Cisco® Aironet® 802.11n access points include the Cisco Aironet 1250 Series, 1260
Series, 3500e Series, 3600e Series, and 1550 Series. These access points require the
use of external antennas to make them fully functioning units. Although most existing
Cisco antennas can be used, Cisco has developed antennas specifically designed for
use with 802.11n access points to optimize performance. This document explains the
antenna options for the Cisco Aironet 802.11n access points.

Flexible Options
Cisco offers a variety of antennas that provide different mounting options and coverage
patterns. Customers can select an antenna that will increase the overall efficiency
and data rates of their wireless network, while accommodating specific deployment
conditions, including physical layout, distance, and aesthetics.

To optimize the overall performance of a Cisco wireless LAN, it is important to
understand how to maximize radio coverage with the appropriate antenna selection
and placement. Table 1 describes three antenna types available for use with the
802.11n access points.

Indoor/Outdoor Omnidirectional Antennas
Omnidirectional antennas are connected to the access point via short, attached
plenum cables. The antennas can be mounted to a ceiling and provide a large, circular
coverage area. These antennas can be used both indoors and outdoors (see Table 2
for specific details for usage) and are typically mounted on a ceiling or mast-pole.

Examples of places in which omnidirectional antennas are useful include warehouses,
manufacturing floors, and other large areas, as well as outdoor seating areas, such as
cafés or central gathering places for students. Omnidirectional antennas can also be
used to provide good coverage in a retail environment, both inside and outside, as well
as in areas where trucks or police cars park to upload data.
