METHOD AND DEVICE FOR ACCESSING WIRELESS LOCAL AREA NETWORK

摘要

Embodiments of the present invention provide a method and a device for accessing a wireless local area network. The method comprises: dividing a beacon interval into at least three time periods, a first time period in the at least three time periods being used for a station having cached data at an access point (AP) to send a power save poll (PS-Poll) frame, a second time period in the at least three time periods being used for a sensor to perform a contention access, a third time period in the at least three time periods being used for the sensor station and a non sensor station to perform a contention access, and the station being formed by a sensor station and a non sensor station; and sending a beacon frame, the beacon frame carrying information of the at least three time periods. In this way, the power consumption increase caused by simultaneous contention of the sensor station and the non sensor station can be restrained, and the access success rate of the sensor station can be effectively improved.
