2、beacon period

The "beacon period" refers to a specific time interval in wireless communication, especially in the context of beacon frames in wireless networks. A beacon frame is a special type of frame transmitted by an access point (AP) or a base station to announce the existence of the network and provide essential information to devices within range.

During the beacon period, the AP periodically sends out beacon frames, typically at a fixed interval, to let nearby devices know about the network's presence. These frames contain essential network information such as the network's name (SSID), supported data rates, security settings, and other parameters.

Devices within range of the beacon frames use the information provided in them to make decisions about connecting to the network, roaming between different access points, or obtaining synchronization timing.

The length of the beacon period can vary depending on the network configuration, but it is usually in the order of milliseconds to seconds. Shorter beacon periods allow for more frequent announcements and quicker network detection, but can also consume more network resources.
