Study on Outdoor-to-Indoor Channel Characteristics at 20 GHz Bands

摘要

The next generation (5G) mobile communication system has been the focus of studies recently. One of the approaches to enable this system is utilizing the high-SHF band (over 6 GHz) and EHF band (mainly 30 - 100 GHz). Considering scenarios using high-SHF and EHF bands for small cells, to design radio links with high accuracy, the channel characteristics of "Outdoor-to-Indoor (021) propagation" must be clarified. In this paper, we clarify 02I channel characteristics at 20 GHz band based on the measurement using a channel sounder with a 50 MHz bandwidth.
