Illustratively, the long-distance transmission mode is a transmission mode which has a relatively long transmission distance and consumes relatively high power consumption when transmitting data, and the short-distance transmission mode is a transmission mode which has a relatively short transmission distance and consumes relatively low power consumption when transmitting data.
