4 Essential Questions for Choosing the Right Indoor Positioning Solution

Whether you’re deploying indoor positioning in a hospital, warehouse, construction site, or correctional facility, asking the right questions is crucial to selecting a solution that delivers value, accuracy, and ease of use.

1. What level of accuracy do we actually need?

Start by defining the precision required for your operations. For most facilities—hospitals, factories, correctional centers—room‑level accuracy is sufficient. If your environment demands pinpoint location, such as locating individual items in a sprawling warehouse, you’ll need a system capable of sub‑meter or even centimeter precision.

• Room‑level accuracy: Active RFID or infrared RTLS provide reliable performance for these scenarios.
• Precision (sub‑meter): Ultra‑wide‑band (UWB) or Wi‑Fi‑based RTLS offer the fine granularity you need.

Remember, higher precision often comes with higher costs, so align your accuracy requirement with operational needs.

2. How will the system’s cost impact our budget?

Consider every cost component—installation, tags, access points, and ongoing maintenance. Some systems are prohibitively expensive to retrofit, while others require extensive cabling or permitting.

• Installation: Infrared RTLS demands infrastructure in every room, making it ideal for new construction but costly for retrofits. UWB installation is similarly intensive. Factor in cable runs and permit fees.
• Tag costs: Passive RFID tags can cost pennies in bulk, whereas Wi‑Fi tags may reach $90 each.
• Access points: Active RTLS access points range from $1,000 to $4,500, whereas Wi‑Fi RTLS access points can cost several thousand dollars and require manual calibration, adding labor expenses.

3. What is the required battery life for our tags?

Tag longevity varies by technology. Infrared tags consume power through light transmission, while Wi‑Fi tags are the most power‑hungry and consequently larger.

• Passive RFID stickers: Inexpensive (≈$0.10 each) and battery‑free, but require dense reader placement—often every 10–15 ft—which can be impractical.
• Bluetooth/Active RFID: Standard iBeacon tags cost $2–$10 each and offer a balance between battery life and functionality.
• Infrared & Wi‑Fi tags: Generally larger due to higher power draw; consider your application’s power constraints.

4. Is the user interface intuitive for all stakeholders?

A sophisticated RTLS can overwhelm users if the interface is cluttered. While managers may appreciate detailed maps, frontline staff typically need a straightforward view—perhaps a simple “Where is this shipment?” prompt. Prioritize solutions that balance advanced features with usability.
