“Some men and women see things as they are and say why, I dream things that never were and say why not?” George Bernard Shaw said.
A few years from now the whole world will be wirelessly connected to a series of satellites. Instead of the route of re-tracing the developed countries, developing countries would one of the most modern technologies to store and wirelessly. In the case of poor in the world to gain the power of low-cost wireless technologies such as freephone, their governments and command tools for economic development, such as bank loans, roads, schools and hospitals to speak. Wireless freedom would rise to millions of entrepreneurs, the challenges to overcome to access face the vulnerability of micro-entrepreneur to the larger public market and market information, professional channels to get the world’s consumers are opened. Farmers and fishermen to explore the markets and stretched, where the best price for their products. This will spawn a huge opportunity for the working poor rise from poverty.
Wireless will be in rural areas, the communication is in the rural-urban migration fir through better employment and income in rural areas by small businesses and micro enterprises to improve. Micro-entrepreneurs can turn their phone into the revenue-generating devices to list their product information easily to large online markets, without the need of computers, technological and socio-economic divide created by the “digital divide created by Peter.
It would be so immediate access to legal assistance in civil emergencies and natural disasters, thus saving thousands of lives. Wireless communications arena will have access to health care consulting services in the remotest corners of the world. Telemedicine services, including remote diagnosis and recommend treatment and access to up-to-date market and price information would have become a norm. Wireless communication is largely reduces the opportunity cost of transactions for the farmers and the rural-based traders, it will help education, including distance learning and accountability, the transparency and efficiency of a number of government measures to improve information either in the development of rural areas, making millions ahead in life. The hope is by this way the living standards around the world increase.
4G Wireless
Fourth generation wireless standard is constantly evolving. Once she started going to change how we live our lives. 4G wireless phones would be petite enough to fit into a palm tree and lights in the ground like a pen and the gadget should mention that a phone with data transfer rates of more than 100Mps, a complete surround-sound home theater has to offer, they invite show a full high-definition movie, a micro-projector, the movie on any flat surface, a film he delivers digital effects seem to see a 3D experience.
Any content can be downloaded wirelessly to purify newspapers and magazines to buy. The device can (going fees on the mobile instead of the credit card) for purchases will be used, and it can be used for many other activities where money is needed. Could ask a seller if the card or phone bill. The mobile will be our eyes and ears would be so “intelligent” and “foresight” that not only warn us for the next big sale or the best price for the number one car model, but we also care how shallow the fish was the shooter or warn us in darkness or sneak in the landslide.
These phones for the activities of daily living, such as various household appliances, such as AC, is rice cookers control can be used, etc. refrigerators and used to work with individual functions, depending on user requirements, nursing and health care will change dramatically, physicians can remotely access to routine monitoring of patients in the mobile phones to run in real time and respond immediately to emergencies. A doctor can give first aid guidelines by the sight of the patient on the screen.
Medical data directly to an ambulance or a hospital. A person can scan the mobile he carries are placed. These phones can also be a disaster management by the transmission of real-time data from the disaster areas with people the freedom of time, space and user-defined function. The cost for this mobile and communication skills are so low that the poorest people in the world to rush to the technology because of its apparent benefits clinch.
