This document includes site survey specific information, Access Point configuration and installation data sheets, and RF coverage pattern maps. A wireless survey was performed at the customer site.  The purpose of the survey is to determine the number and placement of wireless access points necessary to provide ubiquitous coverage for the entire building. 1.1 Survey Overview 1.1.1 Floor Plan Overview The image below details the area that was surveyed. It includes the floor plan and the dimensions of the building. It can be useful to refer back to this view from some of the other graphs to help orient yourself. Dimensions X 66.30 m Y 82.55 m                                                        2 Introduction 2.1 Objective 2.1.1 Pre-Install/Post-Install Survey-Checkup The stated objective of this survey is to perform a spot-check of the existing deployment in order to establish that the current wireless infrastructure meets the needs of the users present.  The requirements against which these results will be compared are stated in the WLAN Deployment Requirements section detailed later in this report. 3 Methodology Multiple surveys were performed to allow finer detail and comprehensive data gathering. The process used to determine the existing RF data coverage in the facility is outlined below:  • Passive surveys were conducted throughout the facility to gather RF data (signal strength, noise level, signal-to-noise ratio, SSID and MAC addresses)  • Active Surveys were conducted throughout the facility. This was done to test performance and the roaming and connectivity ability of the Wi-Fi Network. 4 WLAN Deployment Requirements This section documents the user's stated requirements for satisfactory wireless service in the region being surveyed.  Note that these values can differ from site to site. 4.1 Deployment Requirements Description Threshold Desired Signal Coverage Minimum AP signal strength required -67 dBm Multiple AP Signal Coverage Number of APs required to provide coverage 2 Minimum AP signal strength required to provide coverage -67 dBm Channel Interference Interfered APs: Exclude APs if signal strength is weaker than -75 dBm Interfering APs: Exclude APs if signal strength is weaker than -85 dBm Measured PHY Data Rate Uplink Coverage Minimum AP PHY Data Rate required 5.50 Mbps Measured PHY Data Rate Downlink Coverage Minimum AP PHY Data Rate required 54.00 Mbps Predictive PHY Data Rate Downlink Coverage Minimum AP PHY Data Rate required 54.00 Mbps Signal Noise Ratio Coverage Minimum Signal Noise Ratio required 25 dBm Noise Level Maximum Noise Level Allowed -90 dBm User Capacity Maximum Users Supported per AP 15 With Load Balancing True Operating Mode Greenfield Operating Mode Allowed HT Mixed Operating Mode Not Allowed VHT Mixed Operating Mode Allowed Legacy Operating Mode Not Allowed Channel Width 40 MHz Channel Width Allowed 20HT MHz Channel Width Not Allowed 20 MHz Legacy Channel Width Not Allowed 80 MHz Channel Width Allowed 160 MHz Channel Width Allowed 802.11n Highest MCS Index Minimum Tx MCS index required 15 802.11ac Highest MCS Index Minimum Tx MCS index required 9 5 Current AP Placement and Configuration The floor plan below shows the locations of the currently installed APs or desired if this is a new deployment.

1.1.2 Survey Path This image displays the path taken during the survey process. The red dots indicate points that were 	clicked during the survey, whereas the blue ones represent sampling points taken by the application 	automatically.  6 Current Deployment Site Survey 6.1 Access Point Coverage Regions The image below shows the areas covered by the access points (in dBm). The color shown represents the AP with the strongest signal in any given area.This map will give you a visual representation of the 	Wi-Fi coverage area for the AP's.  6.2 Overall Signal Coverage  The image below displays the signal coverage (in dBm) at each point in the map layout. As a general 	rule, regions with signal levels below -67 dBm provide insufficient coverage for standard use (this value 	may vary depending on user requirements, service level agreements, applications used, number of 	users serviced, etc.). APs are displayed in their detected locations (and reflect the existing power and antenna properties). Note:  An active Wi-Fi area can incorporate a variety of environmental factors that can vary throughout the day and may adversely affect RF coverage. Note: Only the AP's that were placed on the floor plan prior to running the report will be shown on the floor plan image. Individual Signal Distribution 6.3 Channel Interference The image below displays the interference level (in percentage) at each point on the map layout. APs are displayed in their detected locations and reflect the existing power and antenna properties.   Note that the interference levels present in the environment can vary depending on several factors, such as the number of APs on a single channel, number of devices present, non-802.11 interferers, etc. Note: Only the AP's that were placed on the floor plan prior to running the report will be shown on the floor plan image.  Individual Channel Interference Distribution 6.4 Predictive PHY Data Rate (Downlink) The image below displays the predictive PHY data rate connection downlink at each point in the map layout. Connection Rates provides a direct insight into how well the network will support a real-world end-user client. When doing a Passive survey the ability to see the actual Data rate is not available. In order to provide Data Rates while doing a Passive survey we use Signal Strength to Data Rate mapping table. We take the detected signal strength and map it to a known Data Rate. A low Data Rate connection directly translates to lower throughput and performance for an end-user. Consistently low connection Rates are indicative of insufficient signal coverage, interference, noise, or miss-configured wireless devices. 6.5 Operating Mode  The image below displays the coverage of the 802.11 operating modes.  Refer to the legend for the color that corresponds to each mode (Legacy, Mixed HT, Greenfield HT, or Mixed VHT). The heat map displays the color of the operating mode that corresponds to the AP with the strongest signal detected at any given point. For example, locations shown as Mixed HT may contain Mixed VHT signal coverage and vice versa, but the AP with the strongest signal in that area utilizes a Mixed HT implementation. 6.6 Channel Width The image below displays the breakdown of the detected channel width. The color shown represents the Channel Width of the AP with the strongest signal in any given area. 6.7 802.11n Max MCS (AP Tx) The image below displays the AP's detected 802.11n MCS Transmission Rates. This heatmap reflects the 802.11n AP MCS Transmit mode that was detected. 6.8 802.11n Max MCS (AP Rx) The image below displays the AP's detected 802.11n MCS Receive Rates.  6.9 802.11ac Max MCS (AP Tx) The image below displays the AP's detected 802.11ac MCS Transmission Rates. This heatmap reflects the 802.11ac AP MCS Transmit mode that was detected. 6.10 802.11ac Max MCS (AP Rx) The image below displays the AP's detected 802.11ac MCS Receive Rates. 7 AirWISE Validation Against Requirements   This report section provides a comprehensive summary of all AirWISE data relating to the current survey 	project. Mboneni Wi-Fi's AirWISE engine allows users to specify minimum acceptable thresholds for various 	requirements within the network.  It compares the data gathered during the survey process against the 	requirements. Requirements that are not met are highlighted in their respective sections. Several sections 	also contain signal heat maps that help demonstrate exactly where the threshold violations can be found. 	Each section provides a breakdown of each requirement and displays a pass/fail rating based on how well 	the collected results stand up against the objectives.  8 Per SSID Report  	8.1 Access Points Information 	AP Name	Media Type	MAC Address	Channel	SSID	Power,mW	Max Signal	Number of AP: 		Total APs: 	   8.2 Signal Distribution 	Results for this section were not part of the survey  8.3 Noise Distribution 	Results for this section were not part of the survey   8.4 Signal/Noise Distribution 	Results for this section were not part of the survey  9 Conclusions  Overall, based on planned placement of the access points, more than       % of the facility will meet the levels of RF signal strength (-     dBm) and       dB SNR as specified in the Statement of Work. Adjusting the scale to -     dBm showed        % of the entire survey area was covered at this signal strength. In testing these areas it was noted that microwaves ovens and Bluetooth devices were in use. The RF noise floor in this facility is remarkably low, showing less than -         dBm.
