CWDP Wi-Fi Design CWDP-305 Exam Dumps

When conducting a predictive site survey, it's essential to configure the simulated APs to reflect the expected real-world conditions.If dynamic Radio Resource Management (RRM) will be utilized, setting the AP transmit power to an estimated average level that matches the expected client devices, such as 25 mW, ensures that the predictive model accurately represents the operational environment.This approach helps in designing a WLAN that provides optimal coverage and performance.

In environments where both WMM-PS (Wi-Fi Multimedia Power Save) certified and non-WMM-PS client devices coexist, disparities in performance and battery life can occur. WMM-PS enhances power-saving mechanisms by allowing devices to enter low-power states and schedule transmissions efficiently. Non-WMM-PS devices, lacking this capability, rely on traditional power-saving methods like PS-Poll, which are less efficient. As a result, WMM-PS devices benefit from improved battery life and performance, while non-WMM-PS devices may experience reduced efficiency.

Comprehensive and Detailed Explanation:

In a Single Channel Architecture (SCA), all APs operate on the same channel and present a single virtual BSSID to clients. The WLAN controller manages client associations by directing the most appropriate AP to handle communication with the client, typically based on the strongest Received Signal Strength Indicator (RSSI).

This architecture simplifies client roaming and reduces co-channel interference, as the controller orchestrates AP transmissions to prevent collisions.

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.
