“Some men and women see things as they are and say why,” said George Bernard Shaw.
In a few years, the whole world will be equipped with a wireless connection with several satellites. Instead of retracing the route of developed countries, developing countries would jump to the most advanced technologies and travel wirelessly. In case the world's poor also get the power of cheap wireless technologies, including toll-free numbers, to talk with their governments and command economic development tools, such as bank loans, roads, schools, and hospitals. Wireless freedom will attract millions of entrepreneurs. The problems that microentrepreneurs face in their vulnerability to access to a larger public market, and its market information will be overcome, and profitable channels will open up for access to global consumers. Farmers and fishermen can discover markets and indicate where they can get the best value for their products. This will create a significant opportunity for the poor.
The transition to wireless communication in the rural segment will be that communication will facilitate migration from rural to urban areas, providing better employment and livelihood in rural areas through improved small businesses and micro enterprises. Microentrepreneurs can roll up their revenues into income-generating devices without transferring information about their products to large online markets without using computers, technological and socio-economic gaps created by the “digital divide” will fall.
This will allow instant access to assistance during civil emergencies and natural disasters, thereby saving thousands of lives. Wireless communication will increase access to health extension services in the most remote corners of the world. Telemedicine services, including remote consultations on diagnosis and treatment, as well as expanding access to current market and price information, will become the norm. Wireless communication will greatly reduce the bargaining opportunities for farmers and traders in the countryside, it will promote education services, including distance learning, and improve accountability, transparency and efficiency of a number of government operations through information systems developed in rural areas helping millions in of life. Hope, thereby, will raise the standard of living through the world.
4G Wireless
4th generation wireless standard is evolving. Once introduced, it will change the way we live. 4G wireless mobile phones would be small enough to fit in the palm of your hand and illuminate them like a pen, and the gadget will be different from being a mobile phone with a data transfer rate of more than 100 Mbps, provide full surround sound home theater, download a full movie high definition, there is a micro-projector that could show a film on any flat surface, on it you can see a digital film with effects that provide, apparently, a three-dimensional experience.
Each content can be downloaded wirelessly to buy newspapers and magazines. The device can be used to make purchases (the fee goes to a mobile phone instead of a credit card); and it can be used for many other activities where cash is required. The seller could ask whether to charge the card or mobile phone. The mobile phone would become our ears and eyes and would be so “smart” and “predictable” that it not only warned us about the next big sale or the best price for model number one, but also warns us how outdated the fish are or warn us about that the shooter is in the dark or a landslide in front.
These mobile phones can be used for everyday life, for example, to control various household appliances, such as AC, Rice Cookers, refrigerators, etc., and will also be used to work with customizable functions depending on user requirements, care and health dramatically. change, Doctors will be able to remotely perform routine patient checks from wearable mobile phones in real-time or immediately respond in case of an emergency. The doctor can give first aid directives by seeing the patient on the screen.
Medical data can be instantly transferred to the ambulance or hospital. A person can be placed exactly from the mobile, which he carries. These mobile phones can also be used in disaster management, allowing you to transmit real-time data about the affected areas, giving people freedom from time, space, and user functions. The cost of this mobile and its communication skills will be so low that the poorest people in the world will rush to the clinch technology because of the advantages of its appearance.
4G Wireless Research.
Research on 4G Wireless has continued over the past few years. These networks promise much higher overall data throughput and much more diverse services than what the current second and third (2G-3G) networks can do. All-IP wireless has become the most popular platform for 4G wireless networks. In terms of the future wireless network architecture, consider the fact that the greatest load on 4G wireless networks will be high-speed, rich content, packet traffic, which previously represented a serious problem for all existing wireless networks.
Technologies used in existing networks. Many research projects study the design of compatible architectures for 4G wireless networks, which are experienced, adaptive, flexible and scalable, which work harmoniously with various network technologies (including legacy 2G, 2.5G and 3G networks) and allow the use of heterogeneous network applications. Research is focused on how to implement smooth migration and seamless interoperability between older networks and future 4G wireless networks.
4G architecture.
