Abstract

Visible light communications (VLC) and Millimetre wave (mmWave) systems are two emerging technologies for shortrange mobile communications. One of the limiting factors of both VLC and mmWave systems is the random orientation of
mobile devices that can significantly affect the channel gain in both systems. Since there is no proper model for device orientation, many studies have assumed that device orientation is fixed or modelled as a uniform distribution. To address this issue, an experimental study of mobile user behaviour is conducted and a statistical orientation model is proposed in this paper.
The results show that the probability density function (PDF) of the elevation angle follows a Laplace distribution. Based on the statistical orientation model, Monte-Carlo simulations are carried out to analyse the system performance of VLC and mmWave systems. The statistics of signal-to-noise-ratio (SNR)
are compared with the experiment-based simulation results in both VLC and mmWave systems.
