Telecommunications engineering personal statement example

Why do you want to study this course or subject?

My interest in telecommunications started with a practical annoyance: the back bedroom of our house never got a usable Wi-Fi signal. Moving the router around taught me nothing useful, so I started reading about why 5 GHz signals struggle with brick walls while 2.4 GHz travels further but carries less data. That trade-off between bandwidth, range and interference turned out to sit underneath almost everything I later found interesting, from mobile networks to the fibre being pulled down our street last summer.

What draws me to the subject is that it combines physics I enjoy with a clear purpose. In Physics I liked waves and superposition more than any other topic, partly because the maths behind them explains real behaviour: why two signals can cancel, why a reflected path arrives late and smears a symbol, why an antenna's length relates to wavelength. When I read about modulation schemes and learned that increasing the number of points in a constellation squeezes more bits into the same channel but makes each one easier to mistake, it felt like the same idea I had met as measurement uncertainty, applied to an engineering decision.

I am also interested in the systems side. A phone call crossing a city involves radio access, switching, optical transmission and protocols agreeing on how to recover from loss, and I want to understand how those layers are designed to work together rather than treating any one of them as a black box. Topics I am keen to study properly include signal processing, error-correcting codes, antenna design and network architecture, since at the moment I only understand them at the level of analogies.

Longer term, I would like to work on infrastructure that improves connectivity in places where it is currently poor, including rural areas like the villages near my grandparents where mobile coverage still drops out on the main road. That feels like engineering with visible consequences, and a degree in telecommunications engineering is the route into it.

How have your qualifications and studies helped you to prepare?

I am studying Maths, Physics and Computer Science, which between them cover most of the groundwork the course assumes. In Maths, the work on trigonometric identities, series and calculus has been the most directly relevant; being able to differentiate and integrate sinusoids confidently made it far easier to follow introductory reading on signals. I have started working through the mechanics and statistics content with more attention to error and probability, because I noticed that descriptions of noisy channels rely on treating disturbance statistically rather than as a single fixed value.

Physics has given me the wave and electricity foundations: standing waves, the inverse square law, capacitance and the behaviour of alternating current. Our practical work on resonance in an LC circuit was the point at which tuning a receiver stopped being mysterious. I take care with practical write-ups, particularly with identifying which uncertainty dominates a result, and I was asked to demonstrate our oscilloscope procedure to the year below.

Computer Science has been useful in less obvious ways. Studying how TCP handles acknowledgements and retransmission, and how data is represented in binary, gave me vocabulary for the network side. I chose to write my programming project in Python and spent longer than expected on handling malformed input, which turned out to be good preparation for the sensor work I describe below.

For my Extended Project I wrote about factors affecting radio propagation in urban environments, comparing free-space loss predictions with the rough measurements I could take myself. Researching it taught me to read technical material selectively and to be honest about the limits of amateur measurement: my results showed a trend rather than anything precise, and explaining why was the most valuable part of the write-up.

What else have you done to prepare outside of education, and why are these experiences useful?

My main independent project has been a low-power radio link between our house and my family's allotment shed, about four hundred metres away. Using two LoRa modules and an inexpensive microcontroller, I send a temperature and soil moisture reading every fifteen minutes so my mum knows whether the greenhouse needs attention. Getting it working took several months of evenings. The first version failed intermittently until I realised I had the antenna coiled inside a metal biscuit tin I was using as an enclosure. I also had to reduce the transmission rate after finding that battery life mattered more to us than frequent updates, which was my first real experience of designing against a constraint rather than for a specification. I keep a logbook of range tests taken at different points along the path, and I can see how much the readings vary with weather and foliage.

I help run the electronics club at college, mostly by preparing soldering practice boards and talking newer students through reading a circuit diagram. Explaining a potential divider to someone who has not met it yet has forced me to be much clearer about what I actually understand.

On Saturdays and Sundays I work in the café at a garden centre, taking orders, operating the till and clearing tables during long, busy shifts. It is not technical work, but it has taught me to stay organised when several things need doing at once, to handle complaints calmly and to work with people much older and much younger than me. I have also become the person colleagues ask when the card reader loses its connection, which is usually a matter of patience rather than expertise.

Outside college I play in a local badminton league and I am gradually teaching myself to repair second-hand radios and speakers, with mixed success so far. I am used to balancing paid work, study and a project that only progresses if I make time for it, and I expect that habit to serve me well on a demanding engineering degree.
