High frequency (HF) is an electromagnetic frequency defined by the International Telecommunications Union (ITU) for radar and radio communications. It operates in a range of three to thirty MHz and as the wavelengths spread over ten to one hundred meters, it is also known as decameter wave and...

RFID, which stands for radio frequency identification, is a form of wireless communication that uses radio waves to identify and track objects. There are a number of forms of RFID technology on the market today. The most recognizable include low frequency (LF), high frequency (HF), and ultra...

5G provides peak speeds as high as 10 gigabits per second (Gbps) for downloads. 5G can operate on low frequencies (below 6 GHz), as well as HF ranges, commonly known asmillimeter waves, orMM waves(higher than 6 GHz). The higher the frequency, the more likely the user is to experien...

RFID tags use different frequencies to communicate with the reader. The most common RFID frequencies are low frequency (LF), high frequency (HF), and ultra-high frequency (UHF). LF tags have a shorter range than HF and UHF tags. The range of an LF tag is typically between 3 cm and 10...
When high-frequency EM fields encounter obstacles in their direction of propagation, they might get absorbed or reflected. The material characteristics of the object have a specific role. They are important in determining which mechanism is dominant. As a result, the transmission of HF fields in ...
One key safety consideration in HFW is the radiation of high-frequency (HF) fields from the welding machine.Generally,machines with visible open electrodes, which are unshielded, tend to emit stronger fields than those with enclosed electrodes.However,the strength of the field diminishes sharply with...
