Comprehensive and Detailed Explanation:

For Voice over IP (VoIP) over WLAN, seamless roaming is critical to maintain call quality. To achieve this:

D.Ensuring that at least two access points (APs) are visible with adequate signal strength from any location allows client devices to roam between APs without dropping the connection. This overlap facilitates smooth handoffs and maintains call continuity.

A.While measuring cell overlap is useful, the key is to design the network to provide the necessary overlap, not just measure it.

B.Increasing output power can lead to larger cells but may cause interference and reduce the number of available channels, which is counterproductive in dense environments.

C.Higher gain antennas focus the signal, which may not provide the desired omnidirectional coverage needed for consistent overlap.

For long-range point-to-point bridge links, dish antennas are preferred due to their narrow beamwidth and high gain. An 11 dBi dish antenna focuses energy more efficiently in a single direction, which reduces the amount of Intentional Radiator (IR) power needed to meet link budget requirements.

From CWDP-305:

“Dish antennas provide high gain and a narrow beam, making them ideal for point-to-point bridge links over long distances. This minimizes interference and maximizes EIRP efficiency.”

Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.When integrating with an LDAP directory, RADIUS servers can authenticate users against the LDAP database before granting access to the WLAN infrastructure.

The CWDP-305 Official Study and Reference Guide notes:

"What service must be implemented on your customer's network to authenticate users against an LDAP database before granting access to the WLAN infrastructure? B. RADIUS"Pass4Success

A survey tray is a lightweight, portable platform that allows WLAN engineers to carry laptops and survey gear comfortably while walking and taking measurements. It helps maintain posture and prevents strain during long survey sessions.

From CWDP-305:

“Using a survey tray allows the engineer to maintain proper posture and prevent back strain while conducting extended walkabouts during site surveys.”
