Increased Bandwidth.
Typically,Smartphone Network.
Features :
Faster Communication
High Speed Web/More Security
Video Conferencing/3D Gamming
Mobile TV/Broadband Capabilities
3G TECHNOLOGY
11

12. Expensive fees for 3G Licenses
Services
It was Challenge to build the
infrastructure for 3G
High Bandwidth Requirement
Network Fluctuations
Requires Expensive 3G phones.
DRAWBACKS OF 3G
12

13. 4G TECHNOLOGY (ANYTIME,ANYWHERE…)
13

14. Also Known As Fourth Generation Technology
Started From Late 2000s
Capable of Providing 100Mbps-1Gbps speed
Referred as ,
“MAGIC”
M-Mobile Multimedia Connection
A-Anytime/Anywhere
G-Global Mobility Support
I-Integrated Wireless Solutions
C-Customized Personal Service
16
4G TECHNOLOGY
14

15. More Security
High Speed,High Capacity
Low Cost Per Bit
Faster Data Transmission that
of the privious generations.
Clarity in Audio/Video
Support Interactive multimedia,voice,streaming
video and other.
FEATURES OF 4G TECHNOLOGY
15

16. Data Transfer Rate From
2G to 4G
16

17. The goal of 4G is to replace the current core mobile
networks with a single worldwide core network
standard, based on IP for control, video, packet data,
and voice.
WORKING OF 4G

18. 4G MOBILE COMMUNICATION TRANSMISSION
18

19. Also Known As Voice Over LTE
VoLTE systems convert voice
into the data stream
HD Calling
Data And Calling Simultaneously
Higher Bandwidth
4G VoLTE
19

20. Battery usage is more
Hard to implement
Hardware Heating problem
Need complicated Hardware
Expensive equipments required to implement the
structure.
DRAWBACKS OF 4G
20

21. All totally the best way to help all users is to use 4G as the
wireless system and in totally it is safety and secure for public,
“THIS THE NEED , THAT DEMANDS THE SOLUTION”
Todays wired society is going wireless and if it has problem,
4G is the answer.
Now a days 4G technology is giving the tough competition
to the Computers and Laptops.
