4 g technical paper presentation

Presented By: Gaurav Narkhede Prabhat Shukla Swapnil More Nikita Patil

Introduction 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. Customized personal service.

Magic of 4G Technology

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.

History

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.

Commercial Deployment

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.

Why 4G over 3G? 4G (LTE) is quicker than 3G  4G holds:

less bufferingbetter audio qualityimproved 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

Components of 4G

There are some components which makes the successful 4G systems they are:

a) OFDMAb) MIMOc) IPv6.0d) Spectral efficiency of 4Ge) SDR(Software Defined Radio)f) Smart antennas

Components (contd..)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.

Components (contd..)

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.

Components(contd..)

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.

PDN(Packet Data network)

3G Vs 4G

4G working:

Advantage of 4G

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. 

Disadvantage of 4G

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.

Conclusion 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.

4G can be quoted as :

“Every one, Anytime & Every

Where”
