Abstract

In the field of communications technologies, an operating method of a wireless Access Point (AP) device and the wireless AP device are provided according to the embodiments of the present invention, to decrease the power consumption and prolong the operating time when a battery is used for power supply. One method includes: in the absence of data connection, after transmitting N broadcast frame signals with full power, transmitting M broadcast frame signals with low power. Another method includes: in the presence of data connection, establishing a connection with a lowest one of all compatible transmission rates; judging whether a current transmission rate is greater than or equal to a sum of a current actual throughput and a preset system parameter; and if the current transmission rate is smaller than the sum of the current actual throughput and the preset system parameter, increasing the transmission rate.
