access your 2102 S from a remote location.

Although you can manage the device remotely using either a Telnet session or a

Note:

Web browser, this manual assumes you are using a Web browser.

You must know the IP address of the access point to access it remotely. If a DHCP
server assigned the IP address, you must determine the IP address from the DHCP
server.

Only one session can be active with the access point at a time. If your session terminates
abruptly or a new signon screen appears, someone else may have accessed the access
point.

To access the access point remotely, you must first establish a Web browser session.
When using the Web to establish remote access to your access point, remember that if
you have a username and password configured for the access point, your session
terminates if you do not use it for 15 minutes.

Configuring the 2102 S Access Point as a DHCP Server

The 2102 S access point contains a simple DHCP server that you can use to provide
DHCP server functions for small installations where no other DHCP server is available.
The DHCP server will offer IP addresses to any DHCP client it hears as long as a pool
of unallocated IP addresses is available. These clients may include other access points,
wireless clients, wired hosts on the distribution LAN, or wired hosts on secondary
LANs.

This DHCP server is not intended to replace a general purpose, configurable

Note:

DHCP Server Parameters

Parameter Explanation

Low Address Specifies the low IP address in the range of IP addresses available to the DHCP server for

distribution to DHCP clients. If these addresses are not on the same subnet as the access point, the
access point will perform Network Address Translation (NAT) for the devices to which it grants
IP addresses.

High Address Specifies the high IP address in the range of IP addresses available to the DHCP server for

distribution to DHCP clients. If these addresses are not on the same subnet as the access point, the
access point will perform Network Address Translation (NAT) for the devices to which it grants
IP addresses.

DNS Address 1 Specifies the IP address of a Domain Name Server that will be distributed to DHCP clients. You

can enter up to two DNS addresses to be delivered to DHCP clients.

DNS Address 2 Specifies the IP address of a Domain Name Server that will be distributed to DHCP clients. You

can enter up to two DNS addresses to be delivered to DHCP clients.

IP Subnet Mask Indicates how many host bits of the IP address represent a subnet number. Use IP subnets to

partition traffic and to connect routers. The IP subnet mask must represent contiguous ones (1)
from the left and contiguous zeros (0) from the right.

IP Router (Gateway) Specifies what IP router DHCP will be offering to clients. If NAT has been automatically enabled,

the access point will use the lowest DHCP address to provide an IP router that performs NAT.

NAT (Network
Address Translation)
Status

Specifies if DHCP has been properly configured and if the range has automatically enabled NAT.
NAT operation is disabled or enabled automatically depending on the continuous range of

addresses you enter into the DHCP Server. NAT is disabled if the ra nge of addresses to be given
to DHCP clients is on the same subnet as the access point. If the range of addresses to be given
out by the DHCP server is not on the same subnet as the access point, you are creating a virtual
network and the DHCP server will also perform NAT translation.

Supported DHCP Options

The DHCP server issues IP address leases to configure the following fields and options:

IP broadcast address

contain the same values as configured for the access point.

Lease duration

This address, along with the subnet mask and default router, will

The default lease duration is twenty minutes.

Unsupported DHCP Options

The DHCP server implemented in the 2102 S access point does not support any DHCP
options other than those listed on this page. The DHCP server disregards any DHCP
options that are not explicitly required by the DHCP specification. The DHCP server
ignores all packets with a non-zero giaddr (gateway IP address). The DHCP server only
responds to requests emanating from it’s own subnet.

to transmit and receive packets. The available frequencies are country-dependent and are
determined by the radio.

Configure all access points used in Spain, France, or Japan to a common frequency. For all other
countries, you can configure all access points to a common frequency, or you can select up to three
frequencies that are at least three channels (or 25 MHz) apart. You could select 2412 MHz, 2437
MHz, and 2462 MHz, for example.

You may want to use a single frequency to isolate the installation to part of the band; for example,
use a single frequency if other DS systems or multiple microwave ovens are in use in the area.

For optimal performance of access points that are within range of each other, you should configure
their frequencies to be five channels apart. You could configure the access points to use channels 1,
6, and 11, for example.

WEP Encryption Use this option to enable or disable WEP encryption. This option appears on your menu only if

your 802.11b HR radio supports WEP data encryption for wireless communication.

Using External Antennas

asdf

This appendix provides information about attaching and positioning external antennas
with the 2102 S. Specific guidelines for antenna separation are provided for those
configurations that have multiple antennas.

Attaching an External Antenna

You can attach an external antenna to the 2102 S. To attach an external antenna, you
must disconnect the built-in antenna and attach an antenna cable directly to the radio
card in the access point. The following steps explain how to attach an antenna cable to
the 2102 S.

For more information about antenna options, contact your local Intermec representative.

To attach an external antenna to the 2102 S

1. Remove the radio card door.

2. Pull straight up on the antenna wire to disconnect it from the radio card.

5. Attach the antenna cable to the radio by inserting the cable connector into the radio
card.

6. Replace the door.

General Antenna Placement Guidelines

Proper antenna placement can help improve range. For information about antenna
options, contact your Intermec representative. Here are some general guidelines for
positioning antennas:

Place the antenna as high as possible. In an office environment, try to place it above

•

cubicle walls.
Do not place a sheet of metal (such as a filing cabinet) between two antennas.

•

The following sections provide detailed information about antenna placement for those
access points that can have more than one antenna.

Positioning Antennas for IEEE 802.11b HR Radios

The 802.11b HR radio features antenna diversity, which means that two antennas can be
attached to a single radio. The antenna ports on the radio card are marked | and ||. Port |
is the send/receive port; port || is the receive-only port. (Note that the antenna diversity
system uses only one antenna at a time.)

Intermec recommends that you use two antennas for optimal performance of your

802.11b HR radio. If you attach only one antenna to the 802.11b HR radio, you must

attach it to Port |. Both antenna ports are visible on the 2102 S.

Positioning Antennas for Antenna Diversity

If you are using two antennas for one 802.11b HR radio, placement of the antennas is
critical because each antenna has a particular function. Antennas placed too close
together may cause interference with each other. Antennas placed too far apart may not
be able to establish two-way communications with other radios. To achieve optimum
placement for the two antennas, you must place the transmit/receive antenna so that it is
within range of all the radios that the receive-only radio can hear.

Note these important points about antenna placement for an 802.11b HR radio:

Use external antennas to achieve the recommended antenna separation for

•

placement of either omni or directional antennas.
Position directional antennas so they point in the same direction.

•

B-4

Using External Antennas

Follow the recommended antenna separation precisely when using the closest

•

distances. Movement of as little as 3.05 centimeters (1.2 inches) may strongly affect
performance.

Position the antennas so that both antennas are within range of the radios they need

•

to communicate with.
Do not position the two antennas around a corner or so that a wall is between them.

•

The recommended antenna separation is listed in the following table. You should
choose the greatest distance possible within the constraints of your environment.

Location Recommended Antenna Separation

Highly reflective warehouse environment 0.33 m (13 in) or 0.64 m (25 in)
Moderately reflective warehouse environment 0.64 m (25 in), 1.22 m (4 ft), or 1.83 m (6 ft)
Open/Office environment 1.22 m (4 ft) to 3.05 m (10 ft)
