For example, in wireless communications the channel is often modelled by a random attenuation (known as fading) of the transmitted signal, followed by additive noise. Different communication channels are more or less effective at transmitting different kinds of information. The twisted pair wire, coaxial cable, fiber optic cable, microwave, satellite etc. Besides being used for long-distance internet traffic, T3 lines are often used to build the core of a business network at its headquarters. Unlike the other communication networks, in an all-channel network there is no direct leader and all levels of employees can communicate with anyone else of any level.

External communication is often handled by marketing and sales. Examples of digital channel models are: In an analog channel model, the transmitted message is modelled as an analog signal. The strict hierarchical web of communication cannot function efficiently on its own and hence there exists a communication channel outside of this web. The model may reflect the following channel impairments: These are examples of commonly used channel capacity and performance measures: In networks, as opposed to point-to-point communication, the communication media is shared between multiple nodes (terminals). This kind of communication flow is increasingly the norm in organizations (in the same way that cross-functional teams are becoming more common), since it can maximize the efficiency of information exchange.

This is likely to make employees feel satisfied with their level of access to channels of upward communication and less apprehensive about communicating with their superiors. There are three different types of telecommunication and computer networking channels to be aware of: simplex, half-duplex, and full-duplex. The data are realized as electromagnetic signals (radiowave, microwave, electrical voltage, etc.). All-Channel Network. Smiling, she turns to Frances and says, “Mission accomplished.”. A channel has a certain capacity for transmitting information, often measured by its bandwidth in Hz or its data rate in bits per second.
