When performing a site survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with five floors, what aspect should you, as the site surveyor, keep in mind?
The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration.
The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible.
The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.
The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.
You were previously onsite at XYZ’s facility to conduct a pre-deployment RF site survey. The WLAN has been deployed according to your recommendations and you are onsite again to perform a post-deployment validation survey. When performing this type of post-deployment RF site survey for VoWiFi, what are two steps that must be performed? (Choose 2)
Coverage analysis to verify appropriate coverage and roaming boundaries
Spectrum analysis to locate and identify RF interference sources
Frequency-band hopping analysis to detect improper RF channel implementations
Protocol analysis to discover channel use on neighboring APs
Application analysis with an active phone call on a VoWiFi handset
A company has hired you to perform a pre-deployment site survey of their facility. During an interview, the network manager informs you that the new wireless network must use 5 GHz bands and OFDM, and VoWiFi handsets will be used extensively over the wireless network. What items do you need to include in the RF site survey report? (Choose 2)
A heat map demonstrating signal quality in areas where VoWiFi is supported.
Codec types and sampling rates for each VoWiFi phone
Security parameters and configuration steps for VoWiFi handsets.
Test results from an active survey with a VoWiFi handset
Results of OFDM versus ERP performance in each BSA
You are onsite with a client to perform a post-deployment site survey. When verifying a multiple channel VoWiFi deployment using a VoWiFi handset, which aspect is most important?
Performing protocol analysis with a single wireless adapter that is scanning all channels in use
Testing a constant conversation or handset tone while roaming from area to area, or performing an active survey
Configuring DSCP-to-802.11e QoS maps on the handset for each access category.
Verifying the VHT functionality to handle the call volume incurred by a single VoIP phone call.
You are being interviewed by ABC Company for employment as a wireless site survey expert. The interviewing manager asks you what items should be included in a site survey report generated as part of a manual site survey process. What answer would be accurate? (Choose 2)
Itemized list of equipment, licenses, and support contracts required for the facility
RF heat map illustrating coverage and signal quality for each frequency band
Documentation proving proper entry of wall material types into the site survey software
Documentation noting where each access point will be placed and how it will be mounted
Documentation noting how each WLAN user group will authenticate to the network
In addition to coverage analysis results, what should be included in a site survey report to ensure WLAN users experience acceptable performance?
Application Layer protocol availability analysis results
Layer 4 protocol availability analysis results
Capacity analysis results
WAN interface analysis results
What advantages does using predictive site survey modeling software offer over performing a manual site survey? (Choose 2)
Predictive modeling software can predict the ideal access point location 100% of the time, whereas the results from manual surveying are less reliable.
Predictive modeling software makes it simple to assess multiple different AP locations and then adjust and display the AP’s expected coverage pattern in almost real-time.
Predictive modeling software provides more reliable data than manual surveys when fine-tuning and validating access point placement after the installation.
The exact impact of interference sources from external networks can be more accurately measured when using predictive modeling software than with manual surveys.
It takes less time to create an initial site survey for a large facility when using
predictive modeling software than when performing a manual survey.
Your consulting firm has recently been hired to complete a site survey for a company. Your engineers use predictive modeling software for surveying, but the company insists on a pre- deployment site visit. What tasks should be performed as part of the pre-deployment visit to prepare for a predictive survey? (Choose 2)
With a spectrum analyzer, identify the type, amplitude, and location of RF interference sources, if any are present.
Evaluate the building materials at ABC’s facility and confirm that the floor plan documents are consistent with the actual building.
Test several antenna types connected to the intended APs for use in the eventual deployment.
Collect information about the company’s security requirements and the current configuration of their RADIUS and user database servers.
Install at least one AP on each side of the exterior walls to test for co-channel interference through these walls.
What item is essential for performing a manual RF site survey for a warehouse facility?
A facility map with an explanation of applications used in each area
I-Beam mounting kits for hanging temporary access points
Low-gain omni antennas for APs mounted high on warehouse ceilings
Predictive site survey software that supports highly directional antennas
NEMA enclosures that protect APs used for the survey
