1.2 Background
Advanced Medicos Limited (AML) is a digital company that is dealing with selling of the health
products , this company has a headquarter office and it is made of two main building s A and B
which hosts the four main departments which includes the Software Development which has a
total of 70 workstations and 10 printers, Production which has a total of 5 workstations and 2
printers, Marketing which has a total of 10 workstations and 4 printers, and Administration
which has a total 5 workstations and 2 printers, these two buildings are 20M apart where the
block A hosts Software Development and Marketing department while block B hosts production
and administration departments, however these departments are not connected through a network
but they only connect to each other through the website, however the both buildings have a local
network that which has only locally connected devices and does not allow the connection of
extra network devices, however the headquarter has the network servers and the router for
internet access.
The management had decided to open a new branch which is located 100M from headquarter
and they propose to install a wide area network to connect it with the head quarter departments.
The management therefore wants to install a new network that will enable connection to all
branches and buildings, allow the wireless internet access, allow addition of new devices into the
network, and enable the workers to work from their homes, allow introduction of new network
devices like computers and printers, enable network future expansion and also to enable the
online selling of the health products to the customers.
1.3 Scope
The proposed network will cover a quite many sections of the network which includes the
following:
i. Connecting the block A building with the new network.
ii. Connecting the block B building with the new network.
iii. Installing wireless network facility for the entire company.
iv. To implement an online website for selling of products.

3 Description & Analysis of Current Setup
3.1 Data Transmission Media
The current network will make use of various types of media to transmit the signals through out
the network; the following are the media to be used.
i. Cat 5e cables.
This is network cable that is used in the connection of the internal network devices and facilitates
their communication it supports a transmission speed of 10MBs and above.
ii. The optic fibre cable.

10Data Communications and Networking
This is the transmission media that is made of thin thread of glass tubes to transmit signals using
the light technology they are proffered to connect the separate buildings and branches.
iii. The wireless router:
This is network device that will be used to transmit the wireless signals to the various user , it
also enable the addition of new devices to the authorised users using the set password and also it
will be used to connect the employees at home.
3.2 Network Hardware

3.3 Logical network(s) topology
The proposed network will mainly be implemented using the two topology which includes the
star and hybrid topology where the star topology will be applicable in the local networks while
the hybrid topology will be used in the entire network, however this topology only indicate the
physical layout of the network devices like the routers and switches and also indicating the
respective ip addresses for the network sections as shown in the figure below.
(Michael, 2017).

3.5 Analysis of existing network
The existing network is bale to support various services which are described in the below
functionalities.
3.5.1 Functionalities
i. The network is enabling the workers in the block A and B to communicate using the
online website.
ii. The network is enabling the internet access through the edge router located in the
block A.
iii. The network is enabling the hosting of website that is accessed by the block A and
block B members to communicate (Paige, 2014).
iv. The network is enabling the printing services to both block A and block B
departments.
4 Conclusions
The current network is having some limitation to the organization, this is because the network is
not fully integrated for the both blocks, therefore below are my findings that justify the
implementation of the new network and elimination of the old network.
