This research addresses overheating in 5G base stations, where vertically mounted electronics create dangerous hotspots. By using passive vapor chamber cooling, heat is efficiently redistributed without added energy use. Experimental and modeling work shows vapor chambers improve reliability and sustainability, supporting faster, more stable 5G and future network infrastructure.

This research seeks to reduce the energy consumption of 4G and 5G networks—currently about 3% of global usage—by identifying the factors that drive it. By modelling how elements like signal noise affect energy demands in antennas and processing hardware, the project aims to guide the design of more efficient, sustainable mobile networks.
