Radio spectrum is the part of the electromagnetic spectrum ranging from 1 Hz to 3000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, have become widely used in modern technology, particularly in telecommunication.
Read moreIs radio frequency a radar?
Radars usually operate at radio frequencies (RF) between 300 MHz and 15 GHz . They generate EMFs that are called RF fields. RF fields within this part of the electromagnetic spectrum are known to interact differently with human body.
Read moreWhat is the frequency range of VHF radar?
The UHF and VHF radars typically operate in the frequency range from the low VHF band (40–50 MHz ) to the upper UHF band (3 GHz).
Read moreWhat two frequency bands do wireless LANS use?
WLAN technology transmits information in space by using radio waves on the 2.4GHz and 5GHz frequency bands.
Read moreWhat are HF ham frequencies?
Typically this can be 3.5 – 3.8 MHz , although in North America, frequencies up to 4.0 MHz can be used, although there is a broadcast band allocation above 3.8 MHz. This ham radio band can be quite noisy, especially at night as it is shared with other services and this can make it very busy.
Read moreWhat HF frequency is best?
HF users have found that using a frequency that is the MUF times 0.85 gives the best chance for good results. This is called the frequency of optimum transmission (FOT).
Read moreWhat frequencies are in the HF band?
High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz . Much of the HF band is allocated to mobile and fixed voice communication services requiring transmission bandwidths of less than 12 kilohertz.
