CDR Sample for Telecommunications Engineer (263311)

This final year project focused on developing a functional 5G cellular network for a simulated urban environment to provide high-speed, low-latency communication. My core responsibilities were:

I was responsible for the end-to-end design and implementation of a 5G network segment. I began by defining the system requirements, including coverage area, capacity, and latency targets. I designed the radio access network (RAN) architecture, including antenna placement and beamforming strategies, and configured the core network elements. A critical task was ensuring optimal resource allocation and handover procedures for a seamless user experience. I used network simulation tools to validate the design and then implemented a prototype using software-defined radio (SDR) and open-source 5G core components. Finally, I evaluated the network’s performance against key performance indicators (KPIs), including throughput and latency.

This project focused on designing and implementing a high-speed optical fibre communication link to support data transmission over a metropolitan area. My core responsibilities were:

I was responsible for the complete lifecycle of the optical fibre link. I initiated the project by gathering requirements for data rate, transmission distance, and signal integrity. I then designed the optical link budget, selecting appropriate single-mode fibres, optical transceivers, and amplifiers (EDFAs). A key challenge was managing chromatic dispersion and polarisation mode dispersion. I used specialised software to simulate the link performance under various conditions and optimised parameters to meet the specifications. I oversaw the physical installation and splicing of the fibre optic cables and configured the network equipment. Finally, I conducted thorough testing, including BER (Bit Error Rate) and power budget measurements, to validate the link’s performance.

This project involved enhancing the security posture and optimising the performance of a corporate Local Area Network (LAN). My core responsibilities were:

I was tasked with conducting a comprehensive network security audit and implementing security measures, alongside performance optimisation. I began by assessing existing vulnerabilities and identifying potential threats within the corporate LAN. I designed and implemented a multi-layered security architecture, including firewall rules, intrusion detection/prevention systems (IDS/IPS), and VPN configurations. A critical aspect was ensuring data privacy and integrity without compromising network speed. I configured routing protocols for efficiency and implemented QoS policies to prioritise critical traffic. I also developed and enforced security policies and procedures for users. Finally, I monitored network traffic and logs to ensure the effectiveness of the security measures and optimised network devices for peak performance.
