public final class Dot11SsidElement extends Dot11InformationElement
IEEE802.11 SSID element1 1 0-32 +----------+----------+------------- |Element ID| Length | SSID +----------+----------+------------- Element ID: 0
A SSID field of length 0 is used within Probe Request management frames to indicate the wildcard SSID. The wildcard SSID is also used in Beacon and Probe Response frames transmitted by mesh STAs. When the UTF-8 SSID subfield of the Extended Capabilities element is equal to 1 in the frame that includes the SSID element, the SSID is interpreted using UTF-8 encoding.- Since:
