What is an anechoic chamber? Is it really necessary?

峰光電子 峰光電子
An anechoic chamber is a "special room" used to test the performance and safety of wireless devices. In a regular room, invisible waves from smartphones, Wi-Fi, and televisions are present, making it impossible to conduct accurate tests on devices. Therefore, an anechoic chamber is a special space that "completely shuts out external waves" and also ensures that "waves inside do not leak outside." When is it used? - Testing and inspection of wireless devices - Testing for obtaining technical standard conformity certification (Giteki) - Confirming that there is no interference from waves to other devices In other words, it is "an essential place for creating accurate and reliable wireless devices." What is the inside of the room like? - The walls, ceiling, and floor are covered with "sponge-like materials that absorb waves (wave-absorbing panels)." - The entire room is covered with a metal shield to prevent external waves from entering. Why is it so important? Wireless devices can significantly impact medical equipment, airplanes, and fire department radios, depending on where they are used. That is why it is crucial to thoroughly verify that they emit waves correctly and safely in a place free from external influences, which is the anechoic chamber.

Advanced wireless technology for the mobility industry.

In cars equipped with various wireless systems, wireless technology is one of the essential technologies!

As you all know, cars are equipped with many wireless systems. They are indispensable for improving safety and convenience. - Immobilizer (LF band) - FM (MF band) - AM (HF band) - Keyless entry, GPS (UHF band) - ETC/DSRC (SHF band) - Collision avoidance detection (millimeter wave) The frequency bands used are varied. Until now, many wireless technologies have been used for preventive safety to prevent accidents, such as collision avoidance. Based on the vast amount of accumulated information, it is said that autonomous driving technology will increase exponentially in the future. Wireless technologies such as millimeter wave radar, LiDAR, and GPS are essential for autonomous driving, and high reliability is also required. "Continuous wireless" and "wireless that compensates when interrupted" will be demanded at even higher levels going forward. Our company not only has a track record of supplying antennas for vehicles but also has experience supplying antennas for satellites launched on rockets. To meet various needs, we provide products with meticulous designs while conducting measurements in an anechoic chamber.

旧式と新型のロボット対比.jpg

Changing Roles of Robots in the Manufacturing Industry

From strong to gentle! Wireless technology in robots that require cooperation with humans.

The image that comes to mind when hearing "robot" varies greatly depending on the era. Those who imagine a robot as 【operated by humans / large / powerful】 may be from a slightly veteran generation like mine. On the other hand, the recent trend is to envision robots as 【autonomous / small / delicate】. Against the backdrop of this change in values, robots themed around "collaboration," where humans and robots support each other in the same workplace, are currently assisting in environments struggling with labor shortages. These robots rely on 【wireless technology】 to achieve functions such as 【sharing location information】【remote monitoring】【coordination of multiple devices】. Additionally, by correctly understanding 【wireless technology】, we can ensure safety and security regarding various types of wireless communication and the 【interference】 that can occur when using many robots at once. By eliminating the constraints of cables, 【wireless technology】 enables flexible arrangements and collaborative work with humans, acting as the "invisible nerves" of robots and supporting flexible and safe working methods. *For more details, please feel free to contact us.
