Environment Induced Shadowing of Urban Millimeter-Wave Access Links

In this letter, we investigate how environment induced shadowing influences a 28.5 GHz access link in an urban open square scenario. Shadowing is caused by cars, buses, lorries, and pedestrians passing between the small cell base station and the mobile user terminal. We isolate typical single shadowing events and provide a model for their description. We also present statistical evaluations that can be used as input to 5G access channel models.
