A specific probability distribution function intended to model calling patterns of users who fail to find available facilities.
Note: There are several blocking formulas. The applicability of each to a given situation depends on its underlying assumptions regarding caller behavior.

In telecommunications, a network that has fewer transmission paths than would be required if all users were to communicate simultaneously.
Note: Blocking networks are used because not all users require service simultaneously. Certain statistical distributions apply to the patterns of user demand.

In a spectrum of frequencies, a region in which the spectral density, i.e., power per hertz, is proportional to the frequency.

See chroma keying.

A low-power, short-range, rf technology that allows the connection of intelligent communications devices or appliances in a household or an office in a short-range wireless network. Examples of Bluetooth applications are transferring data between cell phones, radios, pagers, personal digital assistants, notebook computers, video and still cameras, audio players, and local area networks.
