Sample text

5 meters (1 to 8 feet) apart. 15 meters (6 inches) do not experience the diversity needed to quash multipath distortion. The farther apart you locate the antennas, the more disparate the areas the antennas cover. If they are too far apart, the antennas cover different clients. Whenever the AP decides to switch to the other antenna, the group of clients covered is cut off, and vice versa. Diversity relies on the antennas to cover the same radio cell. Upgrading Antennas There will likely come a time when you need an additional antenna for your WLAN.

11g coverage These devices support Wi-Fi Protected Access (WPA) and WPA2. 1X authentication, which includes LEAP, EAP-TLS, PEAP-GTC, EAP-FAST, and PEAP-MSCHAP V2. Wireless security is explored in Chapter 4. In addition, RADIUS servers can be used for strong security and user management. 11a technology, shown in Figure 1-18. 11a AP or the Aironet 1130AG AP. Figure 1-18. 11a functionality, it operates at speeds of up to 54 Mbps in the 5-GHz band. Data rates can be reduced to extend the device's range.

Interference When you deal with interference, it is best handled if you start with a site survey. The mechanics of site surveys are covered in Chapter 5, "Installing and Configuring Access Points," but, in essence, a site survey involves checking your environment for sources of interference and the best placement of Wi-Fi equipment. If you connect outdoors, don't forget to factor in weather conditions and trees. A wireless bridge that works well on a clear, beautiful day might encounter retries and other performance issues when it rains, snows, or is foggy.
