Building of a corporate brand

From mobile phones to ultra-high-speed optical communication and digital broadcasting—telecommunications networks are deeply integrated into daily life as a part of the social infrastructure that supports a safe, secure and comfortable society. Anritsu's measuring technology serves as mother technologies.
Having developed a wide range of communication measuring instruments to test radio waves and signals flowing through networks, Anritsu facilitates the construction of telecommunication networks that open new avenues for communication.

Sure connection and sure transmission—measuring technologies that support mobile communication

Since their appearance in the 1980s, mobile phones have benefited from rapid technological innovation. Today's models, however compact, are replete with convenient functions such as Web browsers, music and video download capabilities, and even pay-by-phone services. With seemingly unlimited potential, these devices will soon enjoy the commercial availability of Long Term Evolution (LTE), a next-generation mobile-phone communication system that allows high-speed, large-capacity communication at the level of optical fiber, slated for as early as 2010.
Before new mobile phone models are released into the market, various stages must be completed, from prototype development and mass production to network construction and maintenance. Testing is conducted at every stage to confirm reliable communication performance, and Anritsu's measuring technology has a key role in this since mobile phone transmission waves are invisible.
Anritsu provides measuring equipments that display radio waves, not visible to the human eye, in graphs and waveforms for analysis. The company's wealth of solutions—from the generation of test signals during the prototyping to the construction of simulated networks, the inspection of manufacturing sites during mass production, and the quality assessment of waves transmitted around us—supports the evolution of mobile phones in various settings, thereby contributing to the realization of convenient mobile communication.

Measuring technology supports information pathways via submarine cable to the home

Popular Internet content is now shifting toward video, and services that offer TV programs via the Internet are already available. These high-speed and large-capacity communication services are made possible by optical fibers running from the submarine to the home. Bending or breakage, however, can cause the signal quality of optical fiber to deteriorate. Disconnections can even occur from cicadas laying their eggs into the fibers, and identifying impaired areas of sheathed optical fiber is impossible with the human eye.
To address the problem, Anritsu developed a variety of measuring instruments that, with simple operation, are capable of locating breakages in optical fiber within a ten-meter stretch of the thousands of kilometers of cable that connect, even via submarine cable, individual homes.
