In the field of computers, the definition of transmission capacity is the ability of electronic transfer present in a wireless network that is not dedicated to other uses. It is a metric that indicates the data transmission ability of a wireless network.
Transmission capacity may be expressed as the maximum average number of concurrent successful transmissions per unit taking place on a network at any given time.
In the energy industry, transmission capacity refers to the ability of a power supply network to deliver power to various areas or the amount of electricity that may be transferred from a source to a destination. Engineers design systems of power lines, cables, circuit breakers, switches and transformers to handle this transmission as efficiently as possible. Transmitting at high voltages increases transmission capacity and results in less power being lost during transmission.
