-62-AP within a BSS so that the node can participate in data exchanges with other mobile nodes. 14.8 (1) In order to transmit over a wired LAN, a station must be physically connected to the LAN. On the other hand, with a wireless LAN, any station within radio range of the other devices on the LAN can transmit. In a sense, there is a form of authentication with a wired LAN, in that it requires some positive and presumably observable action to connect a station to a wired LAN. (2) Similarly, in order to receive a transmission from a station that is part of a wired LAN, the receiving station must also be attached to the wired LAN. On the other hand, with a wireless LAN, any station within radio range can receive. Thus, a wired LAN provides a degree of privacy, limiting reception of data to stations connected to the LAN. 14.9 Shared key authentication is more secure because it requires the use of a secret key shared only by the two sides. Open system authentication is simply a protocol for agreeing to communicate and provides no security features. A
