INTRODUCTION

4 G TECHNOLOGY IN INDIA WAS INTRODUCED OR LAUNGED

BY BHARITI AIRTEL IN KOLKATA ON APRIL,10,2012.

IT IS IN INDIA AVAILABLE AT

BANGALORE,PUNE,CHANDIGARH,KOLKATTA

ITS FREQUENCY IS #40(2.3GHZ)

IT SUPPORTS QUALITY OF SERVICES.

QUALITY OF SERVICES CHALLENGES

1.Multi-access interface, timing and recovery.

2. Higher frequency reuse leads to smaller cells that may causeintra-cell interference or higher noise figures due to reduced

power levels.

3. The Digital to analog conversions at high data rates, multiuser

detection and estimation (at base stations), smart antennas and

complex error control techniques as well dynamic routing will

need sophisticated signal processing.

4. Issues in the interface with the ad hoc networks should be

sorted out. 4G systems are expected to interact with other

networks like the Bluetooth, hiperlan, IEEE802.11b, etc.

5. Voice over multi-hop networks is likely to be an interesting

problem because of the strict delay requirements of voice.7. Security will be an important issues

8. Networking protocols that adapt dynamically to the changing

channel conditions.

9. Seamless roaming and seamless transfer of services.

What is 4G?

Fourth Generation Technology

Faster and more reliable

100 Mb/s

Lower cost than previous generations Multi-standard wireless system

Bluetooth, Wired, Wireless

Ad Hoc Networking

IPv6 Core

OFDM used instead of CDMA

Potentially IEEE standard 802.11n

Most information is proprietary

Communication Architecture

Broadcast layer: fix access points, (i.e.) cell tower

connected by fiber, microwave, or satellite

(ISP) Ad-hoc/hot-spot layer:

wireless LANs (i.e. internet at Starbucks)


11/18

communication Architecture

Personal Layer Gateway:

devices that connect to upper layers; cell phone,fax, voice, data modem, MP3 players, PDAs

Info-Sensor layer: environmental sensors

Fiber-optic wire layer:

high speed subterranean labyrinth of fiber opticcables and repeaters

communication

in networking

multimedia

communication

in

modems,cellphones

cloud computing

LIMITATION Carriers and

providers have to plan

carefully to make sure

that expenses are

kept realistic

OUR VIEW ABOUT 4G

it has large application good connectivity

access speed is good

broadband mobility access

it is good but the limitation of 4g should o

overcomed for the improvement of 4g

TECHNOLOGIES AFTER 4G

5G technology offer high resolution for crazy cell phone user and bi-

directional large bandwidth shaping.

The advanced billing interfaces of 5G technology makes it more

attractive and effective.

5G technology also providing subscriber supervision tools for fast

action.

The high quality services of 5G technology based on Policy to avoid

error.

5G technology is providing large broadcasting of data in Gigabit

which supporting almost 65,000 connections.
