If we look back, we will find that every next decade, one generation is advancing
in the field of mobile technology. Starting from the First Generation (1G) in 1980s,
Second Generation (2G) in 1990s, Third Generation (3G) in 2000s, Fourth
Generation (4G) in 2010s, and now Fifth Generation (5G), we are advancing
towards more and more sophisticated and smarter technology.
Whatis5GTechnology?
The 5G technology is expected to provide a new (much wider than the previous
one) frequency bands along with the wider spectral bandwidth per frequency
channel. As of now, the predecessors (generations) mobile technologies have
evidenced substantial increase in peak bitrate. Then — how is 5G different from
the previous one (especially 4G)? The answer is — it is not only the increase in
bitrate made 5G distinct from the 4G, but rather 5G is also advanced in terms of:

 High increased peak bit rate
 Larger data volume per unit area (i.e. high system spectral efficiency)
 High capacity to allow more devices connectivity concurrently and
instantaneously
 Lower battery consumption
 Better connectivity irrespective of the geographic region, in which you are
 Larger number of supporting devices
 Lower cost of infrastructural development
 Higher reliability of the communications.
As researchers say, with the wide range of bandwidth radio channels, it is able to
support the speed up to 10 Gbps, the 5G WiFi technology will offer contiguous and
consistent coverage — “wider area mobility in true sense.”

Architecture of 5G is highly advanced, its network elements and various terminals
are characteristically upgraded to afford a new situation. Likewise, service
providers can implement the advance technology to adopt the value-added
services easily.
However, upgradeability is based upon cognitive radio technology that includes
various significant features such as ability of devices to identify their geographical
location as well as weather, temperature, etc. Cognitive radio technology acts as
a transceiver (beam) that perceptively can catch and respond radio signals in its
operating environment. Further, it promptly distinguishes the changes in its
environment and hence respond accordingly to provide uninterrupted quality
service.

The system comprising of a main user terminal and then a number of independent
and autonomous radio access technologies. Each of the radio technologies is
considered as the IP link for the outside internet world. The IP technology is
designed exclusively to ensure sufficient control data for appropriate routing of IP
packets related to a certain application connections i.e. sessions between client
applications and servers somewhere on the Internet. Moreover, to make
accessible routing of packets should be fixed in accordance with the given policies
of the user (as shown in the image given below).

TheMasterCoreTechnology
As shown in the Figure 5, the 5G MasterCore is convergence point for the other
technologies, which have their own impact on existing wireless network.
Interestingly, its design facilitates MasterCore to get operated into parallel
multimode including all IP network mode and 5G network mode. In this mode (as
shown in the image given below), it controls all network technologies of RAN and
Different Access Networks (DAT). Since, the technology is compatible and

manages all the new deployments (based on 5G), it is more efficient, less
complicated, and more powerful.

Surprisingly, any service mode can be opened under 5G New Deployment Mode
as World Combination Service Mode (WCSM). WCSM is a wonderful feature of this
technology; for example, if a professor writes on the white board in a country – it
can be displayed on another white board in any other part of the world besides
conversation and video. Further, a new services can be easily added through
parallel multimode service.

Normally, it is expected that the time period required for the 5G technology
development and its implementation is about five years more from now (by 2020).
But to becoming usable for the common people in developing countries, it could
be even more.

Disadvantagesof5GTechnology
Though, 5G technology is researched and conceptualized to solve all radio signal
problems and hardship of mobile world, but because of some security reason and
lack of technological advancement in most of the geographic regions, it has
following shortcomings:
 Technology is still under process and research on its viability is going on.
 The speed, this technology is claiming seems difficult to achieve (in future,
it might be) because of the incompetent technological support in most parts
of the world.

5G
14
 Many of the old devices would not be competent to 5G, hence, all of them
need to be replaced with new one — expensive deal.
 Developing infrastructure needs high cost.
 Security and privacy issue yet to be solved.

5G
15
Challenges are the inherent part of the new development; so, like all technologies,
5G has also big challenges to deal with. As we see past i.e. development of radio
technology, we find very fast growth. Starting from 1G to 5G, the journey is
merely of about 40 years old (Considering 1G in 1980s and 5G in 2020s). However,
in this journey, the common challenges that we observed are lack of
infrastructure, research methodology, and cost.
Still, there are dozens of countries using 2G and 3G technologies and don’t know
even about 4G, in such a condition, the most significant questions in everyone’s
mind are —
 How far will 5G be viable?
 Will it be the technology of some of the developed countries or
developing countries will also get benefit of this?
To understand these questions, the challenges of 5G are categorized into the
following two headings:
 Technological Challenges
 Common Challenges
8. CHALLENGES

5G
16
TechnologicalChallenges
 Inter-cell Interference: This is one of the major technological issues that
need to be solved. There is variations in size of traditional macro cells and
concurrent small cells that will lead to interference.
 Efficient Medium Access Control: In a situation, where dense
deployment of access points and user terminals are required, the user
throughput will be low, latency will be high, and hotspots will not be
competent to cellular technology to provide high throughput. It needs to be
researched properly to optimize the technology.
 Traffic Management: In comparison to the traditional human to human
traffic in cellular networks, a great number of Machine to Machine (M2M)
devices in a cell may cause serious system challenges i.e. radio access
network (RAN) challenges, which will cause overload and congestion.
CommonChallenges
 Multiple Services: Unlike other radio signal services, 5G would have a
huge task to offer services to heterogeneous networks, technologies, and
devices operating in different geographic regions. So, the challenge is of
standardization to provide dynamic, universal, user-centric, and data-rich
wireless services to fulfil the high expectation of people.

 Infrastructure: Researchers are facing technological challenges of
standardization and application of 5G services.
 Communication, Navigation, & Sensing: These services largely depend
upon the availability of radio spectrum, through which signals are
transmitted. Though 5G technology has strong computational power to
process the huge volume of data coming from different and distinct sources,
but it needs larger infrastructure support.
 Security and Privacy: This is one of the most important challenges that
5G needs to ensure the protection of personal data. 5G will have to define
the uncertainties related to security threats including trust, privacy,
cybersecurity, which are growing across the globe.
 Legislation of Cyberlaw: Cybercrime and other fraud may also increase
with the high speed and ubiquitous 5G technology. Therefore, legislation of
the Cyberlaw is also an imperative issue, which largely is governmental and
political (national as well as international issue) in nature.

Several researches and discussions are going on across the world among
technologists, researchers, academicians, vendors, operators, and governments
about the innovations, implementation, viability, and security concerns of 5G.
As proposed, loaded with multiple advance features starting from the super high
speed internet service to smooth ubiquitous service, 5G will unlock many of the
problems. However, the question is — in a situation, where the previous
technologies (4G and 3G) are still under process and in many parts yet to be
started; what will be the future of 5G?
5th
generation technology is designed to provide incredible and remarkable data
capabilities, unhindered call volumes, and immeasurable data broadcast within the
latest mobile operating system. Hence, it is more intelligent technology, which will

interconnect the entire world without limits. Likewise, our world would have
universal and uninterrupted access to information, communication, and
entertainment that will open a new dimension to our lives and will change our life
style meaningfully.
Moreover, governments and regulators can use this technology as an opportunity
for the good governance and can create healthier environments, which will
definitely encourage continuing investment in 5G, the next generation technology.
