Configuring the external antenna model
This section introduces the external antenna portfolio available for the WLAN 2300 system AP-2330/2330A/
2330B and Series 2332 Access Points.
• The portfolio includes 802.11b/g (2.4GHz), 802.11a (5GHz) and 802.11a/b/g (2.4/5GHz) models.
• The addition of external antennas to the WLAN 2300 system portfolio improves overall system value:
• Improved deployment flexibility – Planners can choose an antenna pattern that meets
coverage requirements while allowing for convenient AP placement and installation.
• Improved coverage and performance – External antennas allow planners to optimize
coverage and deliver higher available data rates to user concentrations.
• Can provide a low cost fix for trouble spots - Appropriately outfitting existing APs with
external antennas can greatly improve coverage and available data rates in areas that are
not adequately serviced.
• Increased security – Perimeter access points outfitted with directional external antennas
can focus energy inwards and increase security by preventing signal “leakage” outside the
office.
• Improved aesthetics – External antennas feature a 3 foot cable that allows the connected
access point to be installed out-of-sight.
• Lower cost of coverage – External antennas improve overall system efficiency by
effectively directing available energy to where it’s needed. This ensures overall system
utility is maximized for any installation.
The WLAN 2300 series external antennas are the only external antennas certified by Nortel for use with
WLAN 2300 systems. WLAN Access Points 2330/2330A/2330B and Series 2332 outfitted with non-certi-
fied external antenna are not supported under Nortel support agreements.
The WLAN 2300 system must be upgraded to WSS Software v4.1 (or later) and WMS v4.1 (or later). Support
for Series 2332 access points and their associated external antennas requires WSS Software v6.0 (or later) and
WMS v6.0 (or later). This upgrade includes antenna pattern libraries for the WLAN 2300 series external
antenna portfolio and allows the system to
• Accurately predict RF environments when using the WMS planning tool to calculate
coverage provided by access points equipped with external antennas.
• Correctly interpret received signal strength measurements from APs with external
antennas when calculating rogue device or client location.
The WLAN 2300 system external antenna portfolio is sourced from Cushcraft, a world leader in the develop-
ment of advanced antenna technology and products.
• The Cushcraft products have been modified for compatibility with the AP-2330/2330A/
2330B and Series 2332 Access Points.
• Nortel versions are equipped with an R-SMA (reverse SMA) type connector to comply
with industry regulatory quality standards and correctly interface with the AP-2330/
2330A/2330B and Series 2332 Access Points.
• The Cushcraft model numbers presented throughout this bulletin refer to the Nortel
specific versions and may not exactly match similar versions promoted on Cushcraft’s
website or other product materials.
