4G Mobile Technologies Demystified

Until recently, we have witnessed the evolution of mobile technologies from the radio frequency technologies right up to the 3G technologies that are currently making waves all around the world. A new technology has now come to us, 4G mobile technology. This technology is nothing but a new technology for the next generation of mobile phones. It was made available commercially in the USA from the year 2009. But, in India it is a relatively new wave that has not yet reached a crescendo. In India, right now we are in the midst of the 3G wave of mobile technology.

To simplify matters, 4G refers to the fourth generation of mobile technologies. We have got to this stage due to the evolution of technology from its primitive 1G version, through to 4G technology. In other words, 3G mobile technology covers the carrying of data in its digital formats. This activity leads to enhanced information services like websites in their original formats, etc.. The famous Apple iPhone is a silent testimony to the success of 3G mobile technology Igtok. Although we have not reached there yet, the 4G mobile technologies are the next wave of improvisation in mobile technology.

This technology has not yet established itself, and it does not have any agreed set of standards and rules, not to talk of protocols. However, it is sure to revolutionize the way people use the internet on their mobile phones. This technology is not yet fully defined, and so it cannot be said to be totally discovered. This new technology involves enhanced security features since data transfer is increasingly being done through fiber optic cable networks, wireless networks, etc.. 4G technology talks of the security measures to be provided by these enigmatic technologies.

One of the primary goals of 4G mobile technology is to minimize the blips in transmission when devices are taken from one area to another. Another goal of this new technology is to leverage the power of IP networks for increased safety and security of the data that is being transferred through a fibre optic cable network. If 3G made e-commerce a reality, then 4G will make uninterrupted internet access a reality for all and sundry. The USA uses 4G technologies in two ways- WiMAX technology, and the other is Long Term Evolution or LTE technology.

4G technology is primarily used for data and voice transfer over the internet and fibre optic cable networks. Customers who have a strong 4G network in their homes can use it to access high-speed internet access through Wi-Fi networks that are built into routers and switches. This facility does not need the use of cables for data and voice transfer. Unobstructed Internet access, through external networks apart from those being offered by coffee shops, airports and libraries will be made a reality, thanks to the advent of 4G networks.

A teacher’s role is critical in making good decisions regarding the use of technology in order to achieve potential benefits. Choosing the correct software is quite similar to choosing the perfect set of books for a classroom. Teachers should take the advantage of computers to introduce new teaching and development strategies. Computers are intrinsically compelling for young children. The sound and graphics attract a child’s attention. An appropriate software engages children in creative play, mastery learning, problem solving, and conversation. Children control the pacing and the action. They can repeat a process or activity as often as they like and experiment with variations. They can collaborate in making decisions and share their discoveries and creations. Well-designed early childhood software grows in dimension with the child, enabling her to find new challenges as she becomes more proficient. Appropriate visual and verbal prompts designed in the software expand play themes and opportunities while leaving the child in control. Vast collections of images, sounds, and information of all kinds are placed at the child’s disposal. Software can be made age appropriate even for children as young as three or four. This shows that technology can enhance a child’s cognitive and social abilities. It provides a window to a child’s thinking.

Every classroom has its own guiding philosophies, values, themes and activities. Early childhood educators should promote equitable access to technology for all children and their families. Modern technologies are very powerful as they rely on one of the most powerful biases we have. The problem with this is that many of the modern technologies are very passive. Because of this they do not provide children with the quality and quantity of crucial emotional, social, cognitive, or physical experiences they require when they are young.

Unfortunately, technology is often used to replace social situations but it should be used to enhance human interactions. During the current decade, research has moved beyond simple questions about technology. Very young children are showing comfort and confidence in handling computers. They can turn them on, follow pictorial directions, and use situational and visual cues to understand and reason about their activity. Typing on the keyboard does not seem to cause them any trouble; in fact, it seems to be a source of pride. Thanks to recent technological developments, even children with physical and emotional disabilities can use the computer with ease. Besides enhancing their mobility and sense of control, computers can help improve self-esteem.

Thus the exclusive value of technology is no more in question. Research shows that what is solid for children is not merely what is physical but what is meaningful. Computer representations are often more manageable, flexible, and extensible. To add more there are a number of specialized programs that allow children with certain information-processing problems to get a multimedia presentation of content so that they can better understand and process the material. Even now there are a number of good software programs with a primary educational focus on mathematics or reading. These programs, which are very engaging, motivate children to read better and learn how to solve math problems. When information is presented in a fun and way, it is a lot easier than looking at a single page that has a bunch of columns of numbers you’re supposed to add up.
