Introduction
Terminology
When configuring your system, and when reading this
manual, keep in mind the following terminology:
Infrastructure – The wireless infrastructure is the
communications system that combines Aironet Access
Points, mobile stations and fixed stations. Aironet Access
Points within the infrastructure can be either root units,
which are physically wired to the LAN backbone, or can act
as wireless repeaters. Other RF enabled devices serve as
fixed stations or mobile stations.
Cell – A single Aironet Access Point transmits and receives
data within an area called a cell. A cell is the area of radio
range (coverage) in which the Access Point can
communicate to other devices in the wireless infrastructure.
The size of a single cell depends upon the speed of the
transmission, the type of antennas used, the physical
environment as well as other factors. The size of the entire
coverage area for the wireless infrastructure can be
increased by adding Access Points, thus adding cells.
Root Unit – The root unit is an Aironet Access Point that is
located at the top, or starting point, of a wireless
infrastructure. The root unit provides the physical connection
to the wired LAN (such as Ethernet) and contains
configuration information in its association table that covers
all stations in the infrastructure.
Repeater – A repeater is an Aironet Access Point that
extends the radio range of the infrastructure. A repeater is
not physically attached to the wired LAN, but communicates
via radio to another Access Point, which is either a root unit
or another repeater.
1-5
Introduction
Radio Node – A PC, file server, notebook computer, etc.
containing a Radio Card or LAN Adapter.
End Node – A radio node that is located at the end of the
Network Tree.
Parent/Child Node – Refers to the relationships between
nodes in the wireless infrastructure. The complete set of
relationships is sometimes described as a Network Tree.
For example, the Aironet Access Point (at the top of the
tree) would be the parent of the end nodes. Conversely, the
end nodes would be the children of the Aironet Access
Point.
Association – Each root unit or repeater in the
infrastructure contains an association table that controls the
routing of packets between the LAN backbone and the
wireless infrastructure. The association table maintains
entries for all the stations situated below the Aironet Access
Point on the infrastructure including repeaters and radio
nodes.
Power Saving Protocol (PSP) and Non-Power Saving
Protocol – The Power Saving Protocol allows computers
(usually portable computers) to power up only part of the
time to conserve energy. If a radio node is using the Power
Saving Protocol to communicate with the network, the
Aironet Access Point must be aware of this mode and
implement additional features such as message store and
forward.
1-6
Introduction
Understanding the Infrastructure
The infrastructure is designed like an upside-down tree with
a root unit at the top and repeaters, stations, and mobile
stations branching down from the root unit as shown below.
The AP3500-E Aironet Access Point can serve as a root
unit, providing wireless data communications between the
Ethernet based networks and other stations/mobile stations
or within the wireless infrastructure.
Wired LAN
Root Unit
Portable Laptop

Introduction
In the example, the Access Point maintains an area of RF
coverage (cell). Any radio node within the cell’s area can
communicate to any other node (via radio or across the
wired Ethernet LAN) using the Access Point.
If a larger area of RF coverage is required, additional
Access Points can be added either as root units, attached to
the LAN, or as repeaters. Each Access Point adds its own
cell, which can be used to provide additional coverage area,
greater total bandwidth, or network redundancy.
For information about how to configure the AP3500-E as a
repeater or other networking and system configuration
issues, see the AP3500-E Technical Reference Manual
document #710-004021.
Information about optional long range antennas is available
from the Aironet Antenna Guide document #710-003725 or
your Aironet supplier.

Configuration
Configuration
This section describes the methods used to access and
configure the Console system of the Aironet Access Point.
This system contains all commands necessary to initially
configure and monitor the operation of the unit.
Accessing the Console System
There are many ways in which you may configure and
monitor the Aironet Access Point. When the unit is first
powered up, basic configuration must initially be performed
by accessing the Console serial port.
To gain access through the serial port, the Aironet Access
Point must be connected to a terminal or a PC running a
terminal emulation program. Set the terminal to 9600 Baud,
No-Parity, 8 data bits, 1 stop bit, and ANSI compatible.
The Console system is organized as a set of menus. Each
selection in a menu list may either take you to a sub-menu
or display a command that will configure or display
information controlling the unit.
Once the Aironet Access Point has been assigned an IP
address, you may then access the Console remotely using:
•
•
•
Telnet protocol from a remote host or PC
HTML browser, such as Netscape Navigator from a
remote host
Simple Network Management Protocol (SNMP) from a
remote network management station
3-1
Configuration
Configuring the Access Point
To configure the Aironet Access Point so it will communicate
with other stations or repeaters, use the Console Port to set
the SSID parameter.
If you choose to set an IP address, remote access via telnet
or an HTML browser will be possible.
SSID Identifier (ESSID)
The SSID is a unique identifier that is attached to
selected packets sent out over the radio network. This
functions as a password to join the radio network.
Stations associating to the Aironet Access Point must
use the same identifier in their configurations, or their
association requests will be ignored.
To define an SSID:
1. Select Configuration from the Main Menu.
2. Select Radio from the Configuration Menu.
3. Select ESSID.
4. Enter a value for the SSID option. You may use up
to 32 characters. All devices in the same radio
network must use the same SSID.
3-2
Configuration
Assigning an IP Address
An IP address must be assigned to the unit before it can
be accessed by telnet, HTTP, or SNMP. Other detailed
internet addressing options (such as gateway address,
SNMP routing, etc.) can also be defined. Refer to the
Technical Reference Manual document #710-004021
for further details.
To assign an IP address:
1. Select Configuration from the Main Menu.
2. Select Ident from the Configuration Menu.
3. Use the INADDR option to establish an IP address.
4. Use the INMASK option to define the internet mask,
as appropriate.
Verifying Association