It was recommended that the 4G wireless network architecture should effectively address all the limitations and difficulties existing in modern wireless network technologies. Research on next-generation wireless networks includes many advanced research topics such as interconnect design of connection optimization, quality of service, dynamic network resource allocation, ad hoc / mesh routing algorithms, heterogeneous network, co-discovery network, vertical / horizontal integration of network services. Modern research is conducted on topics such as: 4G network planning * Distribution and assignment of network resources * Fault tolerance and service availability * 4G Killer applications * 4G network standardization.
Forum on the construction, repair and interior design
The 4G Design Forum attempted to implement various functions that are deemed necessary for 4G systems, which are raised by various potential users during discussions. Congress has been reached on the 4G forum to address
(1) Education, art and science. Many consumers appreciated the convenience of obtaining a wide range of information devoid of any location restrictions. Many had the impression that knowledge and information equivalent to the knowledge provided by school classes could be achieved through mobile communications.
(2) Entertainment. A large number of consumers wanted to be able to watch movies anywhere using their free time. His “omnipresent nature” (the ability to use the services anytime and anywhere) and “private” (implementation of a wide range of entertainment services at individual terminals) were well received.
(3) Business-Consumers appreciated the elimination of the need for a cart around bulky paper information.
(4) Visual communications — many have recognized the need for service — especially in order to show videos to relatives themselves living far away in real time.
(5) Work-oMany took care to be able to realize a mobile phone, a commuter pass, a wallet and keys, which are currently processed separately, in one terminal
(6) Mobile EC-OMANY acknowledged the high valuation due to the convenience of making purchases from mobile terminals, as well as the prospect of creating a new business. It was so striking that some expressed concerns about too many purchases from a mobile phone.
(7) Daily life - Appeals as a very convenient way of use. Many wanted it to be implemented with a sufficient level of security using retinal authentication, etc.
8 Care and health care. Many of them shared common sense in order to be able to confirm the state of health of elderly relatives from a remote place.
(9) Emergency medical care - many considered it necessary to be able to immediately provide the condition of the site and the condition of the victim in the event of an emergency or access to medical information.
(10) Use in case of natural disasters. Many considered it necessary to be able to make contacts to confirm the safety of others and to receive information about the evacuation routes in case of a disaster.
4G Wireless platforms.
The reference model of the 4G wireless platform consists of
· Mobile terminal,
· 4G mobile infrastructure and
· Service platform.
Mobile terminal.
It implements multi-channel communication with the 4G system and other system infrastructures. When the system infrastructure is unavailable within reach of communication, multipoint communication is performed. The mobile terminal is equipped with various interfaces, for example, for viewing electronic documents, among others, as well as auxiliary functions, including voice / image / character recognition. In addition, the security, authentication, and authorization features of ts are enhanced with biometric sensors and copyright identifiers. Using the reconfiguration of the mobile terminal, users can download and execute heterogeneous programs or customize their phones. A large number of functional requirements for mobile terminals and connected devices is a hallmark of future mobile terminals.
4G system infrastructure
The 4G system infrastructure implements high-speed, high-capacity transmission and high-quality multimedia transmission. The system also has the function of notifying QoS between layers to coordinate QoS between levels. Model areas for the vision of future systems are: service and application, service platform based on the packet-based network, new radio access, mobile support, new mobile access, new economic wireless access (NWA), and support for the relationship between New radio access, 2G / 3G cellular systems, WLAN, digital broadcasting, dedicated short-range communications (DSRC), etc. And may be able to configure ad-hoc networks through terminals
Service platform
It consists of many servers and agents. The provided navigation function, based on information positioning systems, controls user credentials and manages / matches personal information through biometric authentication. The service platform is associated with distributed database systems or high-quality content servers, for managing access permissions using authentication servers and providing video or music content addressed to users; preferences or terminal from content servers using an agent. It is also linked to social protection and disaster prevention systems. In the event of a disaster, an extremely stable network is configured to make available multicast communication. There will also be implemented an automatic transmission of an emergency condition associated with the biometric sensors of the terminals.
Various other studies are also facilitated, including improvements to reference models developed for the service platform and system infrastructure, to promote the development of 4G mobile systems and to fulfill the ambitions of being free and mobile in the next age of communication systems.
Conclusion.
World In the course of research on 4G mobile communications (fourth generation), the technology will be introduced worldwide in 2010.
