 In communication networks, throughput is essentially synonymous to digital bandwidth consumption.In wireless networks or cellular communication networks, the system spectral efficiency in bit/s/Hz/area unit, bit/s/Hz/site or bit/s/Hz/cell, is the maximum system throughput (aggregate throughput) divided by the analog bandwidth and some measure of the system coverage area.In integrated circuits, often a block in a data flow diagram has a single input and a single output, and operate on discrete packets of information.
