RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy
and if not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication.
It has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart J of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference
when the equipment is operated in a commercial environment. Operation of
this equipment in a residential area is likely to cause interference, in which case
the user at his own expense will be required to take whatever measures may be
necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from

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.

15
3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES
4. Check the function of the Hub using
the front-panel LED indicators as follows:
• PWR—Power supply
• INFR—Radio interference
• ETH—Ethernet activity
• LOAD—Number of associated stations
(Low, Medium, High)

3. Introduction
3.1 The 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)
W IRELESS E
THERNET H UB (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.

17
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.
