Evaluation of the performance of wireless LAN access points and client devices during the transmission of compressed large-capacity video/audio data.
- Protect data from adjacent frequencies that interfere with the carrier during data transmission. (For wireless LAN access points) - Connect decoded video/audio data to external devices for real-time verification (client terminal) - Use a high-speed programmable attenuator to create a simulation environment with added distance attenuation. By eliminating unwanted factors due to external influences, we check for dropped frames and freezing situations during playback on the client terminal side, especially when transmitting Hi-Vision size video from the access point. 【Product Introduction】 - Radio Shielded Box MY1520SW - I/F Module - SMA Cable - High-Speed Programmable Attenuator MAT800 - Dipole Antenna M306 *For more details, please refer to the PDF materials or feel free to contact us.

[Application Example] A broadband electromagnetic shielded chamber suitable for the development of multi-band/UWB radio devices and EMC evaluation.
【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 a measurement instrument manufacturer. There is an increasing demand to establish test environments that require wideband capabilities, such as the development of multi-band/UWB wireless devices and EMC evaluations, at the lowest possible cost. By achieving such environments with an EMI shielded enclosure, initial investment for setting up the environment can be minimized, and easy debugging can contribute to reducing the development turnaround time.
[Application Example] This is a comparison of the shielding performance between MY1510 and other companies' (overseas) RF shielded enclosures.
【Product Introduction】 ■Radio Wave Dark Box / Shield Box Taurus Series MY1510 A lightweight and portable compact size. Offered at a very affordable price of under 200,000 yen. ■IF Module A module equipped with AC, DC, LAN, USB, SMA, BNC, N, D-sub connectors and feedthroughs. An interface (such as AC power, LAN, USB ports, etc.) for connecting devices is essential for a radio wave dark box. When choosing a radio wave dark box, one of the performance metrics is its shielding performance, and it is crucial to consider whether this performance includes the interfaces. In fact, it is not an exaggeration to say that the performance of the interface section determines the shielding performance of the radio wave dark box. This application note compares the shielding performance of MY1510 (+IFM-1) with that of other overseas products. Micronix's radio wave dark box achieves stable shielding performance even with the implementation of interfaces.

[Application Case] Demonstrating the Truth and Lies of Wi-Fi
【Product Introduction】 ■Radio Wave Dark Box / Shield Box Taurus Series MY1530 A large size that accommodates large test objects. A turntable can be installed as an option. When you stop in front of a station in the city and look up, you may see Wi-Fi (wireless LAN) antennas among various antennas on the rooftops of buildings. From what I have observed, it seems that many Wi-Fi antennas are "directional antennas" designed to transmit signals in a specific direction.

【Product Introduction】 ■Handheld Spectrum Analyzer Compact, lightweight, battery-operated (low power consumption), and low cost. Despite being handheld, it offers performance comparable to larger models. ■Anechoic Chamber / Shielded Box Low cost, lightweight, and short delivery time! High-quality, reliable, and cost-effective anechoic chambers and shielded boxes provided by a measurement instrument manufacturer. The anechoic chamber has the following functions, allowing for accurate characteristic measurements of the DUT (Device Under Test): 1. Provides an environment unaffected by external electromagnetic waves. 2. Blocks leakage of electromagnetic waves to the outside. 3. Reduces interference within the anechoic chamber. By leveraging these characteristics and combining them with other measuring instruments and testing evaluation terminals, they can be permanently installed as production line equipment for quality inspection and functional testing of various wireless module-equipped devices (such as wireless LAN and Bluetooth).
[Application Case] Demonstrating the Truth and Lies of Wi-Fi
In the previous installment of this series, it was revealed that in the experiment introduced, it is not the access point (AP) but the terminal side that determines the timing for executing roaming over Wi-Fi (wireless LAN). 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.

There are likely many readers who have the impression that "Wi-Fi (wireless LAN) comes with its share of troubles." I often hear stories like "the connection drops" or "I feel like the Wi-Fi connection got slower when I moved to the conference room with my PC." Among these troubles, what has been on my mind recently is the issue of "the Wi-Fi icon is displayed on the smartphone screen, but there is no connection" or "I moved a little and lost the connection. But it didn't switch to LTE either." These are frustrating troubles that are hard to understand, but they actually occur frequently. There are various causes, and this time I will introduce a case where "differences in signal strength between devices" is a contributing factor. *For more details, please refer to the PDF document or feel free to contact us.

【Product Introduction】 ■Radio Wave Dark 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 microwave ovens 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.
[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. Christmas is just around the corner. Speaking of Christmas, around this time last year (2015), I came across several articles on various websites stating that "Christmas lights could slow down Wi-Fi (wireless LAN)." Tracing back the source of the discussion, it was mentioned in an introduction to a certain Wi-Fi connection verification app as an example of interference, citing "microwaves, baby monitors, and Christmas lights." The interference between microwaves and Wi-Fi is a well-known issue. It is also easy to imagine that baby monitors transmit audio and video using wireless technology. It wouldn't be surprising if other household appliances we commonly use also interfere with wireless LAN signals. However, the idea that "Christmas lights" could cause interference is hard to believe. *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 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 (i.e., expanding the frequency width used) to increase the communication bandwidth, as shown in Figure 1. In particular, with 802.11ac, bonding can be done over 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.
