Demonstrate a broad understanding, knowledge of the principles of networking technologies and the ability to research, analyse and evaluate common network underpinning principles and standards.




Assignment brief

This is an individual assignment designed to allow students to demonstrate a broad understanding, knowledge of the principles of networking technologies and the ability to research, analyse and evaluate common network underpinning principles and standards. It will also assess and evaluate the strength of employee’s analytical abilities. 


You are required to research one of the technologies listed below and produce a report that: educates your fellow workers.

       Li-Fi technology.

       5G Mobile Network

       Ad hoc Networks e.g. Vehicular ad-hoc network

       Body sensor networks / Wireless body sensor networks

       Wireless regional area network (WRAN) 

       Any other topic agreed upon with the tutor

You report should investigate and analyse the underpinning network technologies based on which selected technology is working. Knowing that the underlying technologies are not immune, and hence using these technologies will inherent all vulnerabilities, thus evaluating these technologies is utmost important to evaluate and educate follow students of concern, and potential and future applications. 


You are required to research, analyse, evaluate and identify potential use of this type of data communication, covering the issues related to the underlying networking technology and exploring potential application.




























Introduction / Background

Introduction to the context and/or background to the topic indicating the 6 purpose of the report 

The introduction includes some definitions of complex terminology or 4 acronyms and ideas which link to the conclusion of the report


Knowledge and understanding

Demonstrate an effective approach to studying and research, including explanation and discussion of subject concepts

Demonstrate an effective approach to studying and research, including understanding explanation and discussion of subject concepts

The discussion includes relevant information which is paraphrased / interpretation of credible sources, summarising and accurate understanding of sources.


Applying knowledge and analysis of technologies

Discussion, examination and analysis of underpinning network and

technologies exploring the relationship between different components analysis   

Discussion and analysis of the issues and vulnerabilities including           reasoning based on priori-knowledge, backed by evidence of research from sound sources


Evaluation of underpinning technologies

Demonstrates effective assessment and judgement of the value of information in comparing and evaluating the underpinning technologies with relevant theories

      The discussion supported by literature including critical discussion and evaluation in relation to known issues in the industry such as (but not

limited to) usability, legislation, security, regulation and reflecting on the potential applications of the given technology

Conclusion and/or reflection

A well-defined conclusion / reflection summarising report discussion clearly which is logically presented

An incisive reflection of learning supported by theory where applicable


Presentation and document Structure

The document has an academic style and uses appropriate academic

language, presenting information and discussion using many presentation methods including graphs, texts and diagrams where applicable

The report reflects a level of autonomy and creativity






Assignment Preparation Guidelines

       All components of the assignment (text, diagrams. code etc.) must be submitted in one-word file (handwritten text or hand drawn diagrams are not acceptable), any other accompanied materials such as simulation file, code, etc. should be attached in appendices.

       Standard and commonly used fonts such as Times New Roman, Arial or Calibri should be used, font size must be within the range of 10 to 15 points including the headings, body text and any texts within diagrams,

       Pay attention to the criteria, the report is to be concise and technical. Try to analyse, compare and evaluate rather than simply describe. 

       All figures, screenshots, graphs and tables must be numbered and labelled.

       Material from external sources must be properly referenced and cited within the text using the Harvard referencing system, 

       The report should be logically structured, the core of the report may start by defining the problem / requirements, followed by the proposed solution including a detailed discussion, analysis and evaluation, leading to implementation and testing stage, finally a conclusion and/or personal reflection on learning.

       Screenshots without description / discussion does not constitute understanding and maybe assumed irrelevant.

Li-Fi technology is a networking paradigm that entails the transmission of data through visible light. The term Li-Fi stands for Light-Fidelity, which is a new technological aspect that was proposed by a German physicist by the name of Harold Haas in the year 2011. The Li-Fi technology provides transmission of data through the aspect of illumination. This is achieved by sending data via LED light bulbs, which has a variance in intensity that is faster than the naked human can follow. The Li-Fi technology comes in to replace or work along with the Wi-Fi technology due to its effectiveness and speed of data transmission. Wi-Fi, on the other hand, stands for Wireless Fidelity, which has been an effective technology in general wireless coverage such as in buildings and other certain regions such as parks (Science & Studies, 2015)

Implementation of the Li-Fi technology

A simple Li-Fi based system consists of high brightness LED and a silicon photodiode. The LED acts as the source of communication, while the Silicon photodiode acts as the receiving element.

The data from the sender is converted to the immediate representation of data in byte format, which is then converted into signals of light that are then emitted by the transmitter. The photodiode receives the light signals on the receiver side, and then a reverse process occurs to decode the data back to its original format, which is displayed on the receiving end form of output, maybe a computer or sound system.
