Article: Cellular architecture and key technologies for 5G wireless communication
networks
Introduction
The prime determination of the paper will be focusing on the importance of the effective
use of the ICT in the form of the wireless networking technologies. The extensive developments
in the field of IT has led to the growth of many new technologies which are used in our daily life.
The researcher of the paper focused on the promising technologies integrated with the upcoming
5G are cognitive radio, massive MIMO and visible light communications.
Critique the methods
The researcher of this paper used reliable secondary resources for reviewing the emerging
technologies used in the 5th generation wireless technology. However, it can also be said that the
chosen method is not very much effective as it did not consider any of the primary resource.
Thus, it can be said that this peer reviewed article will be helping the readers of this paper to
understand the application of the different types of technologies such as the cognitive radio
network in the 5th generation wireless technologies [5]. The findings and the statements of this
paper was reviewed by the Wireless World Research Forum (WWRF) which serves around more
than 7 trillion people all over the world.
Findings of the paper
As stated by Wang et al. (2014), the paper introduces all the emerging technologies used
in the development unit of the 5G wireless technology. The researcher mainly focussed on the
evolution of the wireless technologies. The paper states the issues and challenges of the previous
generations of the wireless technologies. Different concepts such as Multiple Input Multiple

Output (MIMO) and Long Term Evolution (LTE), Radio Frequency (RF) and the Energy
consumptions of the Base Stations (BS) are incorporated in the paper. The researcher of this
paper focussed on the limitations of the 4th generation wireless technology which is the leading
communication networking platform in the world [4]. The researcher presents the cellular
architecture of the upcoming wireless networking technology, followed by this unit the
researcher highlighted the importance of the promising technologies incorporated in the 5G such
as the MIMO systems both at transmission and receiving level. The implementation of the
MIMO technique with the application of the Spatial modulation is stated by the researcher. The
researcher also focussed on the use of the radio cognitive software for improving the use of the
RF [6]. The different aspects of the CR network are used in the paper which is helpful to
understand the utilization of the resources by the licensed users.
According to Wang et al. (2014), visible light communication is very much important for
the LED’s and the SSL. The researchers found out that the use of the signal transmitters is very
much important for the Intensity Modulation and the direct detection. The researcher focussed on
the increase in spectral efficiency with the help of the primary receivers used by the tele
communication industries [7]. The researcher found out that there are different types of
transmission techniques considered in the spectral efficiency and the Mobile Femtocell.
The researcher considered various types of secondary resources to write this paper. They
critically reviewed the findings of the secondary resources before stating those facts in this
paper. The findings the researchers got from the other secondary resources was critically
examined by them to find their effectiveness [3]. The researcher of this paper focussed on the
importance of this paper which can be used for the future researches.

The researchers of the paper found that the stated emerging concepts and technologies
will be playing a huge role when the generation wireless networking technology will be used by
the public.
Opinion about the paper
The paper helps in identifying the complexities associated with the upcoming wireless
networking technologies such as the issues associated with signal processing which is major
problem in this networking system [2]. The paper also helps in understanding the implementation
of concepts such as the massive MIMO, visible light communications and the cognitive radio
networks. The challenges associated with these concepts are also stated in the paper which helps
in understanding the different aspects of the wireless communications [9]. The paper is very
much effective to understand why the existing wireless technologies have so much of issues and
complications which are needed to be considered while developing the upcoming 5G network.
Effectiveness of the paper
The paper is very much valuable to understand the challenges of the existing wireless
networking technologies. The paper provided in-depth knowledge about the different emerging
technologies which are being incorporated into the next wireless networking system [1]. The
researcher focussed on the importance of the emerging technologies in their paper. The paper
also helps in identifying the ever changing needs and requirements of the consumers of the
wireless networking technologies. The most important aspect of the paper is that it provides
information about the cellular architecture [10]. The paper is very much important to understand
how the challenges of the emerging technology may hamper the growth and development of the

wireless networking technologies. The paper is very much helpful to understand how internet
speed is different in each of the generations of the wireless networking technologies.
Future prospects of the paper
Future challenges and the potential of the existing networking technology in the field of
communication is evaluated in the paper. The researcher presented the future challenges of the
5th generation wireless technology in terms of the performance metrics, interference and the
channel models will be useful to review the 5G once it is available in the market. Knowledge
about the emerging technology will be more clear after going through the paper.
Conclusion
The paper helps in concluding that there are lots of emerging technologies which are
integrated in the development of the next generation wireless technology. The issues and
challenges of the technologies are also stated by the researcher which helps in understanding the
issues related to the interference of the CR and the primary system, effective management is
required to resolve this issue as stated by the author. It can be also concluded that the Mobile
Femtocell is very much needed to improve the spectral efficiency.
