Overview
Wireless networks support a standalone configuration as well as an integrated configuration with
10/100 Mbps Ethernet LANs. The RoamAbout RBT‐4102‐LIC, also provides bridging services that
can be configured independently on either the 5 GHz or 2.4 GHz radio interfaces.
Access points can be deployed to support wireless clients and connect wired LANs in the
following configurations:
•
Ad hoc for departmental, SOHO or enterprise LANs
•
Infrastructure for wireless LANs
•
Infrastructure wireless LAN for roaming wireless PCs
•
Infrastructure wireless bridge to connect wired LANs
•
The 802.11b and 802.11g frequency band which operates at 2.4 GHz can easily encounter
interference from other 2.4 GHz devices, such as other 802.11b or g wireless devices, cordless
phones and microwave ovens. If you experience poor wireless LAN performance, try the
following measures:
•
Limit any possible sources of radio interference within the service area
•
Increase the distance between neighboring access points
•
Decrease the signal strength of neighboring access points.
•
Increase the channel separation of neighboring access points (for example, up to 3 channels of
separation for 802.11b, or up to 4 channels for 802.11a, or up to 5 channels for 802.11g)

Ad Hoc Wireless LAN (no Access Point)
An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter,
connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc
wireless LAN must therefore be configured to the same radio channel. An ad hoc wireless LAN
can be used for a branch office or SOHO operation.

Infrastructure Wireless LAN
The access point also provides access to a wired LAN for wireless workstations. An integrated
wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of
a group of wireless PC users, and an access point that is directly connected to the wired LAN.
Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or
access other computers or network resources in the wired LAN infrastructure via the access point.
The infrastructure configuration not only extends the accessibility of wireless PCs to the wired
LAN, but also increases the effective wireless transmission range for wireless PCs by passing their
signal through one or more access points.
A wireless infrastructure can be used for access to a central database, or for connection between
mobile workers, as shown in the following figure.

Network Configuration
Network Topologies
Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) defines the communications domain for each access point and its
associated wireless clients. The BSS ID is a 48‐bit binary number based on the access point’s
wireless MAC address, and is set automatically and transparently as clients associate with the
access point. The BSS ID is used in frames sent between the access point and its clients to identify
traffic in the service area.
The BSS ID is only set by the access point, never by its clients. The clients only need to set the
Service Set Identifier (SSID) that identifies the service set provided by one or more access points.
The SSID can be manually configured by the clients, can be detected in an access point’s beacon, or
can be obtained by querying for the identity of the nearest access point. For clients that do not
need to roam, set the SSID for the wireless card to that used by the access point to which you want
to connect.
A wireless infrastructure can also support roaming for mobile workers. More than one access
point can be configured to create an Extended Service Set (ESS). By placing the access points so
that a continuous coverage area is created, wireless users within this ESS can roam freely. All
wireless network cards and adapters and wireless access points within a specific ESS must be
configured with the same SSID.

Network Topologies
Infrastructure Wireless Bridge
The IEEE 802.11 standard defines a Wireless Distribution System (WDS) for bridge connections
between BSS areas (access points). The access point uses WDS to forward traffic on links between
units.
The access point supports WDS bridge links on either the 5 GHz (802.11a) or 2.4 GHz (802.11b/g)
bands and can be used with various external antennas to offer flexible deployment options.
Up to six WDS bridge links can be specified for each unit in the wireless bridge network. One unit
only must be configured as the “root bridge” in the wireless network. The root bridge should be
the unit connected to the main core of the wired LAN. Other bridges must configure one “parent”
link to the root bridge or to a bridge connected to the root bridge. The other five available WDS
links can be specified as “child” links to other bridges. This forms a tiered‐star topology for the
wireless bridge network.
When using WDS on a radio band, only wireless bridge units can associate to each other. Wireless
clients can only associate with the access point using a radio band set to access point.

Features
The RoamAbout RBT‐4102‐LIC is an IEEE 802.11a/b/g access point that provides transparent,
wireless high‐speed data communications between the wired LAN and fixed or mobile devices
equipped with an 802.11a, 802.11b, or 802.11g wireless adapter.
This solution offers fast, reliable wireless connectivity with considerable cost savings over wired
LANs (which include long‐term maintenance overhead for cabling). Using 802.11a and 802.11g
technology, these access points can easily replace a 10 Mbps Ethernet connection or seamlessly
integrate into a 10/100 Mbps Ethernet LAN.
The RBT‐4102‐LIC supports up to eight Virtual Access Points per physical radio interface, that is
eight on the 802.11a radio, and eight on the 802.11g radio. This allows traffic to be separated for
different user groups using an access point that services one area. For each VAP, different security
settings, VLAN assignments, and other parameters can be applied.
Each radio interface on the RBT‐4102‐LIC can operate in one of three modes:
•
Access Point – Providing connectivity to wireless clients in the service area.
•
Bridge (Point‐to‐Point) – Providing links to other access points in “Bridge” or “Root Bridge”
mode connecting wired LAN segments.
•
Root Bridge (Point‐to‐Multipoint) – Providing links to other access points in “Bridge” mode
connecting wired LAN segments. Only one unit in the wireless bridge network can be set to
“Root Bridge” mode.
In addition, the access point offers full network management capabilities through an easy to
configure web interface, a command line interface for initial configuration and troubleshooting,
and support for Simple Network Management tools.
Radio Characteristics – The IEEE 802.11a/g standard uses a radio modulation technique known as
Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/
CA). It operates at the 5 GHz Unlicensed National Information Infrastructure (UNII) band for
connections to 802.11a clients, and at 2.4 GHz for connections to 802.11g clients.
RBT-4102-LIC Access Point Installation Guide
2-1
Package Checklist
IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard. IEEE 802.11b also

