 (bănd′wĭdth′, -wĭth′)
1. The numerical difference between the upper and lower frequencies of a band of electromagnetic radiation, especially an assigned range of radio frequencies.
2. The amount of data that can be passed along a communications channel in a given period of time.


1. (Electronics) the range of frequencies within a given waveband used for a particular transmission
2. (Electronics) the range of frequencies over which a receiver or amplifier should not differ by more than a specified amount
3. (Telecommunications) the range of frequencies used in a specific telecommunications signal


(ˈbændˌwɪdθ, -ˌwɪtθ)

1. the smallest range of electronic frequencies constituting a band, within which a particular signal can be transmitted without distortion.
2. the transmission capacity of an electronic communications device.


The difference between the limiting frequencies of a continuous frequency band expressed in hertz (cycles per second). The term bandwidth is also loosely used to refer to the rate at which data can be transmitted over a given communications circuit. In the latter usage, bandwidth is usually expressed in either kilobits per second or megabits per second.

Nevertheless, DTT is a very demanding market in terms of investment, companies have to secure a good channel position on the digital terrestrial LCN* system, the cost for which depends on how good the channel position is, and pay between two million and four million euros per year to frequency providers such as Mediaset, RAI, Persidera (controlled by Telecom Italia) and Prima TV (owned by Tarak Ben Ammar) just to lease the necessary digital bandwidth.
What these researchers propose is a way to achieve higher digital bandwidth, an incredibly efficient use of spectrum and a huge reduction in power consumption.
