Introduction

The e-mobility 802.11b Wireless LAN DSSS Access Point (AP)
provides a bridge between Ethernet wired LANs and e-mobility
wireless networks. It provides transparent access between
Ethernet wired networks and radio-equipped mobile units (MUs).
MUs include all of Nortel Networks
scanners, third- party devices, and other equi pment.

The access point provides an 11 Mbps data t r ansfer rate on the
radio network. For further information about access point
configuratio n, refer to Reference for the e-mobility 802.11b
Wireless LAN DSSS Access Point (part number 210669-x).

Precautions

Before installing the access point (AP) verify the following:

• The location for the unit is dry and dust free. Install in wet or
dusty areas only with additional protection. Contact a Nortel
Networks representative for more information.

• The environment has a temperature range between -20° C
and 55° C.

Requirements

The minimum installation requirements for a single-cell, peer-to­peer network are a power outlet and an antenna.

Note: Use and test the radio network with a pr operly

equipped e-mobility mobile unit.

™ e-mobility™ terminals,

Network Connection

Locate connectors for Ethernet, antennas, and power on the back
of the AP. Ethernet config ura tio ns vary according to the
environment.

Note: The e-mobility site survey utility can be used to

determine the number of access points to install and their
locations.

10BASE-T UTP

Use a 10BASE-T connection for multiple access points or an
access point attached to a wired UTP Ethernet hub or switch.
Normal 10BASE-T limita tions ap ply.

To establish a 10BASE-T connection:

1 Plug the data cable RJ-45 connector i nt o the access point

RJ-45 conne ctor.

2 Plug the other end of the data cable into the LAN access port,

possibly a hub or wall connection.

3 Add additional access points as needed.

Note: When connecting the e-mobility access point to an

Ethernet switch, ensure the switch port parameters are set
to 10 Mbps Half Duplex. Severe performance
degradation may result from mis-matched speed or
duplex modes.

8

Mounting the AP

The AP rests on a flat surface or attaches to any hard, flat, stable
surface. Position the AP at any angle. Use the standard-mounting
kit provided.

Choose an option based on environment:

• Resting flat
The AP rests on the four rubber pads on its underside. Place
the AP on a surface clear of debris and away from traffic.

• Attaching on the wall in any direction
The AP attaches to a wal l and ca n be orie nted in any positio n
as long as the antennas are oriented vertical ly.

e-mobility 802.11b Wireless LAN DSSS Access Point Antennas

Antenna coverage is analogous to lighting. Users might find an
area lit from far aw ay t o be no t brigh t enou gh. An area lit sharpl y
might minimize coverage and create dark areas. Uniform antenna
placement in an area (like an even placement of light bulbs)
provides even, efficient coverage.

Place the antenna using the foll owing gui del ines:

• Install the antenna as high as practical.

• Orient the antenna vertically for best reception.

• Point the antenna downward if attaching the AP to the
ceiling.

The AP requires one antenna and can use two. Two antennas
provide diversity that can improve signal reception.

Attach antennas to ANTENNA connectors on the back of the AP.
For a single antenna, use the PRIMARY ANTENNA connector
and set the Antenna Di v ersit y setting to Pr imary On ly. This is the
left antenna connector when viewed from the front of the unit. It
is identified by one vertical bar on the bottom of the unit. The
secondary antenna is marked with two vertical bars.

10

The standard antenna performs well in most office environments.
Obtain additional or higher-performance antennas from Nortel
Networks. Contact a Nortel Networks representa tive to order the
following models:

• Standard rubber antenna

• Single high-performance antenna

• Twin high-performance diversity antennas

• Mountable F-plan e antenna

If installing two antennas, enab le the Antenna Di ve rsity option in
the User Interface. Refer to Access Point Installation in the

Reference for the e-mobility 802.11b Wireless LAN DSSS Access
Point (part number 210669-x).

Antenna Extension Cables

Nortel Networks offers extension cables for access point
antennas. Some range loss oc curs when increasing the distance
between the antenna and the access point.

Length Loss Range Loss

6 ft 2.0 dB 5%
12 ft 4.0 dB 10%

To order extension cables, contact a Nortel Networks
representative.

11

Connecting the Power Adapter

The power adapter connects to the rear of the access point and to
a power outlet.

To connect the power adapter:

1 Verify that the power adapter matches the country-of-use

requirements.

2 Plug power adapter cable into the socket on the back of the

access point.

3 Plug the adapter into an outlet .

When the Power indicator on the front of the access point stops
flashing and lights solid green and the Wirele ss LAN Activity
indicator begins flickering, the access point is functional and
ready to associate with MUs.

Note: The e-mobility access point may also be powered

by using the Remote Power Interface (RPI) in
conjunction with the AC Power Adapter. The RPI
enables the access point to be installed in locations
without direct access to AC power. Refer to 210672A,
“Installing the e-mobility 802.11b Wireless LAN DSSS
Remote Power Inteface” for details.
