Abstract
A WLAN (Wireless Local Area Network) communication device for performing communication in a WLAN network is provided that comprises a physical connection unit, a physical connection oscillator, and a control unit. The physical connection unit is for providing a physical connection of the WLAN communication device to a wireless communication medium. The physical connection oscillator is for providing a physical connection clock signal to the physical connection unit. The control unit is for controlling operation of the physical connection oscillator. The WLAN communication device is operable in a communication mode and in a deep sleep mode. The control unit is adapted to deactivate the physical connection oscillator when the deep sleep mode is entered. Embodiments may provide an extended reduction of the power consumption of the WLAN communication device.
