[. . . ] D-Link Unified Access System User Manual FCC Warning This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with this manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. CE Mark Warning This is a Class A product. [. . . ] The fields in Table 23 appear when you click the current channel or power setting for an AP on the Managed AP Advanced page. Table 23. Managed AP Channel/Power Adjust Field AP MAC Address Radio Description Shows the MAC address of the access point. The changes apply only to this radio. 120 © 2001- 2008 D-Link Corporation.

Managed AP Channel/Power Adjust Field Channel Status Description The status is one of the following: · · · Channel None Set Requested Set Complete The Channel defines the portion of the radio spectrum that the radio uses for transmitting and receiving. The range of channels and the default channel are determined by the Mode of the radio interface. IEEE 802. 11b/802. 11g modes (802. 11 b/g) support use of channels 1 through 11 inclusive, while IEEE 802. 11a mode supports a larger set of nonconsecutive channels (36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165). NOTE: The available channels depends on the country in which the APs operate. NOTE: For radios that use 802. 11a mode, some countries have a regulatory domain that requires radar detection. For these countries (based on the country code setting), the radio automatically uses the 802. 11h protocol for selecting the channel if radar is detected on the statically assigned channel. Interference can occur when multiple access points within range of each other are broadcasting on the same or overlapping channels. The impact of this interference on network performance can intensify during busy times when a large amount of data and media traffic is competing for bandwidth. If you select auto, the AP scans the RF area for occupied channels and selects a channel from the available non-interfering, or clear channels. If you specify a channel, make sure that the channel does not interfere with the channel that neighbor APs use. Power Status The status is one of the following: · · · None Set Requested Set Complete Power The power level affects how far an AP broadcasts its RF signal. If the power level is too low, wireless clients will not detect the signal or experience poor WLAN performance. If the power level is too high, the RF signal might interfere with other APs within range.
