Ir. Dr. Grace Lim's research interests for the past two decades have revolved primarily around radio propagation measurement and modeling in wireless communication environments. She adopts the fundamental, physics-based, and empirical approach to modeling random electromagnetic waves in special and not-well-explored wireless propagation environments such as indoor stairwells, the outskirt of periodic building fa?ade, open-trench drains in Southeast Asia, pedestrian tunnels, and natural caves in Malaysia. All these findings are expected to collectively contribute towards accurate planning and implementation of wireless communications systems in complex environments.

Of late, Dr. Grace Lim has explored the use of machine learning to do propagation prediction, which contributes toward optimal base station planning and placement. This is especially relevant for 5G and other future generations of cellular networks. As an example, she and her group has proposed a machine learning-based method to rapidly predict path loss in an urban area using data extracted from online sources to aid in cellular coverage estimation in an area. The outcome of this work is useful for an urban environment that sees rapid development and changes to its landscape. In such scenario, the location of the existing base station will benefit from adjustment for optimal coverage provision.
