Renesas offers Sub-GHz wireless communication devices with high RF characteristics and low power consumption. The 860/920MHz band is ideal for applications requiring extensive communication networks, such as smart meters, smart cities, digital signage, and monitoring systems, due to its features such as long-distance communication, bypassing of radio obstacles, and low radio interference with other devices. Renesas has a number of solutions to help customers easily deploy Renesas products, including wireless communication evaluation kits, a Wi-SUN software stack, RF drivers, reference designs, and more.
Sub-GHz Wireless Communications
Sub-GHz wireless communications technology uses radio waves below 1GHz and has the following features compared to Wi-Fi and Bluetooth Low Energy (BLE), which use the 2.4GHz band.
Applications of Sub-GHz Wireless Communication
Wi-SUN Alliance
With the spread of the Internet of Things (IoT), wireless networks are used to relay data back and forth between devices that are equipped with communication functions, and network system complexity and scale are expected to increase. The Wi-SUN Alliance drives the standardization and creation of profiles for communication protocols that can ensure interconnectivity in these diversifying networks. Renesas has been a strong promoter of research and development and international standardization for the Wi-SUN Alliance since its establishment and develops solutions that support the protocols of the Wi-SUN Alliance.
Starter Kits
These evaluation boards have been certified for technical standard conformance for Japan and CE certification for the European Union, and are used by the Certified Test Bed Unit (CTBU) authorized by the Wi-SUN Alliance.
