Wi-Fi Array60 Installing the Wi-Fi ArrayPlanning Your InstallationThis section provides guidelines and examples to help you plan your Xirrus Wi-FiArray deployment to achieve the best overall coverage and performance. Werecommend you conduct a site survey to determine the best location and settingsfor each Array you install.The following topics are discussed: “General Deployment Considerations” on page 60 “Coverage and Capacity Planning” on page 62 “IEEE 802.11n Deployment Considerations” on page 72 “Failover Planning” on page 80 “Power Planning” on page 82 “Security Planning” on page 83 “Port Requirements” on page 86 “Network Management Planning” on page 89 “WDS Planning” on page 90 “Common Deployment Options” on page 93General Deployment ConsiderationsThe Wi-Fi Array’s unique multi-radio architecture generates 360 degrees ofsectored high-gain 802.11a/b/g/n or 802.11a/b/g coverage that providesextended range. However, the number, thickness and location of walls, ceilings orother objects that the wireless signals must pass through may affect the range.Typical ranges vary depending on the types of materials and background RF(radio frequency) noise at your location. To maximize wireless range, follow thesebasic guidelines:1. Keep the number of walls and ceilings between the Array and yourreceiving devices to a minimum — each wall or ceiling can reduce the For a complete discussion of implementing Voice over Wi-Fi on the Array,see the Xirrus Voice over Wi-Fi Application Note in the Xirrus Library.
