4G Wireless







"Some men and women see things as they are and say why;" said George Bernard Shaw.

A few years from now, the whole world would be connected wirelessly with a number of satellites. Instead of tracking the itinerary in developed countries, developing countries would go to the most modern technology and go wireless. If the poor in the world also get the power of cheap wireless technology, including toll free numbers, to talk to their governments and order economic development tools such as bank loans, roads, schools, and hospitals. Wireless freedom would increase millions of entrepreneurs. The problems that micro-enterprises faced in addressing the vulnerability of accessing the larger public market and its market information would overcome, profitable channels to reach the world's consumers. Farmers and fishermen can discover markets and present where they can get the best value for their products. This will provide a significant opportunity for the poor to rise from poverty.

Going wireless in the rural segment will be that the message will spruce down rural areas into urban migration by creating better employment and livelihoods in rural areas through small businesses and micro enterprise improvements. Micro-business owners can turn their revenue into revenue-generating units by seamlessly registering product information into large online markets without the need for computers, the technical and social-economic gaps created by the digital divide will come out.

It would allow immediate access to help during civil emergencies and natural disasters, saving thousands of lives. Wireless communication will increase access to healthcare services in the world's most remote corners. Telemedicine services, including remote diagnosis and treatment advice and increased access to current market and price information, become the norm. Wireless communication will to a large extent reduce opportunities for transactions for farmers and rural-based traders. It will support educational services including distance learning and improve the control, openness and efficiency of a range of public services through rural information systems helping millions advance in life. Hope it will raise the standard of living throughout the world.

4G Wireless

4th generation wireless standard is developed. Once completed, it would change how we live our lives. 4G Wireless mobiles would be petita enough to fit in a palm and light in mass like a pen and the gadget would be a complete mobile home cinema experience, download a complete high-resolution movie, have a mobile phone with data transfer rates of more than 100 Mbps. microprojector that can display the film on a flat surface, a digital film can be seen on it with effects that apparently give a 3D experience.

Every content can be downloaded wirelessly clean need to buy newspapers and magazines. The device can be used to make purchases (charges go to the mobile instead of the credit card); And it can be used for many other activities where money is needed. A sales manager can ask if you should charge the card or mobile. The mobile would be our ears and eyes and would be so "intelligent" and "prescient" that it would not only warn us about the next big sale or the best price for the car model number one, but also warn us how weak the fish was or warn us about the shooter in the dark or in the landslide forward.

These mobiles can be used for daily life activities, such as controlling various household appliances such as AC, Rice Cookers, Refrigerators etc, as well as being used for Working with custom functions depending on user requirements, nursing and health care will change dramatically, doctors will be able to Perform routine checks of patients from real-time portable mobiles or respond immediately in the event of an emergency. A doctor can give first aid directives by seeing the patient on the screen.

Medical data can be transferred immediately to an ambulance or hospital. A person can be placed exactly from the mobile phone he carries. These mobiles can also be used in disaster management by enabling the transfer of real-time data from disaster areas, giving people freedom from time, space and user function. The cost of this mobile and its communication capabilities will be so low that the world's poorest people will rush to cope with the technology because of its benefits.

4G Wireless Research.

Research on 4G Wireless has been going on for the past few years. These networks promise a much higher overall data flow and much more versatile services than current and third (2G-3G) networks can do. All-IP Wireless has become the most favored platform for 4G wireless networks. In planning the future wireless network architecture, one must take into account the fact that the primary load in 4G wireless networks will be high-speed, rich, inaccessible traffic, which has previously been a major challenge for any existing wireless network
Technologies used in existing networks. Many research activities investigate the design of capable architectures for 4G wireless networks, which are skilled, adaptive, flexible, and scalable. It works harmoniously with various network technologies (including older 2G, 2.5G and 3G networks) and allows heterogeneous network applications. The research is to investigate how to realize smooth migration and seamless interoperability between the old networks and future 4G wireless networks.

4G Architecture.

It has been recommended that the architecture of 4G wireless networks effectively address all the limitations and problems of the current wireless networking technology. The research of next-generation wireless networking targets is aimed at many cutting-edge topics, such as sharp joint optimization design, quality assurance of service, dynamic network recruitment, ad-hoc / mesh network routing algorithms, heterogeneous networks, cooperative network detection, vertical / horizontal networking services integration. advanced research is conducted on topics such as: 4G network planning * Network resource distribution and task * Error tolerance and availability * 4G Killer Applications * 4G network standardization.

4G Wireless Design Forum

The 4G Design Forum has tried to perform various functions that are considered necessary for 4G Systems, which arose from different potential users during the deliberations. A consensus has been reached by the 4G forum to address

(1) Education, art and science-many consumers appreciated the convenience of being able to achieve a wide range of information without any hindrance to the site. Many had the impression that knowledge and information that correspond to those provided by the school class can be achieved through mobile communication.

(2) Entertainment o Long time consumers wanted the opportunity to watch movies anywhere with their free time. Its "serious nature" (which can enjoy service anytime, anywhere) and "private nature" (realized a wide range of entertainment services on individual terminals) was well-accepted.

(3) Business Consumers evaluated the elimination of the need for large-scale paper information cart.

(4) Visual Communications-oMany recognized the necessity of the service – especially to show videos of themselves to relatives who live far away in real time.

(5) Work-oMany loved the convenience of being able to realize a mobile phone, commuter passport, wallet and keys handled separately today, in a single terminal

(6) Mobile EC -OMANY acknowledged a high valuation of the reason why it is convenient to purchase purchases from mobile terminals and also because of the prospects of creating new business. It looked so striking that some expressed a bad deal to shop too much from a mobile handset.

(7) Daily life -Orgarded as a very useful image. Many wanted this to be realized with sufficient security through retinal authentication etc.

8 Nurses and Healthcare-oMany shared a relief in relief in order to strengthen the health of older relatives from a remote place.

4G wireless platforms.

The reference model on a 4G Wireless platform consists of

· The mobile terminal,

· 4G mobile communication system infrastructure, and

· Service platform.

The mobile terminal.

It implements multi-link communication with the 4G system and other system infrastructures. When a system infrastructure is not available in the communications area, multi-hop communication is performed. The mobile terminal is equipped with various interfaces, for example for electronic paper browsing, among other things, as well as auxiliary functions including voice / image / character recognition. In addition, security, authentication and authorization functions are enhanced with biometric sensors and copyright ID. With the mobile terminal configuration feature, users can download and implement heterogeneous programs or customize their phones. The large number of functional requirements for mobile terminals and connected devices is a clear sign of future mobile terminals.

4G system infrastructure
