The History of Wired Communication
The first wireless device that allowed people to speak to another person far away was the TYK radiotelephone. It was created by Annaka Electric Co., the forerunner of Anritsu, in 1914 – over 100 years ago. At that time, industrialization was underway in Japan and shipping became an even more crucial industry as a result. The first TYK radiotelephone facilities were therefore set up around Ise Bay in Mie prefecture, with equipment installed in the coastal city of Toba and on two nearby islands, Kami-shima and Toshi-jima Islands. The first words spoken were “Today’s weather is clear. Today’s weather is clear. This is Toba. This is Toba, Kami-shima, Kami-shima.” The system was primarily used for passage notifications by ships traveling in the bay, resulting in greater safety. Our early TYK radiotelephone technology remains an important part of telecommunications history – it was the world’s first wireless voice telecommunication device and the precursor to the mobile devices we use today.
Japan’s first public telephone service was set up in 1900. Public phones (known as “automatic telephones” at the time) were installed at two major stations in Tokyo, Shimbashi Station and Ueno Station. The first of these phones were magneto phones powered by a hand crank. These were later replaced by common-battery phones that allowed users to place calls without a hand crank, a change that prompted greater spread of public phones. The popularization of public phones was largely the work of Kyoritsu Electric Co., a company formed by a merger of Sekisan-sha, another forerunner of Anritsu. Kyoritsu’s technology was so highly regarded that Kyoritsu was nationally designated as a common-battery automatic telephone manufacturer. Our public phones were the start of an era, and were updated with each new technology from phone cards to digitalization. They were exported to various overseas countries including Australia, Mexico, South Africa and China, where they helped to improve outdoor communication facilities.

In the 120 years since its establishment, Anritsu has been the starting point of many kinds of wireless and wired communication devices. We have achieved this through a constant cycle of figuring out what people needed in each new age and creating new technology out of existing technology. Our measuring instruments are a symbolic example of this. Measuring instruments are high-tech devices for measuring signals and radio waves, and are essential in the development and production of communication devices. Anritsu began producing its own measuring instruments in-house to evaluate its wired and wireless communication devices. Our management saw a greater scope of potential and began commercializing these instruments, and signal generators, electric field strength meters and other instruments were launched. A particularly successful example is our measuring instruments for microwave circuits. Microwave circuits were a key part of a plan by Nippon Telegraph and Telephone Public Corporation (now NTT, one of Japan’s largest phone companies) to expand Japan’s telegraph and telephone services after World War II, and our measuring instruments played an important role in this initiative. We cemented our position in the test and measurement industry through overseas expansion of our business in measuring instruments for microwave circuits, including business from AT&T, the largest telecommunications company in the US. Since then, we have continued to play a part in the advancement and development of our information and communication-based society by creating measuring instruments that are the de facto standard in fields such as fiber optics, digital communication and mobile communication.
