Karten in diesem Stapel (25)
- 1Provides RF coverage over a vast geographical area A WAN might traverse an entire state, region, or country or even span worldwideWWAN
- 2Cellular providers such as Sprint, Verizon, and Vodafone use a variety of competing technologies to carry data Examples of these cellular technologies are:GPRS
CDMA
TDMA
LTE - 3provides RF coverage to a metropolitan area such as a city and the surrounding suburbs One wireless technology that is often associated with a WMAN is defined by the 802.16 standard This standard defines broadband wireless access and is sometimes referred to as Worldwide Interoperability for Microwave Access (WiMAX)WMAN
- 4Wireless computer network used for communication between computer devices within close proximity of a user. The most common technologies of this type are Bluetooth and infraredWPAN
- 5Local Area Networks provide networking for a building or campus environment The 802.11 wireless medium is a perfect fit for local area networking simply because of the range and speeds that are defined by the 802.11-2012 standard and future amendmentsWLAN
- 6The main component of an 802.11 wireless network is the radio, which is referred to by the 802.11 standard as:Station (STA)
- 7802.11 topologies are known as:Service Sets
- 8Indicate the 4 types of service sets there are:BSS
ESS
IBSS
MBSS - 9They have the ability to address and direct wireless traffic at layer 2APs
- 10The upper-layer information that is contained in the body of an 802.11 wireless data frame is called:MSDU)
- 11it is used to interconnect a set of basic service sets (BSSs) via integrated LANs to create an extended service set (ESS)distribution system (DS)
- 12A logical physical medium used to connect access pointsDistribution system medium
(DSM) - 13provide the switch-like intelligence behind the scenesdistribution system services (DSS)
- 14A logical name used to identify an 802.11 wireless networkSSID
- 15is the cornerstone topology of an 802.11 network. The communicating devices that make up a BSS consist of one AP radio with one or more client stationsBSS
- 16Is two or more basic service sets connected by a Distribution System Medium Usually is a collection of multiple access points and their associated client stations, all united by a single DSMESS
- 17Allows proper communication between APs to forward traffic in a optimum wayMesh BSS (MBSS)
- 18defined as the Default Path Selection Protocol for an MBSS It is both proactive and reactive and is effectively a dynamic layer 2 routing protocolHWMP
- 19Converted into a wireless bridge Adds extra MAC-layer intelligence to the device and gives the AP the capability to learn and maintain tables about MAC addresses from the wired side of the networkBridge Mode
- 20Transformed into a workgroup bridge, providing wireless backhaul for connected 802.3 wired clientsWorkgroup Bridge Mode
- 21Performs as a repeater AP which extends the coverage area of a portal AP on the same channelRepeater Mode
- 22 Operates as a wireless backhaul radio for a mesh environment The backhaul radio may also allow for client accessMesh Mode
- 23Converted into a sensor radio, allowing integration into a Wireless Intrusion Detection System (WIDS) architecture In a continuous listening state while hopping between multiple channels Often referred to as monitor modeScanner Mode
- 24Is the default mode for an 802.11 client radio. When running in this mode, the client station will allow communication via an access pointInfrastructure mode
- 25Also known as Peer-to-Peer mode 802.11 client stations set to this mode participate in an IBSS topology and do not communicate via an access point All station transmissions and frame exchanges are peer-to-peerAd Hoc mode
