The control data contains a beacon, broadcast, information exchange, upload information, and schedule assignment.
Once again, it is worth to mention that the beacon broadcast should be properly scheduled using a scheduling scheme such as the one proposed by the IEEE802.15.4 Task Group [14].
The beacon broadcast of power-saving access point in [54] carries a network allocation map (NAM) to indicate its temporal operations, which coordinates traffic delivery and power saving at both end stations and the access point (AP).

The beacon broadcast on a frequency very close to that of the American ships and many of the Japanese aircraft confused the ships in the darkness.
The graph in Figure 7 shows the NDTr for different size of beacon broadcasted to the vehicle moving at a constant speed (10 m/s) with different λ. Figure 8 shows the same but with a different speed (30 m/s).
These take advantage of WiFi standard beacons that broadcast both the SSID and MAC address of the access point constantly.
To television viewers, Mr. Rudd was familiar as Brian Mallory, the scheming Irish-born chauffeur, in the short-lived series "Beacon Hill," broadcast on CBS in 1975.
Facebook is still recovering from a fiasco last year when it launched a service called Beacon that broadcast its users' purchases on independent websites to their Facebook friends.
In the first phase, beacon nodes broadcast their position so they can be used as reference nodes.
