This paper compares the received signal characteristics obtained for two access point (AP) mounting arrangements commonly encountered in indoor millimeter wave wireless networks, namely ceiling- and wall-mounted APs. To facilitate this, we consider three key user equipment (UE) usage scenarios, in which a user imitated making a voice call, operating an app and carrying the device in a pocket. For each of these UE cases, we investigate the fading characteristics of the millimeter wave channel at 60 GHz as the user walk toward and then away from the ceiling- and wall-mounted APs. Following this, the lognormal and κ-μ distributions are shown to provide a good fit to the shadowed and multipath fading, respectively. Based on the parameter estimates and model fitting, it is found that the choice between a ceiling- and wall-mounted position for the AP is dependent on the UE use case and whether the device is in line-of-sight (LOS) or non-LOS (NLOS).
