Detection and reporting techniques for collisions between transmitters of two different radio access technologies (RATs) transmitting in a shared radio frequency spectrum band is described. The collision may occur following a listen-before-talk procedure but prior to transmission of data, and may not ...
The International telecommunications Union, ITU frequency bands define a set of portions of the radio frequency spectrum: VLF, LF, HF, VHF, UHF, EHF, etc .
Radio frequency bands spread in the range between 30 kHz and 300 GHz. Numerous applications exist for this diapason of electromagnetic spectrum.
Before 1930 the radio spectrum above 30 megahertz was virtually empty of man-made signals. Today, civilian radio signals populate the radio spectrum in eight frequency bands, ranging from very low frequency (VLF), starting at 3 kilohertz, and extending to extremely high frequency (EHF),… Read ...
Common radio frequency bands include the following: AM radio: 535 kilohertz to 1.7 megahertz Shortwave radio: bands from 5.95 megahertz to 26.10 megahertz Citizens band (CB) radio: 26.965 megahertz to 27.405 megahertz Television stations: 54 to 88 megahertz for channels 2 through 6 FM radio: 88...
The radio frequency spectrum includes the set of frequencies of the electromagnetic framework ranging from 30 Hz to 300 GHz. It is divided into several ranges, or bands, and given labels, such as low frequency (LF), medium frequency (MF) and high frequency (HF), for easier identification. ...
Methods, systems, and devices for wireless communications are described where a system bandwidth within a shared radio frequency spectrum band may be divided into multiple sub-bands. A base station may use a fallback downlink control information format to provide a resource grant to a user equipmen...

The frequencies falling between 3000 hertz (3 kHz) and 300,000,000,000 hertz (300 GHz) are calledRADIO FREQUENCIES(abbreviated rf) since they are commonly used in radio communications. This part of the radiofrequencyspectrum is divided into bands, each band being 10 times higher in frequency ...
