Our SiWx917 Wi-Fi 6 ultra-low-power wireless MCU can cold boot and SSID scan all channels in about 5 seconds while consuming less than 50mA. The result is fast updates on location without draining the battery. Consider long-life sensors that only wake up when needed. But sensing alone isn’t enough.
The Cloud Knows the Way with our Wi-Fi Asset Tracking Solution
This is where the backend takes over. Once the SiWx917 identifies nearby SSIDs, that data gets pushed to the cloud via MQTT or another protocol. From there, cloud-based mapping, databases, etc. kick in. They match known SSIDs to real-world coordinates, giving you near real-time asset visibility, even indoors.
This backend magic means facilities don’t need to install anything new. Your warehouse, hospital, or factory already has Wi-Fi. That existing infrastructure becomes your positioning system. No proprietary readers. Just the networks already deployed.
We handle the radio; you handle the maps.
That’s the beauty of this solution: it’s collaborative. We provide the silicon and the low-power intelligence. You bring your choice of the cloud, the dashboards, the data insights. Together, it becomes something greater, a full-coverage, multi-technology, fully visible platform that truly optimizes your return on investment of wireless tracker solutions.
You can track a container from factory to forklift. You can follow a medical cart from ICU to storage. You can monitor inventory on the move, through buildings, and blind spots. All using a chip that sips power and slips easily into your existing design.
And if you’re already using GPS and cellular? Great. Wi-Fi doesn’t replace them, it complements them. You can turn off the heavy radios when you don’t need them, hand off to Wi-Fi sniffing when you do. That flexibility is key to optimizing for both coverage and longevity.
Designing a Wi-Fi Asset Tracker: From Possibility to Deployment
We’ve taken this all the way to reference designs. The SiWx917 acts as a controller, working with GNSS, IMU sensors, and MQTT to push data to the cloud. In one of our hybrid builds, smart pallets were equipped with our Wi-Fi SoC to track transit through ships, trucks, and warehouses without ever joining a network. Just sensing. Just sending. Just working.
The logistics company that implemented this deployment was able to add both Bluetooth LE and Wi-Fi with a single chip, extend battery life, and finally get eyes inside their own facilities.
Why Choose SiWx917 to Build a Wi-Fi Asset Tracker?
Easy. In addition to the features and benefits mentioned above, the SiWx917 Wi-Fi 6 ultra-low-power MCU is a fully integrated wireless solution giving you the functionalities and interfaces you need in Wi-Fi trackers. A few examples include:
- Integrated networking stack with TCP/IP, TLS, MQTT, and more simplifies integration with the cloud and location database.
- Includes a rich set of peripherals and GPIO to tie together all the required components such as the GNSS/GPS, LTE/GSM, gyroscope/accelerometer, and an ambient sensor.
- Large SRAM, PSRAM, and flash memory capacity accommodate all necessary firmware, application software, and location data while also leaving room for OTA updates.
- Dedicated application MCU with up to 180MHz and an AI/ML accelerator remove the need for an additional standalone MCU, reducing your BoM, power consumption, and board footprint.
- Wireless and networking stacks are run on a separate processor, increasing MCU sleep time and reducing power consumption.
- Finally, our SiWx917 modules come with an antenna and regulatory certifications, simplifying your RF design and certification work and reducing the development costs and time.
