3. 1st GENERATION:
Introduced in 1980
Analog cellular mobile,Data speed 2.4kbps
1G mobiles- AMPS,NMT,TACS
Uses FDMA technique with 30KHz
4. 2nd GENERATION:
Lunched in 1991
Digital cellular systems
Digital modulation schemes-TDMA,CDMA
Data speed in 2g is up to 64kbps
Data speed in 2.5g is up to 144kbps
GPRS, EDGE and CDMA 2000 were 2.5
technologies.
5. 3rd GENERATION:
Invented in 2000
3g technology is intended for true
multimedia cell phone
typically called smart phones and features increased
bandwidth and transfer rates to accommodate wed-
based applications and phone-based audio and video files
• Advantages
universal global roaming
• multimedia (voice , data & video)
384 kbps while moving
2mbps when stationary at specific locations
video calling
6. 4th GENERATION:
Introduced in 2000
high-speed data access
high quality streaming
video
combination of wi-fi and
wi-max
SDR ,OFDM,OFDMA
and MIMO
7. WHAT IS 5G???
5G is a packet switched
wireless system with wide
area coverage and high
throughput.
5G wireless uses OFDM and
millimeter wireless that enables
data rate of 20 mbps and
frequency band of 2-8 GHz.
5G is going to be a packed
based network.
8. OBJETIVES OF 5G:
5G being developed to accommodate QoS rate
requirements set by further development of existing 4G
applications.
Flexible channel bandwidth between 5 and 20MHz,
optionally up to 40MHz.
Data rate of at list 1Gb/s between any two points in
the world
Increase system spectral efficiency of up to
3bit/s/Hz/cell in the downlink and 2.25bit/s/Hz/cell
for indoor usage.
9. STANDARD WIRELESS 5G:
• WiMAX formed to provide conformance and interoperability of the
IEEE 802.16 standard. It aims to provide wireless data over long
distance from point-to-point link to cellular mobile type access.
• WiBRO a part of IEEE 802.16e in process to provide collaborative
and generic mobile WiMAX.
• 3GPP LTE a project aims to improve the mobile phone standard to
cope with future requirements.
• 5GPP 2 UMB a project to improve the CDMA2000 mobile phone
standard for next generation applications.
10. IPv6 SUPPORT:
• IPv6 increases the IP addresses size from 32bit to 128 bits, to support
more levels of addressing hierarchy and much greater number of
addressable node.
• IPv6 support large number of wireless enabled devices.
• IPv6 Extend the IP address space enough to offer a unique IP address
to any device.
• IPv6 Improve support for IP Mobility.

12. BENEFITS OF 5G:
High speed, high capacity, and low cost per bit.
Support interactive multimedia, voice, streaming video, Internet, and other
broadband services ,more effective and more attreactive ,Bi directional
,accurate traffic statistics.
Global access, service portability, and scalable mobile services.
The high quality services of 5G technology based on Policy to avoid error.
5G technology is providing large broadcasting of data in Gigabit which
supporting almost 65,000 connections.
5G technology offer transporter class gateway with unparalleled
consistency.
Through remote management offered by 5G technology a user can get better
and fast solution.
13. CONCLUSION:
• Migration to 5G networks ensures convergence of networks,
technologies, applications and services.
• 5G can serve as a flexible platform.
• Wireless carriers have an opportunity to shorten Investment return,
improve operating efficiency and increase revenues.
• 5G - a promising Generation of wireless communication that will
change people’s lives.
