When developing an IoT gadget, weareable, tracker or any other device, there are usually three important factors that will have a big impact in the success or failure of it.
All of them are very closely related. For example:
If we are talking about IoT trackers then the usability fact is directly linked to the location accuracy. These are the main methods of how the location is calculated:
So if you are involved in a real-time asset tracking project, you will probably be wondering how can you have the best accuracy, longest battery duration and lowest cost for a considerable amount of trackers. Well, there is a solution for that:
How can the accuracy of option 3 be improved? Well, a gateway antenna can be placed in the facilities or warehouses to reduce the location error from several kilometers to less than 300 meters. By using this configuration, the cost of each tracker is not increased, the battery duration is not reduced and the location accuracy is improved by a factor of ten.
