In a construction area short before opening to the public we actually train our skills to locate a person based on Last Living Location LLL. As the time frame is limited for 72 hours we have to focus on speed and efficiency. After a first test run we faced problems by reflection of RF signals which brought us to the question
How can RF reflections be fast discovered? As a location can be obtained by direct and indirect RF measurement (but not visible) how to know exactly where the signal came from? Directional receiver antennas we have but the grade of complexity is very difficult.
Who has a new approach to learn from for allspace (indoor+outdoor=alldoor+underground=allspace) location finding?
BTW we tested the Google Tango functionality but at the time not really helpful. 3D-laser still top but not easy moving mobile.
Please share your experience. Thank you.
