Technical Column - What is the new Wi-Fi standard IEEE 802.11ah (Wi-Fi HaLow) suitable for long distances?

IEEE 802.11ah compatible wireless LAN converter

This product is a compact IEEE802.11ah compatible wireless LAN converter. It complies with the standard IEEE802.11ah, allowing for the construction of a high-speed and long-range network. It supports external antennas, enabling the creation of a flexible wireless LAN system, and its lightweight and compact design allows for various installations such as on walls or DIN rails using the included mounting bracket. Additionally, it can be used as an access point (parent station) that can connect to up to four stations (child stations) by switching modes. 【Main Features】 ● Compliant with IEEE802.11ah standard ● Supports 920MHz band wireless with excellent transmission distance ● High-speed communication capable of video transmission ● Switchable between station (child station) and access point (parent station) ● Compatible with various power supply options and a wide temperature range

• Wireless LAN

A Wi-Fi wireless access point that can cover several hundred devices (theoretical value) within a radius of 1 km and can connect to equipment from different manufacturers.

This product is a compactly designed IEEE802.11ah compliant wireless access point that can be used in various installation locations. The new Wi-Fi standard "IEEE802.11ah," which utilizes sub-gigahertz wireless communication, became available in Japan in September 2022. It operates in the 920MHz band, allowing for outdoor use without a license. Compared to traditional 920MHz wireless communication, it enables high-speed communication and the establishment of long-distance networks, making it promising for use in large factories, plants, and farms. The wireless access point of this product can be installed in various locations, including walls and DIN rails, thanks to its compact design and included mounting bracket. It also supports external antennas, allowing for the construction of a highly flexible wireless LAN system. 【Main Features】 ● Compliant with IEEE802.11ah standard ● Supports 920MHz band wireless with excellent transmission distance ● Compatible with various power environments and mode switching ● Suitable for installation not only on flat surfaces but also on walls and DIN rails ● Supports a wide range of temperature environments ● Compliant with advanced security standards WPA3/WPA2

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
