About 4G technology in Nutshell

2.  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.

3.  3G utilized WiMax &WiFi as separate wireless
technologies
 4G is expected to coalesce these two technologies.
 4G will be able to connect various high speed
networks together.
 In 4G HD data will be made available without much
of a problem over the internet.

4.  The 4G system was originally envisioned by the
Defense Advanced Research Projects Agency
(DARPA).
 The DARPA selected the distributed architecture
and end-to-end Internet protocol (IP), and in peer-
to-peer networking.

5.  Two 4G candidate systems are commercially
deployed:
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,
2012.

6.  4G (LTE) is quicker than 3G
 4G holds:
less buffering
better audio quality
improved gaming experience
streaming services with reduced lag.
 Our 4G Plus network uses the 1800 & 2300 MHz frequency
bands
 Our 3G Plus network uses the 900 & 2100 MHz frequency
bands

7.  There are some components which makes the
successful 4G systems they are:
a) OFDMA
b) MIMO
c) IPv6.0
d) Spectral efficiency of 4G
e) SDR(Software Defined Radio)
f) Smart antennas

8. 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
receiver
 range, quality of received signal and spectrum efficiency are
high.

9. IPv6.0:
 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.

10. Smart antenna
 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.

12. UE
eNodeB
SGW(Service gateway)
MME(Mobility Management Entity)
PDN(Packet Data network)

15.  Higher bandwidth
 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.

16.  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.

19.  4G will bring a great revolution in mobile
communication.
 The future of 4G is nothing but 5G.

20.  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
market soon.
