There is a increasing demand for high speed data services while travelling on trains and other means of public transportation. Hence, an alternative technology to radio frequency (RF) communications called free space optics (FSO) could be used to provide truly high-speed broadband services in trains. This paper presents a Lambertian source modelling of FSO(More)
In this work, a free space optical (FSO) communication link for the ground-to-train system is experimentally demonstrated in the laboratory environment. The system can be used to provide high speed broadband services on fast moving trains. A line of sight (LOS) FSO communications link is presented and the measured Q-factor performance along the rail track(More)
In this work, a line-of-sight free space optical (FSO) link for the ground-to-train communications is presented. The measured &#x00DF;-factor performance along the rail track for the proposed prototype system was analysed. We demonstrate a downlink error-free communications (i.e., a bit error rate of 10<sup>-6</sup>) over four regions of the track using(More)
