“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.

4G mobile platforms.

The reference model of a 4G wireless platform consists of

· The mobile terminal

· 4g wireless system infrastructure and

· Services platform.

The mobile terminal.

It takes multi-link communication with the 4G system and other system infrastructure. If a system infrastructure is not available within the range of communications, multi-hop communication test. The mobile terminal is equipped with various interfaces, such as electronic paper, including browsing, and auxiliary functions, including voice / image / character recognition. Ts further security, authentication and authorization functions reinforced with biometric sensors and Copyright IDs. The mobile terminal reconfigurability feature allows users to download and execute heterogeneous programs or their mobile phones to adjust. The large number of functional requirements for mobile devices and the connected devices is an important feature of future mobile devices.

Vocations cards are used by millions of people to make cheap international calls. Decreasing costs for local calls from mobile phones has made it cost to phone to use on your phone. But those savings at the expense of convenience. For most phone cards to make the users in more than 30 songs to choose before the call is connected to the target. It is not possible for the number of cell contacts and select the connection by right. If you have a lot abroad, this discomfort can be very frustrating.

There is hope in sight, mobile phones have become smarter. More precisely, there are some innovative companies, the EZY-dial applications that users can select a series of forms, through their contacts and call through a phone company to have developed, the redirect target. It is used as cost effective as a business card, without the hassle Select PIN numbers and access numbers.

All these days is much on the type of digital wireless communications gadgets already on the big market. It’s really great, and many different styles and colors with a mobile high-tech adaptation of the top brands of GSM phones. GSM phones are designed with a service provider. In theory, all you have to do is change the SIM card into the phone account. But some service providers lock the phones they sell you.

Many ISPs block a phone to their network, so you can not just up and leave them whenever you want. They do this by blocking the phone SIM card to the phone itself, so that no other SIM will work in it. But what if you want to change networks? What if your old contract and a shiny new (and cheaper)-operator, or just to put a local SIM operators to use when you travel abroad?

Phones are naturally unlocked

When originally manufactured, all GSM phones unlocked. That is, they can be used with any SIM card from a mobile phone service provider – always assumed, of course, that the cell phone compatible GSM service provider on the same frequency band, the phone can operate. Most mobile phone service providers electronically ‘lock’ the phone so that they can only be used with their service. There are clear reasons why they choose to do so – especially to pay, allowing you to what is usually very high roaming charges when using your phone from their network and use elsewhere in the world.

Fortunately, this locking is reversible. With some phones it is possible to set a password, enter the unlocking code into the phone and it will be activated immediately after. Phones must be connected to a special unlocking data terminal.

What is GSM? Is it different than regular phone service? How do I know if I have GSM or not?

GSM is a type of digital mobile phone service. The more common form of digital telephony in the U.S. is CDMA, but uses just about every other country in the world, primarily or only GSM. Because you’re a user of the phone there is no difference between using a phone on a CDMA system or a phone on a GSM system. Unfortunately, the two systems are not compatible.

Today mobile phones are made by innovative technologically advanced applications such as GPS or Global Positioning System. Equipped with this remarkable device, cell phones can now operate their basic functions. With the GPS system for mobile phones as a tracking device, that people find the right places or even hunt a family member or friend to be put on the exact location.

GPS or Global Positioning System is a device used to nail down people specific location anywhere on Earth. The central hub of the system depends on “24 satellites” that move around the earth twice a day. The identification of specific locations is possible with fully functional devices, which includes a number of receivers and satellites.
