Operation Using the 5.15 to 5.25 GHz, 5.25 to 5.35 GHz, and 5.470 to 5.725 GHz Channels in
the European Community
To remain in conformance with European National spectrum usage laws, follow the channel limitations associated with
the 5 GHz bands as specified in this document. The professional installer should verify the current channel of operation
and the expected transmit power level of the WLAN Access Point 2332-E1 or related Series 2332 access point to
confirm that the device is operating in conformance with the spectrum usage rules for the European Community country
where the unit is being installed. If operation is occurring outside of the allowable frequencies or above the power
levels, as indicated in this guide, then operation of the product must cease immediately and the installer must
consult with the local technical support staff responsible for the wireless network.
This device is intended to be operated in all countries of the European Community. Additional restrictions of use for the
2332-E1 and related Series 2332 access points within the European Community countries in the 5.15 to 5.25 GHz, 5.25
to 5.35 GHz, and 5.470 to 5.725 GHz bands are listed below.
• This device is restricted to indoor use only when operated in the European Community using the
5.15-5.25 GHz and 5.25-5.35 GHz bands, which includes channels 36, 40, 44, 48, 52, 56, 60 & 64.
• The 5 GHz Turbo Mode feature is not allowed for operation in any European Community country.
• Operation for the 2332-E1 is restricted to the 5.15 to 5.25 GHz band. No operation is permitted in either the
5.25 to 5.35 GHz or 5.470 to 5.725 GHz bands because the device is noncompliant with the DFS requirements
stated in EN 301-893 v1.3.1.
• In Italy and Latvia the end-user must apply for a license from the national spectrum authority to operate this
device outdoors. Please consult the Nortel WLAN 2300 Series Outdoor Solutions Guide for further infor-
mation regarding restrictions and operating conditions for outdoor configurations.
Dynamic Frequency Selection (DFS)
The 2332-E1 and related Series 2332 access points implement a DFS feature in accordance with the limits in EN
301-893v1.2.3, Section 4.6 and Annex D, Tables D.1, D.2 & D.4 for a device operating in the mode defined as "Master".
Section 4.6, Tables 6 and 7 of this document define the requirements prior to using a channel and during normal
operation for a Master 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 since
the maximum achievable transmit power is greater than 23 dBm per the requirements of Table D.2 in Annex D of the
standard.
IEEE 802.11a operation in the 5250 to 5350 MHz and 5470 to 5725 MHz frequency bands is governed by ETSI EN
301-893v1.2.3 and the R&TTE Directive 1999/5/EC. Effective March 31, 2008, EN 301-893 v1.2.3 will be replaced by
EN 301-893v1.3.1. The 2332-E1 access point will meet compliance with EN 301-893v1.3.1 by disabling operation, via
software, in the 5250 to 5350 MHz and 5470 to 5725 MHz frequency 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 frequency bands. This device
includes a provision for adjustment of Transmit Power in accordance with the limits in EN 301-893v1.2.3, Sections
4.3.1 and 4.3.2.
