INTRODUCTION TO 5G
EVOLUTION FROM 1G TO 5G
KEY CONCEPTS ARCHITECTURE
HOW 5G TECHNOLOY WORKS
5G Wireless: 5th generation wireless
Complete wireless communication with
almost no limitations.
Can be called REAL wireless world has
incredible transmission speed.
Concept is only theory not real.
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
Allows user to make voice calls in 1 country
Developed in late 1980s & completed in late
Based on digital system
Speed up to 64 kbps
Services such are digital voice & SMS with
Semi global facility
Developed between late 1990s & early
2000s until present day
Transmission speed from 125 kbps to
Superior voice quality
Good clarity in video conference
E-mail, PDA, information surfing, on-line
shopping/ banking, games, etc.
Faster & more reliable
Speed up to 100 Mbps
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
4A paradigm:- “ Any rate, Anytime, Anywhere,
10. KEY CONCEPTS ARCHITECTURE
Real wireless world with no more limitations with access &
IPv6, where a visiting care of mobile IP address is assigned
according to location & connected network
One unified global standard
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
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:
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
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
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.
More attractive & effective
Provides subscriber supervision tools for fast
Data BW of 1 Gbps or higher
Dynamic information access
Available at low cost
16. Wearable devices with AI (Artificial Intelligence)
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
