Professor Kai-Kit Wong's research lab specializes in advanced wireless communication systems, with a strong focus on innovative antenna technologies and spectral efficiency enhancement for next-generation mobile networks. The lab explores fluid antenna systems (FAS) that enable dynamic spatial reconfiguration to improve system reliability and capacity, particularly in challenging propagation environments. Research also extends to 6G mobile communications, emphasizing high energy and spectral efficiency, robust signal processing, and reliable performance over fading channels. The lab combines theoretical analysis with practical system design to address fundamental limits in wireless connectivity.

Fluid antenna represents a concept where a position-flexible antenna can switch its location freely within a given space. Recently, it has been demonstrated that even with a tiny space, a single-antenna fluid antenna system (FAS) can outperform an L -antenna maximum ratio combining (MRC) system in terms of outage probability if the number of locations (or ports) the fluid antenna can be switched to, is large enough. This letter aims to study if extraordinary capacity can also be achieved by FAS
While 5G is tasked to transform our lives for the better over the next 10 years, next-generation mobile communications, a.k.a. 6G, will undoubtedly demand even higher energy and spectral efficiencies capable of providing myriads of new services and experience to users everywhere they go. Although our technologies do evolve from one generation to the next, the root of the ambition in mobile communications has always been to ensure reliable performance from an uncertain, fluctuating medium.