Component Description
Antennas
The access point includes integrated diversity antennas for wireless communications. A diversity
antenna system uses two identical antennas to receive and transmit signals, helping to avoid
multipath fading effects. When receiving, the access point checks both antennas and selects the
one with the strongest signal. When transmitting, it will continue to use the antenna previously
selected for receiving. The access point never transmits from both antennas at the same time.
RBT-4102-LIC Access Point Installation Guide
2-3
Hardware Description
The antennas transmit the outgoing signal as a toroidal sphere (doughnut shaped), with the
coverage extending most in a direction perpendicular to the antenna. The antenna should be
adjusted to an angle that provides the appropiate coverage for the service area. For further
information, see “Position the Antennas” on page 3‐4.
External Antenna Connectors
The access point supports external antenna connections for both the 2.4 GHz and 5 GHz radios.
These antennas offer a variety of options for extending the radio range and shaping the coverge
area. For a list of external antennas, their model type and gain refer to “External Antennas” on
page C‐6.
For information on the external antennas available, refer to the following document on the
Enterasys Web site:

The access point includes a Kensington security slot on the rear panel. You can prevent
unauthorized removal of the access point by wrapping the Kensington security cable (not
provided) around an unmovable object, inserting the lock into the slot, and turning the key.
Console Port
This port is used to connect a console device to the access point through a serial cable. This
connection is described under “Console Port Pin Assignments” on page B‐4. The console device
can be a PC or workstation running a VT‐100 terminal emulator, or a VT‐100 terminal.
Ethernet Port
The access point has one 10BASE‐T/100BASE‐TX RJ‐45 port that can be attached directly to
10BASE‐T/100BASE‐TX LAN segments. These segments must conform to the IEEE 802.3 or 802.3u
specifications.
This port supports automatic MDI/MDI‐X operation, so you can use straight‐through cables for all
network connections to PCs, switches, or hubs.
The access point appears as an Ethernet node and performs a bridging function by moving
packets from the wired LAN to remote workstations on the wireless infrastructure.
Note: The RJ-45 port also supports Power over Ethernet (PoE) based on the IEEE 802.3af
standard. Refer to the description for the “Power Connector” for information on supplying power to
the access point’s network port from a network device, such as a switch, that provides Power over
Ethernet (PoE).
Reset Button
This button is used to reset the access point or restore the factory default configuration. If you hold
down the button for less than 5 seconds, the access point will perform a hardware reset. If you
hold down the button for 5 seconds or more, any configuration changes you may have made are
removed, and the factory default configuration is restored to the access point.

Hardware Description
Power Connector
The access point does not have a power switch. It is powered on when connected to the AC power
adapter, and the power adapter is connected to a power source. The power adapter automatically
adjusts to any voltage between 100~240 volts at 50 or 60 Hz. No voltage range settings are
required.
The access point may also receive Power over Ethernet (PoE) from a switch or other network
device that supplies power over the network cable based on the IEEE 802.3af standard.
Notes:
• The access point supports both endspan and midspan PoE.
• If the access point is connected to a PoE source device and also connected to a local power
source through the AC power adapter, AC power will be disabled.

Installation Requirements and Recommendations
Select a Site – Choose a proper place for the access point. In general, the best location is at the
center of your wireless coverage area, within line of sight of all wireless devices. Try to place the
access point in a position that can best cover its Basic Service Set (refer to “Infrastructure Wireless
LAN” on page 1‐2). For optimum performance, consider these points:
•
Mount the access point as high as possible above any obstructions in the coverage area.
•
Avoid mounting next to or near building support columns or other obstructions that may
cause reduced signal or null zones in parts of the coverage area.
•
Mount away from any signal absorbing or reflecting structures (such as those containing
metal).

