IoT solutions provider Quectel Wireless Solutions has launched the Quectel KCM0A5S, a high-performance Wi-SUN module designed for smart city applications and street lighting, among other applications.

Based on Silicon Labs EFR32FG25, a sub-GHz low power wireless System on Chip, and featuring an ARM Cortex-M33 processor with a frequency of up to 97.5MHz, the module includes built-in 256KB RAM and 2MB Flash memory, ensuring efficient performance.

The Quectel KCM0A5S supports the Wi-SUN Field Area Network (FAN) 1.1 protocol and operates across the 470–928 MHz frequency range. The module employs IPv6-based wireless mesh networking technology, intrinsic to the Wi-SUN communication standard. It delivers long-range transmission, stable network connectivity and reliable data transmission.

The KCM0A5S also offers flexible deployment capabilities. It supports both router and leaf node configurations in standalone SoC mode, and acts as a border router when paired with a Linux host in RCP (Radio Co-Processor) mode.

The KCM0A5S also features strong anti-interference capabilities and delivers excellent signal penetration which is of specific value for use cases in hard-to-reach locations. With a minimum of ten years product lifecycle and cross-version compatibility, the solution ensures long-term interoperability within Wi-SUN FAN networks.

“We’re delighted to launch the Quectel KCM0A5S Wi-SUN module,” said Delbert Sun, Vice General Manager, Product Department, Quectel Wireless Solutions. “Wi-SUN is a versatile LPWA connectivity technology that is applicable globally to a wide range of use cases. Its security, scalability and robustness provide compelling advantages to developers and device designers and the KCM0A5S adds to this with its ultra-compact form factor, high speed bandwidth and low latency. We look forward to helping customers to build a smarter world with the KCM0A5S as they bring the latest Wi-SUN enabled devices to market.”
