Introduction 1Chapter 17/29/03 FINAL DRAFT—CONFIDENTIALCHAPTER 1IntroductionThe Aruba 52 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 52 provides transparent, secure, high-speed data com-munications between wireless network devices (fixed, portable, or mobile computers with IEEE 802.11a, 802.11b, or 802.11g wireless adapters) and the wired LAN.As a wireless air monitor, a uniquely Aruba feature, the Aruba 52 enhances wireless networks by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies, balancing wireless traffic load, self-healing coverage gaps, and more.Product FeatureszWireless dual-band transceiverzDual, omnidirectional antennas for reception diversityzProtocol-independent networking functionalityz802.11a – up to 54 Mbps data rate per channel: offers a high data rate and reliable wireless connectivityz802.11b – up to 11 Mbps data rate per channel: provides an alternative to wired LANs that can dramatically cut costsz802.11g – up to 54 Mbps data rate per channel: backwards compatible with 802.11bzCompatible with IEEE 802.3af Power Over Ethernet (POE)zSeamless connectivity to wired LANs augment existing networks quickly and easilyzCan be centrally managed, configured, and upgraded through the Aruba WLAN Switch to take advantage of network changes and security improvements
7/29/03 FINAL DRAFT—CONFIDENTIAL2Aruba52 Part 0500007BInstallation Guide August 2003Ethernet CompatibilityThe Aruba 52 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 CharacteristicsFor IEEE 802.11a operation, the Aruba 52 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).For IEEE 802.11b operation, the Aruba 52 uses the IEEE 802.11 High-Rate Direct Sequence (HRDS) specification, and a shared collision domain (CSMA/CA). It operates in the 2.4GHz Industrial/Scientific/Medical (ISM) band. The ISM band is available worldwide for unli-censed use. Data is transmitted at speeds of up to 11 Mbps.For IEEE 802.11g operation, the Aruba 52 uses ODFM and a shared collision domain (CSMA/CA). It operates in the 2.4GHz Industrial/Scientific/Medical (ISM) band. The ISM band is available worldwide for unlicensed use. Data is transmitted at speeds of up to 54 Mbps.Power Over EthernetThe Aruba 52 supports the IEEE 802.3af standard for Power Over Ethernet (POE). With this feature, the Aruba 52 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 52 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).
