4G is an initialize of the term Fourth-Generation

Communications System.

4G refers to the next generation of wireless

technology that promises higher data rates andexpanded multimedia services.

Fourth generation wireless system is a packet

switched wireless system with wide areacoverage and high throughput.


4/21

The term 4G is used broadly to include several

types of broadband wireless access communication

systems, not only cellular telephone systems.

The approaching 4G (fourth generation) mobile

communication systems are projected to solve still-

remaining problems of 3G (third generation)

systems and to provide a wide variety of newservices, from high-quality voice to high-definition

video to high- data-rate wireless channels.


5/21

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.

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 1Gbps in stationary .8. Seamless Connectivity and Global Roaming across multiple networks.

The first generation -1G was introduced in the early1980s. 1G supported analog signal with the speeds up to2.4kbps.

The second generation- 2G was introduced in the late

1980s.It support digital signal and the speeds up to64kbps.

The third generation- 3G wireless system was developedin the late 1990s .3G provided the transmission speedsfrom 125kbps to 2Mbps & many services, such as global

roaming, good voice and video quality. The fourth generation- 4G is introduced in 2002. The

speeds of 4G can be up to 1Gbps.

The next will be 5G with incredible transmission speedwith no limitation for access and zone size.

1G - Poor voice quality, Poor battery life, Large phonesize, No security, Frequent call drops ,Limited capacity,Poor handoff reliability.

2G - Requires strong digital signals to help mobile phones work. If there is no network coverage in anyspecific area, digital signals would be weak. It do notsupport high data rates. They are unable to handle

complex data such as video.

3G - High bandwidth requirement for High spectrumlicensing fees need big capital.

Smart Antennas for Multiple-input and multiple-output (MIMO).

IPv6 Technology.

VoIP Technology.

OFDM Technology.

Software Defined Radio (SDR) Technology .

“Transmitting & receiving antennas”

Doesn’t require increase power or additional

frequency. Fix no. of beams that can be selected to

follow devices as it moves about. Advantages: Increased capacity, Increased range.

Less power use for transmission , New services,

Increase security .

“ Internet Protocol Version 6”

In the context of 4G, IPv6 support is essential in

order to support a large number of wireless-enableddevices.

IPv6 also enables a number of applications with

better multicast, security, and route optimizationcapabilities.


14/21

“Voice Over Internet Protocol”

Allows only packets (IP) to be transferred

eliminating complexity of 2 protocols over the same

circuit. All voice data will be wrapped up in a packet - faster transmission. Samples voice between

8,000 & 64,000 times per second and creates stream

of bits which is then compressed and put into a

packet. Increases battery life due to greater datacompression .


15/21

Affordable communication services.

High speed, high capacity and low cost per bit.

Support for interactive multimedia, voice , streamingvideo, Internet and other broadband services.

Global access, Service portability and scalable mobile

services and variety of quality of services provided.

Better spectral efficiency.

Seamless network of multiple protocol and air

interfaces.


16/21

Battery usage is more.

Hard to implement.

Need complicated hardware.

The equipment required to implement a next

generation network is still very expensive.

Carriers and providers have to plan carefully

to make sure that expenses are kept

realistic.


17/21

4G is coming quicker.

Fast internet access to both stationery and mobile users.

4G can be efficiently combined with cellular

technologies to make consistent use of smart phones andalso create video blogs.

This gives the manufactures the opportunity to produce

more affordable user friendly 4G compatible devices.

4G is capable of providing new horizon of opportunityfor both existing and startup telephone companies.


18/21

The applications of 4G are called “KILLER

APPLICATIONs” as it is going to bring to

revolution in the internet world.

1) High Speed Data Rate due to which a moviecan be downloaded in 2 to 3 minutes.

2) More Security.

3) Video Conferencing.4) Higher Bandwidth.

5) Global Roaming.


19/21

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 ofwireless communication that will change the

people’s life in the wireless world.

4G is expected to be launched by 2010 and the

world is looking forward for the most intelligent

technology that would connect the entire globe.
