3G internet - Essay ExampleThe world had come a long way from personal letters tight by wax in an envelope. People now live where a conversation with a making love one from continents away is done with scantily a touch of a button.

A few years ago, the GPRS operate seemed alike the future, but it is now perceived as slow, expensive and is too much of a hassle. That is why a new generation of alert knell communication system was developed, the 3G.3G technology is short for terce generation mobile telephone communication system technology. This technology promises reveal, faster and more effic ient entropy transfer through cellular phones. It boasts 2Megabites per second data transfers which each(prenominal)ow video calls, conferencing, mobile banking, map lieu services and internet access among others. With this transfer rate it is the task of the service providers to utilize it to the fullest by adult a variety of services for the subscribers. Along with the above mentioned 3G capable cell phones will still be in possession of conventional voice and messaging services.The institution responsible for standardizing 3G is the International Telecommunication Union or ITU. The standards for 3G are specifically know as the IMT-2000. This stands for International Mobile Telecommunications system finalized in the year 2000. After this establishment, the phylogeny of physical equipments may then proceed.In May of 2001, the first pre-commercial 3G network was launched in Japan brand FOMA.

But with the increase in demand for better audio qualities and later on the demand for faster data transmissions, a better system is require, this soften to the development or 3G.The first step to this change was the switch from 2G to GPRS or General Packet radiocommunication inspection and repair. With this change came the increase in data rates from 56kbps to 114kbps. This now will allow not just voice data but also short message service (SMS), Multimedia Messaging Service (MMS) and wireless application protocol (WAP). Another change made was the per-megabite charging as oppose to the per-minute charging of 2G.Continuing, the GPRS service, otherwise known as 2.5G, was upgraded to 2.75G or Enhanced Data rates for GSM Evolution. By de finition, EDGE falls under IMT-2000 and should be called 3G but it is more frequently referred to as 2.75G, but it is more like an improved GPRS than 3G. (Wikipedia)According to the ITU, the let out characteristics of IMT-2000 are flexibility, affordability, compatibility with existing systems and modular design. It is said to be flexible because it can accommodate five mathematical radio interfaces based on three different technologies which are FDMA, TDMA and CDMA. This avoids the problem of supporting a roomy range of different interfaces and technologies. It is also agreed to make it more affordable so as to assist the adoption by consumers and operators. The existence of the present technologies will also not cease because 3G is also congruous with these. And finally, the 3G system should be easily expandable in order to allow growth.
