Comprehensive and Detailed Explanation:
Video-on-demand (VoD) applications are characterized by their need for high bandwidth to stream high- quality video content. However, unlike real-time applications, VoD can tolerate moderate latency and jitter because buffering mechanisms can compensate for these variances. While VoD requires a stable connection with minimal packet loss to maintain video quality, it is less sensitive to delays compared to voice or live video conferencing applications.

The primary objective of the initial pre-deployment meeting is to communicate the design decisions to the deployment team, ensuring they understand the design documentation.This alignment is crucial for the successful implementation of the WLAN infrastructure as per the design specifications.
The CWDP-305 Official Study and Reference Guide highlights the importance of clear communication during the deployment phase.

Manual identification of radar pulses using spectrum analysis charts can be challenging because radar signals often have low amplitude at the Wi-Fi receiver, making them difficult to detect visually.This limitation can lead to inaccurate assessments of DFS channel availability.Automated detection methods or using the actual WLAN equipment intended for deployment may provide more reliable results.

Comprehensive and Detailed Explanation:
In long-distance 802.11 bridge links, the default acknowledgment (ACK) timeout settings are typically configured for short-range communications. However, over extended distances, the propagation delay increases, and if the ACK timeout is not adjusted accordingly, the sender may retransmit frames unnecessarily, thinking the ACK was lost. By increasing the ACK timeout threshold to accommodate the longer propagation delay, you can reduce unnecessary retransmissions, thereby improving data flow and overall link performance.

Comprehensive and Detailed Explanation:
When conducting a predictive or passive RF site survey using survey software, accurately scaling the map is a critical initial step. Without proper scaling, distance and RF propagation calculations will be inaccurate, leading to flawed design outcomes.
"Scaling the map is a required step before placing APs, drawing walls, or runningsimul-ations in predictive tools. All distance-based calculations rely on this reference."
