The installation of 5G in TCU is imminent. By conducting inspections on the manufacturing line as "OTA tests," it is possible to shorten inspection time (reduce tact time).
TCU (Telematics Control Unit), T-BOX, DCM (Data Communication Module) testing solutions require various RF tests such as LTE, 5G, WiFi, BT, UWB, and FiRa. Morita Tech's OTA (Over The Air) testing solution utilizes a "near-field measurement" antenna coupler, enabling OTA testing in a desktop-sized compact shielded box. It supports MIMO, is space-saving, and can be automated. In the mass production phase, it contributes to reducing inspection costs: - Shortened inspection time due to the OTA testing environment (reduced takt time) - Automation - Non-contact testing - Resolution of issues caused by contact pins in traditional RF coaxial connector connections.

Company information
Morita Tech has been an innovation company since its founding, utilizing four solution capabilities: "5G," "EMC," "Shielding," and "High Frequency," to continuously realize products and technologies that solve challenges in various industrial businesses. In recent years, we have developed a "Compact OTA (Over The Air) Testing Environment" equipped with a short-range transmission and reception device called "Antenna Coupler," which has received great acclaim from telecommunications carriers and local 5G operators, and has been widely adopted in their "labs." In local 5G, it is used as a desktop OTA testing environment and interoperability testing system for the development and verification of base stations and terminals utilizing open source. Additionally, our product lineup includes various solutions as applied products for EMC visualization solutions aimed at achieving carbon neutrality (decarbonized society), such as "visualization of secondary batteries, visualization of partial discharge, and visualization of transient noise." We have four core departments and technologies in-house: "Mechanical and Structural Design," "Electrical Design," "Software Development," and "Manufacturing and QA," and we are fully committed to meeting our customers' expectations and demands while building long-term mutual trust relationships with them.
