Information technology is a technology in which both telecommunication computer technologies work together to provide formation. Everyday new technology and inventions are being made in the area of information, processing and travelling.
Transition from 4G to 5G in the mobile industry Essay: It is one of the fastest growing and most dynamic sectors in the world. From the second generation 2G mobile communication system debuted in to the 3G system first launched inthe wireless mobile network has transformed from a pure telephony system to a network that can transport rich multimedia contents.
In 4G systems, an advanced radio interface is used with orthogonal frequency-division multiplexing OFDMmultiple-input multiple-output MIMOand link adaptation technologies. More powerful smart phones and laptops are becoming more popular now a days, demanding advanced multimedia capabilities.
This has resulted in an explosion of wireless mobile devices and services. The EMO pointed out that there has been a 92 percent growth in mobile broadband per year since One of the most crucial challenges is the physical scarcity of radio frequency RF spectra allocated for cellular communications.
Cellular frequencies use ultra-high-frequency bands for cellular phones, normally ranging from several hundred megahertz to several gigahertz. These frequency spectra have been used heavily, making it difficult for operators to acquire more.
Another challenge is that the deployment of advanced wireless technologies comes at the cost of high energy consumption. The increase of energy consumption in wireless communication systems causes an increase of CO2 emission indirectly, which currently is considered as a major threat for the environment.
Moreover, it has been reported by cellular operators that the energy consumption of base stations BSs contributes to over 70 percent of their electricity bill. In fact, energy-efficient communication was not one of the initial requirements in 4G wireless systems, but it came up as an issue at a later stage.
Within five years, the NTT network had been expanded to cover the whole population of Japan and became the first nationwide 1G network. Analog cellular phones are insecure. Anyone with an all band radio receiver can listen in to the conversation. There were thefts in the airtime.
The second generation, 2G system, fielded in the late s. It was planned mainly for voice transmission with digital signal and the speed up to 64kbps. The difference between two succeeding mobile telephone systems, 1G and 2G is that the radio signals that 1G networks use are analog, while 2G networks are digital.
All the operators provide 3G services on the MHz band. The 3G vision is to create a unified global set of standards requirements that could lead to commercial deployment of advanced multimedia wireless communications.
The fourth generation, 4G is a conceptual framework just raised in The speeds of 4G can theoretically be promised up to 1Gbps. A core interface sits in between core network and radio access networks, and a collection of radio interfaces is used for communication between the radio access networks and mobile users.
The beyond will be 5G with incredible transmission speed with no limitation for access and zone size.NEW DATA ON U.S. PRODUCTIVITY GROWTH BY INDUSTRY by Dale W. Jorgenson, Mun Ho, and Jon Samuels1 1 Introduction The computer equipment manufacturing industry comprised only percent of U.S.
