Embodiment Construction

[0012] This specification discloses an access point (AP) power saving mode, which can be used when there are no active wireless stations served by the AP.

[0013] definition

[0014] Station, wireless station, mobile station, wireless device, mobile device, and network card (NIC) are equivalent functions / devices capable of wireless communication with an access point.

[0015] An access point (AP) may be a wireless station used in a wireless local area network (WLAN) and may support IEEE802.11 or equivalent communication. The AP may also include a router and may be referred to as an AP / router. Other wireless stations can be associated with the AP. APs can provide access to networks and / or computers outside the range of those networks and / or computers that can be associated with the AP by routing traffic from the associated wireless station to other devices outside the range of the WLAN. Computer access.

[0016] A soft AP is a software application that enables a wireless client (su...

Abstract

A power-save mode for a wireless access point is provided. The wireless access point can determine if other wireless stations are associated with the wireless access point. If there are no associations, then the wireless access point may enter a power-save mode. Associations may be determined by recent associations with the wireless access point or by media access control address activity. In the power-save mode, power may be reduced to at least one area of the wireless access point. In the power-save mode, the wireless access point may stop sending beacon signals. If the wireless access point receives a trigger signal, the wireless access point may leave the power-save mode.

Description

Technical field [0001] This specification describes devices and methods generally related to saving power in a communication system, especially in a wireless LAN. Background technique [0002] Access point (AP) is an important wireless device in WLAN technology. Wireless devices can use wireless technology to transfer data via access points. Typically, APs operate such that they can always be on and active, even if there are no active wireless stations associated with them. Consider a scenario in a residential environment where a user connects a wireless station to an AP and uses the connection to browse. If the user then travels from the house to, for example, the office, the user may return to the house from his work place after 6-8 hours. A residential-based AP may still be on and operating actively, where AP beacons are transmitted every configured interval (a typical value is every 100ms). The AP has consumed considerable power and has not provided useful communication t...
