5 meters – 10 minutes – 5 years
5 years of battery life for indoor tracking system
The batteries in the tags/anchor tags and sensors, used for location data collection, need to last at least five years to ensure that the deployment can reach the desired return on investment (ROI). Even longer battery life can be achieved by using sensor triggered data collection, such as motion, methods or less frequent reporting intervals.
10 minutes interval
For most needs of indoor tracking system, location data is up to date with 10-minute reporting intervals for indoor tracking. In most cases, even 10-, 15- and 30- minute intervals are enough. It is possible to collect the data even more frequently. This will have an effect on the power consumption on the wireless anchors and asset tags.
Most of the time sensor triggered data collection is recommended. The system collects the data when a change in the network happens. Benefits of wireless sensor triggered data collection include:
- Lowers the power consumption
- Decreases the load in data management operations in backend systems.
5 meter accuracy
Use cases in factory production, healthcare, and warehouse spaces require the accuracy of a person’s visual environment which means roughly 5-10-meter accuracy, zone or room accuracy. That is ample enough to reduce the time used in searching for the assets in a large area, like an office building, specialty hospital or a production shop floor.
For assets that require more accuracy, an easy and affordable solution is to add e.g. an LED light to the asset tag, that can be lit to guide to the worker to recognize the asset they are looking for in the area with a 5-meter location accuracy.
Low Total Cost of Ownership
The easy deployment also means lower costs of maintenance. Anyone in the organisation can do the installation and there is no need to hire expensive trade experts to perform the deployment. Wireless anchors also mean zero wirings at the time of installation.
There are ways to lower the TCO per tag per m² per year even more:
- Using our lower cost sensor tags will influence the total price of the tracking and that can keep the price in the lower cents per m² per year for the entire solution, not only the infrastructure.
- When considering the price, also a greater number of tags will lower the price per tag. Volume pricing is key.
- Less frequent reporting will also lower the Total Cost of Ownership of the infrastructure.
Each use case is unique in terms of the needed reporting interval or sensor triggering method, the accuracy, and battery life expectations. The 5-10-5 method acts as a baseline, but to ensure a successful deployment that fits the customers’ requirements, all the points can be altered. Whatever the use case, supply chain logistics, healthcare or manufacturing, the costs will keep in the lower tens of cents per square meter per operational year.
