Abstract

A wireless station, in a wireless LAN, includes a network interface to a network interface device, e.g., a NIC, that includes a transceiver, an antenna, at least a first power supply or energy holder. The wireless station supports transmission of data in frames of variable length. Frame fragmentation is implemented by dividing a (long) frame into a number of frame fragments. Each fragment is sent as a non-fragmented frame. The length of a time period before or between transmission of (consecutive) frame fragments is controlled in order to decrease energy consumption during a predetermined time interval.
