• The optional Parameter Sets indicates features of the specific signalling
methods in use (such as frequency hopping spread spectrum, direct

Bridge
A connection between two local area networks (LANs) using the same protocol,
such as Ethernet or IEEE 802.1x.
Broadcast
A Broadcast sends the same message at the same time to everyone. In wireless
networks, broadcast usually refers to an interaction in which the access point sends
data traffic in the form of IEEE 802.1x Frames to all client stations on the network.
Some wireless security modes distinguish between how unicast, multicast, and
broadcast frames are encrypted or whether they are encrypted.
See also Unicast and Multicast.
Broadcast Address
See IP Address.
BSS
A basic service set (BSS) is an Infrastructure Mode Wireless Networking
Framework with a single access point. Also see extended service set (ESS) and
independent basic service set (IBSS).
