What is the IEEE of Bluetooth? - ANSWER-802.15 WPAN
What is WiMAX and it IEEE? - ANSWER--Worldwide Interoperability for
Microwave Access
-IEEE 802.16 WWAN
In cellular broadband there are two types of cellular networks, what are they? -
ANSWER-Global System for Mobile (GSM) and Code Division Multiple Access
(CDMA).
GSM is internationally recognized, while CDMA is primarily used in the US.
Typically, it is used by rural homeowners and businesses where cable and DSL
are not available. It is usually more expensive and requires a clear line of sight. -
ANSWER-Satellite Broadband
What is the 802.11 WLAN? - ANSWER-WiFi/wireless devices are based on IEEE
802.11
set of protocols and wireless local area network (WLAN) Wi-Fi computer
communication in various frequencies
-Radio frequency is 2.4 GHz
,What is the 802.11a? - ANSWER-5 Ghz frequency band
IEEE standard for transmitting data over a wireless network.
What are the two allocated radio frequency in 802.11 wireless LANs? - ANSWER-
2.4GHz and 5GHz
Which 802.11 standards exclusively use the 5 GHz radio frequency? - ANSWER-
802.11a
802.11ac
Which of the wireless networks typically uses lower powered transmitters for
short ranges? - ANSWER-WPAN
In wireless, what does AP stand for? - ANSWER-Access Point
What does SSID stand for? - ANSWER-shared service set identifier (SSID)
The wireless router advertises its wireless services by sending
______________containing its shared service set identifier (SSID) - ANSWER-
Beacons
What does QoS stand for and what does it do? - ANSWER-Quality of Service
is a feature of routers and switches which prioritizes traffic so that more
important traffic can pass first.
,What does WAP stand for and what is it exactly? - ANSWER-Wireless Access
Point
more generally just an access point, is a networking hardware devices that
allows other Wi-Fi devices to connect to a wired network.
What does Wi-Fi stand for? - ANSWER-Wireless Fidelity
technically, this is not the case. Wi-Fi is simply a trademarked term meaning IEEE
802.11x.
What is an Autonomous AP? - ANSWER--Standalone devices like a home router.
Where the entire WLAN configuration resides on the device.
-Sometimes called thick APs
-do not require a controller to control the AP and it use WLSE for management
software
-use for a network that requires only a couple of access points.
What does WLC stand for? - ANSWER-Wireless LAN Controller
What does AS stand for? - ANSWER-Autonomous System
What are Controller-based APs? - ANSWER--These devices require no initial
configuration and are often called lightweight APs (LAPs).
-Also called thin APs
, -Centralized management, configuration, encryption, updates and policy settings
through a centralized controller
LAPs - ANSWER-Lightweight Access Points
LWAPP - ANSWER-Light Weight Access Point Protocol
What is another name for LAPs? - ANSWER-Controller-based APs
LAG - ANSWER-Link Aggregation Group
What is MIMO? - ANSWER-Multiple Input Multiple Output.
Uses multiple antennas to increase available bandwidth for IEEE 802.11n/ac/ax
wireless networks. Up to eight transmit and receive antennas can be used to
increase throughput.
Which of the following components are integrated in a wireless home router?
-Access Point
-Switch
-Router
-Range Extender - ANSWER-Access Point, Switch, Router
What is infrastructure mode in WLAN? - ANSWER-A wireless router or AP
connects wireless clients to a wired distribution system.
