Wireless LAN Array24 Installing the Xirrus ArrayPlanning Your InstallationThis section provides guidelines and examples to help you plan your XirrusArray 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.General Deployment ConsiderationsThe Xirrus Array’s unique multi-radio architecture generates 360 degrees ofsectored high-gain 802.11a/b/g coverage that provides extended range. However,the number, thickness and location of walls, ceilings or other objects that thewireless signals must pass through may affect the range. Typical ranges varydepending on the types of materials and background RF (radio frequency) noiseat your location. To maximize wireless range, follow these basic guidelines:1. Keep the number of walls and ceilings between the Array and yourreceiving devices to a minimum—each wall or ceiling can reduce thewireless range from between 3 and 90 feet (1 to 30 meters). Position yourdevices so that the number of walls or ceilings is minimized.2. Be aware of the direct line between each device. For example, a wall thatis 1.5 feet thick (half a meter) at 90° is actually almost 3 feet thick (or 1meter) when viewed at a 45° angle. At an acute 2° degree angle the samewall is over 42 feet (or 14 meters) thick! For best reception, try to ensurethat your wireless devices are positioned so that signals will travelstraight through a wall or ceiling.Figure 8.
