This slide made by Taifur Rahman and its quite good about 4G Network. We describe not only 4G but also 1G, 2G, 3G, 4G LTE

SHORT HISTOR OF G’S
DETAILS OF 4G
HOW 4G WORKS
4G VS LTE

4. 1G
Based on Analog Telecommunication Standards.
Started in 1980s in Europe & USA.
Used Analog Radio signals.
Range: 2.9KB/s to 5.6KB/s.
First ever (cordless)phone to work on 1G network was
Motorola DynaTAC 8000X.

6. 2G
Started in 1991 in Finland.
Based on GSM (Global System for Mobile Communications) Technology.
Used Digital Radio signals and SIM(Subscriber Identity Module) card.
Range : 15kB/s to 40kB/s

8. 3G
It was developed in the late 1990s until present day.
Japan is the first country having introduced 3G nationally.
Data Transmission speed increased from 144kbps- 2Mbps.
Typically called Smart Phones and features increased its
bandwidth and data transfer rates to accommodate web-based
applications and audio and video files.
UMTS (Universal Mobile Telecommunications System ) is an upgrade from GPRS
(General Packet Radio Service) with much more bandwidth.
Range of 3G(UMTS):
144kB/s 384kB/s in rural.
384kB/s to 27MB/s in urban.

10. 4G
Latest and Fastest Generation of mobile phone
communication.
Based on same 3G Technology with improvements named as
LTE.
First used in 2009 in Sweden.
Range: 100MB/s to 1GB/s.

14. 4G (Anytime, Anywhere)
One of the basic term used to describe 4G is
MAGIC.
MAGIC:
Mobile Multimedia
Anytime Anywhere
Global Mobility Support
Integrated Wireless Solution
Customized Personal Services
AKA Mobile Broadband Everywhere.

LTE -LONG TERM EVOLUTION

17. Older networks use circuit-switching technology, a term that refers to the method of communicating. In a
circuit-switching system, a connection is established directly to the target through the network, and the
entirety of the connection, whether it’s a phone call or a file transfer, happens through that connection.
The advantages of a circuit-switched network include a faster connection time and less chance of the
connection dropping.
Newer networks take advantage of packet-switching technology, a modern protocol that takes advantage
of the much larger number of connected points across the globe. In a packet-switching network, your
information is broken up into small chunks which are then sent to your destination over whatever path is
currently the most efficient. If a node drops out of your connection in the circuit-switching networks, you’ll
have to reconnect, but in a packet-switching network, the next packet will simply hunt for a different path.

18. Dedicated Bandwidth

19. BASIC 4G NETWORK

21. Drawback Of 4G
1. Battery uses is more
2. Hard to implement
3. Need complicated hardware
4. Expensive equipment required to implement next generation
network.

22. Analyzing between G’s

24. 4G Vs LTE
The ITU-R set standards for 4G connectivity in March of 2008. But at that moment the world is lacking far
behind of hardware and network properties for 4G.
So every company start race to develop 4G and they called it LTE (Long Term Evolution).
In the mean time 3G was developing rapidly and its speeds grow tremendously.
ITU-R thought the real 4G will take so much time to arrive and they came to an conclusion that newly
developed LTE operator's can call them 4G if they can provide better speed than 3G or more that 5 mega
bit/s. After the announcement all the operator company which ware working on LTE change there name to
4G LTE.
Now we know 3G speed starts from 384 kilo bits/s and 4G speed starts from 5 mega bits/s.
But the fun fact is high speed 3G network can now give 20/22 mega bits/s which can be beat 4G LTE
network.

25. Global Consumption of Gs

26. What’s next?
Carriers are already testing the fifth generation of mobile broadband connectivity,
5G, but there’s a lot still to work out. There’s no agreed upon standard as yet, and
we’re not likely to see 5G starting to roll out until at least 2020. Judging by what has
happened with 4G, it could also be several years beyond that before it’s widely
available.

27. That is all
