In a network client (station), messages are sent to the current connected access point to keep the connection during periods of idle activity. These messages are called Keep-Alive. Keep-Alive messages are generated independently by the WLAN device (station) according to the host configuration, allowing the host to optimize the length of its low power-time interval. The Keep-Alive messages are not sent from the Host, thus, the mechanism improves the power consumption. Also, the frequency of messages have a direct effect on power consumption; therefore, the longer the interval between Keep-Alive messages, the more efficient in power consumption.
