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. 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.

The Growing Trend in Used Cell Phones

Cell phones and smartphones are part of the leading edge of technologies that change on a rapid basis. What was new and advanced one year is quickly left in the dust as brand new features and advances grab the attention of the public.

However, not everyone can afford to keep up with the latest trends and many people want a good, reliable cell phone that works for their needs. So, it's little wonder that there is a vast market for used phones that millions of people are purchasing at a fraction of the cost compared to new ones.

There are a number of reasons why you'll find so many people purchasing used devices beyond the fact that they cost less than new ones.

Relevance: Although it may seem that the technology is outdated, the truth is that they can remain operational and relevant for several years assuming that their programming is updated accordingly. Just like computers and laptops can remain relevant with new operating systems so too can cell phones.

Durability: Thanks to the materials used in constructing the outside casing as well as the improved electronics inside, these will last for several years of normal use. This means that used phones can be upgraded and stay functional at a fraction of the cost compared to purchasing a new phone every year.

Carriers: In addition to the traditional carriers, there are a number of new companies that offer low priced services that work well with used devices owners. Companies like ACN, Flash Wireless and FreedomPop offer excellent services for a low price that has attracted many users. FreedomPop for example offers free mobile phone and high speed internet service that has attracted quite a few customers.

As part of the trend with used cell phones, there have been companies that specialize in purchasing and restoring older devices so that they are compatible with new technology. They may not have the speed and all the features, but they are generally quite good and most people may not even notice the difference. This certainly bodes well for the increasing trend of older cell phones as they take up more of the marketplace.

The used cell industry is rapidly growing and is expected to expand at a very high rate in the coming years. This is due to the increase costs and life expectancy of these devices. Many carriers are now providing options for customers to bring their own devices and pay a lower monthly rate which is increasing the market for used devices.
