Evolution of 4G technology in Mobile Communication

Friends here I am discussing about the upcoming 4G technology??..I asked one of my friend

what is 4G technology ?and

answer is: ??What the F*_**K is this 4 G ??network. I just know that there are now 3G sims in trend and after sometime 4G sims are in demand.?

Mobile communication and wireless networks are developing rapidly, which has resulted in huge growth in areas of mobile subscribers and terminals, mobile and wireless access networks, mobile services and applications. Now the question is what is 4G??? and the answer is :

4G wireless technology offers higher data rates and the ability to roam across multiple heterogeneous wireless networks.

Broadband(signals over a wide range of frequencies in high-capacity telecommunications in high capacity) is the basis for enabling multimedia communications, including video service, which requires transmission of large amount of data. Based on pocket transport, integration of various media on different qualities is done. The increasing amount of broadband services like Asymmetric Digital Subscriber Line(ADSL) and optical fiber access systems and office or home LANs are expected to lead to the demand for similar services in mobile communication environment. 4G service application characteristics will give broadband services its advantages.

4G mobile systems will mainly be characterized by horizontal communication model, where such different access technologies as cellular, cordless, wireless LAN type system, short range wireless connectivity and wire systems will be combined on a common platform to complement each other in the best possible way, for different service requirements and radio environments.

4G systems will support comprehensive and personalized services, providing stable system performance and quality of service. To support multimedia services, high system reliability will be provided. At the same time, a low data rate transmission cost will be maintained. In order to meet demands of diverse users, service providers will be required to design personal and customized services for different customers. However, one major concern in security designs for 4G networks is its flexibility.

4G network in the world

MAJOR ADVANTAGES OF 4G TECHNOLOGY

• Reduced need for hardware site upgrades, which is turn decreases operational expenditure.
• Rise in usage of accessible network elements will help to decrease capital expenditure.
• Superior space efficiency.
• Open system architecture and faster time to market new services and applications, resulting in decrease in number of separate platforms.

It is said that based on the advantage trends in mobile communication world, 4G will have broader bandwidth, higher data access, smoother and quicker handoff, wider mobile area and lower cost. Anyone of us will be able to communicate with anyone else, anywhere and anytime, or enjoy any service of any network service provider.

Docomo, Japan, has been investigating 4 G mobile telephony since 1998. In India AIRTEL become the first company in India to offer high-speed Internet services using fourth-generation (4G)

4G is expected to have 5 times faster than 3G???really exciting???.
