[Product Example] Simple Radio Wave Shielding Box + Linear Slider

It can be equipped with a horn antenna, and a laser pointer can also be installed for positioning confirmation!

We offer a simple assembly millimeter-wave compatible RF shielded box and the HQ303 series linear slider, which allows for adjustable measurement distances. The linear slider and vector network analyzer can be remotely controlled to automatically measure the positional characteristic patterns in the RF domain. By changing positions, we repeatedly record the signal levels at specified frequencies, compiling a cohesive set of positional characteristic data. Measurement distances and the range of fixture movement can be adjusted to meet your needs. For more details, please contact us. 【Features】 - Automatic measurement of positional characteristic patterns in the RF domain - Compilation of cohesive positional characteristic data - Mobile with casters - Capable of mounting a horn antenna, and a laser pointer can also be attached for positioning confirmation - Ability to confirm alignment using a laser *For more details, please refer to the related links or feel free to contact us.

[Construction Case] Relocation of Radio Wave Shielding Box

[Construction Case] Relocation of Radio Wave Shielding Box

Even buildings without elevators can be disassembled and brought in! It can also be carried up the stairs.

This time, we used the "TSD-MU series," a radio wave dark box that can be expanded and disassembled, to deliver it in a disassembled state to a location without an elevator and reassemble it. Since the parts are brought in pre-installed, the on-site work only involves bolting them in place. It can be disassembled and brought into buildings without elevators. It is also possible to carry it up the stairs. 【Construction Overview】 ■ Delivery (relocation) to a place without an elevator ■ Installation *For more details, please refer to the related links or feel free to contact us.

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.

Radio Wave Shielding Box System for Production Lines

Radio Wave Shielding Box System for Production Lines

[Application Example] Communication Evaluation of Wireless Modules

【Product Introduction】 ■Handheld Spectrum Analyzer Compact, lightweight, battery-operated (low power consumption), and low cost. Despite being a handheld type, it offers performance comparable to larger models. ■EMI Shielded Enclosure/Shield Box Low cost, lightweight, and short delivery time! High-quality, reliable, and cost-effective EMI shielded enclosures and shield boxes provided by measurement instrument manufacturers. The EMI shielded enclosure has the following functions, allowing for accurate characteristic measurements of the DUT. 1. Provides an environment unaffected by external electromagnetic waves. 2. Blocks leakage of electromagnetic waves to the outside. 3. Reduces interference within the EMI shielded enclosure. By utilizing these characteristics and combining them with other measurement devices and testing evaluation terminals, they can be permanently installed as production line equipment for quality inspection and functional testing of various wireless modules (such as wireless LAN and Bluetooth) equipped devices.

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?

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.*
