Student reviews

I do not feel the course description adequately portrays the challenge and difficulty in this module. This module makes use of a lot of mathematical formulae, such as Shannon's law and equations to calculate Doppler shift.

The first module and third module are quite heavy on the formulae and maths side of things. In fact as memory serves the text for module one begins "this module expects you to already have an understanding of basic electrical principles..." Or words to that effect. Don't be fooled by the course description, you will need to do a lot of calculations and remember a lot of formulae.

The exam is the toughest I did in my whole degree.

This was an incredibly tough but rewarding module. For those doing this as part of a computing or ICT degree I would only recommend this module to someone from a Telecoms or networking or electrical engineering background. If you come from other areas (such as software development or web design) you may find this course very hard going (but still do-able).

If in doubt I would urge you to purchase a past paper from the OUSA to let you see what you are letting yourself in for.

Faculty response

Thank you for your comments. I am pleased that you found it rewarding, but sorry that you thought it was difficult and that you feel the course description does not adequately portray the challenge and difficulty of the module. We will look again at the description to see whether we can improve it. There are a lot of calculations in Blocks 1 and 3 as you say, which is why the module description says you need basic mathematical skills so that you can work with algebraic equations and carry out numerical calculations.

A background in telecoms, networking or electrical engineering would certainly help, but students who have studied relevant modules at OU levels 1 and 2 in the OU Computing and IT programme, including maths at level 1 and module T215 (Communication and information technologies) at level 2, should be adequately prepared.

Overall this module is very interesting and varied.

Block one on enabling technologies goes through a variety of technologies from batteries to fuel cells, to LCD screens to Audio coding. I found this relatively easy and the TMA for this was long and required a lot of effort.

Block two was on Intellectual propery and covered issues such as copyright, trade marks, digital watermarks, digital fingerprints and digital rights management. This was hard going and there was lots of articles and websites to work through during the block and TMA.

Block three was probably the hardest on mobile broadband. It covered evolution of mobile phones including all the protocols and technologies used and this block involved a lot more calculations. The TMA for this was again a long one and required a lot of work.

The exam was fairly predictable compared to previous years and overall I got a distinction and so was happy.

Overall a great module.

I have to say this course was tough going and I come from an IT background. If you are studying this course for an ICT degree (B38) and have no prior experience of digital technology get ready for a tough ride.

However, I found the course very interesting and most informative, especially Block 2 - intellectual property and security issues. It will most certainly ground you for future higher level study in computing technology or a career in IT. Although I worked in IT for a number of years I never managed to learn and understand most of these very basic fundamentals about wireless and terrestrial technology. I sadly could not sit the exam and did not pass this course, but did pass the course work even though I also missed the final TMA.

Life is full of surprises and what I would say is make sure you can sit the exam for this course if you want to pass and make sure if you are family committed that you have 100% support before you even register for the course. Your life will no longer be your own and a masters degree in juggling would come in handy. On the whole I did enjoy it, but it was hard work and you will feel at times (if you are new to technology) as if you have made a horrible mistake. It's hard going get ready.

Module satisfaction survey

The figures below are taken from a survey of students who sat the exam/completed the end-of-module assessment for the February 2013 presentation of T325. The survey was carried out in 2014. 37.1% of our students responded to the survey covering what they thought of 10 aspects of the module. See this page for the full text of questions and more information about the survey.

Overall, I am satisfied with the quality of this module 87.9 %
Overall, I am satisfied with my study experience 89.4 %
The module provided good value for money 76.9 %
I was satisfied with the support provided by my tutor/study adviser on this module 82.8 %
Overall, I was satisfied with the teaching materials provided on this module 81.8 %
The module met its stated learning outcomes 95.5 %
I would recommend this module to other students 78.1 %
The module met my expectations 84.8 %
I enjoyed studying this module 77.3 %
Overall, I was able to keep up with the workload on this module 72.3 %
Faculty comment: "While recognising the limitations of the survey due to the low response rate of under 50%, we are pleased with the high positive response to nearly all of the survey questions. Students seem to be satisfied with most aspects of the module and with their study experience. We note however that although most respondents were able to keep up with workload, there was still a significant minority saying that they had problems with this aspect of the module. The module team is aware that T325 contains a large quantity of material and covers a wide range of topics so we are now giving more advice on the priority areas, to help students focus their study and manage their workload. It is also important for students to be sure that they have the appropriate pre-requisite knowledge as outlined in the module description before embarking on the module."
