The rapid urbanization in African cities has led to increased demands for robust digital infrastructure. A comprehensive literature search was conducted using academic databases, focusing on relevant research articles from to the present. The analysis identified a significant proportion (48%) of the reviewed studies emphasising the potential for enhanced data transfer rates and reduced latency in urban environments. While the majority of studies highlight theoretical benefits, there is a notable gap in practical implementation and evaluation within Tanzanian cities. Further research should prioritise pilot projects to assess the real-world impact of 5G technology on digital transformation efforts. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.
