Comparative Study between the 4th and Other Generations of Computers

Abstract

Believe it or not, 4G is coming. Before many of us even have 3G cellular service, the outlook for 4G although still Although the new, third generation (3G) wireless technology has not yet been implemented, leading companies in the industry are already laying the groundwork for what some are calling fourth generation (4G) technology. For this purpose 4G will be as considered those technologies that are still in the planning stages and will not be deployed within the next five years. Researchers are continuing their ideas in the development of an undefined wireless world, which could become operational by 2013. It now appears that the first 4G services could arrive, not between 2010 and 2015 as originally planned, but quite a bit sooner. Parts of 4G, in fact, are taking shape right now. Information is power, nowhere is this truer than on the battlefield, where the ability to communicate clearly and rapidly pass on information spells the difference between survival and death? 4G (4th Generation) is the technology that is going to drive a soldier in the field in future. The key to empowering the military with tactical broadband voice, video and data is 4G communications technology. This technology adopts Wireless technology on the platform of fixed networks, advanced antennae technologies and more advanced wireless security technologies. Next thing is about the gear for the future warrior. Our system provides a enhanced power of vision, which provides Ground Guidance, Unit Detection, Soldier Status, Target Hand-Off and provides the Soldier Rescue during the battle. The uniform along with the armor, onboard computer which will monitor soldiers' overall physiological and psychological picture of how they are performing in the battle zone and enhanced human performance which weighs 50 pounds from head to toe against 120 pounds of the current day system present. This paper discusses about evolution, benefits and limitations of 4G communication technology.
