RFID or radio frequency identification is now being used in several industries. Radio Frequency Identification (RFID) is a thermal and drying processing method based on the absorption of radiofrequency energy within the item. Unlike conventional techniques, wherein heat is transmitted to the item via its surface by conduction, heating or convection, radiofrequency energy directly within the material is emitted by radiofrequency technology. Hence, radio frequency-based technology uses radiofrequency energy to precisely identify and catalogue items.
- RFID uses radiofrequency technology to locate, personalize and track inventory items. Radiofrequency technology also allows for the super fast recording and retrieval of data. This superfast retrieval and recording capabilities of radio frequency technology have made it a boon to the medical and healthcare industries. The medical industry is now using radiofrequency technology to remotely diagnose, monitor and manage patients with all the latest in healthcare information at hand.
- RFID is also increasingly used in the military, law enforcement and emergency services for several applications. Radio frequency technology has also found extensive use in the commercial and industrial sectors, particularly for environmental monitoring, personal and protective applications and controlling access to hazardous environments. It has now become essential for companies managing hazardous and other environmental environments to implement Radio Frequency Identification (red) to ensure compliance with the various national and international regulatory bodies that require such systems to mitigate adverse effects of potential hazards may have on staff and/or the environment. Such systems are now required by law to be positioned in strategic positions to observe and report on hazardous conditions. Thus, radiofrequency technology has provided essential services to our society in areas that were previously not able to utilize them due to the inaccessibility of RFID systems in such locations. The following article provides further information on the benefits of Radio Frequency Identification (red) and its usage in the commercial and industrial sectors:
RFID provides a cost-effective means to track and identify objects by measuring their radio frequency emissions as emitted by the objects. The emission patterns are then decoded by transistors based on mathematical algorithms to yield detailed information. Radiofrequency technology uses two main transistors – a power transistor and an antenna. The power transistor is the key component of radiofrequency technology, which generates the radio frequency signals necessary to capture and track objects. The antenna is the physical component that receives and measures radio frequency emissions from the objects being tracked.
The principle of utilizing radio frequency technology for tracking human exposure is based on the understanding that radiofrequency emissions are inherently dangerous if not monitored. A low power radio frequency signal emitted from a power transistor can reduce human tissue temperature (HFD) up to temperatures as high as 100oF. Additionally, power transistors can only tolerate a certain amount of human tissue temperature at any one time. When a system fails to monitor and measure human exposure, adverse biological effects may occur.
One particular HFD is based on a mathematical equation which expresses electrical energy which emits high-frequency radio waves as the power input into a power transistor. The equation states that the power input will equal the voltage change that occurs when that particular transistor is energized. This equation can be used as a guide to determining the power output voltage change which results in radio frequency output voltage. The measured output current is typically in watts (W), which is an electrical measurement that indicates the power measured over a length of time. In the context of this application, the measurement of the radio frequency output power is referred to as RFID efficiency or RFID measurement.
The power output voltage changes as a function of frequency and the distance between power sources is called RFID bandwidth. A low bandwidth radio wave output will result in a lower measurement capability. The distance between radiofrequency sources can have a significant impact on the measurement of radio wave power. Radio Frequency Identification, also known as RFID, is an industry-standard way to ensure compliance with radio wave emission limits, cost of operation and overall integrity of the operation and maintenance of supply chain systems.
The use of radiofrequency technology in many applications has resulted in improvements in product life-cycle costs, decreased maintenance and service costs, improved access to vital information for customer care, and increased availability of parts and services. The ability to remotely control digital devices and process data for optimal recovery has resulted in the increased productivity of operators, cost savings in support and repair services, and improvement in employee safety. This type of remote control technology is not limited to applications in health care and industrial environments but has considerable potential for becoming a widely used tool in many other fields as well. RFID software and hardware advancements are not far away from truly widespread implementation in all areas of the business world.
