What is Radio Frequency Technology?
RF technology is used in many different applications, such as television, radio, cellular phones, radar, and automatic identification systems. The term RFID (radio frequency identification) describes the use of radio frequency signals to provide automatic identification of items. RFID is used in applications such as: Electronic toll collection (ETC ) Railway car identification and tracking Intermodal container identification Asset identification and tracking Item management for retail, health care, and logistics applications Access control Animal identification Fuel dispensing loyalty programs – Automobile immobilizing (security) Radio frequency (RF) refers to electromagnetic waves that have a wavelength suited for use in radio communication. Radio waves are classified by their frequencies, which are expressed in kilohertz, megahertz, or gigahertz. Radio frequencies range from very low frequency (VLF), which has a range of 10 to 30 kHz, to extremely high frequency (EHF), which has a ra
