Automotive Communication Technology That Supports the Safety and Promotes the Spread of Digital Keys

Keys, which are essential for accessing vehicles, have evolved over time from traditional physical keys to keyless entry systems and smart keys. Currently, digital keys are being developed to adapt to emerging mobility concepts like CASE. In this article, we will outline the fundamental concepts of digital keys and the communication technologies that enable their functionalities.

FDMA, TDMA, and CDMA Multiple Access: Effective Utilization of Bandwidth (2)

The smartphones used by all sorts of people today are capable of transferring audio, image, and video data without interference. This is possible thanks to technologies that prevent problems such as the overlapping of different streams of data or interference from noise. This article describes two such technologies: “multiplexing,” which is aimed at enabling efficient utilization of radio signals, and “multiple access,” which makes use of multiplexing technology.

Installing Electronic Circuits of Dramatically Increasing Size into Compact Devices - Murata's MLCC for 5G Smartphones (Part 2 of 2)

In Part 2, we talked about the difficulties in developing MLCC-specific manufacturing technology and the technology that solved our issues, as well as why Murata’s development system is so strong and continues to lead the way in miniaturizing and increasing the capacitance of MLCCs. Murata engineers also explained the prospects for further miniaturization and capacitance expansion of MLCCs.
