INTRODUCTION TO TELECOMMUNICATION AND NETWORKS
Introduction
The report is presented to discuss the various important aspects of telecommunications
and networks considering the case study of the business organization Cookie Company in
Australia. The company has managed online business activities properly, though it is seen that
due to slow network connection and inappropriate and disturbed voice calls resulting from the
network related issues, there have been misunderstanding between the staffs and customers.
To enhance the experiences of customers and ensure that they are satisfied, it is important to
manage consultation with the technical experts and business partners to improve the existing IT
infrastructure and fulfill the needs and requirements of the business. The networking is a major
component that can not only enhance the customers' services efficiency but will also ensure
that the company manages proper business growth and expansion by enabling proper network
connectivity and maintaining communication between the various departments and staffs at
Cookie Co (Aiello, Merlo and Papaleo 2012).
A. Network infrastructure
A.1 Convergence
Network convergence allows for utilization of telephone, video and data communication
and combines those to create a good network connection. Multiple modes of communication
can be utilized to offer better network flexibility and improve the network infrastructure with
ease and effectiveness. The network convergence, also known as the media convergence can
include sending text messages, explore various websites, manage transmission of voice and
multimedia over the internet protocol networks. This would also enable video conferencing and
manage conversations between the business and customers face to face through the use of
web camera (Bezruk et al. 2012). E-commerce would help in buying and selling of products and
services online by using the internet and ensure that the quality of network services is
improved largely.
Unified communications help in integrating the communication in the business including
messaging, voice over internet protocol, manage audio and video conferencing, enable desktop
sharing along with speech recognition and call control with the non real time communication
services. The unified communication could make Cooke Co. improve the network interface and
even the user experience across multiple devices and media types. It uses various forms of
mobile utility applications and enhances the efficiency of platforms for ensuring proper
communication between the business and its customers with ease and effectiveness (Ims
2012).
A.2 LAN
A local area network or LAN enables connecting a group of computer systems by sharing
a common wireless link such as a router to the server. This can help in managing commercial
business online as well as share resources like a printer or network storage with ease. A LAN
setup includes multiple users who remain interconnected with each other via switches and
routers to connect users to the internal servers. The use of Ethernet and Wi-Fi is essential for

INTRODUCTION TO TELECOMMUNICATION AND NETWORKS
Cookie Co. to manage the LAN connection. One such kind of LAN is the WAN, which can be
installed at the head office to connect all the departments and reduce the level of broadcast
that may span the entire network through the implementation of multiple routers. The network
routers have better functionality than the switches and can manage the network traffic as well
as preserve the bandwidth for various applications (Kermajani and Gomez 2014). Metropolitan
area network could also be used to provide a wider range of network connectivity and use
higher speed technologies at a lesser price when compared to the other WAN technologies.
The LAN is used for enabling network connection by using internet within a lower range
and so it is used at the branches of Cookie Co. The use of Ethernet will help in connecting
multiple computer systems and make sure that network connection is established properly to
manage the business activities online. A cabling plan will consist of various subsystems and
connect the computers systems by using servers, routers, switches, security systems and by
using telecom equipment and phone systems as well (Kuhlenkamp, Klems and Röss 2014). The
backbone cabling can be used at the head office while the horizontal cabling will be used at the
branches. LAN is used by using coaxial cables and even shielded twisted pair is used in the
token ring of Cooke Co. for implementing LAN using Cat3 cable.
A.3 WAN
A wide area network is a telecommunications network that covers a large geographical
area to establish a network by using various telecommunication circuits. The Internet is
considered as WAN and can help in establishing various modes of communication and network
facilities over a long distance. The Asynchronous transfer mode or ATM can make Cookie Co.
manage good data traffic and has been based on the use of internet protocol at the head office
(Mahalingam et al. 2014).
The cable modem is another LAN type that can act as a network bridge to manage
communication of data, information, and messages by using the radio frequency channels
present on the radio frequency and hybrid fiber-coaxial infrastructures. It delivers improved
broadband internet access and can help the company to overcome the low-speed network
connection and even gain benefits of the HFC and RFoG networks. This is suitable and can be
used at the branches (Ostapenko et al. 2013).
A.4 Connecting media and devices
For enabling transmission media, it is important to develop a network by connecting
various people, devices and computer systems. The media types include a copper cable that
includes unshielded twisted pair and coaxial cable, wireless media including radio frequencies,
infrared, microwave and fiber optics. The fiber optics deliver great bandwidth and can prevent
security issues as well as deliver an improved level of security.
A.5 IP and DNS
DNS enables proper communication through the use of internet and uses the computer
systems rather than using the IP addresses. The IPAM integrates both DNS and DHCP to bring
necessary changes in the IP address and improve the functionalities of a network including
better aggregation of data and troubleshooting activities (Ross 2012). The DNS management

