High Quality Content by WIKIPEDIA articles! Radiolocating is the process of finding the location of something through the use of radio waves. It generally refers to passive uses, particularly radar — as well as detecting buried cables, water mains, and other public utilities. It is similar to radionavigation, but radiolocation usually refers to passively finding a distant object rather than actively one's own position. Both are types of radiodetermination. Radiolocation is also used in Real Time Locating Systems (RTLS) for tracking valuable assets. An object can be located by measuring the characteristics of received radio waves. The radio waves may be transmitted by the object to be located, or they may be backscattered waves (as in radar or passive RFID). The received signal strength (RSSI) may be used to estimate distance if the transmitted power and dependence of signal strength on distance is known. The time of arrival (TOA) can provide a distance estimate if the time of transmission and speed of propagation are known.
