Title: Takayuki Ishiguro: Innovator in Mobile Communication Systems

Introduction

Takayuki Ishiguro is a prominent inventor based in Yokosuka, Japan. He has made significant contributions to the field of mobile communication, holding a total of 11 patents. His work focuses on enhancing communication systems while optimizing power consumption and efficiency.

Latest Patents

One of Ishiguro's latest patents is a control device for mobile communication systems. This innovative device enables seamless switching of communication from one system to another, significantly reducing the power consumption and workload of mobile terminals. The control device is designed for use in a communication system that includes both a first and a second mobile communication system, along with a mobile terminal that communicates with the first system. It features a position measuring unit that determines the mobile terminal's location, a judgment unit that decides whether to switch communication systems based on this position, and a switching unit that executes the switch as determined by the judgment unit.

Another notable patent involves a radio communications system and method. In this system, a radio terminal and a radio relay communicate through a non-TDMA radio communications system. An interference measurer assesses the degree of interference in each radio slot of the channel. Based on this measurement, a decision maker determines whether the communication can continue. If it cannot, a switcher transitions the communication to a TDMA system.
