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

digital apparatus set out in the Radio Interference Regulation of Industry Canada.

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

(LW001A, LW005A,

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.
