RFpõhised

RFpõhised is an Estonian term that translates to "RF-based" in English. It refers to technologies, systems, or methods that utilize radio frequencies (RF) for their operation. Radio frequencies are a part of the electromagnetic spectrum, typically ranging from about 3 kilohertz to 300 gigahertz, and are used for a wide array of applications.

In the context of technology, RFpõhised systems are common in wireless communication. This includes technologies like Wi-Fi, Bluetooth, cellular networks (2G, 3G, 4G, 5G), radio and television broadcasting, and radar systems. These systems transmit and receive information by modulating radio waves, which travel through the air or vacuum. The specific frequency used often dictates the capabilities and limitations of the technology, such as bandwidth, range, and penetration through obstacles.

Beyond communication, RFpõhised principles are also applied in other fields. For instance, radio-frequency identification (RFID) uses RF waves to identify and track tags attached to objects. Medical applications include MRI (Magnetic Resonance Imaging), which uses RF pulses to create detailed images of the body. Industrial applications can involve RF heating for processes like drying or curing. The widespread use of RFpõhised technologies underscores their importance in modern infrastructure and daily life.
