Modeling Multi-Frequency Characteristics for Classroom and Hall Scenarios at 2-4, 9-11 and 27-29 GHz Bands

Abstract: This paper investigates the wideband channel characteristics obtained in a classroom and a hall indoor scenarios at 2-4, 9-11 and 27-29 GHz. A virtual uniform circular array (UCA) based channel sounding system was utilized to capture wideband spatial channel characteristics. The propagation parameters of multipath components (MPCs) were estimated by using a high resolution parameter estimation (HRPE) algorithm. The estimated MPCs are further grouped into clusters via a novel clustering identification algorithm… Show more

“…We conjecture that the larger power loss is caused by the multiple bounces occurring between the buildings. The numbers of clusters from both methods are much smaller, compared to those found for LoS indoor scenarios at similar frequency bands, where a mean value of 14.4 was found for the classroom, a mean value of 11 for the hall [5], and a mean value of 21 for the hall and corridor scenario [4] including both LoS and NLoS scenarios. We postulate that it is caused by sparse IOs in outdoor scenarios.…”

“…Additionally, the values of β of both methods are much higher than that found in indoor scenarios at similar frequency bands, which are 2.27 in the classroom, 1.56 in the hall [5], and 3.66 in the NLoS corridor scenario [4]. It means more rapid variations of cluster power versus distance in outdoor scenario.…”
