Introduction to the topic
The principal purpose of this study report revolves around advanced theory related to the
environment of wireless propagation. Wireless communication can be comprehended as the
transmittal of the distance of requisite inputs over allowed distance sans requirement of any
wires, cablesand differrent types of electrical conductors. This widely popular kind of a data
communication, which is carried out and delivered without using any wires, integrates every
process and forms of establishing connection and communication amidst all procedures and
forms of connecting by making use of a wireless signal via wireless communication technologies
and devices [1].Describing coding technologies of different kinds such as Amplitude Shift
Keying (ASK), Phase Shift Keying (PSK) and Frequency Shift Keying (FSK) is what this report
aims. In addition, different kinds of amplitude and angel of modulation methods are included in
wireless communication besides numerous graphical and mathematical representations,
including planning, architecture, and design for large-size WLANs. Wireless Networks and
Communication are primarily required by different cellular systems including multi access and
concerns of interference administration [6]. Throughout this study focus will be on merely
design, evaluation and elementary limits required to address wireless transmission system and
complete capacity of wireless communication mediums, which intends of highlighting multi-user
capacity and corresponding standards.
Introduction to those two papers, their main work
There has been provided an appropriate analysis in the first chosen paper “Wireless Powered
Communication Networks: An Overview” in terms of advanced theory leading to wireless
communication and the propagation environment [3]. This paper inclines in covering a list of
specifications such as installation, operation and performance. Moreover, cellular systems
typically include multi access and concerns associated with interference administration[7]. The
chosen first paper focuses on wireless communication design, analysis and basic concerns
besides providing an idea revolving around the capacity of wireless communication. The paper
also provides an overview on multi-user opportunities for wireless communication. In 1896
when communication was carried out mainly with the help of encoding characters in preferred
3

analog signal, it is then when the technology of wireless communication has come into picture.
The year 1960 saw the launch of communication satellites. Analog and digital voice is perceived
as the first generation global cellular network. Invoice services worked on reasonable data
service rates while two different operations are seen in 3G networks namely UMTS and CDMA
2000 [8].The second chosen paper “Using any Surface to Realize a New Paradigm for Wireless
Communications” provides an overview of different types of encoding methods i.e. ASK, FSK
and PSK besides modulation methods and its full mathematical arrangement [12]. I It also
discusses on a series of reasons behind the choice of encoding techniques. Transmission media
during communication between the devices propagates in type of analog signals where analog
input is observed in electrical pattern that can be cheaply and easily transferred. All requisite
types of voice transmission can grade lines over voice. The paper also provides detailed
discussions of different factors such as SNR (Signal to Noise) ratio, transmission rate of data and
bandwidth [9].
Detail description of the methodologies employed in those two papers
In both chosen papers qualitative research methodology have been used for comprehending the
meanings, describing and understanding experience, ideas, beliefs and values, intangibles such as
these. A kind of scientific research, this methodology used in both the papers comprised of an
analysis seeking answers to a question, systematic use of a predefined set of procedures for
getting the question answered, gathers evidence, produces findings that were not advance
identified; and producing the findings implemented beyond the studies immediate boundaries
[5]. It has been observed that the research methodology used in both the papers have shared these
attributes. In addition to this, it has also helped the respective researchers in bettering
understanding about the research topic from the point of view of people that were involved
during the research. Furthermore, the extensive use of this qqualitative research methodology has
helped both the chosen research papers to obtain specified information about the growing
significance of wireless network and communication in today’s age. The effective use of
qualitative research methodology has helped the researchers in providing complicated text
account on the experience of people on a given research topic besides coming up the info about
the “human” side of the topic – that is usually the conflicting behaviors, beliefs, opinions,
4

emotions, and relations of individuals.A spectrum of methods and tools has been used by the
authors of the chosen papers such as focus groups and in-depth interviews [4] .
Comparison of the results reported in those two papers with each other
In wireless channels, there exists a line of sight perceived being the best is much required, asserts
the first paper selected. One can easily receive this signal by getting it transmitted through
objects and their overall reflection thus, addressing how it is scattered overall. Only at the objects
edges, the emission can be seen. Wireless channel uses reflection for making copies in large
numbers, required for the signal to occur. One can state modulation as a format of signal
requisite to send bits of information[11]. The second selected paper outlines an idea of delta
modulation where steps are entirely assigned to all binary digits. By increasing the overall
sampling rate improvement can be brought in overall precision. There is tremendous rise in the
popularity of digital techniques, which uses repeater over amplifiers [2].
Comments on the advantages/disadvantages/superiority of those two papers
The initial paper provides an outlook focusing on the criteria to encode signal for different
aspects such as SNR proportion, data rate and complete bandwidth. Increasing data rate can give
rise to full rate of bit error while rise in SNR can reduce it, and a bandwidth increase can hike
data rate. The second paper discusses about the added bits needed to handle errors that are
identified principally besides providing an ideas for adaptive modulation and coding for getting
accommodated with the existing channels modulation and coding conditions.
Suggest changes/future-directions for those two papers to improve them (if any).
The author in the first paper intends to provide in-depth info about the elementary frequency,
spectrum, complete bandwidth and effective bandwidth. All frequency elements of a signal are
considered in fundamental frequency to integer the multiples of a certain given frequency.
Establishing relations amidst data rate and its bandwidth are also planned hence any such
5

suggestion for change or future direction is not needed. Author of the second paper has come up
with an idea of adding some digital techniques required to send analog data besides providing the
plan of utilizing repeaters over amplifiers. However, it is suggested some detailed info about
video compression is provided in future research.
Conclusion
From the above report it can be concluded that wireless communication is has increasingly
emerged as a preferred wired networks. It is evident from the study that the popularity of
wireless network communications has tremendously increased owing to its affordability and
adopted by more users. Freedom from place restriction, scalability and flexibility is provided by
wireless networks through popular technologies such as Wi-Fi and cellular networks. It is further
evident from analysing the two selected research papers that the most desired attribute of
wireless networks revolves around its mobility. However, by studying the chosen papers in detail
it has been observed that despite of hoards of benefits, wireless networks is confronted with a
few important concerns with reference to political and technical issues. Wireless communication
is carried out mainly with the help of a given wireless media
