Wireless Array28 Installing the Wireless ArrayPlanning Your InstallationThis section provides guidelines and examples to help you plan your XirrusWireless Array deployment to achieve the best overall coverage and performance.We recommend you conduct a site survey to determine the best location andsettings for each Array you install.The following topics are discussed: “General Deployment Considerations” on page 28 “Coverage and Capacity Planning” on page 30 “About IEEE 802.11ac” on page 37 “Failover Planning” on page 47 “Power Planning” on page 49 “Security Planning” on page 50 “Port Requirements” on page 52 “Network Management Planning” on page 56 “WDS Planning” on page 57 “Common Deployment Options” on page 60General Deployment ConsiderationsThe Wireless Array’s unique multi-radio architecture generates 360 degrees ofsectored high-gain 802.11a/b/g/n/ac coverage that provides extended range.(Note that XR-500/600 Series radios are omni-directional rather than sectored.)The number, thickness and location of walls, ceilings or other objects that thewireless signals must pass through may affect the range. Typical ranges vary For a complete discussion of implementing Voice over Wi-Fi on the Array,see the Xirrus Voice over Wireless Application Note in the XirrusResource Center. For optimal placement of Arrays, we recommend that a site survey beperformed by a qualified Xirrus partner.
