In telecommunication, a band – sometimes called a frequency band – is a specific range of frequencies in the radio frequency (RF) spectrum , which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf). Each band has a defined upper and lower frequency limit.
Read moreWhat is frequency band and channel?
A channel is characterized by its bandwidth. Thus, a channel has a starting and ending frequency (also called lower frequency and upper frequency). While frequency generally refers to the number of complete cycles per considered unit of time and is usually a single value. A channel can be wired or wireless.
