Using a hand-in type anechoic box, the environment to reproduce out-of-service and unstable communication state will be provided.


Recently, the applications of smartphone are very popular. The outdoor use is increasing because carrying is easy, but it often happens that the communication state gets worse in moving, buildings and underground shopping areas.

If the area is out-of-service or the radio wave weakens suddenly, the data communication failure will occur. Due to this communication failure, the data may be damaged or billing error will occur. When developing and managing applications, it is necessary to take measuresagainst such communication failures.

An anechoic box or shield box is a desktop box for blocking radio waves. Our hand-in anechoic box can block the radio waves from the smartphone or tablet terminal (making it out-of-service) and operate the screen with bare hands. So the operation check of the application can be performed while actually operating it under out-of-service environment.


On the state in which radio waves are blocked, you can actually operate it with bare hands while watching the terminal screen through the shield window.
