FAQ Section

Addressing common questions about RTLS.

Q: How long does a tag’s battery last?

A: Battery consumption is a matter of the radio technology and amount of communication that takes place. Wi-Fi for example takes a heavier toll on batteries than Bluetooth Low Energy (BLE). The communication requirements of a tag vary by use case. For example, to track a Wi-Fi tag that updates every 3 seconds might require recharging every couple of days. On the other hand, a BLE tag that chirps every couple of minutes might last 5 or more years.

Q: How much do RTLS tags cost?

A: Thanks to the consumerization of BLE chips, a simple BLE tag can cost several dollars ($US). Tags that support multiple radio technologies and types of interfaces can cost upward of $100.

Q: What accuracy can I expect with an RTLS solution?

A: Using the wireless access points in your environment and Wi-Fi tags, you can expect roughly 5-7 meters of accuracy. AiRISTA improves on this using a radio frequency (RF) fingerprinting technique that increases accuracy to 3-5 meters. Augmenting the access points with small radios installed nearer the tags will improve accuracy to under 3 meters. New BLE technology, like the angle of arrival, has been introduced which provides submeter accuracy.

Q: Can RTLS track tags in the vertical dimension?

A: Newer technology like BLE angle of arrival has the additional benefit of being able to track tags in the X, Y, and Z dimensions.

Q: What is the difference between location and proximity?

A: Location provides a position on a map (think of an X, Y coordinate). This is useful when you want to know where within an area a tag is. Location is determined when 3 or more reference points like access points detect the tag. Algorithms using triangulation are used to determine the position. Proximity is simply a measure of how near a tag is to a device like an access point or other detector. Since there is only one device detecting the tag, there is no sense of left, right, forward, or back. Proximity is useful for detecting when a tag passes a specific spot like a doorway. 

Q: What is the role of the RTLS software platform?

A: Analysts like Gartner encourage customers to consider the ability of the RTLS software solution to provide a platform for location insights across the enterprise. The RTLS software platform collects signal information from hundreds and thousands of tags. Using that information, it uses a number of algorithms to determine each tag’s location. The software manages the maps on which the locations are positioned. The platform facilitates rules that alert to changes in the locations and conditions of tags. But to be a true platform, the software needs to scale across the enterprise, not only in terms of compute capability but in terms of its support for a wide range of use cases. As a platform, it must also support a broad range of technologies that apply the right level of location accuracy at an appropriate cost. Finally, to derive the most value from the RTLS platform the software must readily integrate with the other applications in the enterprise that drive workflows and continuous operation. 

Q: What are the pros and cons of RFID and RTLS?

A: RFID tags are typically a couple $USD or less and require no batteries. However to be energized they require “RFID readers” positioned nearby. The location of each reader is used to infer the location of the tag. The readers typically provide proximity and are positioned at choke points like doorways. RTLS, on the other hand, uses tags that cost under $10 USD to over $100 depending on the sophistication. Battery maintenance should be considered. RTLS solutions provide a near continuous x,y position in near real time.
