This document summarizes a seminar presented by Ved Prakash on 5G technology. It discusses the evolution from 1G to 5G mobile networks, with increasing transmission speeds and capabilities. 5G is expected to offer speeds up to 1 Gbps, make wireless communication almost limitless with technologies like carrier aggregation and small cells, and support applications like wearable devices and media-independent handovers. 5G aims to provide a globally accessible, high-performance wireless network at lower costs than previous generations.

3. INTRODUCTION
 5G Wireless: 5th generation wireless
technology.
 Complete wireless communication with
almost no limitations.
 Can be called REAL wireless world has
incredible transmission speed.
 Concept is only theory not real.

4. 1G
2G
3G
4G
5G

5. 1G
 Developed in 1980s & completed in early 1990s
 Based on analog system
 Speed up to 2.4 kbps
 AMPS (Advance Mobile Phone System) was
launched by the US & it was the 1G mobile system

6. 2G
 Allows user to make voice calls in 1 country
 Developed in late 1980s & completed in late
1990s
 Based on digital system
 Speed up to 64 kbps
 Services such are digital voice & SMS with
more clarity
 Semi global facility

7. 3G
 Developed between late 1990s & early
2000s until present day
 Transmission speed from 125 kbps to
2 Mbps
 Superior voice quality
 Good clarity in video conference
 E-mail, PDA, information surfing, on-line
shopping/ banking, games, etc.
 Global roaming

8. 4G
 Faster & more reliable
 Speed up to 100 Mbps
 High performance
 Easy roaming
 Low cost

9. 5G
 Next major phase of mobile
telecommunication & wireless system.
 10 times more capacity than others
 Expected speed up to 1 Gbps
 More faster & reliable than 4G
 Lower cost than previous generations
 5-G wireless technology is fulfill for “4A
PARADIGM”
 4A paradigm:- “ Any rate, Anytime, Anywhere,
Affordable ”.

10. KEY CONCEPTS ARCHITECTURE
 Real wireless world with no more limitations with access &
zone issues
 Wearable devices
 IPv6, where a visiting care of mobile IP address is assigned
according to location & connected network
 One unified global standard
 Smart radio
 The user can simultaneously be connected with several
wireless access technology
 Multiple concurrent data transfer path

11.  25 Mbps connectivity speed
 Enhanced & available connectivity just
about the world
 Uploading & Downloading speed of 5G
touching the peak (up to 1 Gbps)
 Better & fast solution
 High quality service based on policy to
avoid error
 Support virtual private networks

12. 5G Technologies – How does it work?
5G technology will achieve its expected high efficiency using most modern
modulation techniques and network terminologies like:
1.Carrier Aggregation
Carrier aggregation is a technique used in LTE advanced to improve the
system efficiency. In carrier aggregation, two or more carrier signals are
aggregated to support wider bandwidth which allows even up to 100
MHz.
CA uses three techniques for aggregation:
 Intra-band contiguous: two carriers are transmitted at
neighboring channels (as in the figure).
 Intra-band non contiguous: two carriers are transmitted
with channel spacing.
 Inter-band: In this technique different LTE bands are used for
transmission simultaneously.

13. 2. Small Cell Concept
In order to increase network efficiency, the cell is sub divided into micro and Pico cells.
Spectrum reusability allows to adding more users in a small geographical area and
handle network more efficiently.
3. MIMO Concept
MIMO is a transmission technology with the usage of multiple antennas for transmission
and reception. Simultaneous data transfer is possible using this technology thus offer
efficient data rate. The more the number of antennas, the more transmission and
reception can be done.

14. 4.Wi-Fi off loading
Wi-fi offloading is one the main feature of the future networks. It allows the user to connect
using wi-fi network and the cellular network can be allocated to other users. It would be
suitable for some places where cellular network quality is poor and user still have the option to
connect to the network without cellular reception.
5.Device to device communication
D2D communication is technique where network
authorize two adjacent devices communicate
each other directly. Network will have the control
over the devices and allows an operator to determine
the traffic routing between direct and network path.
During the absents of network, one devices can connect
to another device.

15. Advantages
 More attractive & effective
 Provides subscriber supervision tools for fast
action
 Data BW of 1 Gbps or higher
 Globally accessible
 Dynamic information access
 Available at low cost

16.  Wearable devices with AI (Artificial Intelligence)
capabilities
 Pervasive (Global) networks
 Media independent handover
 Radio resource management
 VoIP (Voice over IP) enabled devices
 With 6th sense technology
 3G- Operator Centric,

17.  4G- Service Centric whereas
 5G- User Centric
 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
