When conducting a site survey for real-time traffic over wireless, which two design capabilities of smartphones and tablets must be considered? (Choose two.)
When conducting a site survey for real-time traffic over wireless, it is important to consider the design capabilities of smartphones and tablets. These devices typically have fewer antennas compared to laptops, which can affect their wireless performance and capacity. Additionally, smartphones and tablets usually achieve lower data rates than laptops, impacting their ability to handle high-throughput traffic efficiently. Understanding these limitations is crucial for designing a robust wireless network that can support real-time applications on such devices.
Which two criteria must be considered when conducting an outdoor bridge site survey? (Choose two.)
When conducting an outdoor bridge site survey, it is crucial to consider weather and the Fresnel zone. Weather can significantly impact signal strength and reliability by causing interference such as rain fade or wind sway. The Fresnel zone is an important concept in radio communications that refers to an elliptical area around the line-of-sight path where obstructions can cause signal degradation. Considering these two criteria ensures optimal performance and reliability of the wireless link.
An engineer is performing a predictive wireless design for a medical treatment environment, which requires data and voice services. What is the minimum requirement for the design?
In a medical treatment environment that requires data and voice services, it is crucial to have overlapping coverage with a robust signal to ensure reliability and minimize interference. Ensuring two access points provide coverage of at least -67 dBm is essential for maintaining consistent and high-quality voice and data services, as this level of signal strength is necessary for supporting such services in a demanding environment. Overlapping coverage provides redundancy, which is particularly important in environments where uninterrupted service is critical.
Which non-Wi-Fi interferer can be identified by Metageek Chanalyzer?
Metageek Chanalyzer is a spectrum analysis tool used to identify sources of interference in the Wi-Fi spectrum. Jammers, which emit continuous signals and are used disrupt wireless communications, can be identified by tools like Chanalyzer. The other options (PDAs, smartphones, and printers) are Wi-Fi devices that use Wi-Fi for their connectivity. Therefore, jammers are the correct answer as they are non-Wi-Fi interferers that can be identified by Metageek Chanalyzer.
A wireless engineer is utilizing the voice readiness tool in Cisco Prime for a customer that wants to deploy Cisco IP phones. Which dBm range is the network inspected against?
The appropriate dBm range for voice readiness in a wireless network is typically between -72 dBm and -67 dBm. Cisco Prime often uses -72 dBm as the lower end of the acceptable signal strength range for reliable voice communication. Therefore, the correct answer is the option that falls within this range.
