EAP-PEAP is the most suitable 802.1X-based authentication method for environments that do not have a public key infrastructure (PKI). It uses a server-side certificate but does not require client-side certificates, simplifying deployment while maintaining strong authentication.

From CWDP-305:

“EAP-PEAP allows secure authentication using usernames and passwords without requiring client certificates, making it ideal for organizations lacking PKI infrastructure.”

Other options:

EAP-TLS requires a PKI and client certificates (not suitable here).

PSK (pre-shared key) options don’t use 802.1X.

TKIP/RC4 is deprecated and insecure.

An active site survey involves connecting to the WLAN and measuring performance metrics such as throughput and signal strength. During this process, as the surveyor moves through the environment, the client device may transition between different access points. This movement inherently tests the network's roaming capabilities, assessing how seamlessly a client can switch from one AP to another without service interruption.

In scenarios where physical access to the ceiling is restricted, such as when ladders are not permitted, using a laser distance measurer is the most accurate and cost-effective method to determine ceiling height. Laser measurers provide precise distance readings by emitting a laser beam to the target surface and calculating the time it takes for the reflection to return. This tool eliminates the need for estimations or indirect calculations, ensuring accurate measurements essential for WLAN design.

Allowing employees to use their own devices on the company network—commonly known as BYOD (Bring Your Own Device)—can provide several operational benefits:

Enhanced Productivity:Users are more familiar and comfortable with their personal devices, leading to faster adoption and efficiency.

Decreased Costs:The organization can reduce capital expenditures on hardware purchases and lifecycle management.

Increased Satisfaction:Employees prefer working on familiar platforms, which contributes to higher morale and satisfaction.

From the CWDP-305 guide:

“BYOD deployments can enhance user satisfaction and productivity while reducing costs associated with device provisioning. However, they require proper security and access controls.”

160 MHz channels consume a large portion of the available spectrum. Due to DFS and regulatory limitations, very few 160 MHz-wide channels are available in the 5 GHz band. This makes them impractical for most enterprise environments where avoiding interference and ensuring channel reuse are critical.

From CWDP-305:

“Due to the limited number of non-overlapping 160 MHz channels in the 5 GHz band—and DFS limitations—these channels are difficult to deploy in enterprise WLANs. This limits their usefulness in dense environments.”

High gain omni-directional antennas are designed to radiate RF signals uniformly in all horizontal directions, resulting in a circular pattern on the azimuth chart. However, to achieve higher gain, these antennas compress the vertical radiation pattern, creating a flattened, donut-shaped pattern on the elevation chart. This design focuses the energy horizontally, extending the coverage area while minimizing vertical dispersion, which is ideal for environments requiring broad horizontal coverage.cwnp.com

Defining wall materials (e.g., drywall, brick, concrete) in WLAN design software is essential for accurate RF modeling. Different materials attenuate RF signals to varying degrees, and propagation models account for these losses to calculate realistic signal coverage.

From CWDP-305:

“Accurate modeling of RF signal behavior requires defining wall and obstacle materials to account for signal attenuation and reflections. This improves the accuracy of predictive design tools.”

CAPWAP (Control and Provisioning of Wireless Access Points):Modern standard protocol for tunneling management and data frames between APs and WLCs.

GRE (Generic Routing Encapsulation):Sometimes used by vendors as an alternative tunneling method, especially for data transport.

From CWDP-305:

“CAPWAP is the most widely used protocol for communication between access points and controllers. GRE is also utilized in some vendor implementations for tunneling user data.”

For cable runs exceeding 55 meters (180.5 feet) and to support 802.3bz MultiGig speeds (2.5GBASE-T and 5GBASE-T), it's recommended to use Cat-6a cabling. Cat-6a cables are designed to handle higher frequencies and provide better performance over longer distances compared to Cat-5e or Cat-6, making them suitable for MultiGig applications.

The CWDP-305 Official Study and Reference Guide highlights the importance of selecting appropriate cabling to support higher data rates:

"When deploying MultiGig Ethernet, especially for cable lengths exceeding 55 meters, Cat-6a cabling is recommended to ensure reliable performance and compliance with standards."

Comprehensive and Detailed Explanation:

When transitioning from a centralized to a distributed data forwarding model in a WLAN architecture, it's important to consider the capabilities of the existing APs. Some APs designed specifically for centralized forwarding may lack the necessary hardware or firmware support to operate effectively in a distributed forwarding mode. This can lead to compatibility issues and may require hardware upgrades or replacements to ensure proper functionality in the new architecture.
