EECTRONICS Wireless Communication Assignment - University Course

This document presents a solution to a wireless communication assignment, addressing various aspects of the subject. The assignment covers the conversion of binary data to analog waveforms using different modulation techniques, including ASK, FSK, PSK, and QAM. It also involves frequency assignment calculations, waveform drawing for analog and frequency modulation, and the creation of a 16 QAM constellation diagram. Furthermore, the solution explains the error detection process for Cyclic Redundancy Check (CRC) and includes computations for frame check sequences and Direct Sequence Spread Spectrum (DSSS) transmitted signals. The assignment also differentiates between infrastructure and ad hoc modes in WLAN, accompanied by diagrams. The solution compares the differences between TCP and OSI protocols. The document also covers the comparison between square and circle shapes for cellular communication compared to hexagonal cells. References are also provided.

8 Difference between infrastructure and ad hoc models in WLAN
Infrastructure mode is used on wireless devices where by the can connect and communicate or
either can connect with wired network hence they are require an access point for successful
communication. Ad-hoc mode which is also known as peer to peer mode since it’s used by

EECTRONICS 9
people who are familiar to each other. In this mode an access point is not necessary and this
mode is important for cases like network connection on non-existing infrastructures that are
wireless or either their services are not important in that case.
Ad hoc mode
Ad hoc mode in this mode an access point is not necessary and this mode is important for cases
like network connection on non-existing infrastructures that are wireless or either their services
are not important in that case.

9 Difference between TCP and OSI protocols for wireless and wired LANs
TCP OSI
It has four layers It has seven layers
It is still used up to date in computer
networking
It is no longer used
To demonstrate it functionality of the upper
layer it uses one layer
It uses three layers to demonstrate it
functionality of the upper layer
It uses internet layer to show its standard and
routing protocols
It uses network layer to show its standard and
routing protocols
It gives less documentation and explanation
on standard and routing protocols
It gives more details when it comes to less
documentation and explanation on standard
and routing protocols
To demonstrate it functionality of the bottom
layer it use one layer
To demonstrate it functionality of the bottom
layer it use two layers

10 Square and circle shapes for cellular communication compared to hexagonal cells.
Hexagonal cells its distance from the Centre to any point I always the same this cells can be
arranged in a way that help avoid blackspots from being created unlike square or circle they
create spaces that lead to uneven distributed signal across all points. Blackspot are areas that it is
hard to achieve any signal.

EECTRONICS 12
The hexagonal cells are also preferred since it cover the whole area without overlapping.
