Outdoor external antennas

This section introduces the outdoor external antenna portfolio available for the WLAN 2300 Series System AP
Access Points 2330A and AP 2330B. The portfolio includes 802.11b/g (2.4 GHz) and 802.11a (5.0 GHz)
models for outdoor use. The addition of outdoor external antennas to the WLAN 2300 Series 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.
• 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 outdoor external antennas are the only external antennas certified by Nortel for use
with WLAN 2300 Series systems. WLAN Access Points AP 2330A and AP 2330B that are outfitted with
non-certified outdoor external antennas are not supported under Nortel support agreements.
The WLAN 2300 Series system must be upgraded to WSS Software Release 5.0.11.4 or later and WMS
Software Release 5.0.11.3 or later. This upgrade includes antenna pattern libraries for the WLAN 2300 series
outdoor external antenna portfolio and allows the system to:
• Compensate for extension cable loss and lightning protection circuitry that is essential for operation in an
outdoor environment.
• Correctly interpret received signal strength measurements from APs with external antennas when calculating
rogue device or client location.
The WLAN 2300 Series System outdoor external antenna portfolio is sourced from Cushcraft, a world leader
in the development of advanced antenna technology and products.
• The Cushcraft products have been modified for compatibility with the AP Access Points 2330A and AP
2330B.
• Nortel versions are equipped with an R-SMA type connector to comply with Nortel's quality and regulatory
standards and correctly interface with the AP 2330A and AP 2330B Access Points.
