Introduction 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.
Hardware Description LED Status Description Link On Green Indicates a valid 10/100 Mbps Ethernet cable link. Flashing Green Indicates that the access point is transmitting or receiving data on a 10/100 Mbps Ethernet LAN. Flashing rate is proportional to your network activity. On Green Indicates the 802.11a radio is enabled. Flashing Green Indicates that the access point is transmitting or receiving data through wireless links. Flashing rate is proportional to network activity.
Introduction 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. Power Connector The access point does not have a power switch.
Chapter 2: Hardware Installation To install the access point, follow the steps outlined below: 1. 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 4-3).
Hardware Installation • Using the mounting bracket, mark the position of the four screw holes on the wall or ceiling. For concrete or brick walls, you will need to drill holes and insert wall plugs for the screws. • Position the mounting bracket over the wall or ceiling screw holes, then insert the included screws and tighten them down to secure the bracket firmly to the wall or ceiling. • Attach the access point to the mounting bracket.
Hardware Installation 3. 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. 4. 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.

Chapter 3: Access Point Configuration This chapter describes how to use the Web interface to perform initial configuration of the access point. You can manage the RoamAbout Access Point 4102 with: • The Command Line Interface (CLI) accessed through a direct connection to the console port. Refer to the RoamAbout RBT-4102 Wireless Access Point Configuration Guide to view a complete list of all of the CLI commands, and how to use them. • The web interface accessed through a web browser (Internet Explorer V5.
Access Point Configuration • Set the emulation mode to VT100. • When using HyperTerminal, select Terminal keys, not Windows keys. Note: When using HyperTerminal with Microsoft® Windows® 2000, make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal’s VT100 emulation. Go to www.microsoft.com for information on Windows 2000 service packs. 4.

Chapter 4: Network Configuration Wireless networks support a standalone configuration as well as an integrated configuration with 10/100 Mbps Ethernet LANs. The RoamAbout RBT-4102, RBT-4102-BG, and the RBT-4102-EU, also provide bridging services that can be configured independently on either the 5 GHz or 2.4 GHz radio interfaces.
Network Configuration Network Topologies 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.
Network Topologies 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.
Network Configuration 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.
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.

Appendix B: Cables and Pinouts 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. Note: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.
