One frequency in a trunking system that is used to convey system information such as frequency assigned for a talkgroup call and what talkgroup a radio has selected.
Refers to the control data portion of an overall data packet that is transmitted from one RF device to another. For example with Squeak digital wireless audio the overall data packet typically consists of a digitized left audio channel, a digitized right audio channel, and control information.
With a cellular telephone system there are a few channels that allow the base stations to transmit information to the cell phones in its area.
A lighting control concept analogous to a control slider or fader. On manual or preset controllers this may refer to an actual fader or slider. On a computer memory console a channel may only be represented by a number which is assigned by the system to control any number of physical dimmers, color scrollers, or other devices. Generally a control channel represents the smallest easily divisible set of controls a designer has over groups of lighting instruments. A soft patch or pin patch is used to assign dimmers or groups of dimmers to individual control channels. See Also: Pin Patch Soft Patch Dimmer Color Scroller Computer Memory Console Preset Board
Within a cellular telephone system, several of the channels are assigned as 'control' channels. Instead of supporting voice data transmissions, cellular control channels allow the base station to broadcast information to the cellular devices in its area. Cellular devices continuously monitor this broadcast information, selecting the base station that provides the strongest signal.
A logic channel carrying network information rather than the actual voice or data messages transmitted over the network.
A channel used for transmission of digital control information from a base station to a cellular phone (forward control channel) or from a cellular phone to a base station (reverse control channel).
Control Channel is an allocated channel in OBS environment where the BHP is transmitted.
A Control Channel is a continuous, dedicated data stream broadcast by a trunked radio system controller for certain systems, such as Motorola and EDACS.
