ToF – time-of-flight, sometimes called ToA – time-of-arrival.
TDoA – Time difference of arrival.
Both the ToF and TDoA methods rely on measuring the time it takes for the radio waves to travel a certain distance in the air. The difference between ToF and TDoA lies in the distances we actually measure and how we use them to calculate the position of the tag.

Line of sight (LoS) is a type of propagation that can transmit and receive data only in cases where transmit and receive stations are in view of each other without any sort of an obstacle between them. (From Techopedia).
