4G-4th Generation of mobile communication.
A descendant to 2G and 3G technology aiming to
provide the very high data transfer rates.
Best described in one word “MAGIC”.
MAGIC Mobile multimedia Anytime
Anywhere Global mobility support, integrated
wireless and personalized services.
3G utilized WiMax &WiFi as separate wireless
4G is expected to coalesce these two technologies.
4G will be able to connect various high speed
In 4G HD data will be made available without much
of a problem over the internet.
The 4G system was originally envisioned by the
Defense Advanced Research Projects Agency
The DARPA selected the distributed architecture
and end-to-end Internet protocol (IP), and in peer-
Two 4G candidate systems are commercially
Mobile WiMax standard
Long Term Evolution (LTE) standard
Bharti Airtel launched India's first 4G service,
using TD-LTE technology, in Kolkata on April 10,
4G (LTE) is quicker than 3G
better audio quality
improved gaming experience
streaming services with reduced lag.
Our 4G Plus network uses the 1800 & 2300 MHz frequency
Our 3G Plus network uses the 900 & 2100 MHz frequency
There are some components which makes the
successful 4G systems they are:
d) Spectral efficiency of 4G
e) SDR(Software Defined Radio)
f) Smart antennas
OFDMA: Orthogonal Frequency Division Multiple Access.
It captures entire energy
Only few signals are affected or lost in OFDM while
compared to CDMA in 3G.
MIMO(Multi Input Multi Output):
improve the communication performance between sender and
range, quality of received signal and spectrum efficiency are
Allows more address than IPv4.0
IPv6 each device have own IP address.
SDR(Software Defined Radio):
A SDR will allow increasing network capacity
at specific time.
Switched Antenna: Based on the requirement of the
system ,signal is received at any given time.
Adaptive Antenna: Steer the signal at any direction
of interest ,nullify the interfering signal.
Better response time. 10 times better then 3G
Works at 2.6GHz frequency
Less time to build 4G
It use the same tower and fiber cables as 3Gs - they
only have to upgrade the towers with 4G components.
New technology which makes it more
expansive than 3G
It is impossible to make our current equipment
to be compatible with 4G.
It is available in certain cities within US.
4G will bring a great revolution in mobile
The future of 4G is nothing but 5G.
4G technologies was still at research stages in
many of the countries.
Companies like NTT Do Como Mobile and Nortel
Networks, and Nokia Siemens Networks
successfully demonstrated the working of4G.
This technology will be deployed in the world
