3. WiRELESS Network
1
 No physical wired
connection.
 Communication via
Radio waves or
Microwaves.
 Reduces cost of
installing cables.
 Examples are cell phone
networks, satellite
communications, etc.

4. CELLULAR NEtWORK
2
 A type of Radio
Network.
 Base cells are served
with Transceivers
known as Cell Site.
 Last link used is
wireless connection.
 Large coverage area.
 Reduced interference.

6. 1G technology
 1G was first introduced in 1980s and completed
in early 1990s.
 It’s speed was upto 2.4Kbps.
 It allows the voice calls in 1 country.
 1G networks use analog signals.
 AMPS was first launched in 1G mobile systems.

7. LImitations of 1G
 Poor Voice Quality
 Large Phone Size
 No Security
 Limited Capacity
 Poor Handoff reliability
1G wireless system

8. 2G technology
 2G is based on GSM.
 Launched in Finland in 1991.
 2G network use digital signals.
 It’s data speed was upto 64Kbps.
 Enables SMS, picture message and MMS(Multi
Media Message).
 Provides better quality and capacity.

9. limitations of 2G
 2G requires strong
digital signals .
 Unable to handle
complex data such as
Videos.
 Less compatible with
smart phones functions.
2G wireless system

10. 3G technology
 3G technology was introduced in year 2000s.
 Data transmission speed increased from
144Kbps to 2Mbps.
 Increased bandwidth and data transfer rates.
 Compatible with smart phones.
 Provides Web-based applications.

11. Features of 3G technology
 Providing faster communication.
 Send/Receive large E-mail messages.
 High speed web/ More security/ Video
Conferencing/ 3-D Gaming.
 TV streaming/ Mobile TV/ Phone Calls.
 Large Capacities & Broadband Capabilities.
 11 sec-1.5 min time to download a 3 min MP3
song.

12. limitations of 3G
 Expensive fees for 3G
Licenses Services
 It was a challenge to build
the infrastructure of 3G
 High Bandwidth
Requirement
 Expensive 3G Phones
 Large Cell Phones

13. 4G technology
 4G was started from late 2000s.
 Capable of providing 100Mbps-1Gbps speed.
 4G can be described using MAGIC:
Mobile Multimedia
Anytime Anywhere
Global Mobility Support
Integrated Wireless Solution
Customized Personal Services
 Also known as LTE (Long Term Evolution)
11

14. Features of 4G technology
 Higher data rates and expanded multimedia
services
 High QOS and high security
 Large capacities and Broadband capability
 Low cost per bit
 Approximately 10 times faster than 3G
 Supports the global access , the service
portability & scalable mobile services
12

15. limitations of 4G
 Must buy new devices for
4G.
 Higher data prices for the
services (expensive).
 Needs complex hardware.
 Uses many antennae &
transmitters thus poorer
battery life.
 Requires expensive
infrastructure for operation13

16. 5G technology
 5G was started from late
2010s.
 Complete wireless
communication with almost
no limitations.
 It is highly supportable to
WWWW(Wireless World
Wide Web).
 Aims at higher capacity than
current 4G, allowing a
higher density of mobile14

17. Features of 5G technology
 High Speed, High Capacity.
 Provides large broadcasting of data in Gbps.
 Multi-Media Newspapers, watch T.V. programs
with high clarity and HD quality.
 Faster data transmission compared to that of
previous generations.
 Large phone memory, dialing speed, clarity in
audio/video.
 Support interactive multimedia, voice, streaming
video, Internet & other.15

18. conclusion
 All totally the best way to help all users is to use
5G as the next wireless system and in totally it is
safe and secure for public this the need that
demand the solution.
 5G technology is going to give tough
competition to computers and laptops.
 It will be available in the market in 2020 at
affordable cost with more reliability than
previous generations wireless systems.
