Contec Introduces the RP-WAH-SR12 and RP-WAH-SR22 Ethernet Wireless Converters

Contec, based in Nishiyodogawa, Osaka, has unveiled a groundbreaking product designed to enhance long-distance wireless communication— the Ethernet wireless converters RP-WAH-SR12 and RP-WAH-SR22. Available starting August 21, 2025, these innovative devices are built to leverage the 920MHz sub-giga band, utilizing the IEEE 802.11ah standard to enable Ethernet communication over distances of up to 1 kilometer.

The RP-WAH-SR12 is tailored for long-distance transmission, whereas the RP-WAH-SR22 offers a compact design suitable for a variety of installations. Both models are versatile, compact, and equipped with features that make them ideal for various environments including expansive factories, plants, and farms.

Key Features of the New Products

Compliance with IEEE 802.11ah Standard

The converters utilize the 920MHz sub-giga band for wireless communication, which effectively minimizes interference experienced with traditional wireless LAN products operating at 2.4GHz, 5GHz, or 6GHz. Enhanced wall penetration and the capability to navigate obstacles improve long-distance connectivity. Additionally, the converters support advanced security standards like WPA3/WPA2, ensuring robust protection for data transmissions.

Outstanding Transmission Distance

The 920MHz band is noted for its excellent radio wave propagation characteristics, enabling transmission distances of approximately 1 km even in environments with obstacles. This technology allows for consistent and reliable communication, making it suitable for areas where maintaining network stability is critical.

High-Speed Data Transmission

These converters can facilitate high-speed data transmission ranging from 150Kbps to 13.5Mbps, with practical use cases expecting speeds around 1Mbps. This capability opens up new possibilities for wireless connections in remote locations, including visual surveillance tasks that were previously challenging.

Flexible Mode Switching

The devices can be configured as either access points (parent stations) or as child stations, allowing for seamless integration within existing networks. An access point can connect up to ten child stations, offering flexibility in network design and scalability.

Diverse Power Supply Options

The converters can be powered through various means, including an AC adapter (sold separately), a direct current supply ranging from 8 to 35VDC, or USB power. They can operate in a wide range of environmental temperatures, from -20°C to 60°C, making them adaptable to both cold and hot conditions.

Expected Applications

With these features, the RP-WAH-SR12 and RP-WAH-SR22 are poised to revolutionize industries where long-distance wireless communication is essential. For instance, farms can utilize these devices to extend their network coverage across vast areas, while factories can ensure that all machinery remains interconnected without a significant loss of signal strength.

Conclusion

Contec is committed to pioneering industrial technology, having built a legacy of innovation since its establishment in 1975. The introduction of the RP-WAH-SR12 and RP-WAH-SR22 models is a testament to its ongoing dedication to providing advanced solutions that meet the ever-evolving needs of various industries. By harnessing cutting-edge technology, Contec continues to enhance connectivity and productivity across diverse fields.
