Telecommunications and Networking - Article Example The rise of ICT and electronics brought tremendous advancement to communications technology which had grown from the ordinary Morse code, to simple telephony, and recently through visual telecommunication, and finally to the advent of wireless systems. The impact of this progress hastened the speed and the convenience of delivering and receiving valuable information with vividness and precision. Modern society has become so agile with the fast pace of life, businesses, and the need for mobile technologies has also increased. Developments cope with these needs and telecommunications became mobile with cellular pagers, cellular phones, and recently with mobile videophones. Surely telecommunications is accessible wherever you are in the world. If this technology did exist during WWII, Pearl Harbor tragedy could not have happened. The pace of development along the field of ICT and telecommunication seems so fast that new technologies emerged and changes in monthly basis. Ideas keep coming out every single day and before you know it, what is in today is pass' by the end of the semester. Take for example the emergence of wireless communication technologies. Before we know it the once popular analog mobile phones has gone so far to integrate computing and mobile internet access in just a span of three generations. That is a lot of time if you think of it but to appreciate the progress its better understood in terms of what had changed so far since the first cellular communication device was introduced. We can even trace back our discussion of the history of wireless communications from 0G or Zero generations when telephone systems was still operator assisted with very limited channels. But we have to begin our exploration from First generation (1G) to third generations (3G) of modern mobile communications, a gro wing family of wireless technology. The First Generation (1G) "The big boom in mobile phone service really began with the introduction of analog cellular service called AMPS (Analog Mobile Phone Service)" (Shepler, 2005). The first generation technologies of wireless communications are analog cellular phones. Based on record the 1G era covers the 1980s. The first mobile phone systems, called as "cellular mobile radio telephone" used analog radio signals which are transmitted via a less developed networks of repeaters such as those used by amateur radio operators.. Analog signals are continuous electrical signals that vary in time and variations follow that of the original non-electric signal to make them analogous hence the name analog (Net Tel Information Center, 2004). In analog technologies, the voice signals are transmitted via a base carrier in a form of an alternating current which frequency is changed and varied to match the original signal, amplified, then transmitted via the networks. This system is still used in some landline telephon es and radio broadcasts today. Among the first 1G systems introduced was in 1979, with Japan's Nippon Telegraph and Telephone Corporation, Sweden, Norway, Denmark, and Finland's Nordic Mobile Telephone (MBT) system launched in 1981, and the Total Access Communication System (TACS), deployed in the United Kingdom in 1983 (Britannica Online, 2008). The Second Generation (2G) The birth of digital
