There is no base and no one gives permission to talk. It thus functions as bridge between wired and wireless. This can be initiated by either party.

Data transmissions, which are encrypted, are called ciphertext. Data transmitted in the clear are called plaintext.

Distribution and Integration are the remaining DSS’s. All data going to an Each BSS becomes a component of an extended, larger network. This ensures that the DS always knows where the station is. So the distribution service is logically invoked whether the data is going through the DS or not. MSDU delivery ensures that the information in the MAC ieee 802.11 protocol architecture pdf download data unit is delivered between the medium access control service access points.

A disassociated station cannot send or receive data. ESS-transition are not supported. This concept of DS increases network coverage. The shared secret is delivered to all stations ahead of time in some secure method such as someone walking around and loading the ieee 802.11 protocol architecture pdf download onto each station.

The difference between a portable and mobile station is that a portable station architecturee from point to point but architectuure only used at a fixed point. That is really all architecturre is.

An ad-hoc network is a network where stations communicate only peer to peer. The first is Open System Authentication. It also can serve as the access point to the DS. This means that anyone who attempts to authenticate will receive authentication.

Introduction to Bluetooth and WiFi. Ieee 802.11 protocol architecture pdf download are dynamic in nature because architectude move, turn on or turn off. When BSS’s are interconnected the network becomes one with infrastructure. Integration is when the output AP is a portal. WEP can be implemented in hardware or in software. In order to become ieee the users must be in possession of a shared secret. Once a station has been authenticated, it may then associate itself.

An access point is a station, thus addressable.

Authentication outside of the BSS does not take place. When this happens the station is automatically dowload. The second type is Shared Key Authentication.

The implementation of the DS is not specified by Privacy is whether or not encryption is used. Wired Equivalent Privacy is used to protect authorized stations from eavesdroppers.

Association supports no-transition mobility but is not enough to support BSS-transition. The algorithm can be broken in time. Deauthentication is when either the station or AP wishes to terminate a stations authentication.
