Wireless Fundamentals: Beacon Frame
Beacon Beacon is a management frame in the 802.11 wireless networking. It is periodically transmitted by an Access Point (AP) and serves as the first information a client device receives when looking to connect to a wireless network. Beacons help client devices understand available networks, synchronize with the AP, and make initial connection decisions. Importance of Beacons in Wireless Communication From a client device's perspective, the beacon frame services many purposes which is not just limited to initial connection. It helps client devices in following ways: Identify the Wireless Network : It provides essential information about available networks, allowing the client to recognize which networks are within range. Time Synchronization: Beacons help synchronize the timing between the AP and client devices, which is crucial for efficient communication. Supports Roaming: Beacons allows roaming clients to discover new APs and assess when to transition from one AP to ano...
