Quectel Wireless Solutions, a global provider of IoT Solutions, launched the Quectel KCM0A5S, a high-performance Wi-Sun module that was developed for intelligent applications such as street lighting, precision agriculture, industrial IoT, smart measuring devices and smart cities.

Based on Silicon Labs EFR32FG25, a sub-GHz-wireless system with low power consumption and an ARM-Cortex M33 processor with a frequency of up to 97.5 MHz, the module includes an integrated 256 kB RAM and 2 MB flash memory, which ensure efficient performance.

The Quectel KCM0A5S Supports the Wi-Sun field area network (Fan) 1.1 Protocol and works over the frequency range of 470–928 ​​MHz. The module uses the IPV6-based wireless network network technology, which is intrinsic to the Wi-Sun Communication standard to provide long-term transmission, stable network connectivity and reliable data transmission. In addition, the KCM0A5S offers flexible provision functions that support both router and leaf node configurations in independent SOC mode and act as a border router if they are paired with a Linux host in RCP mode (Radio Co-Processor). This versatility makes it an ideal solution for a wide range of network applications in smart city, benefits and industrial IoT deployments.

In addition, the KCM0A5S has strong anti-interference functions and offers excellent signal inflation that is difficult to achieve for use cases. With at least ten years of product life cycle and cross version compatibility, the solution ensures long-term interoperability in Wi-Sun fan networks.

“We look forward to starting 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 worldwide for a wide range of applications. Its safety, scalability and robustness offer developers and device designs convincing advantages, and the KCM0A5S help with the ultra-compatible form factor with high speed range and low latency. capable devices on the market.

The flexibility for developers and designers is secured thanks to the Ultra Compact LCC form factor of the KCM0A5S-LCC-Form factor. Dimensions of 28.0 mm x 22.0 mm x 3.15 mm enable the size and costs for optimized end products, which enables maximized design options. The module is also ideal for use cases in industrial quality with an operating temperature range from -40 ° C to +85 ° C. The module is available in variants that support a top transmission performance of 30 dBM – which is currently permitted in selected regions such as North America, Latin America and some APAC countries – and offers both OFDM and FSK modulation, the regional regulatory allowances are available.

Due to its connectivity solution (Low Power Wide Area), Wi-Sun has gained the connection of IoT devices as a solution with low performance (low power wide area) because scalability, security, interoperability and performance mix. It offers a high -speed bandwidth of up to 2.4 Mbit / s with OFDM modulation. The technology is easy to expand and can support thousands of nodes. The self-forming and self-healing network of Wi-Sun eliminates a single point of the error networks and simplifies the provision.

The combination of far-reaching coverage, long-distance distances in several kilometers and the ability to serve urban scenarios that are covered in multi-hop mode Wi-Sun for intelligent measurement and smart city applications taken over. For example, a tax management system for road lighting, supply companies and parking spaces was used in London, which uses 15,000 Wi-Sun devices and 12 Wi-Sun border routers to enable remote management in real time and to provide a future-proof system that can be scaled as city crossings for the new infrastructure.
