As a matter of convention, the ITU divides the radio spectrum into 12 bands, each beginning at a wavelength which is a power of ten (10 n) metres, with corresponding frequency of 3×10 8−n hertz, and each covering a decade of frequency or wavelength. Each of these bands has a traditional name.

2023年6月5日 · Being aware of HAM radio frequencies & Bands is an essential part of your journey of becoming a successful ham radio operator. Here in this article I’ve tried to compile all information regarding Ham radio frequencies and bands that are allocated by the FCC.

The official FCC Table of Frequency Allocations is the one published in the Federal Register. The text of footnotes has not been included in this chart but is available on the FCC's website.

2018年2月22日 · The ISM frequency allocation includes several frequency bands, including: 13.56 MHz: This band is used for near-field communication (NFC) and radio-frequency identification (RFID) applications. 433 MHz: This band is used for a variety of applications, including remote control devices, wireless sensors, and alarm systems.

Currently only frequency bands between 8.3 kHz and 275 GHz have been allocated (i.e., designated for use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions). OET maintains the FCC's Table of Frequency Allocations, which is a compilation of allocations.

For the allocation of frequencies the ITU has divided the world into three Regions. Click here to view a PDF map of the three Regions. The general rules for reading the Table are: Primary services are printed in "capitals;" e.g., FIXED. Secondary services are printed in "sentence case or normal characters;" e.g., Mobile.

Guide to RF Band Nomenclature This chart provides a rough guide to typical RF band nomenclature in engineering. There are numerous standards, some of which conflict in common usage. Originally, most RF bands were designated by wavelength in free space, referenced by decade. For example, low-frequency (or simply LF), refered to
