Pre-deployment site surveys help in identifying potential sources of interference and determining the optimal locations for AP placement to ensure robust coverage and performance.

A high SNR indicates that the signal strength is much stronger than the background noise, which is essential for reliable wireless communication.

Using non-overlapping channels and staggering AP placements vertically helps to reduce co-channel interference between floors.

Passive site surveys involve listening to existing signals in the environment to understand the RF landscape without generating additional traffic.

Adding more APs and using directional antennas can help to cover dead zones and improve overall signal quality in areas with obstructions like cubicles.

CAPWAP (Control and Provisioning of Wireless Access Points) is used for secure communication between APs and wireless controllers.

PoE allows both power and data to be delivered through a single Ethernet cable, simplifying installation and reducing the need for additional power sources.

Proper VLAN and subnet configuration is essential for integrating new wireless controllers to ensure that traffic is correctly segmented and routed.

PoE is necessary to power lightweight APs directly from the switch, simplifying installation and reducing the need for external power adapters.

Configuring VLANs helps in segmenting traffic, reducing broadcast domains, and enhancing the network’s performance and security.

An anchor controller is used to manage guest traffic, providing isolation and security for guest users on the network.

802.11r fast roaming reduces the time required for clients to transition between APs, minimizing disconnections during movement.

Mobility groups help in managing client handoffs between APs, allowing for seamless roaming and continuous connectivity.

Fast roaming (802.11r) ensures that clients can transition between APs quickly and seamlessly, maintaining connectivity.

Mobility groups and fast roaming ensure that employees can move across the campus without experiencing disconnections, providing a seamless user experience.

N+1 redundancy provides an additional controller that can take over in case the primary controller fails, ensuring high availability.

SSO ensures that in case of a controller failure, a secondary controller can take over with minimal downtime, maintaining network reliability.

Load balancing helps distribute client connections evenly across APs, preventing any single AP from becoming overloaded and improving overall performance.

FlexConnect allows APs to continue operating and servicing clients even if the primary controller is unreachable, providing higher availability.

Redundant controllers with SSO ensure that if one controller fails, the other can seamlessly take over, minimizing disruption to the network.

802.11ac Wave 2 offers higher data rates and supports MU-MIMO, which increases network capacity and performance.

MU-MIMO allows multiple devices to communicate with an AP simultaneously, significantly improving performance in high-density environments.

RRM optimizes the RF environment by dynamically adjusting channel assignments and power levels to reduce interference and improve performance.

Directional antennas focus the RF signal in a specific direction, which can help reduce interference and increase the signal strength in targeted areas.

Manually adjusting the channels to ensure minimal overlap helps reduce co-channel interference, improving overall connectivity and performance.

WPA3 offers enhanced security features, including stronger encryption and protection against brute-force attacks, providing a more secure wireless network.

A staggered or honeycomb layout ensures even coverage and minimal interference, providing optimal performance in a large open-plan office.

Load balancing distributes client connections evenly across multiple APs, preventing any single AP from becoming overloaded and ensuring better overall performance.

Staggering the AP placement vertically helps ensure even coverage and minimizes interference between floors in a multi-story building.

Sector antennas are ideal for outdoor environments with high user density, as they provide focused coverage over specific areas, reducing interference and enhancing performance.
