Reliable telecommunications networks are essential for economic development in Tanzania. The network's resilience is influenced by various factors such as signal strength, interference, and physical infrastructure. A PDE-based model was formulated to represent the telecommunications environment, including signal transmission models and interference sources. Finite-element methods were used for spatial discretization, ensuring a comprehensive representation of the network's complexity. Error bounds were analysed using variational principles to assess the accuracy of the numerical solutions. The analysis revealed that under certain conditions, the error in predictions decreased with higher mesh refinement, indicating improved model fidelity as resolution increased. This study demonstrated the effectiveness of PDEs and finite-element methods for enhancing telecom network reliability in Tanzania. The findings provide a robust framework for future research and practical applications. Further research should explore the impact of environmental factors on network performance and validate the model using real-world data from Tanzanian telecommunications networks.
