In this paper, we demonstrate the communication capabilities of light-fidelity (LiFi) systems based on high-brightness and high-bandwidth integrated laser-based sources in a surface mount device (SMD) packaging platform. The laser-based source is able to deliver 450 lumens of white light illumination and the resultant light brightness is over 1000~cd/mm^2. It is demonstrated that a wavelength division multiplexing (WDM) LiFi system with ten parallel channels is able to deliver over 100 Gbps data rate with the assistance of Volterra filter-based nonlinear equalisers. In addition, an aggregated transmission data rate of 4. 8 Gbps has been achieved over a link distance of 500 m with the same type of SMD light source. This work demonstrates the scalability of LiFi systems that employ laser-based light sources, particularly in their capacity to enable high-speed short range, as well as long-range data transmission.
