By the end, you’ll understand why industrial IoT platform spending on location positioning infrastructure is projected to grow at 29% CAGR to reach $10B by 2028.

The Basics: How Real-Time Location Systems Work

Real-time location systems provide precise tracking of people and objects by processing data from tags, anchors and sensors through advanced location software engines.

Tags are devices that attach to assets and transmit encoded location signals using RF technologies like Bluetooth, Wi-Fi, UWB or RFID.

Strategically placed anchors pick up these location signals, timestamp them and relay the data to location engines.

Sophisticated algorithms in the location engine analyze the different time-based data points to accurately calculate X/Y/Z coordinates relative to the anchors, providing updates on tag locations in real-time.

Unlike GPS which requires line-of-sight, RTLS leverages sensors and unique RF signals allowing location tracking indoors where obstacles like walls and inventory can make triangulation difficult.

Now let‘s explore the two most impactful applications taking advantage of these advances.

Key Application #1: Indoor Location Tracking

Fixing location tags to key personnel, products and assets provides a live view into positioning as items move within buildings and defined areas. Industrial and retail companies are using real-time indoor tracking across their facilities to:

• Optimize picking/put-away workflows
• Ensure regulatory compliance
• Reduce equipment search/rental costs
• Manage inventory accurately
• Gain customer behavior insights

Walmart shared impressive results after piloting an RTLS system in 16 stores for inventory management by tagging high-value goods like electronics. They saw:

• 30-60% improvement in inventory accuracy for items tracked
• 20-30% increase in item availability for purchase
• 25%+ reduction in missing item search times

With even more minor gains across their full fleet of 4700 stores, Walmart could generate tens of millions in cost savings and revenue.

Cisco‘s enterprise-grade location services platform enables customers like Schneider Electric to track over 50,000 tools and equipment across 8 manufacturing centers. Results included:

• 20% reduction in asset search times
• >90% accuracy in tool tracking
• 15% increase in tool usage

Location data provides visibility to optimize asset usage while minimizing losses.

Key Application #2: Geofencing

While understanding precise coordinates helps warehouse workflows, retail apps and hospital asset management, sometimes location specifics don‘t matter. Often, you just need to define areas of interest and know when something enters or leaves that zone.

Geofencing leverages location sensors and virtual boundaries for zone-based alerts, no matter the exact positioning within the area.

Common use cases:

• Patient Wandering Prevention: Tags worn by dementia patients trigger alerts if they wander out of safe units
• Asset Loss Prevention: Shipping & storage sites monitor when high-value items leave or bypass assigned zones
• Workflow Notifications: Hospital staff get alerts when key equipment like crash carts are moved beyond expected operating vicinity

Market researcher Gartner estimates that 70% of asset management solutions will leverage geofencing for indoor/outdoor use cases by 2025, equating to a $9B market potential. Their data shows geofencing delivering significant ROI across sectors:
