SoftBank Corp. (“SoftBank”) and its subsidiary HAPSMobile Inc. (“HAPSMobile”) developed a new global model that can estimate radio wave interference at high altitudes and enable the design of network ...

It is fitting in a book about wireless communication to look at the phenomena that lets us transfer information from one point to another without any physical medium—the propagation of radio waves. If ...

The increase in mobile communication technology has led to concern about potential health effects of radio frequency electromagnetic fields (RF-EMFs) from mobile phone base stations. Different RF-EMF ...

SoftBank Corp. (President & CEO: Junichi Miyakawa, “SoftBank”) today announced it developed a new “Model for Predicting Direction of Radiowaves Arriving at Mobile Station” as part of its “HAPS ...

A large number of things—some desirable, some not—can happen to a radio wave on its way from one place to another. In the simplest case two antennas (a transmitter and a receiver) are located so that ...

ABSTRACT Radio wave propagation on low-altitude paths over the ocean above 2 GHz is significantly affected by negative refractivity gradients in the atmospheric surface layer, which form what is often ...

A method to analytically express the performance of wireless communication systems when using reconfigurable intelligent surfaces (RIS) was successfully developed by researchers at Tohoku University, ...
