1WIRELESS NETWORKS AND SECURITY
Introduction
Wireless communication technology can be defined as the modern
option to the traditional wired network [3]. All the wired networks
eventually rely on the cables that are utilized for the successful
connection between the digital devices. However, the wireless networks
do not rely on any wire or cables. It is completely free from the wires and
hence termed as wireless in nature. All the wireless technologies are
utilized in house as well as business computers for the purpose of various
utilizations [11]. There are several important advantages of these wireless
technologies. They are responsible for reducing the overall cost of the
networks and thus are used by all. The various types of wireless network
technologies mainly include Bluetooth, wireless fidelity, 3rd generation
communication, 4th generation communication, home automation
standards and many more [5].
The following report will be providing a detailed description on the
wireless networking and its concepts. All the wireless technologies provide
advantages of mobility to the users. This report will be focusing on a
precise comparison between the various wireless technologies and thus
providing all the details related to wireless communication. Moreover, a
proper evaluation will also be done on the standards of wireless
communication for CPS as well as IoT. Proper justification will be provided
on the best technology.

i)
Communi
cation
Spectrum
There are several
communication
spectra in satellite
[7]. There are six
bands in satellite
that are L-band, S-
band, C-band, X-
band, Ku-band and
Ka-band. The
frequency spectra
are 1-2 GHz, 2-4
GHz, 4-8 GHz, 8-12
GHz, 12-18 GHz and
26-40 GHz.
Eight protocols are
present with their
own frequency
spectrum. They
are IEEE 802.11a,
IEEE 802.11b, IEEE
802.11g, IEEE
802.11n, IEEE
802.11ac, IEEE
802.11ad, IEEE
802.11af, and IEEE
802.11ah. the
spectra are 5 GHz,
2.4 GHz, 2.4 GHz,
5 GHz, 6 GHz, 60
GHz, below 1 GHz
and 700 MHz [1].
Two protocols of
WiMax are
present [14]. They
are IEEE 802.16e
and IEEE 802.16d.
Frequencies are
2.3 GHz, 2.5 GHz
and 3.5 GHz in
IEEE 802.16e and
3.5 GHZ and 5.8
GHz for IEEE
802.16d.
ii)
Modulati
on
Techniqu
es
Three techniques
are present. They
are OQPSK or
orthogonal
quadrature phase
shift keying, BPSK
or binary phase key
shifting and QPSK
Quadrature Phase
Shift Keying [12].
The modulation
techniques for the
wireless fidelity
are QPSK or
Quadrature Phase
Shift Keying and
CCK or
complementary
coded keying [3].
The modulation
techniques for the
Worldwide
Interoperability for
Microwave Access
are 16 QAM, 64
QAM 64
quadrature
amplitude
modulation, BPSK
and QPSK.

Protocols for MAC
are TDMA or time
division multiple
access and FDMA or
