Comprehensive and Detailed Explanation:
IEEE 29148-2018 outlines characteristics for both individual requirements and sets of requirements. While individual requirements should be necessary, feasible, and verifiable, the characteristic of being comprehensible applies to the entire set of requirements. This means that the collective requirements should be understandable to stakeholders, ensuring that the system's intended functions and constraints are clear and unambiguous.

Comprehensive and Detailed Explanation:
An elevation chart provides a vertical radiation pattern of an antenna, which is essential for understanding how the antenna directs energy above and below the horizon. In bridge link deployments, especially over varying terrains or between buildings of different heights, the elevation pattern helps in aligning antennas to ensure optimal signal propagation and reception. Requesting elevation charts from antenna vendors allows for informed decisions on antenna placement and orientation, leading to more reliable and efficient wireless links.

Comprehensive and Detailed Explanation:
Co-Channel Interference (CCI) in the 2.4 GHz band can significantly degrade WLAN performance due to the limited number of non-overlapping channels available.If the WLAN was primarily designed for 5 GHz, the
2.4 GHz band serves as a secondary or best-effort option.In such cases, turning off 2.4 GHz radios on some APs can reduce CCI by minimizing overlapping coverage areas, thereby improving overall network performance.

In Voice over WLAN (VoWLAN) deployments, it's crucial to differentiate between various types of voice- related traffic to ensure optimal Quality of Service (QoS).Real-Time Protocol (RTP) carries the actual voice payload, while control protocols like RTCP manage session control and quality feedback.Assigning distinct priority levels to these traffic types allows the network to prioritize voice payloads appropriately while still handling control traffic efficiently.

Conducting a site survey in environments such as heavy machinery repair facilities involves potential hazards, including moving equipment, loud noises, and other safety risks.Therefore, wearing Personal Protective Equipment (PPE) is essential to ensure the safety of the surveyor.
The CWDP-305 Official Study and Reference Guide advises:
"When performing site surveys in industrial or hazardous environments, always adhere to safety protocols, including the use of appropriate Personal Protective Equipment (PPE) such as hard hats, safety glasses, and steel-toed boots." This ensures that the survey is conducted safely and complies with occupational health and safety regulations.
