A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
From Tables 5.5-1 "E-UTRA Operating Bands" and 5.6.1-1 "E-UTRA Channel Bandwidth" of the latest published version of the 3GPP TS 36.101, [1] the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports.
When distributing initial spectrum licenses in a band the FCC divides the US geographically into a number of areas. [1] A mobile operator (or other interested party) must bid on each area individually. A license owner can use any technology within the licensed area and frequency range subject only to the band rules defining various analog limits.
For telecommunications, a frequency grid is a table of all the central frequencies (and corresponding wavelengths) of channels allowed in a communications system.. The most common frequency grid used for fiber-optic communication is that used for channel spacing in Dense Wavelength Division Multiplexing (DWDM) at wavelengths around 1550 nm and defined by ITU-T G.694.1.

Spectral bands have constant density, and when the bands overlap, the corresponding densities are added. Band spectra is the name given to a group of lines that are closely spaced and arranged in a regular sequence that appears to be a band. It is a colored band, separated by dark spaces on the two sides and arranged in a regular sequence.
Cub Scouts is a Scouting America program available to coeducational children from kindergarten through fifth grade (or 5 to 10 years of age) and their families. Its membership is the largest of the five main Scouting America divisions (Cub Scouting, Scouts BSA, Venturing, Exploring and Sea Scouting).
Wireless Communications Service (WCS) is a set of frequency bands designated in the United States and Canada in the 2305–2320 and 2345–2360 MHz spectrum range. The most common use of WCS spectrum is mobile voice and data services, including cell phone, text messaging, and Internet. [1] There are four blocks in WCS: [1]
The 1090 MHz frequency (paired with 1030 MHz) is also used by Mode S transponders, which ADS-B augments when operated at this frequency. The TCAS system also utilizes the 1030/1090 MHz paired frequencies. ADS-B information can also be broadcast on the L band frequency of 978 MHz. DME and TACAN systems are also in this frequency band.
