A protocol that helps avoid collisions before data transmission by checking the channel.

The step where a device listens to the channel to see if it is free before transmitting.

A wait time a device observes after detecting a busy channel before rechecking.

A method to reserve a channel momentarily before data transmission using Request-to-Send and Clear-to-Send signals.

The actual sending of data once the channel is clear and the backoff is over.

A signal sent back to the sender confirming that data was received successfully.

A unique name for a specific wireless network that users select to connect.

A unique identifier (MAC address) for a specific access point in a wireless network.

The fundamental unit of a Wi-Fi network consisting of one access point and its connected devices.

A frequency band providing more channels and capacity than 2.4 GHz.

The number of channels varies by region due to regulations.

Sub-bands within the 5 GHz band with specific regulatory rules.

Feature requiring Wi-Fi to switch channels if radar signals are detected.

Adjusts Wi-Fi device transmission power to the minimum required level.

Variations of channel widths impacting data throughput and performance.

Typically used in 802.11ac, combining four 20 MHz channels for high throughput.

An antenna focused in a single direction for long-range coverage.

An antenna designed for moderate directional coverage.

A directional antenna with a narrow beam, used for long-range communication.

An antenna with a highly concentrated beam for point-to-point communication.

A wireless network without encryption, allowing easy access and data interception.

A wireless network that scrambles data for secure transmission.

An early encryption protocol for wireless networks supporting 60 and 128-bit keys.

A communication setup between two specific points, often using unidirectional antennas.

Standards that determine the level of encryption and security for wireless networks.

A Virtual Private Network that encrypts your internet connection for security.

Devices that allow easy cable connections and management in networking.

Modular connectors used for terminating network cables in patch panels.

An impact tool used to secure wires into keystone jacks effectively.

A tool designed to remove the outer insulation from cables safely without damage.

A tool used to cut cable to the desired length before termination.

Devices that check the connectivity and mapping of network cables.

Two wiring standards for connecting wires in network cables correctly.

The process of measuring, cutting, and stripping cables before termination.

Separating pairs of wires after stripping to prepare for insertion into jacks.

The final step to ensure all wires are correctly connected and functioning.

A shared password for wireless network authentication, used by all users for access.

WPA2 using a pre-shared key for authentication, requiring a passphrase of 8 to 63 characters.

An improved wireless security protocol that uses Simultaneous Authentication of Equals for password protection.

A standard simplifying Wi-Fi connections without manual password entry, using a button or PIN.

Requires individual credentials for each user or device, rejecting a single shared password for access.
