Introduction of 5G
4
- 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.
What does it offer ?
5
 Worldwide cellular phones.
 Extraordinary data capabilities.
 High connectivity.
 More power & features in hand held phones.
 Large phone memory, more dialing speed, more
clarity in audio & video.
6
Why we need 5G ?
▪ Due to drawback of other generation.
▪ They have low speed , poor voice and video quality as 5G.
Evolution
7
th
0 Generation
▪ Pre-cell phone mobile telephony technology, such as radio telephones that
some had in cars before the arrival of cell phones.
▪ Communication was possible through voice only.
▪ These mobile telephones were usually mounted in cars or trucks.
▪ Technologies :
- PTT(Push to Talk)
- MTS (Mobile Telephone System)
- IMTS (Improved MTS)
8
0th Generation
▪ First mobile radio
telephone In 1924.
1st
9
Generation
“A voice call gets modulated to a higher frequency
of about150MHz and it is transmitted between radio
towers. This is done using a technique called
Frequency-Division Multiple Access (FDMA).”
10
Continued…..
▪ Technologies:
- FDMA (Frequency Division Multiple Access)
- NMT (Nordic Mobile Telephone)
- AMPS (Advanced Mobile Phone System)
▪ Problems :
- No security
- Prone to distortions
11
Drawback of 1st G
▪ Poor battery
▪ Poor voice quality
▪ Large in size
▪ No security
▪ Frequency call drop
2nd
12
Generation
▪ Digital cell phones
▪ Speed: 10kbits/sec
▪ Time to download a 3min MP3 song: 31- 41 min
▪ Different Services :
- Digital voice calling
- Short message service (SMS)
▪
Standards:
- GSM
- CDMA
- TDMA
13
Drawback of 2G
▪ Weaker
digital signal
▪ Due to rapid changes in user
expectation, they do not meet
today's wireless need.
▪ These systems are unable to handle
complex data such as Videos.
▪ Low voice data & slow
transmission.
▪ Reduce range of sound
14
3rd Generation
“ 3G networks provide the
ability to transfer voice data &
non-voice data over the same
network simultaneously.”
Speed: 144kb/sec-3mb/sec i.e. 1
million bits, or 125,000 bytes, of
data are being transferred per
second .
▪ Time to download a 3min MP3
song:
▪ 11sec-1.5min
Applications
▪ The aim of the 3G is to allow for
more coverage and growth with
minimum investment.
▪ Internet, e-mail, fax, e-commerce,
music, video clips, and
videoconferencing.
15
Continued……
Features includes:
- Phone calls
- Global roaming, GPS
- Send/receive large email messages
- High-speed Web, Navigation/maps
- Video conferencing
- Electronic agenda meeting reminder
16
Drawback of 3G
▪ High Bandwidth Requirement
▪ Expensive 3G Phones.
▪ Large Cell Phones
17
4th Generation
▪“The word “MAGIC” also refers
to 4G wireless technology which
stands for Mobile multimedia,
Any-where, Global mobility
solutions over, Integrated
wireless and Customized
services.”
▪ Speed:
▪ The data transfer is 100 Mbps
for outdoor and 1Gbps for
indoor.
18
Continued…..
Features include:
- A spectrally efficient system
- High network capacity
- Huge data rate
- Perfect connectivity & global roaming
- High quality of service, Security & Privacy
▪
19
Drawback of 4G
▪ Battery uses is more
▪ Hard to implement
▪ Need complicated hardware
▪ Expensive equipment
required to implement next
generation network.
Standard of WIRELESS 5G
20
- 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.
Continued…..
21
- 3GPP LTE a project aims to improve the
mobile phone standard to cope with future
requirements.
- 5GPP 2 UMB a project to improve the
CDMA 2000 mobile phone standard for next
generation applications.
Features of 5G
23
High resolution for crazy cell phone users

26
Conclusion
▪ 3G- Operator Centric
▪ 4G- Service Centric
▪ 5G- User Centric.
▪ 5G can serve as a flexible platform.
▪ We have proposed 5G wireless concept designed as an open platform
on different layers.
▪ The new coming 5G technology will be available in the market at
affordable rates, high peak future & much reliability than preceding
technologies
