Beacon frame

Beacon frame

Beacon frames are part of the IEEE 802.11 wireless network protocol.

Beacon Frames are frames that have control information and are transmitted in each of the 11 channels and help a wireless station to identify nearby wireless access points (AP) in passive scanning mode. They tell the stations in the Basic Service Set (BSS) about the existence of the network. They can also be transmitted by the AP for polling purposes. The Beacon Frame sent by the AP contains control information and can be used by Mobile stations to locate an AP if it is on active scanning mode.

Beacon frame components

In the beacon frame body, we can find the timestamp, the beacon interval, capability information, SSID, Frequency-hopping (FH) Parameter Set, Direct-Sequence (DS) Parameter Set, Contention-Free (CF) Parameter Set, IBSS Parameter Set and also Traffic Indication Map (TIM).
