Basics of Nortel WLAN 2300 Series Outdoor Solution 17Nortel WLAN 2300 Series Outdoor Solution GuideDynamic Frequency Selection (DFS)This device implements a DFS feature in accordance with the limits in EN 301-893v1.2.3, Section 4.6 andAnnex D, Tables D.1, D.2 and D.4 for a device operating in the mode defined as "Master". Section 4.6, Tables6 and 7 of this document define the requirements prior to using a channel and during normal operation for aMaster device (i.e., Interference Detection Threshold, Channel Availability Check Time, Uniform Spreading,Channel Closing Transmission Time and Channel Move Time). This product qualifies for this category sincethe maximum achievable transmit power is greater than 23 dBm per the requirements of Table D.2 in Annex Dof the standard.IEEE 802.11a operation in the 5250 to 5350 MHz and 5470 to 5725 MHz frequency bands is governed byETSI EN 301-893v1.2.3 and the R&TTE Directive 1999/5/EC. Effective March 31, 2008, EN 301-893 v1.2.3will be replaced by EN 301-893v1.3.1. The AP-2330B access point will meet compliance with EN301-893v1.3.1 by disabling operation, via software, in the 5250 to 5350 MHz and 5470 to 5725 MHzfrequency bands because it cannot meet the DFS requirements as outlined in EN 301-893v1.3.1.Transmit Power Control (TPC)European Regulatory requirements specify that wireless devices must employ Transmit Power Control (TPC)to reduce the potential for interference to other communication systems operating in the 5 GHz frequencybands. This device includes a provision for adjustment of Transmit Power in accordance with the limits in EN301-893v1.2.3, Sections 4.3.1 and 4.3.2.Korea MIC Compliance StatementPossible radio wave interference during operation of concerned radio equipment.
