While traditional GPS can provide real-time location information for assets anywhere in the world, it is inaccurate within a range of 5 to 20 meters, making it impractical for indoor environments. RFID offers high accuracy but has limited range, requiring the use of thousands of receiver tags in large facilities. Among other RTLS technologies, including Wi-Fi, each has its own advantages and disadvantages.
Therefore, when selecting an RTLS for your facility, consider the following:
• Targets: Are you tracking people, assets, or both? Will you track them through wearable tags or mobile devices? How many devices do you intend to track?
• Accuracy: How accurate does your RTLS need to be? Is it sufficient to know if an asset is in a specific area, or do you need the precise location of the asset within 1 meter or less?
• Latency: How real-time does your tracking need to be? Can you set a latency requirement of 10-20 seconds to align with your needs, or do you require greater accuracy?
