3. INTRODUCTION
In recent years, there has been a plenty of paradigm shifts occurring in the way people could connect and collaborate.
Anywhere anytime communication and collaboration are the new norm being prescribed for every individual to be extremely productive.
The fourth generation wireless networks are all set to turn the current networks into end-to-end IP networks.
4G is set to deliver 100mbps to a roaming mobile device globally and upto 1gbps to a stationary device.

4. OG 4G 3G 2G 1G TECHNOLOGY PATH Zero Generation Mobile Systems (0G)
The radio telephone system preceded modern cellular mobile telephony technology (1G).
The radio telephone system contained one central antenna tower per region. The central antenna required radio phones to have a powerful transmitter, capable of transmitting up to 50 miles. The number of radio telephones per region was limited by the number of available channels.
Unlike closed radio systems, radio telephones were connected to the public telephone network and were typically mounted in cars, trucks, and briefcases. 3G 2G 1G OG

5. 1G TECHNOLOGY PATH (Contd…) 4G 3G 2G 0G
First Generation Cellular Communication (1G) 4G
Developed in 1980s and completed in early 1990’s
1G was old analog system and supported the 1st generation of analog cell phones speed up to 2.4kbps
Advance mobile phone system (AMPS) was first launched by the US and is a 1G mobile system
Allows users to make voice calls in 1 country 3G 2G 1G 0G

6. TECHNOLOGY PATH(Contd…)
Second Generation Cellular Communication (2G)
Fielded in the late 1980s and finished in the late 1990s
Planned for voice transmission with digital signal and the speeds up to 64kbps
2G was the digital handsets that we are used today, with 2.5G representing handsets with data capabilities over GPRS 3G 2G 1G 0G

7. TECHNOLOGY PATH (Contd….)
Third Generation Cellular Communication (3G)
Developed in the late 1990s until present day
Transmission speeds from 125kbps to 2Mbps
In 2005, 3G is ready to live up to its performance in computer networking (WCDMA, WLAN and Bluetooth) and mobile devices area (cell phone and GPS) 3G 2G 1G 0G

8. TECHNOLOGY PATH (Contd….)
Fourth Generation Cellular communication(4G)
4G is a research item for next-generation wide-area cellular radio, where you have 1G, 2G, 3G and then 4G [and 5G]
4G is a conceptual framework and a discussion point to address future needs of a high speed wireless network
It offer both cellular and broadband multimedia services everywhere
Expected to emerged around 2010 – 2015
4G will bring almost perfect real world wireless or called “WWWW: World Wide Wireless Web 3G 2G 1G 0G

9. TRENDS OF 4G 4G CHARACTERISTICS CONVERGENCE SERVICES
The idea of convergence is that the creation of the atmosphere that can eventually provide seamless and highly-reliable mobile communication service through wired and wireless convergence networks without the space problem and terrestrial limitation.
In accordance with these trends, mobile network architecture will become flexible and versatile, and new services will be easy to deploy.

10. TRENDS OF 4G (Contd…) BROADBAND SERVICES
Broadband is a basis for the purpose of enabling multimedia communications including video service, which requires transmission of a large amount of data.
4G service application characteristics will give broadband service its advantages.
Low cost
Coverage of Wide Area
Wide Variety of Services Capability

11. TRENDS OF 4G (Contd…) FLEXIBILITY AND PERSONALIZED SERVICE
The key concern in security designs for 4G networks is flexibility.
4G systems will support comprehensive and personalized services, providing stable system performance and quality of service.
At the same time, a low data rate transmission cost will be maintained.
Personal mobility concentrates on the movement of users instead of user’s terminals, and involves the provision of personal communications and personalized operating environments.

12. TECHNOLOGIES INVOLVED IN 4G
3GPP LTE(Third Generation Partnership Programme - Long Term Evolution)
is the name given to a project develops the Universal Mobile Telecommunications System (UMTS) mobile phone standard to cope and manage with future requirements in terms of wireless technology
Objectives include improving efficiency, lowering costs, improving services, making use of new spectrum opportunities, and better integration with other open standards
Download rates of 100Mbps, and upload rates of 50Mbps for every 20MHz of spectrum

13. TECHNOLOGIES INVOLVED IN 4G(Contd…)
WiMax
WiMAX is Worldwide Interoperability for Microwave Access and this technology is a standard created by IEEE to form the IEEE standard
It offers peak data rates of 128 Mbit/s downlink and 56 Mbit/s uplink over 20 MHz wide channels
WiMAX can be thought of as an extension of Wi-Fi designed to enable pervasive, high-speed mobile Internet access on a wide range of devices, from laptops to smartphones.

14. TECHNOLOGIES INVOLVED IN 4G (Contd…)
IEEE
The IEEE or so-called Mobile Broadband Wireless Access (MBWA) specification is also the first IEEE standard that explicitly addresses the needs of mobile clients in moving vehicles.
Whereas e's roaming support is generally limited to local and regional areas, shares with 3G the ability to support global roaming.
Thus, solutions will address the need for a broad spectrum of functionality for mobile business and personal computing implementations.

15. SCENARIOS
Several scenarios are described to display the situations of the wireless communication industry as the 4G.
These scenarios are based on different wireless access technologies such as WiMAX, WiBro, 3G LTE, and IEEE
Option For Evolution Path Towards 4G

16. SCENARIO OUTLINE
In the on-going 4G studies in the standardization bodies and relative industries, one of the aims is to establish an integral wireless system that would seamlessly connect the enhanced forms of existing 3G wireless systems such as WCDMA with HSDPA.
Here existing carriers will maintain present customer base and services are integrated 4G.
4G service will be determined whether it can support 4G characteristics technically, and hold the market with service differentiation from competitors.
In order to forecast the form of realization of 4G systems, we construct four scenarios.

17. SCENARIO OPTIONS

- Comparatively higher cost to use and deploy infrastructure compared fast mobile generation

19. SWOT ANALYSIS – 4G (Contd…)
Opportunities in 4G:
- Evolutionary approach may yield opportunities for the 4G
- It is expected and predicted that consumers will continue to replace handsets with newer technology at a fast rate.
- Desirable higher data capacity rates, the growth opportunity for 4G is very bright and hopeful.
Threats in 4G:
- Faster rate of growth and developments in other region
- Since 3G mobile is still in the market, it squeezes the market competition in the mobile industry.
