NG-BTS with Fluid Antenna Systems

“Be formless… shapeless, like water!” These iconic words from Bruce Lee capture a philosophy of adaptability and freedom—principles that now inspire a bold new direction in wireless communication. This talk introduces the concept of Next-Generation Base Transceiver Stations (NG-BTS) empowered by Fluid Antenna Systems (FAS), a reconfigurable antenna technology that embodies this philosophy at the physical layer.

FAS enables dynamic reconfiguration in both shape and position, granting unprecedented spatial agility and unlocking new degrees of freedom for wireless systems. In this talk, we begin by formally defining the Fluid Antenna System and discussing its integration with existing mobile infrastructure. We then explore how FAS can fundamentally reshape the design and capabilities of NG-BTS architectures—enhancing spectral efficiency, improving coverage, and tackling challenges such as interference, mobility, and channel hardening. The presentation concludes with an overview of hardware implementation efforts and early experimental results, illustrating the transformative potential of FAS for future-generation wireless networks.
