Comptia Tech + Certification 2.9 Definitions: Basic Capabilities of a Small Wireless Network

Which best describes the 802.11n wireless standard?

A Wi-Fi standard that introduced MIMO technology and supports both 2.4 GHz and 5 GHz bands with speeds up to 600 Mbps.

What is a key characteristic of the 802.11ac wireless standard?

Operates primarily in the 5 GHz band, supporting wider channels and multi-user MIMO for gigabit-level speeds.

Which statement accurately describes 802.11ax (Wi-Fi 6)?

A wireless standard that improves efficiency with OFDMA, supports 2.4 GHz, 5 GHz, and 6 GHz bands, and offers higher capacity in dense environments.

When planning a small wireless network, what do speed considerations involve?

Evaluating the maximum throughput of the wireless standard and how environmental factors reduce actual performance.

In wireless networking, what are interface and attenuation factors?

Physical and environmental conditions, such as walls, distance, and interference, that weaken or block wireless signals.

What is a key difference between older and newer Wi-Fi standards?

Newer standards generally offer higher speeds, better efficiency, and support for more devices compared to older standards.

In small wireless networks, what are “band options”?

The frequency ranges (such as 2.4 GHz, 5 GHz, and 6 GHz) that a wireless device can use for communication.

What is an advantage of using the 2.4 GHz band in Wi-Fi networking?

It offers longer range and better penetration through walls, though with more susceptibility to interference.

Which is a common benefit of using the 5 GHz band?

It supports higher data rates and less interference compared to 2.4 GHz, but has a shorter range.

Why is the 6 GHz band significant in newer Wi-Fi deployments?

It offers more available channels with less congestion, enabling faster speeds and lower latency for supported devices.
