WLAN Operation Overview

In WLAN operation, the ______ mode is used to connect clients in a peer-to-peer manner without an AP.

Infrastructure mode is used to connect clients to the network using an ______.

Tethering is a variation of the ad hoc topology where a smart phone or tablet creates a personal ______.

A Basic Service Set (BSS) uses a single AP to interconnect all associated ______.

Clients in different BSSs cannot ______.

An Extended Service Set (ESS) is a union of two or more BSSs interconnected by a wired ______.

Clients in each BSS can communicate through the ______.

Carrier Sense Multiple Access Collision Avoidance, abbreviated as ______, is a protocol used in wireless communications.

To achieve successful association, a wireless client and an AP must agree on specific parameters such as SSID, password, network mode, and security ______.

Wireless clients connect to the AP using a passive or active scanning (probing) ______.

In passive mode, the AP openly advertises its service by periodically sending broadcast beacon frames containing the ______, supported standards, and security settings.

Active mode requires wireless clients to know the name of the ______.

The wireless client initiates the active scanning process by broadcasting a probe ______ frame on multiple channels.

Passive mode allows the AP to provide essential information such as the ______ settings to clients.

One key difference between passive and active mode is that passive mode does not require clients to actively ______ for the AP.

In passive mode, the AP sends out beacon frames containing the SSID, supported ______, and security settings.

Wireless clients must receive the ______ settings from the AP in order to successfully connect.

Successful association between wireless clients and APs depends on various parameters including channel ______ and band frequency.

The CAPWAP split MAC concept distributes functions between two components: the AP and the ______.

AP MAC functions include beacons and ______ responses.

The WLC performs all CAPWAP functions in ______ mode.

Channel saturation can be mitigated using techniques that use the channels more ______.

Direct-Sequence Spread Spectrum (DSSS) is used by ______ devices to avoid interference.

Frequency-Hopping Spread Spectrum (FHSS) requires sender and receiver to be ______ to know which channel to jump to.

Orthogonal Frequency-Division Multiplexing (OFDM) allows a single channel to use multiple ______.

A specific wireless channel may become ______ if the demand for it is too high.

In FlexConnect, client data traffic can be switched locally in ______ mode.

The original 802.11 standard uses ______ to transmit radio signals by rapidly switching frequencies.

The process of spreading a signal over a larger frequency band is known as ______.
