Shielded box / radio wave dark box

Shielded box / radio wave dark box

As a measure for wireless system testing, we will make proposals tailored to the user's requests.

Wireless system tests must be conducted in anechoic spaces that are shielded from external noise and free from internal radio wave reflections. Radio wave dark boxes and shielded boxes are alternatives that reduce installation space and costs compared to radio wave dark rooms.

I tested the function that disconnects devices that continue to connect to WiFi despite poor signal.

[Application Case] Demonstrating the Truth and Lies of Wi-Fi

In the previous installment of this series, it was found that the timing for executing roaming over Wi-Fi (wireless LAN) is determined not by the access point (AP) but by the terminal side. Additionally, it became clear that some terminals do not roam quickly and only change their connection to the next AP after a while following a communication interruption. 【Product Introduction】 ■ Radio Shield MY1530 ■ High-Speed Programmable Attenuator MAT810 *For more details, please refer to the PDF document or feel free to contact us.

Is it really possible to be connected to Wi-Fi but unable to communicate?

[Application Case] Demonstrating the Truth and Lies of Wi-Fi

**Product Introduction** ■ Radio Wave Dark Box MY1530 *For more details, please refer to the PDF document or feel free to contact us.* Many readers may have the impression that "Wi-Fi (wireless LAN) is always accompanied by troubles." I often hear stories like "the connection drops" or "I feel like the Wi-Fi connection got slower after moving to the conference room with my PC." Among these troubles, what has recently caught my attention is the issue of "the Wi-Fi icon appearing on the smartphone screen, yet unable to connect" or "after moving a little, I can no longer connect, and it doesn't switch to LTE either." These are frustrating problems that are hard to understand, but they actually occur quite frequently. There are various causes, but this time I will introduce a case where "differences in signal strength of devices" is a contributing factor. *For more details, please refer to the PDF document or feel free to contact us.*

[Application Case] Demonstrating the Truth and Lies of Wi-Fi

【Product Introduction】 ■ Radio Shielded Box MY1530 *For more details, please refer to the PDF document or feel free to contact us. Wi-Fi (wireless LAN) communication uses the 2.4GHz and 5GHz bands. Among these, the 2.4GHz band is also used by devices such as microwaves and cordless phones, and it is widely known that these can interfere with Wi-Fi communication. *For more details, please refer to the PDF document or feel free to contact us.

Is high-speed "channel bonding" all good?

[Application Case] Demonstrating the Truth and Lies of Wi-Fi

【Product Introduction】 ■Radio Wave Dark Box MY1530 A large size that accommodates large test objects. A turntable can be installed as an option. For 802.11n and 11ac, there is a technology called channel bonding that allows multiple channels to be combined (that is, to widen the frequency range used) to increase the communication bandwidth, as shown in Figure 1. In particular, with 802.11ac, bonding can be done with a width of 80MHz, equivalent to four channels. This results in approximately four times the communication speed compared to a 20MHz width. *For more details, please refer to the PDF document or feel free to contact us.

Is it true that you can communicate via WiFi even 100 meters away from the access point?

[Application Case] Demonstrating the Truth and Lies of Wi-Fi

"How far can Wi-Fi (wireless LAN) communicate?" This is one of the questions frequently asked by users, but it cannot be easily answered as various conditions are involved. In the past, I have seen news and articles about various long-distance wireless LAN communication experiments, but what left an impression on me was the story of a successful wireless LAN communication test between islands. It was surprising to hear that they achieved communication over approximately 60 km using antennas with high directionality and gain on both the receiving and transmitting sides.
