This deliverable is an intermediate report on the activities towards a collection of common WHERE2 channel models. The report introduces the heterogenous simulation scenario and summarizes the activities and achievements in WP1 to simulate such a scenario. In WHERE2 two aspects of heterogeneity are considered: the radio access technologies and the environments. As such, investigations with respect to narrowband, wideband and ultra wideband channel characterization in multi-link scenarios are reported. Furthermore, indoor
and indoor-to-outdoor environments are considered. The channel variability due to human crowd activity and the variations of the antenna response are investigated as well.
