CHAPTER 1
Introduction
The Aruba 50 is part of a comprehensive wireless network solution. The device works in con-
junction with the Aruba 5000 WLAN Switch and can act as a wireless access point or air mon-
itor.
As a wireless access point, the Aruba 50 provides transparent, secure, high-speed data com-
munications between wireless network devices (fixed, portable, or mobile computers with
IEEE 802.11a or IEEE 802.11b wireless adapters) and the wired LAN.
As a wireless air monitor, a uniquely Aruba feature, the Aruba 50 enhances wireless networks
by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies,
balancing wireless traffic load, self-healing coverage gaps, and more.

Ethernet Compatibility
The Aruba 50 attaches to 10/100 Mbps Ethernet (FE) LAN segments that utilize
10Base-T/100Base-TX (twisted-pair) wiring. The device appears as an Ethernet node and
performs a routing function by moving packets between the wired LAN and remote worksta-
tions on the wireless infrastructure.
Radio Characteristics
For IEEE 802.11a operation, the Aruba 50 uses a radio modulation technique known as
Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain
(CSMA/CA). It operates in the 5GHz Unlicensed National Information Infrastructure
(UNII) band. Data is transmitted over a half-duplex radio channel operating at up to 54
Megabits per second (Mbps), and with a maximum operating range up to 503 m (1650 ft.).
Power Over Ethernet
The Aruba 50 supports the IEEE 802.3af standard for Power Over Ethernet (POE). With this
feature, the Aruba 50 can accept electrical power from a compatible POE-capable device to
which it is connected, directly over the FE cable. POE eliminates the need to provide separate
power outlets in environments that are difficult or undesirable to wire for electricity.
The Aruba 50 supports POE only when the FE port is connected to an IEEE 802.3af compli-
ant device (such as the Aruba 5000 WS-5032 Line Card).
Power Over Ethernet
The Aruba 50 supports the IEEE 802.3af standard for Power Over Ethernet (POE). With this
feature, the Aruba 50 can accept electrical power from a compatible POE-capable device to
which it is connected, directly over the FE cable. POE eliminates the need to provide separate
power outlets in environments that are difficult or undesirable to wire for electricity.
The Aruba 50 supports POE only when the FE port is connected to an IEEE 802.3af compliant
device (such as the Aruba 5000 WS-5032 Line Card).
