One sure about the proper and exact definition the
In today’s globalized world, the progress in information technology Industry has become very strident during last few decades. The significant contribution in this regard is the wireless communication industry. Furthermore by taking advantage of this contribution in field information technology, people have experienced a huge in the usage of wireless devices and mobile services. This usage of wireless devices have increased quickly with enormously scale, the rate of adoption for wireless devices has exceeding 100 % (2009) in the countries like Hong Kong and Italy. However, the development of this industry has witnessed numerous generations like 1G, 2G, 3G and 4G. Among these peers, each of them possesses different criterions, capacities, techniques and unique features that distinguish them from former generations giving birth to an increased number of cell phone subscribers all over the globe day-by-day. In this day and age, the wireless telecommunication industry is growing at a continuous period, customers demanding more and more. Hence, there is a dire need to enhance the communication industry. The wireless communication is the most dynamic and earth-shattering development of the modern era, we are living in.
The idea of this cellular industry was first initiated in AT&T’S bell labs in early 1970’s. This development resulted into the mobile wireless communication industry for the first time in the history. The first commercial mobile which was developed in 1981, was named as Nordic Mobile Telephone (NMT) networks. Formerly, there was the first trial of the mobile communication in 1978 in Chicago, USA. Meanwhile, several parts of the world made progress in this regard most notoriously in Japan and other European countries like Denmark, Finland, Norway and Sweden.
It provides unified, protected and modified delivery of services.
It provides Mobile access that goes beyond various kinds of networks functioning on distinct principles of technology.
Despite the availability of 3G wireless services and their admire ability of functioning, the customers may enquire why they should use or require this 4G service networks? The answer of this question is based on fundamentally two reasons. Firstly, the considerable progress in general number of endorsers. Secondly, the substantial interest of the original information technology services like quality picture, easily accessible audio and video streaming and informative services.
These two gadgets are acceptable to fetch a substantial bottle-neck inside mobile communication industry (Munro, 2007). Although the point that the projected data rate is around 2Mbps in a 3G network, the actual statistics rates are sluggish. Additionally, the information rates equally depend on the customers ‘drive and area not amazingly estimated, the information facilities are working to accept uncertain part as well as these be will astound action instead to voice in future.
Since, every phenomenon has its two perspective side effects; positive and negative, in the same way, being so valuable and so worthwhile to its typical customers, there are different advantages and disadvantages of the 4G wireless network service too. The disadvantages can be listed below:
Security:
It can be categorized as the replacing of the moveable hubs from one point of access to another point in a continuous system or to a varied network. This makes the 4G system to confront with partial difficulties and dangers. Precisely, if a multipurpose user is having this handover process from GPRS to WLAN, it means there is an adequate risk of correspondence that enables the moveable or portable customer miserable and annoying (Varshney, 2012).
Moreover, the[2] 4G wireless network uses different antennae and transmitters which will surely cause customer’s devices a battery problem and in order to avoid this drawback they will need to use devices having larger battery power to remain online on this network. This would certainly, though, force the consumers to use 3G or Wi-Fi networks especially in those areas which do not have such network service or coverage. The most worst and disturbing fact is that they will have to pay the similar amount of money which is determined by 4G networks. This will, certainly, discourage the many users. However, this issue can be resolved, only, if this 4G wireless networks is enlarged to exceptional areas where the service is unavailable.
Faster Speed:
It is another paramount feature of 4G service because its speed is four times higher and faster than its formers generations. Perhaps it is the beauty of this generation. A user can instantly download movies having larges MBs in just few minutes. It provides its users the facility to download different movies, songs, videos, games and other applications, too. The user can access live videos, can chat with friends and family across the globe and can send and receive data as he like it without any restriction or poor service.
Better security:
This is perhaps the most convincing and elegant feature of the 4G generation because it not only provides the security to its users but guarantees the protocol and various security arrangements for consumers. It has most advanced plans for security in wireless service. It’s very robust and consistent network stops information from being leaked or hacked.
The demand of the high speed internet services have got a great boost overall all around the world and this is why telecom sector has been worried about it. 4G wireless technology is very much updated technology and can fulfill the present demands of the internet services. However, there is still a lot of work needs to be done in this field and there has to be something which can create a difference. 4G wireless technology has still got some hidden features which can definitely facilitate the needs of the people.
Consider remote eras as a modest bunch of administrations that get speedier and more component rich as more up to date innovation gets to be accessible. The 3G systems that we utilize today permit us to stream video, download music and documents, and surf the web at normal download speeds from 600Kb/s to 1.4Mb/s. With 4G you'll have the capacity to do likewise yet at much quicker rates, while the additional data transmission opens the entryway for fresher applications. 4G has already created a huge impact on the usage of the internet due to its high speed internet quality. There is still a lot of work required in order to make these services more efficient and reliable for the people.
We have also seen the rapid changes within the technology world in the last few years and we understood that wireless technology has something special to provide people because of its efficiency and high speed. The trend has totally been shifted from wired network services to wireless and people prefer using wireless services because gadgets like mobile, tablets and laptops offer you quick access to all your online data through wireless services. In order to make them use high speed internet, 4G wireless technology must be implemented to provide a better internet experience to the people who actually need such services.
