In 1947 it was when researchers looked at crude mobile (car) phones and realized that by using small cells (range of service area) with frequency reuse they could increase the traffic capacity of mobile phones substantially, the basic concept of cellular phones began. However the technology to do so was nonexistent at that time. Motorola marketed the first commercially available cell phone in 1983, the DynaTAC 8000X. The phone cost the company well more than 100 million research dollars. The phone, weighing in at 28 ounces, became instantly popular. The switch from analog technology to digital in 1990 allowed for faster connections and fewer lost or what said as dropped calls.
Many of today's phones feature extra technology, like allowing text messaging, incorporating cameras and providing Internet usage. The field continues to develop new phone features, such as streaming data and video capabilities. Today's phones are known as Third Generation cell phones, which were marketed toward the end of the '90s. New phones require two data rates to operate: Two megabits maximum for indoor use and 384 Kbits for outdoor use.
Stepping up in 2011 now the 4G technology is taking heights, an acronym for Fourth-Generation Communications System, it is a term used to describe the next step in wireless communications. A 4G system will be able to provide a comprehensive IP solution where voice, data and streamed multimedia can be given to users on an "Anytime, Anywhere" basis, and at higher data rates than previous generations.
There is no formal definition for what 4G is; however, there are certain objectives that are projected for 4G. 4G is being developed to accommodate the quality of service (QoS) and rate requirements set by forthcoming applications like wireless broadband access, Multimedia Messaging Service, video chat, mobile TV, High definition TV content, DVB, minimal service like voice and data, and other streaming services for "anytime-anywhere". 4G in principle will allow high-quality smooth video transmission. It will enable fast downloading of full-length songs or music pieces in real time. With mobile phones becoming a necessity, manufacturers are introducing all types of latest phones with never before seen features packed in exceptionally slim and stylish devices, putting the world in your pocket.
No doubt that with advent of such a technology every one of us will be more attracted to have such latest techy models of cell phones, but what always will bother is how to make the best use of old phones then? Well there are organizations who are working towards such purpose. The buyback programmes offered by such organizations gives one the option to choose the model and compare the rates online on their websites and hence sell used cell phones to them in very simple manner.
With the rapid rate of technological obsolescence, these organizations are looking at mountains of e-waste that will only grow taller without effective plans to recycle cell phones. Of course, phone take-back programs will have to expand globally too, and, as UN officials point out, that's a challenge that needs our immediate attention.
