WLAN Quiz

IEEE Standards and IoT

• IEEE 802.15.4 is designed for Internet of Things (IoT) applications, offering long-range connectivity options.

WiFi Terminology

• 'WiFi' is commonly used as a synonym for wireless networking technologies based on IEEE 802.11 standards.

High Throughput Standards

• IEEE 802.11n introduced the concept of Very High Throughput (VHT), enhancing data transmission speeds significantly.

IEEE Standards Coverage

• IEEE 802.11 standards cover both the Physical and Data Link Layers, ensuring comprehensive wireless communication protocols.

WLAN Characteristics

• A key characteristic of a Wireless Local Area Network (WLAN) is its ability to connect multiple devices without physical cables, allowing for mobility and flexible network configurations.

WLAN Performance Challenges

• WLAN performance can be affected by interference, signal weakening, and bandwidth limitations, which hinder effective communication.

Wired LAN Characteristics

• Wired Local Area Networks (LANs) typically offer stable and high-speed connections, with less susceptibility to interference compared to wireless networks.

WLAN Advantages

• A key advantage of WLANs over wired LANs is their flexibility and ease of installation, providing seamless connectivity without the need for extensive cabling.

Multipath Propagation in WLANs

• In WLANs, multipath propagation occurs when signals take multiple paths to reach a receiver, potentially causing interference but also enhancing signal reach.

WLAN Success Indicators

• The proliferation of devices such as smartphones, laptops, and tablets demonstrates the success and widespread adoption of WLAN technology.

Attenuation Characteristics

• Attenuation in WLANs refers to the reduction of signal strength over distance, which can impede effective communication, especially in larger areas.

Channel Allocation Challenges

• WLAN performance challenges related to channel allocation include congestion and limited spectrum availability, which can lead to reduced network efficiency and speed.
