**Unlocking Indoor Visibility: Wi-Fi Asset Tracking Without Connecting**

Imagine a pallet loaded with high-value goods on its way across continents. You track it with GPS and cellular — but once it arrives at a warehouse, all visibility fades. Why? Because GPS doesn’t work through walls, and cellular positioning often loses precision indoors. The asset is still there — but, digitally, it's gone dark.

Silicon Labs offers a compelling solution: **Wi-Fi-based asset tracking without ever connecting to a network**. Instead of joining a Wi-Fi network, devices simply *listen* — scanning for nearby SSIDs (network names) and measuring their signal strength to infer location.

**What Makes This Approach Powerful**

- **No network handshakes.** There’s no need to associate with an AP. The device just senses.
- **Ultra-low power consumption.** Using the SiWx917 Wi-Fi 6 wireless MCU, the device can cold boot and scan all channels in roughly 5 seconds while drawing under 50 mA.
- **Leverages existing infrastructure.** Your warehouse or facility’s current Wi-Fi becomes a “virtual positioning system” — no extra hardware needed.
- **Cloud integration.** Once SSIDs are detected, the SiWx917 sends the data to the cloud (via MQTT or other protocols). The backend maps SSIDs to real-world coordinates.
- **Multi-tech synergy.** This Wi-Fi sensing can complement GPS, cellular, or other radios — switching dynamically depending on where the asset is.

**How to Build a Real Device**

Silicon Labs has already created **reference designs** using the SiWx917. In these designs, the MCU works with:

- **GNSS/GPS module** for long-range outdoor tracking
- **IMU sensors** (accelerometer/gyro) to monitor movement
- **MQTT cloud stack** to report location data

In one real-world case, a logistics firm embedded this into smart pallets. The result? They gained continuous visibility — from the factory, onto trucks and ships, into the warehouse — without compromising battery life.  

**Why the SiWx917 Is a Game-Changer**

Here’s why this MCU is particularly suited for passive Wi-Fi tracking:

- Fully integrated: Wi-Fi 6 radio + application MCU + AI/ML accelerator → smaller BOM.
- Rich connectivity: TCP/IP, TLS, MQTT stacks built-in → smooth cloud integration.
- Memory & processing: Generous SRAM, PSRAM, and Flash for firmware, OTA, and tracking logic.
- Low-power architecture: Separate network and application processors let the MCU sleep more, reducing power use.

Certified modules: Pre-certified modules include antenna and regulatory approvals → easier design and faster time to market. 

**Real-World Applications**

This connectionless Wi-Fi tracking opens up many practical use cases:

- **Logistics & supply chain:** Track pallets or containers inside warehouses without deploying extra trackers or gateways.
- **Healthcare:** Follow equipment (e.g., carts, IV stands) inside hospitals, where Wi-Fi is already ubiquitous.

**Industrial automation:** Monitor tools, vehicles, or resources as they move through production facilities. 

**How We Can Help**

As an **official Silicon Labs distributor**, we can support your project from design to deployment:

- Provide you with **SiWx917 development kits** and modules for testing
- Help connect you with **Silicon Labs technical support** to build your tracking architecture
- Assist with **product selection**, certification, and supply chain integration

For instance:

- **Silicon Labs SiWx917 Wi‑Fi 6 Dev Kit** — ideal for prototyping your tracker.
- **Silicon Labs WFM200S022 Wi‑Fi Module** — a compact, certified Wi-Fi module for embedded designs.

**Conclusion**

Wi-Fi asset tracking without connection is a paradigm shift. Instead of demanding new infrastructure or draining power with constant network participation, you simply *listen* — and let existing Wi-Fi networks do the heavy lifting. Thanks to the efficiency and flexibility of the SiWx917, this becomes not just a concept, but a practical, deployable solution.
