A wireless access point (AP) connects a group of wireless stations to an adjacent wired
local area network (LAN). An access point is similar to an ethernet hub, but instead of
relaying LAN data only to other LAN stations, an access point can relay wireless data to
all other compatible wireless devices as well as to a single (usually) connected LAN
device, in most cases an ethernet hub or switch, allowing wireless devices to
communicate with any other device on the LAN.
