In this paper, a geometry-based stochastic scattering model (GBSSM) for wideband multiple-input multiple-output mobile-to-mobile (M2M) isotropic scattering fading channels is proposed. The model is based on a two-ring scattering model which can be applied for the line-of-sight (LOS) and non-LOS scenarios by considering the single- and double-bounced components. The target of developing the GBSSM is to realize the channel in typical environments for future internet-of-thing networks such as shopping malls, logistics centers and so on to be used in the link and system level simulations in M2M new radio systems. The channel realization in this paper is more straight forward and concise to study the channel characteristics compare with the too complicated analytical solutions available so far.