Installing the Access Point
Installing the Access Point
1.
Mount the Access Point – The access point can be mounted on any horizontal surface or a
wall.
• Mounting on a Horizontal Surface – To keep the access point from sliding on the surface,
attach the four rubber feet provided in the accessory kit to the marked circles on the bottom
of the access point.
• Mounting on a Wall – To mount on a wall or ceiling you must first attach the mounting
bracket to the base of the access point. Align the two mounting slots on the bracket with the
raised attaching slats and screw the unit into place firmly.
Mounting Slots
Attaching Slats
Bottom of Access Point
The access point should be mounted only to a wall or wood surface that is at least 1/2‐inch
thick plywood or its equivalent. To mount the access point on a wall, always use its wall‐
mounting bracket. The access point must be mounted with the RJ‐45 cable connector oriented
upwards to ensure proper operation.
3-2

Installing the Access Point
2.
Using the mounting bracket, mark the position of the four screw holes on the wall. For
concrete or brick walls, you will need to drill holes and insert wall plugs for the screws.
3.
Position the mounting bracket over the wall screw holes, then insert the included screws and
tighten them down to secure the bracket firmly to the wall.
4.
Attach the access point to the mounting bracket. Line up the two mounting points on the
bracket with the two mounting slots on the bottom of the access point (see the following
figure). Place the mounting points of the bracket into the mounting slots of the bracket, slide it
into position so that the bracket fastening screw on the access point lines up with the tab on
the bracket. Then screw down the fastening screw to secure the access point to the bracket.

5.
Lock the Access Point in Place – To prevent unauthorized removal of the access point, you
can use a Kensington Slim MicroSaver security cable (not included) to attach the access point
to a fixed object.
6.
Connect the Power Cord – Connect the power adapter to the access point, and the power cord
to an AC power outlet. Otherwise, the access point can derive its operating power directly
from the RJ‐45 port when connected to a device that provides IEEE 802.3af compliant Power
over Ethernet (PoE).
Warning: Use ONLY the power adapter supplied with this access point. Otherwise, the
product may be damaged.
RBT-4102-LIC Access Point Installation Guide
3-3
Installing the Access Point
Note: If the access point is connected to both a PoE source device and an AC power
source, AC will be disabled.
7.
Observe the Self Test – When you power on the access point, verify that the Power indicator
stops flashing and remains on, and that the other indicators start functioning as described in
“LED Indicators” on page 2‐4.
If the PWR LED does not stop flashing, the self test has not completed correctly. Refer to
Appendix A, Diagnosing Access Point Indicators.
8.
Connect the Ethernet Cable – The access point can be wired to a 10/100 Mbps Ethernet
through a network device such as a hub or a switch. Connect your network to the RJ‐45 port
on the back panel with category 3, or 4 UTP Ethernet cable. When the access point and the
connected device are powered on, the Ethernet Link LED should light indicating a valid
network connection.
Note: The RJ-45 port on the access point supports automatic MDI/MDI-X operation, so you
can use straight-through cables for all network connections to PCs, switches, or hubs.
9.
Position the Antennas – Each antenna emits a radiation pattern that is toroidal (doughnut
shaped), with the coverage extending most in the direction perpendicular to the antenna.
Therefore, the antennas should be oriented so that the radio coverage pattern fills the
intended horizontal space. Also, the diversity antennas should both be positioned along the
same axes, providing the same coverage area. For example, if the access point is mounted on a
horizontal surface, both antennas should be positioned pointing vertically up to provide
optimum coverage.
10. Connect the Console Port – Connect the console cable (included with RBT‐4102‐LIC) to the
RS‐232 console port for accessing the command‐line interface. You can manage the access
point using the console port, the web interface, or SNMP management software, such as
Enterasys NetSight or HP’s OpenView.

Cables and Pin-outs
Twisted-Pair Cable Assignments
For 10/100BASE‐TX connections, a twisted‐pair cable must have two pairs of wires. Each wire pair
is identified by two different colors. For example, one wire might be green and the other, green
with white stripes. Also, an RJ‐45 connector must be attached to both ends of the cable.
Notes:
• Each wire pair must be attached to the RJ-45 connectors in a specific orientation. (Refer to
“Straight-Through Wiring” on page B-3 and “Crossover Wiring” on page B-4 for an explanation.)
• DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair cables with RJ-45
connectors that conform with FCC standards.
The following figure illustrates how the pins on the RJ‐45 connector are numbered. Be sure to hold
the connectors in the same orientation when attaching the wires to the pins.
RBT-4102-LIC Access Point Installation Guide

10/100BASE-TX Pin Assignments
Use unshielded twisted‐pair (UTP) or shielded twisted‐pair (STP) cable for RJ‐45 connections:
100‐ohm Category 3 or better cable for 10 Mbps connections. Also be sure that the length of any
twisted‐pair connection does not exceed 100 meters (328 feet).
The RJ‐45 port on the access point supports automatic MDI/MDI‐X operation, so you can use
straight‐through or crossover cables for all network connections to PCs, switches, or hubs. In
straight‐through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to
pins 1, 2, 3, and 6 at the other end of the cable.
