References & Sources of Information - Range of academic and current business and management references - Citing and referencing sources. A wide range of good quality academic sources have been used, including academic journal articles, books, trade publications, websites, company sources, and reputable data Referencing and citations are accurate throughout. Some good quality sources of information have been used, including at least one academic paper from a reputable journal. The student has clearly not just relied on what they can find on the Internet. References have been drawn from some good quality sources (reputable websites, books, newspapers) but there are no references from academic journals. There are some referencing / citing errors. Only poor quality (e.g. Wikipedia or similar) or no references have been included.

Presentation of report English – Style, spelling, grammar graphs, tables, Literate and appropriate to content. Excellent use of tables and figures for illustrations * Enjoyable to read and of publishable standard Generally correct, but some minor grammar / spelling errors. Good use of tables and figures for illustrations A number of spelling / grammar errors – obvious reliance on automatic spell checker. Limited use of tables and figures for illustrations Difficult to read, with some incoherent sentences. Many errors. No tables or figures.

Analysis of research using lab work Understanding of actual operating conditions and practical performance analysis A clear understanding of the purpose of the lab work and how it can be used to buttress research findings with respect to performance analysis. Correct conclusions are drawn. *The level of understanding beyond expectations. Good understanding of research and lab work. Some attempts have been made to use published works in analysis of lab tasks. Satisfactory understanding of wireless communications performance analysis. Limited reference to published work to support what is written. Lack of understanding of the relevance of network performance measures. Lack of support with published materials.

Range of technologies covered Quantity and quality of background research, analysis of key information, number of wireless technologies covered in report All key topics have been included, with meaningful analysis of each in the context of the assignment. Correct analysis and comparison of at least 3 different wireless technologies * The module topics have been included in an integrated way, rather than just different sections. All of the key topics have been included, with thorough analysis for most. Correct analysis and comparison of at least 2 different wireless technologies Most of the key topics have been included, but the analysis for some may be incomplete or superficial. Limited analysis and comparison of about 2 wireless technologies Many of the key topics may not be included or the paper is written in such a way that it is not clear which module topics are included. Only one technology mentioned and no form of comparison

Class/grade Assessment criteria Distinction (Excellent) Commendation (Very Good) Pass (Good) Fail (insufficient) Grade/ Comment *Exceptional Distinction High C Mid C Low C High P Mid P Low P Marginal fail Mid Fail Low Fail High D Mid D Low D Abstract and Introduction General overview and understanding of wireless technologies Clear and fact based introduction to the investigation, knowledge of area of application and current technical challenges experienced with use of technology. Research gaps The introduction clearly describes the investigation, good knowledge of area of application and current technical challenges experienced with use of technology. Enough information about the investigation. Some knowledge of wireless technologies and applications. It is not clear about the rationale for the investigation, poor understanding of wireless communications.

A summary of key points: ? This is an individual assignment ? Need to submit a Technical report ? An electronic copy of the report (in WORD document) must be uploaded to the module dropbox in NOW not later than 4pm 3rd 8.

As an engineer, you are required to submit a well-structured technical report detailing the process and outcomes of the above research. The good practice of citations and referencing must be evident throughout the report. The Harvard referencing system should be used. The marking scheme: ? In this course work you need to answer all the questions precisely. They have more or less the same mark weightage. ? Each question has 15% of the total 100% mark. ? 10% of the mark will be given to presentation, clarity, writing style, consistency in format particularly for the list of references. ? Mark will be deducted for over-size (more than 13 pages; 12 pages for the content and 1 covering page) submissions. ? Mark will be deducted for late submissions accordingly. Zero mark will be given to those submitted more than 3 days after the deadline.

Students are expected to show knowledge of underlying principles of wireless communication while demonstrating the ability to undertake research and critically analyse information. They are also to demonstrate ability to use results from practical experiments/lab work in buttressing research findings. Wireless technologies are used in different industrial, private and public sectors and are also certified mainly by the IEEE standards. Students are expected to demonstrate knowledge of these standards and the report should include industries or sectors where chosen wireless technologies are predominantly used, analysis of difference between advertised performance and practical operating conditions.

The assignment is designed to provide an opportunity for students to engage in reflective learning through a process of research and peer interaction, while allowing individuals to demonstrate their level of knowledge and understanding in the subject area. Students are expected to demonstrate a good understanding of the key topics associated with the assignment. The report should include evidence of background research and critical appraisal of relevant articles and case studies. Attempts should be made to gather information from a range of sources (book, journals, magazines, newspaper articles, internet etc) with proper acknowledgement.

Citing and Referencing You may need to carry out independent research into the technologies you are analysing. You can use sources which are noted in the module content/module recommended textbook, but you should not use exactly the same data. If references are included in your work – including information sourced from the Internet - you must cite them appropriately in your work

SUBMISSION REQUIREMENTS: Reports: Use font 11pt Calibri, written on one side of A4 only, single spacing. Harvard referencing system must be used. Page limit: Strictly 12 sides maximum (in total including figures and references). You may add a covering page for information about your name, student number, module name, etc.
