Configuring the Altitude AP
NOTE
The Outdoor AP can also be deployed in indoor environments.
NOTE
The configuration process is identical for Altitude APs, Outdoor APs, and Altitude 802.11n APs, unless specified
otherwise.
NOTE
The radio specifications of the Outdoor AP is identical to the Altitude AP. For more information, see

Altitude 802.11n AP
The Altitude 802.11n AP is an IEEE 802.11n (draft)-compliant access point that offers significant increase
in data throughput and coverage range without additional bandwidth or transmit power. With both 2.4
GHz and 5 GHz 802.11n (draft) standard radio modules, the Altitude 802.11n AP delivers total data
rates of up to 300 Mbps. Given that the improved throughput of 300 Mbps will be spread over a
number of simultaneous users, the performance of the Altitude 802.11n AP will be close to that of a
wired 100 Mbps Ethernet connection - the standard for desktop connectivity. With the Altitude 802.11n
AP, mobile users get a similar experience to wired networks while accessing high-bandwidth data,
voice, and video applications.
The Wireless 802.11n AP can achieve link rates of up to 300 Mbps. To achieve this high link rate, specific
items need to be configured through the Summit WM Graphical User Interface. For more information,
see
"Achieving high throughput with the Wireless 802.11n AP" on page
NOTE
The Altitude 802.11n AP is backward-compatible with existing 802.11a/b/g networks.
NOTE
The Altitude 802.11n AP cannot operate as a stand-alone access point.
MIMO
The mainstay of 802.11 AP is MIMO (multiple input, multiple output) - a technology that uses advanced
signal processing with multiple antennas to improve the throughput. MIMO takes the advantage of
multipath propagation to decrease packet retries to improve the fidelity of the wireless network.
The 802.11n AP's MIMO radio sends out one or two radio signals through its three antennas. Each of
these signals is called a spatial stream. Because the location of the antennas on the 802.11n AP is spaced
out, each spatial stream follows a slightly different path to the client device. Furthermore, the three
spatial streams get multiplied into several streams as they bounce off the obstructions in the vicinity.