could help in reducing the human errors and prevent repetitive and complex data by deploying
those on multiple physical servers. This would enhance the efficiency of the network
connection established and allow Cookie Co. to improve its network stability.
B. Networked services
B.1 Service 1
VoIP – One of the most effective networked services is the voice over internet protocol or VoIP,
which can allow the organization to interact with customers and other businesses by making
calls with the use of broadband internet rather than using any telephonic system. It can save
the cost of using a mobile phone, manages better portability and internet accessibility along
with better flexibility. In case any phone calls come, then the signals can be converted into
digital data and can be routed over the internet (Sansò and Soriano 2012).
B.2 Service 2
Extranet – It is a kind of intranet, which is a controlled private network to allow the business
gain accessibility to its business partners and customers, suppliers and other stakeholders with
ease. It can allow the business organization to transfer or exchange information over the
internet with ease and effectiveness.
B.3 Service 3
Intranet –An intranet is a private and closed network that consists of various LANs
interconnected with each other along with use of leased lines in the WAN. It can create
connections through the use of multiple gateway computer systems to the internet (Sinnreich
and Johnston 2012).
B.4 Service 4
Email – Email or electronic mail allows for transfer or exchange of data, information and
messages from one person to another by use of internet. It is fast, reliable and can even make
the company send its brand-related messages to its customers by emails. This could not only
allow the head and brand offices to remain connected and know about the business operations
but would also create good relationships with the customers (Wang et al. 2013).
C. Data processing facilities
C.1 Data storage
SAN
The storage area network or SAN enables consolidated, block level data storage facilities
by utilising disk arrays, tape libraries and even by managing accessibility to the servers to make
the device for storage act as a locally attached system. The cost and complexity, both have
reduced largely due to utilization in higher numbers across the small and medium sized
organizations.
Cloud storage

6
INTRODUCTION TO TELECOMMUNICATION AND NETWORKS
Cloud storage helps in storing the digital data in pools and the physical storage is
managed by multiple servers that are set up by the organization. The cloud storage facilitates
the accessibility and availability of data and information, thereby keeping the physical
environment protected and functional as well (Wang et al. 2015). Cloud storage offers better
flexibility and ease of storing, accessing and managing data and information with ease and
effectiveness.
Distributed database
The distributed database can be beneficial for the company too for storing various
portions of the database in multiple physical locations while the processing of data is
distributed among multiple nodes of the database.
C.2 Data processing
P2P – The data stored in databases are integrated and used for various purposes afterwards.
The peer to peer data processing could deliver better flexibility, scalability and manage the
corporate network applications and provide best data sharing and exchange services with ease.
This is useful because the customer related data and information are processed and can be
used to assess the needs and requirements if the customers and deliver services accordingly
(Bezruk et al. 2012). Other information and data are processed to ensure that the company
maintains a good brand image and attract as many customers as it can, furthermore improving
the sales revenue and gaining competitive advantage in business for Cookie Co (Ims 2012).
Conclusion
The main focus was done on the business executives who have limited ICT knowledge,
so that they could know how the networking solutions would be beneficial for the business and
improve the customers’ services, therefore ensuring satisfaction of customers and improving
the network infrastructure as well. Various telecommunications and networking technologies
had been used for gaining business benefits and furthermore improve the infrastructure of the
organization effectively. The LAN was used in branch office whereas WAN was used at the head
office. The IP and DNS management was done to prevent human errors and this helped the
company to manage the networked services by using VoIP, intranet, extranet and email. The
storage of company and customer data was managed through the use of Cloud storage and
SAN while the processing of data with the use of P2P had helped in gaining accessibility to
relevant data, use those to improve the business operations’ efficiency and improve the level of
satisfaction of customers.
Recommendations
 Use of firewall is recommended for proving better network security and even protects
the database against any threats.
 The database should be checked properly to prevent any data redundancy
 It is recommended to make sure that the Ethernet cables, coaxial cables, and fiber
optics are arranged properly to keep the flow of network secured and function properly.
