At present the need for technology, be it information technology and telecommunications is very high from the beginning and middle class and middle class and above. All individuals in dire need of technology to accelerate the development or increase the development of both individuals and kelompok.Perkembangan development of technology that is currently very quickly is a telecommunications technology, which presents a wide selection of forms of technology and sophistication. When this happens the intense competition between the two technologies of mobile communications and FWA (Fixed Wireless Access). The development of communication technology, especially cellular technology has started since the mid 90's and brought the technology 1G (First Generation) by using technologies AMPS (Advanced Mobile Phone System). Where AMPS technology is first used by the military in the United States.
In the past 10 years since the birth of AMPS suda development occurred very rapidly with a variety of inventions or innovations communication technology and, in the late 90's technology came the 2G (Second Generation). The main difference from the technology g1 G1 and G2 are still using analog systems while the G2 has been using digital systems. 2G technologies can be divided into two major groups, namely TDMA (time division multiple access) and CDMA (code division multiple access). TDMA itself evolved into several versions, namely the European GSM, IDEN in America, PDC in Japan. While CDMA is growing rapidly in the U.S. and Canada. Striking is the 2G technology capabilities not only be used for telephone, (voice) but also to send SMS (Short Message Service) is sending a short message by using text.Dengan the presence of second-generation technology, then came the new-mobile telnologi ie, GSM ( Global System for Mobile communications) A 2G wireless communication system. Frequencies that can be used in GSM are 850MHz, 900MHz, 1800MHz and 1900MHz. A second-generation cellular mempebaharui first generation in the field of digital technology, which in theory is basically a pembaharukan in the field of data transfer, for example, is a GSM (using protocols CSD, HSCSD, GPRS and EDGE) and cdmaOne.Dengan existence of this second generation technology makes the development of technology sooner by presenting a share of excess / features offered by this second generation technology in addition to sending SMS and voice. But all this excess is still not satisfactory experts to develop better technology with all the benefits of technology dri previous (first and second generation).
Then came the early 2000's technology generation 2.5 (2.5 G) which has the ability to transfer data faster. Famous of this generation is the GPRS (General Packet Radio Service) and EDGE (Enhanced Data rates for GSM Evolution) A protocol that governs the workings of data transfer in GSM wireless systems. In theory EDGE data transfer speeds can reach 384 Kbps. 2G technologies are significant improvements, so comes the variants, the 2.5G and 2.75G. This variant is not made by the consortium, but as a marketing strategy by several mobile phone manufacturers. Characteristic of 2.5G technology (generation two and a half) is the technology of GPRS (global package radio service) that can be used to send large amounts of data, unlike SMS which can only send and receive alpha numeric only. 2.5G generation there is also a call with 2.75G generation, because it is closer to 3G technology. Technology 2.5G (or 2.75G), in the GSM system are called system EDGE (Enhanced Data rates for GSM Evolution) is the CDMA system called CDMA 2000 1x. Both have data transfer rates approaching 144KB/detik. The evolution and development of communication technology does not stop here, great countries in the world be it Europe, Asia & America are competing to develop innovation and research to deliver cutting edge technology. Once the technology Generation First, Second and 2.5 G technology, then followed later by the Third Generation (3G) that offers a better advantage again both in terms of capabilities and features of Data Transfer Data transfer with a speed faster than ever in delivering services that are very required by the customer.
now, we will wait what the newest technology will come to our live???
