Multiple Mounting Options
The access point attaches to a wall, mounts under a ceiling or above a ceiling (attic). Choose a mounting
option based on the physical environment of the coverage area. Do not mount the Access Point in a
location that has not been approved in a radio coverage site survey.
For detailed information on the mounting options available , see “Mounting an Altitude 4700 Series
Access Point” on page 50 .
Antenna Support for 2.4 GHz and 5 GHz Radios
The Access Point supports several 802.11a/n and 802.11b/g/n radio antennas. Select the antenna best
suited to the radio transmission requirements of your coverage area.
For a comprehensive overview of the antennas and associated components supported by the Extreme
Networks access point family, see the
Altitude 35xx/46xx/47xx AP Antenna Selection Guide, Rev.xx .
Sixteen Configurable WLANs
A Wireless Local Area Network (WLAN) is a data-communications system that flexibly extends the
functionalities of a wired LAN. A WLAN does not require lining up devices for line-of-sight
transmission, and are thus, desirable for wireless networking. Roaming users can be handed off from
one Access Point to another like a cellular phone system. WLANs can therefore be configured around
the needs of specific groups of users, even when they are not in physical proximity. Sixteen WLANs are
configurable on each Access Point.
To enable and configure WLANs on an Access Point radio, see “Enabling Wireless LANs (WLANs)” on
page 146 .
Support for 4 BSSIDs per Radio
The Access Point supports four BSSIDs per radio. Each BSSID has a corresponding MAC address. The
first MAC address corresponds to BSSID #1. The MAC addresses for the other three BSSIDs (BSSIDs #2,
#3, #4) are derived by adding 1, 2, 3, respectively, to the radio MAC address.
If the radio MAC address displayed on the Radio Settings screen is 00:23:68:72:20:DC, then the BSSIDs
for that radio will have the following MAC addresses:
For detailed information on strategically mapping BSSIDs to WLANs, see “Configuring the 802.11a/n or
802.11b/g/n Radio” on page 174 . For information on Access Point MAC address assignments, see
“MAC Address Assignment” on page 43 .
BSSID MAC Address Hexadecimal Addition
BSSID #1 00:23:68:72:20:DC Same as Radio MAC address
BSSID #2 00:23:68:72:20:DD Radio MAC a1
BSSID #3 00:23:68:72:20:DE Radio MAC a2
BSSID #4 00:23:68:72:20:DF Radio MAC a3
