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 solution, and Customized personal service.

OBJECTIVE

4G is being developed to accommodate the Quality of Service (QOS) and rate requirements set by forth coming applications like 1. MMS (Multimedia Messaging Service). 2. Wireless Broadband Service. 3. Video Chat. 4. Mobile TV. 5. Digital Video Broadcasting. 6. High Network Capacity. 7. Data Rate of 100 Mbps for mobile and 1 Gbps

while stationary . 8. Smooth handoff across heterogeneous

network.. 9. Seamless Connectivity and Global Roaming

across multiple networks.

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

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.

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.

SMART ANTENNAS:• 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.

APPLICATION

The applications of 4G are called “KILLER APPLICATIONs” as it is going to bring to revolution in the internet world. Better use of Multimedia Application More Security. Video Conferencing. Higher Bandwidth. Tele-geoprocessing like GIS,GPS. Traffic control

4G WORKING AREA

CONCLUSION

As the history of mobile communications shows, attempts have been made to reduce a number of technologies to a single global standard.

4G seems to be a very promising generation of wireless communication that will change the people’s life in the wireless world.
