2. Quick Start Setup and
Operation for the Hub
Use the following steps to get up and running with your 3-Mbps Wireless Ethernet Hub. (For more detailed procedures, see Section 4.1.)
1. Position the Hub in a high, central location, well away from moving objects and metal furniture.
NOTE
When using more than one Hub, make sure to define different hopping sequences for each Access Point. See Chapter 5.
2.Connect the power transformer to a 110/220 VAC power supply and to the DC input socket on the Hub.
3.Connect the Hub to the Ethernet backbone by attaching one end of a regular, uncrossed 10BASE-T cable (not supplied) to the RJ-45 port on the back panel of the Hub (marked UTP). Attach the other end of the connector cable to any available Ethernet hub port.
14

3.Introduction
3.1The 3-Mbps Wireless Ethernet Product Line
The Wireless Ethernet product line contains the following units:
•Wireless Ethernet Hub (LW001A, LW005A, or LW007A)
•Wireless Ethernet Workstation Adapter (LW002A or LW008A)
•Wireless Ethernet Four-Port Workstation Adapter (LW003A or LW009A)
•Wireless Ethernet Wireless Bridge (LW004A or LW010A)
WIRELESS ETHERNET HUB (LW001A, LW005A, OR LW007A)
The Wireless Ethernet Hub (LW001A) is a wireless Hub that provides access for the wireless workstation users into wired Ethernet LANs.
The Wireless Ethernet Hub for PCMCIA (LW005A) is the same as the LW001A, except that the LW005A must be used with the PCMCIA Wireless Adapter (LW006A). Any reference in this manual to the LW001A also applies to the LW005A.
16
3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES
The LW001A and LW007A function exactly the same way, but the LW001A has permanently attached antennas, and the LW007A has detachable antennas. A third Hub, LW005A (which is covered in a separate manual), has the same hardware as the LW007A, but different software. It works with portable computers equipped with the PCMCIA Wireless Adapter (LW006A) to connect to wired Ethernet LANs.
The Hub also contains the coordinating function that enables workstations to communicate through it to one another inside the cell coverage area, even though they may not be in direct line of sight. Mobile workstations can roam from one Hub to another that belongs to the same extended wireless network. When Hubs are set up in such a way that their coverage areas overlap one another, users may roam seamlessly from cell to cell. The Workstation Adapters “decide” when a mobile user becomes disassociated from one Hub and associated with another.
This process is fully transparent, requires no user intervention, and involves no loss of data packets.
You can position multiple Hubs in locations where you expect heavy network traffic. This will increase the throughput capacity in the areas where you most need it.
17

WIRELESS ETHERNET WORKSTATION ADAPTER (LW002A OR
LW008A)
The LW002A is a wireless LAN adapter that converts any 10BASE-T Ethernet equipped computer (including PCs, X-Terminals, Digital™, Sun, HP®, IBM®, and Apple®), into a wireless LAN station. The LW002A is transparent to the computer’s hardware and software. This enables plug-and-play installation.
The LW002A and LW008A function exactly the same way, but the LW002A has permanently attached antennas, and the LW008A has detachable antennas.
The Workstation Adapter can communicate with any other workstation adapters in its coverage area, or via the Wireless Ethernet Hub to all of the network resources such as file servers, printers and shared databases.
The Workstation Adapter contains an embedded SNMP agent that lets you effectively manage it from the LAN Management Information Base. Software upgrades are downloaded by TFTP.
20

The network stays connected while you roam between overlapping coverage areas; plus, you get continuous transmission and reception while moving at high speed without losing or duplicating data packets.

3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES
WIRELESS ETHERNET 4-PORT WORKSTATION ADAPTER
(LW003A OR LW009A)
The Wireless Ethernet 4-Port Workstation Adapter (LW003A) is a wireless LAN adapter that connects a workgroup of up to four 10BASE-T Ethernet equipped workstations to the wireless LAN. Workstations that can be converted by the 4-Port Workstation Adapter into wireless LAN stations include PCs,
X-Terminals, Digital, SUN, HP, IBM and Apple computers. The Adapter is transparent to the workgroup computers’ hardware and software.
The LW003A and LW009A function exactly the same, but the LW003A has permanently attached antennas, and the LW009A has detachable antennas.
The 4-Port Workstation Adapter lets connected workstations communicate with other Wireless Ethernet stations in its coverage area, or via the Wireless Ethernet Hub (LW001A or LW007A) to all of the network resources such as file servers, printers and shared databases. The 4-Port Workstation Adapter also allows highly efficient and fast wired communication between the connected workstations.
22
3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES
The 4-Port Workstation Adapter contains an embedded SNMP agent and software downloading capabilities that let you manage it from the LAN Management Information Base.

3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES
WIRELESS BRIDGE (LW004A OR LW010A)
The Wireless Bridge (LW004A) is a high-speed, widerange wireless LAN bridge that provides connectivity to remote Ethernet networks.
The LW004A and LW010A function exactly the same way, but the LW004A has permanently attached antennas, and the LW010A has detachable antennas.
The LW004A communicates with the Wireless Ethernet Hubs (LW001A) of the remote LANs, and the LW010A communicates with the Wireless Ethernet Hub (LW007A) of the remote LANs. This effectively creates an extended wireless network spanning sites situated up to 7 miles apart. In this way a central Ethernet LAN may be connected with one or more branch office LANs.
The Wireless Bridge also allows connectivity between a wireless LAN and individual workstations or workgroups located outside the LAN.
WIRELESS ETHERNET HUB FOR PCMCIA ADAPTER
(LW005A)
The LW005A Hub, which is covered in detail in a separate user manual, is physically identical to the LW007A, but has different software. It works with portable computers equipped with the PCMCIA Wireless Adapter (LW006A) to connect to wired Ethernet LANs.
24
3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES
PCMCIA WIRELESS ADAPTER (LW006A)
The LW006A adapter, which is covered in detail in a separate user manual, gives the portable computer user complete mobility, allowing seamless roaming throughout the wireless LAN campus.
The PCMCIA Wireless Adapter converts any portable computer (notebook, laptop, pen-based, etc.) containing a PCMCIA Release 2.1 Type II slot into a wireless LAN station.
The LW006A adapter can communicate with any other wireless station in its coverage area, and can access all of the network resources like file servers, printers and shared databases via the Wireless Ethernet Hub (LW005A, covered in a separate manual).
The network stays connected while you roam between overlapping coverage areas; plus, you get continuous transmission and reception while moving at high speed without losing or duplicating data packets.

WIRELESS BRIDGE FOR PCMCIA ADAPTER (LW005A)
The Wireless Bridge for PCMCIA Adapter is covered in a separate user manual.
OPTIONAL ANTENNAS (LW011A AND LW012A)
The 6 dBi Omnidirectional Antenna (LW011A) and the Unidirectional Antenna (LW012A) work only with the LW005A and LW007A Hubs, LW008A and LW009A Adapters, and LW010A Bridge.

-Points of sale
27
3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES
•Workstation mobility—Notebook and pen-based computer users can roam throughout the Wireless Ethernet campus. As long as the coverage areas are overlapping this mobility is seamless. Users maintain their network connection while roaming from cell to cell.
•Quickly extends wired LAN—A Wireless Ethernet LAN cell gives instant add-on capability to your wired LAN for temporary or permanent expansion.
•Technical Advantages
-High data rate of 3 Mbps, with automatic fallback to 2 and 1 Mbps.
