1INTRODUCTION
Enterasys Networks wireless technology has all of the benefits of a local
area network (LAN) without the constraints and expense of network
wiring.
Enterasys Networks 802.11a/b/g Wireless LAN products provide easy,
affordable, flexible ways to extend wireless networks to more users. This
guideshows how you can use the Enterasys Networks 802.11a/b/g Wireless
Ethernet Adapter in your office or classroom to connect groups of wired
Ethernet client devices to your wireless LAN.
Product Features The Enterasys Networks 802.11a/b/g Wireless Ethernet Adapter includes a
robust suite of standards-based security features, and supports wireless
network standards including 802.11a and 802.11g.
Security To protect sensitive data broadcast over the radio, Enterasys Networks
supports Wireless Equivalent Privacy (WEP) RC4 64-bit, 128-bit and
152-bit shared-key encryption. Enterasys Networks strengthens this basic
security mechanism with additional security features, including:
■MAC address access control lists
■IEEE 802.1x per-port user authentication with RADIUS server
authentication support
■Temporal Key Integrity Protocol (TKIP)
■Advanced Encryption Standard (AES)
■WiFi Protected Access (WPA)
■Extensible Authentication Protocol (EAP) support: EAP-TTLS and PEAP

7CHAPTER 1: INTRODUCTION
Wireless Network
Standards Understanding the characteristics of the 802.11a and 802.11g standards can help you make the best choice for your wireless implementation plans.
802.11a
Ratified in 2002, 802.11a is IEEE’s more recent wireless standard. It
operates at the 5 GHz band and supports data rates at up to 54 Mbps.
Because there are fewer devices in the 5 GHz band, there’s less potential for
RF interference. However, because it is at an entirely different radio spectrum,
it is not compatible with 802.11g.
The higher spectrum provides about 50 m (164 ft) of coverage—about
half what 802.11g offers.
Consider 802.11a when you need high throughput in a confined space
and you are:
■Running high-bandwidth applications like voice, video, or multimedia
over a wireless network that can benefit from a five-fold increase in
data throughput.
■Transferring large files like computer-aided design files, preprint
publishing documents or graphics files, such as MRI scans for medical
applications, that demand additional bandwidth.
■Supporting a dense user base confined to a small coverage area.
Because 802.11a has a greater number of non-overlapping channels,
you can pack more wireless devices in a tighter space.
802.11g
802.11g operates in the 2.4 GHz band at up to 54 Mbps. Ratified in
2003, it supports the widest coverage—up to 100 m (328 ft). However, is
subject to a greater risk of radio interference because it operates in the more
popular 2.4 GHz band.
802.11b operates at up to 11 Mbps and supports coverage up to 100 m
(328 ft).

Network Configuration and Planning8
Consider 802.11g when you need wider coverage and vendor
compatibility and you are:
■Maintaining support for existing 802.11b users and the existing
wireless investment while providing for expansion into 802.11g.
■Implementing a complete wireless LAN solution, including Ethernet
Adapters, gateways, access points and clients; Wi-Fi certification
guarantees compatibility among vendors.
■Providing access to hot spots in public spaces such as coffee shops or
university cafeterias.
Network
Configuration and
Planning
The Ethernet Adapter can operate in either infrastructure or ad-hoc
mode, and can support a stand-alone wireless network configuration or
an integrated configuration with 10/100 Mbps Ethernet LANs.
Operating in infrastructure mode and connected to an Ethernet hub, a
single Ethernet Adapter can combine up to 16 client devices—such as
computers with network adapters and printers—into a multiclient
workgroup. The workgroup associates with the wired network through a
wireless LAN access point such as the Enterasys Networks 802.11a/b/g
Wireless LAN Access Point. Infrastructure configurations extend your
wireless LAN to devices that would otherwise have to be connected to
the wired network.
Operating in ad-hoc mode, two or more Ethernet Adapters can associate
among themselves and communicate with one another at close range
without an access point. You may wish to set up an ad-hoc network, for
example, if a group is working away from the office, or if a group in the
office needs to share files apart from the wired LAN.

