Ray-Optics Simulations of Outdoor-to-Indoor Multipath Channels at 4 and 14 GHz
Pasi Koivumäki, Aki Karttunen, Katsuyuki Haneda
Radio wave propagation simulations based on the ray-optical approximation have been widely adopted in coverage analysis for a range of situations, including the outdoor-to-indoor s…
Path Loss, Angular Spread and Channel Sparsity Modeling for Indoor and Outdoor Environments at the sub-THz Band
Dimitrios G. Selimis, Mar Francis De Guzman, Fotis I. Lazarakis +3
In this paper, we present new measurement results to model large-scale path loss, angular spread and channel sparsity at the sub-THz (141-145 GHz) band, for both indoor and outdoor…
On the Feasibility of Out-of-Band Spatial Channel Information for Millimeter-Wave Beam Search
Peize Zhang, Pekka Kyösti, Katsuyuki Haneda +2
The rollout of millimeter-wave (mmWave) cellular network enables us to realize the full potential of 5G/6G with vastly improved throughput and ultra-low latency. MmWave communicati…
Impacts of Real Hands on 5G Millimeter-Wave Cellphone Antennas: Measurements and Electromagnetic Models
Bing Xue, Pasi Koivumaki, Lauri Vaha-Savo +2
Penetration of cellphones into markets requires their robust operation in time-varying radio environments, especially for millimeter-wave communications. Hands and fingers of a hum…
Electromagnetic-Thermal Analyses of Distributed Antennas Embedded into a Load Bearing Wall
Lauri Vähä-Savo, Katsuyuki Haneda, Clemens Icheln +1
The importance of indoor mobile connectivity has increased during the last years, especially during the Covid-19 pandemic. In contrast, new energy-efficient buildings contain struc…
6G Radio Requirements to Support Integrated Communication, Localization, and Sensing
Henk Wymeersch, Aarno Pärssinen, Traian E. Abrudan +10
6G will be characterized by extreme use cases, not only for communication, but also for localization, and sensing. The use cases can be directly mapped to requirements in terms of…
