3. SCENARIOS AND APPLICATIONS

STAGE PRESENTATION:
A key feature of 4G is likely that the availability of data rates significantly higher than those of third generation (3G). It has been suggested that transmission rates of up
100 Mbps for high mobility and 1 Gbps for low mobility should be the target value. These types of data suggest a greater spectrum efficiency and lower cost per bit will be a key requirement for these systems in the future. Other important elements and it is expected that it may increase the flexibility of mobile terminals and networks, multimedia facilities and connections for high data rate. Future systems convergence will, of course, other characteristic. On the basis of these views and characteristics of the 4th generation (4G) wireless telecommunications future, re-issue of spectrum allocation, and feasibility of the technology, the advent of 4G service will bring a series of environmental changes competitive environment, regulation and policies, and changing wireless communication service in the future. It is therefore very important that we hope that kind of chance we have to prepare well for 4G service.



ROUTE OPTIONS evolution towards 4G



Several scenarios are described to show the status of the wireless communications industry as the 4G. These scenarios are based on different wireless access technologies such as WiMAX, WiBro, 3G LTE and IEEE802.20. In ongoing studies in the standardization of 4G industries and related bodies, one of the objectives is to establish a comprehensive system that seamlessly connects wireless improved forms of existing wireless systems such as 3G WCDMA, HSDPA.In this scenario, existing companies will maintain current customer base and integrated 4G services. On the other hand, however, has been made possible by technological innovation that 3G wireless services are not developed as competitors against the 3G services such as WiMAX, or IEEE increase of more than 802. In addition, individuals and organizations have begun to provide wireless communication open and free through the opening, through various technologies. Figure 2 shows that these different evolution path to 4G. For the scenarios provided in the document, it was assumed that the arrival of 4G service will be after 2012. 4G service will determine whether you can technically support 4G characteristics, and keep the market with service differentiation from competitors. In order to provide the embodiment of 4G systems, construct four scenarios in the paper.

Applications
• Voice
The voice is and remains the most important type of application in mobile telecommunications.

The most important features of ASCI include the following:
Voice service (VBS): the ability of a single phone to talk to a group of mobile;
group voice call services (VGCS): the ability of a group of mobile phones to talk to each other;
High priority and priority multilevel (EMLPP): The fact that emergency calls can anticipate less urgent calls.
• Messaging
• Multimedia Messaging Services (MMS)
- The text, sounds, images and video
- Transition from Short Message Service (SMS)
- Open Internet standards for messaging
• Internet Access


• Web Applications
- Information Portals
- Wireless Markup Language (WML) with signs of use of Wireless Application Protocol (WAP)
• location-based applications
➢ Emergency Services
• E911 - Enhanced 911
➢ The added value of personal services
• Friend Finder, directions
➢ Commercial Services
• Coupons or offers from local shops
➢ internal network
• Traffic and coverage of measurements
•
• lawful interception Extensions
➢ location (in 3D), speed and direction
• With date and time
➢ The measurement accuracy
➢ Response Time
• a measure of quality of service
➢ Security and Privacy
• Authorized clients, secure information exchange,
Control privacy by the user and / or operator

• Games
➢ Games will be another important application segment 3G/4G.


• Electronic Agents
➢ electronic agents are supposed to play an important role in mobile working in the future - as the agents are sent to carry out searches and tasks on the Internet and inform their owners.
➢ They e-care, e-secretaries, e-consultants, administrators, mailing, etc. This type of control is what we expect home automation applications.

• Requests for appointments
➢ These are already very popular in Asia.
➢ It can be a simple bulletin board with announcements of appointments in combination with an anonymous e-mail server, or it could be one heart-mobile chat room.



Strengths, Weaknesses, Opportunities and Threats of 4G

Considering the features of 4G, which is expected scenarios and market trends and applications, we can find the strengths, weaknesses, opportunities and threats of 4G with a better understanding. The lists and tracking results.

Strengths in 4G:
➢ 4G visions take into account the installed base and past investments
➢ Strong position of telecommunications providers in the market expected.
➢ faster data transmission and higher bit rate and bandwidth, allowing more business and marketing applications
➢ It has advantage to customize multimedia communication tools

Weakness in 4G:
➢ No large community of users advanced mobile data applications even
➢ The growing gap between vendors and telecom operators
➢ You may not offer full Internet experience because of the limited speed and bandwidth
➢ comparatively higher cost for the use and deployment of infrastructure compared accelerated generation mobile


Opportunities in 4G:
➢ evolutionary approach can provide opportunities for 4G
➢ The emphasis on heterogeneous networks leverages past investments
➢ Strategic Alliance coalition and opportunities for traditional telecommunications industries not
➢ sophisticated and mature commercialization of 4G technology
➢ encourage more applications from e-commerce and m-commerce
➢ stimulates consumption global economy and restore consumer confidence, thus putting into opportunities for the telecommunications
➢ It is hoped and predicted that consumers will continue to replace terminals with new technologies at a rapid pace.
➢ desirable higher rates of data capacity, the growth opportunity for the 4G is very bright and hopeful.

Threats on 4G:
➢ fastest rate of growth and evolution of another region
➢ From the 3G mobile is still in the market, tightening the market competition in the mobile industry.
