Title: **Innovative Contributions of Toyohiro Kayanuma in Mobile Terminal Testing**
Introduction
Toyohiro Kayanuma, an accomplished inventor based in Atsugi, Japan, has made significant contributions to the field of mobile telecommunications. With a total of three patents under his name, Kayanuma's innovations are aimed at enhancing the functionality and efficiency of mobile terminal testing.
Latest Patents
Kayanuma's latest patents include a mobile terminal testing device, a mobile terminal testing system, and a testing method designed for Non-Standalone (NSA) mobile terminals. His mobile terminal testing device and system are crafted to reduce processing loads during the testing of mobile terminals that support NSA technology. Specifically, the first device operates as an LTE base station, while the second device acts as a 5G NR base station. When testing a mobile terminal supporting NSA, the second device generates a control signal for 5G NR, which is then transmitted to the first device. The first device subsequently sends this control signal to the mobile terminal in accordance with LTE protocols.
Another notable invention includes a mobile terminal testing device that features a reproduction unit capable of outputting at least one reproduced baseband (BB) signal. This device adds frequency-shifted BB signals to the reproduced BB signal and generates a multicarrier test signal for the User Equipment (UE). An analyzer within the device analyzes the response from the UE to calculate throughput and acquire Reference Signal Received Power (RSRP).
