 Large cases of liquid materials can cause higher signal loss compared to dry goods due to the way radio frequency (RF) waves interact with liquid, which can absorb and reflect the signals more than dry materials.

 Enabling AP fallback globally on the WLC allows access points to reconnect to their primary controller after they have connected to a secondary controller due to the primary being offline. This ensures that once the primary WLC is back online, APs will revert to it, maintaining the intended primary/secondary controller hierarchy.

 In an office environment with cubicles, signal propagation is most commonly affected by absorption. This is because the materials used in cubicle walls, such as fabric and other dense substances, tend to absorb the radio frequency (RF) signals used in WLANs, leading to attenuation.

 Devices that can tolerate at most 100 ms of delay when roaming are typically voice devices. Voice applications are sensitive to delays, and ensuring a maximum of 100 ms delay is a common design criterion for a wireless network supporting voice services. References: Designing Cisco Enterprise Wireless Networks (ENWLSD 300-425)

 The Cisco Aironet 3800 Series APs support mGig, which allows for higher throughput over existing cabling. However, the maximum cable length that supports 5G operation is limited by the quality of the cable and signal attenuation. Category 5e cabling can support 5G operation up to a length of 130 meters, which is within the acceptable range for maintaining the required signal integrity for 5G speeds.

 For an active survey where the application requires a minimum RF of -73 dBm, the mobile device used for the survey should have a receiver sensitivity of -70 dBm or better. This ensures that the device is sensitive enough to detect the minimum required signal strength for the application to function properly.

To address aesthetic concerns, using enclosures can effectively conceal wireless infrastructure, such as access points, within the environment. This helps maintain the visual appeal of the area while still providing the necessary wireless coverage.
