The Evolution Of Mobile Communication

Ans. The 3G UMTS systems have two logical entities – the Node-B (the radio base station) and the Radio Network Controller (RNC) while the 4G LTE systems have only one logical node – the evolved Node-B (eNode-B).

When Cellular phones first came out the main use was to make phone calls. The first generation of the cell phone transmitted information the same analog format as a fixed line. The second generation (2G) transmission switched to digital which gave cell phones the ability to

5G (5th generation wireless systems or 5th generation mobile networks) denotes the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G itself is a revolution, with speeds beyond what the current 4G has to offer.

Fifth Generation (5G): 5G Technology stands for 5th Generation Mobile technology. 5G mobile technology has changed the means to use cell phones within very high bandwidth. User never experienced ever before such a high value technology.

In December 1971, AT&T submitted a proposal for cellular service to the Federal Communications Commission (FCC). After years of hearings, the FCC approved the proposal in 1982 forAdvanced Mobile Phone System (AMPS) and allocated frequencies in the 824–894 MHz band.[6] Analog AMPS was eventually superseded by Digital AMPS in 1990.

Over a decade ago the house phone was such a remarkable advancement where it provided a person to call places over thousands of miles away. Then the ease and comfort of wireless phones came out. Now, the invention of cellular phones (a mobile telephone) is an excellent device to do business or call out for help when you need to. While for others it is a failure, annoying and a cause of accidents. “Today, cellular phones have become a necessity in a person’s pocket.”(VanLaecken, H.). In According to the site (http://www.infoplease.com/ipa/A0108074.html), the last survey that was completed contained one million owners in 1999 of cellular telephones. A

As attached to our phones we are its hard to imagine how young the technology of smartphones really are. In 1908 the first apparent wireless device came when Prof. Albert Jahnke and the Oakland Transcontinental Aerial Telephone and Power Company believed they had industrialized a wireless telephone. Sadly they were accused of fraud. Later the charge was dropped and production of the device never proceeded. In 1918, German railroad systems started to test their own wireless phones on their military trains. Trials began in 1924 and a year later Zugtelephonie A.G. was established to supply train telephony equipment with the first telephone systems being accepted for use in postal and other trains by 1926. On June 17, 1946 the first truly mobile phone service appeared on June 17, 1946 under Bell Labs, which industrialized mobile phones that endorsed users to place and receive phone calls from their automobiles.

During this period cellular or mobile communications has begun to rapidly grow. The amount of time spent on network allocation, concentration, usage, and maintenance for these newer technologies were starting to become more complicated.

With the introduction of first generation technology came the existence of Nokia’s Mobira Senator. It was very big and bulky, weighing an incredible 22 pounds. It was not a very mobile phone, but it was a large milestone considering its use of 1G technology. The buyable version of Motorola’s DynaTAC also used 1G technology, specifically North America’s first by Ameritech.

A look back in the history, the first generation of telephony (1G) started in the early of 1980s. This network was designed to carry analog voice data. The (1G) networks were based on these standard TACS, NMT, C-Nets and AMPS. In the early of 1990s the (2G) networks came as a digital network comparing to the analog in (1G). That was the first digital cellular network after the switches that were supported digital calls by using actual 0s and 1s. The (2G) networks were supported by these standards D-AMPS, Code Division Multiple Access One (CDMAOne) and Global System of Mobile Communication (GSM). The second generation of telephony (2G) was offered a higher capacity, improved security and improved the voice quality. The (2G) technology was offered a

From 1G (First Generation) to 3G (Third Generation) the way of mobile communication has changed drastically. The new generation is giving users a new way to communicate and access the services on the go. The ultimate aim of the latest generations is to provide better services to its users.

International Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications defined by the International Telecommunication Union, which includes GSM EDGE, UMTS, and

As a telecommunication engineering student I studied and came to know that there are two basic technologies in mobile phones on which our wireless network is based on. These are: CDMA (Code Division Multiple Access ) and GSM (Global System for Mobile Communications).

Today, the area which are growing and expanding the fastest in global telecommunications is mobile data. In order for us to keep up with the demand, we will have to be active in innovating new products to shape communications that will enhance the lives of our consumers and empower their businesses into the future.
