CCNA 1 Module 12 IPv6 Addressing

is a type of Local Area Network (LAN) that uses wireless communication to connect any type of network client or device

is the receiving end of the radio link, and it has the capability to reach back to the LAN

Wireless technology type within WLAN.

Low-power, short-range wireless network.

Large geographic area such as city or district.

Extensive geographic area for national or global communication.

IEEE standard for device pairing.

IEEE 802.16 standard for broadband internet.

Carry both voice and data. Used by phones, automobiles, tablets, and laptops.

Cellular technology that is internationally recognized.

Cellular technology primarily used in the US.

Internet via satellite dish for rural areas.

Ability to work with older versions or systems.

All wireless devices operate in the range of the electromagnetic spectrum. Ranges used by WLAN networks (2.4 and 5 GHz).

An organization setting specifies how a radio frequency is modulated to carry information

Typically interconnects wireless devices using a small, wireless router

Device enabling wireless communication in laptops, tablets, smartphones.

Can be categorized as either autonomous APs or controller-based APs

Devices enhancing wireless signal coverage.

Peer-to-peer client connection without AP.

Client connection via AP to network.

Smartphone creating personal hotspot.

Uses single AP to interconnect all associated wireless clients

A union of two or more BSSs interconnected by a wired distribution system

Resembles Ethernet frame but with additional fields

It is a 2-byte starting field composed of 11 subfields

Specifies time period and acknowledgment channel occupancy

Carrier sense multiple access with collision avoidance; determines how and when to send data

For wireless devices to communicate over a network, they must first associate with an AP or wireless router

AP openly advertises its service by periodically sending broadcast beacon frames

Wireless clients must know the name of the SSID.

Control and Provisioning of Wireless Access Points; protocol that enables an access controller (AC) to manage a collection of APs

Divides the implementation of the MAC functions between the AP and the controller.

Management frame that contains all the information about the network

Datagram Transport Layer Security; secures CAPWAP control channel between AP and WLC

Enables AP configuration and control of APs over a WAN link

The WLC is reachable; the FlexConnect AP has CAPWAP connectivity with the WLC through the CAPWAP tunnel

The WLC is unreachable; the FlexConnect AP has lost CAPWAP connectivity with the WLC.

If the demand for a specific wireless channel is too high, the channel may become oversaturated, degrading the quality of communication

Direct-Sequence Spread Spectrum; modulation technique spreading signal over larger frequency band

Frequency-Hopping Spread Spectrum; rapidly switches carrier signal among frequency channels

Orthogonal Frequency-Division Multiplexing; a single channel uses multiple sub-channels on adjacent frequencies

The 2.4 GHz band is subdivided into multiple channels

Important for planning AP locations in WLAN deployment.

Includes interception of data, wireless intruders, DoS attacks, rogue APs

An AP or wireless router connected to a corporate network without explicit authorization

Hacker intercepts data between two legitimate entities.

APs and some routers allow the SSID beacon frame to be disabled

Permits/denies wireless access based on physical MAC address.

No password required for free internet access in public areas.

Requires pre-shared password between both parties to connect.

Temporal Key Integrity Protocol; used by WPA and provides support for legacy WLAN equipment

Advanced Encryption Standard; used by WPA2 with CCMP for secure encryption

Includes SAE, 802.1X/EAP, OWE, and DPP for enhanced security