9 CHAPTER 1: INTRODUCTION
Example
Configurations The following examples illustrate ways you can use the Ethernet Adapter to
configure Ethernet client devices into workgroups. (Details for setting up
specific configurations are in “Installing the Ethernet Adapter” on page 11.)
Wireless Infrastructure Network
You can connect several computers, including those with non-Windows
operating systems, and network printers, as shown in Figure 1.
Figure 1 Wireless Infrastructure Network
Workgroup Ad-Hoc Network
You can provide flexible wireless network association for small groups in
areas that cannot be wired, as shown in Figure 2.

Observing Safety
Precautions This equipment must be installed in compliance with local and national
building codes, regulatory restrictions, and FCC rules. For the safety of
people and equipment, only professional network personnel should
install the Ethernet Adapter.
WARNING: To comply with FCC radio frequency (RF) exposure limits, a
minimum body-to-antenna distance of 20 cm (8 in.) must be maintained
when the Ethernet Adapter is operational.
WARNING: To avoid possible injury or damage to equipment, you must
use either the provided power supply or power supply equipment that is
safety certified according to UL, CSA, IEC, or other applicable national or
international safety requirements for the country of use. All references to
power supply in this document refer to equipment meeting these
requirements.
WARNUNG: In Übereinstimmung mit den von der FCC (Federal
Communications Commission) festgelegten Grenzwerten für die
Einwirkung von Radiowellen muss bei Betrieb des Ethernet-Adapters der
Abstand zwischen Körper und Antenne 20 cm betragen.
WARNUNG: Zur Vermeidung möglicher Verletzungen oder Schäden am

Alle Verweise auf Netzteile in diesem Dokument beziehen sich auf
Netzgeräte, die diesen Anforderungen entsprechen.
CAUTION: The Enterasys Networks power supply (part number
61-0107-000) input relies on a 16A rated building fuse or circuit
protector for short circuit protection of the line to neutral conductors.
VORSICHT: Der Eingang des Enterasys Networks-Netzteils (Teilenummer

eine 16-A-Sicherung oder eine Überstromsicherung.
Deciding Where to
Place the Ethernet
Adapter
Place the Ethernet Adapter in a dry, clean location near the hub,
computer, or printer that will be connected to the Ethernet Adapter. The
location must have a power source and be within the following distance
of a Wi-Fi compliant wireless LAN access point or ad-hoc wireless station:
■For 802.11a compatibility, place the Ethernet Adapter within 50 m
(164 ft) of a Wi-Fi compliant wireless LAN access point.
■For 802.11b/g compatibility, place the Ethernet Adapter within 100 m
(328 ft) of a Wi-Fi compliant wireless LAN access point.
The location should be away from transformers, heavy-duty motors,
fluorescent lights, microwave ovens, refrigerators, or other equipment
that could cause radio signal interference.
Wall-Mounting the
Ethernet Adapter The Ethernet Adapter comes with two plastic anchors and two flat head mounting screws for mounting on a wall.

13 CHAPTER 2: INSTALLING THE ETHERNET ADAPTER
To wall-mount the Ethernet Adapter:
11 Place the two plastic anchors into a wall, then place two flat head
mounting screws inside the plastic anchors, as shown in Figure 4.
Figure 4 Place the screw on the wall
2Place the Ethernet Adapter onto the wall, as shown in Figure 5.
Figure 5 Place the unit onto the wall
CAUTION: Do not place the Ethernet Adapter on any type of metal
surface. Select a location that is clear of obstructions and provides good
reception.
VORSICHT: Legen Sie den Ethernet-Adapter nicht auf Metallflächen ab.
Wählen Sie einen Ort ohne Störungen und mit gutem Empfang aus.
