Write 5 pages thesis on the topic tracking technology. Radio Frequency Identification (RFID) is applied in various instances. RFID technology consists of a tag that has a transmitting antenna that can disburse and receive radio signals. The broadcast information used for communication is found in a chip. There are active and passive tags in this technology, which are differentiated from the method of broadcasting power used. This mode of tracking can be used to tell the direction and range of a tracked object.
The Global Positioning System (GPS) is a more advanced tool in terms of reporting the location of an object. The GPS tracker has a receiver that determines the position of an object. It also has an embedded mechanism that reports the data obtained. Information is conveyed through radio transmission or cellular networks. Wide area systems require satellite receivers for extended worldwide reach. The technology is more efficient as compared to RFID as it can tell the exact position of an object/person from a wide range. It is, however, more expensive.
Geofencing is a technology that uses RFID or GPS, and confines its reporting to a particular passive state. The technology, while applying RFID, senses proximity to a radio scanner and detects an object’s location through GPS. The technique is preferred on a passive area and alerts the user once the subject leaves a certain confined area. In areas served with wireless networks, it is possible to use wireless positioning systems. The position of an object is then accessed using a MAC address and the “received signal strength”.
Tracking of people has raised considerable debate on ethics and privacy. There are cases where the tracking technologies are used by individuals to abuse the rights of other individuals. Such instances include stalking by spies, lovers, or just technology savvy individuals wanting to test their equipment. .
