Radio frequency range which is at 3KHz to 300 MHz, Microwave which is at 300MHz to 300GHz, and Infrared is at 300GHz to 400 THz.
One frequency that is not commonly used for wireless communications is the extremely low frequency (ELF) range, typically below 3 Hz. This range is unsuitable for conventional wireless communication due to its long wavelength, which requires impractically large antennas and is primarily used for specialized applications like submarine communication. In contrast, frequencies in the megahertz (MHz) and gigahertz (GHz) ranges are widely used for various wireless communication technologies.
What are the frequency ranges included in the following frequency subdivisions? MF, HF, VHF, UHF and SHF
The L band frequency ranges from 1 to 2 GHz. It is commonly used for satellite communications, GPS systems, and aviation navigation. Its longer wavelength allows for better penetration through obstacles like buildings and vegetation compared to higher frequency bands.
The high band of VHF (Very High Frequency) ranges from 174 to 216 MHz. This portion of the VHF spectrum is primarily used for television broadcasting, as well as some radio communications and public service frequencies. It provides better transmission characteristics and is less susceptible to interference compared to lower frequency bands. High VHF is also utilized for various wireless microphones and other audio equipment.
There is signal loss, over distance for any wireless (Radio) system. The cellular system gets over this problem, by using only short ranges between cells. A cell phone swaps signal, from one cell to another and changes frequency automatically.
12-14ghz
Radio signals are broadcast in kilohertz (kHz) and megahertz (MHz) because these units effectively represent the frequencies used for various communication purposes. Kilohertz typically covers lower frequency ranges, suitable for AM radio and certain communication systems, while megahertz encompasses higher frequencies used for FM radio, television, and other wireless communications. These frequency ranges allow for efficient transmission and reception of signals over varying distances and conditions. Additionally, using standardized units like kHz and MHz facilitates easier communication and coordination among different broadcasting services.
The frequency of infrared radiation ranges from about 300 GHz to 400 THz.
The frequency of a busy tone typically ranges from 480 Hz to 620 Hz.

The frequency range of a cymbal typically ranges from 1,000 Hz to 5,000 Hz.
Yes, a wireless n adapter is backwards compatible with wireless g. Check the box you are buying and it will tell you if it is compatible with which wireless ranges.
