MIMO low gain omnidirectional antenna options for the Cisco 802.11n Series APs are shown in Table 7.
If the Cisco Aironet 1250, 1260, or 3500e Series AP are to be used, there are several external omnidirectional
antenna options to allow broader mounting options and to meet differing aesthetic requirements. Consult the
Cisco Aironet Antenna Reference Guide
for full details.

Omnidirectional Antenna Options for Cisco 802.11n Series APs
Using 802.11n capable radios is a fundamental design consideration for today’s high client density environments.
The above advantages, especially in a mixed environment, lend themselves well to a high-density deployment.

Directional Antennas
It is not always going to be possible to solve challenges in a high-density environment using strictly
omnidirectional antennas. If a WLAN requires channel reuse within the same floor space or if coverage is required
for non-standard areas such as indoor or outdoor arenas, mounting options for a usable design may be limited.
Therefore directional antennas come in many coverage patterns that are more suited to challenging environments
where an omnidirectional will not be adequate.
