Abstract - The eventual goal of the forthcoming 5G wireless
networking is to have relatively fast data speeds, incredibly low latency, substantial rises in base station’s efficiency and major changes in expected Quality of Service (QoS) for customers relative to the existing 4G LTE networks. In order to deal with state-of-the art technologies and connectivity in the form of smart cell phones, internet of things (IoT) devices, autonomous vehicles, virtual reality devices and smart homes connectivity, the broadband data use has risen at a fast rate. Further, to meet the latest applications, the bandwidth of the system needs to be increased widely. This development will be accomplished by using a modern spectrum with higher data levels. In particular, the fifth generation (5G) mobile network seeks to resolve the shortcomings of previous telecommunication technologies and to be a possible primary enabler for future IoT applications. This paper briefly discusses the architecture of 5G, following by the security associated with the 5G network, 5G as an energy efficient network, various types of efficient antennas developed for 5G and state- of-the-art specifications for IoT applications along with their related communication technologies. We have also outlined the broader usage of 5G and its future impacts on our lives.
Furthermore, at the end of each subtopic, the necessary
recommendations are given for the future work.

Introduction :-
The phrase "5g" directs to the fifth generation of wireless
telecommunication technology that will have an epoch- making impact on many facets of life. mobile network traffic continues to grow in a very rapid manner due to new mobile technologies, like; virtual reality applications, high- resolution video streaming and cloud gaming in a few years, the 4g services would certainly not meet the speed of the rise in traffic, as well as the anticipated demands of new scientific technologies, such as unmanned aerial vehicles (uavs), virtual reality and autonomous vehicles. therefore, academia and industrial researchers have made many efforts to make 5g systems a reality in the near future academia and industry have reached a consensus that 5g systems will use rising prominent technologies like network function Virtualization (nfv) and software-defined networking (sdn)
to achieve their goals .
5g is far superior to the current network in terms of transmission speed. 5g will provide data transmission rates of up to 10gbps, which is 10 to 100 times higher than 4g and 4g-lte. 5g is expected to surpass ultra-broadband networks and combine existing technologies such as the internet of things (iot), cloud, big data, artificial
intelligence, and blockchain to support the creation of
innovative services. in addition to improving speed, another significant feature of 5g is its lower latency. as a matter of fact, in the 5g era, the delay time is less than one millisecond
(ms), which is almost equal to the zero data response time in
the real world. in addition, unlike current internet of things (iot) services, 5g is expected to release a huge internet of things. not only that, based on the super bandwidth of 5g per unit area, connectivity per unit, coverage (near to 100 percent) and the ability to connect devices, an ecosystem can be established, where "smart networks" can be used for large medical devices and provide real-time interactivity recently, global companies have taken the lead in the competition for the upcoming 5th-generation (5g) cellular technology, which is thought to be the most important source of revenue in the future the 5g network will be broadly introduced as a simple framework for hyper-
connected mobile devices and will ultimately evolve into a modern 5gaap (5g platform) platform.
Future technology in the 5g environment would create an "intelligent virtual power plant" that will optimize resource usage and incorporate energy use, production and trading. in addition, it is expected that 5g technology will make tremendous changes in the energy industry 5g is a profound network which is expected to solve or shall bring ease in solving the most crucial social problems like; current social problems, such as climate change, disaster safety and traffic congestion, and ignite the awareness of concept of smart virtual power plants in the energy sectors south korea’s 5g technology can be applied to real-time
energy transactions between production and consumption
resources, demand management of factories and buildings, and distributed resource management across the country therefore, it is possible to analyze and predict energy production and consumption patterns using artificial intelligence engines with present real-time big data. the combination of digital twin technology and 5g technology enables system operators to perform optimal operation and
control of virtual power plants through visualized energy
production and energy consumption simulation, there by balancing energy production and energy consumption within virtual power plants. Furthermore, by adopting blockchain technology, real-time secured energy transformation between energy producers and consumers can also be accomplished .

system of 5G.
Use Cases of 5G
:-
In the scope of 5G, three different types of usage cases are
related like :
• Enhanced-Mobile-Broadband (eMBB)
• Massive-Machine-type Connectivity (mMTC)
• Ultra-Reliable and Low-Latency Connectivity (URLLC)
• The eMBB refers to a much or less simple progression of
the improved consumer experience in cell broadband, for example by encouraging still better customer efficiency.
• mMTC refers to facilities that are distinguished by a wide
range of devices, such as remote controls, actuators and tracking of different systems. Main criteria for these systems involve extremely low system expense and relatively low computer energy usage, allowing for a very
long battery life lasting at least a few years. Usually, each
system absorbs and produces only a fairly limited volume of data, i.e. support for large data volumes is of less value. There may be other instances of usage that do not fall perfectly into either of these groups. As an instance, there
could be programs that need massive reliability without
the importance of latency requirements. Similarly, there may be cases of usage involving very low-cost equipment, but where the likelihood of a very long battery life might be less significant.
• URLLC (Ultra-reliable low-latency communication)
Systems for latency reactive tools for applications such as industrial automation, automated driving, and virtual surgery. Such systems need sub-millisecond latency with a response rate smaller than 1 packet loss in 105 packets.
