In mines the companies have a system to detect workers inside the mine, with Gps an others expensive technology. Is possible with ibeacon to detect when people get inside and when they get out the mine?. Also know who are each workers, and in what position are they working?. This can be a better way, beacuse gps and other possibilities are expensive and doesnt work well inside a mine.
It's a question about specific use case, technically it's possible but it depends on several factors so I would recemmend you to contact our business team email@example.com I believe they can give you more details about implementation.
