RF Devices
Symbol’s RF products are designed to be compliant with the rules and regulations in the locations into which they are sold and
will be labeled as required. The majority of Symbol’s RF devices are type approved and do not require the user to obtain license
or authorization before using the equipment. Any changes or modifications to Symbol Technologies equipment not expressly
approved by Symbol Technologies could void the user’s authority to operate the equipment.
Telephone Devices (Modems) - United States
If this product contains an internal modem it is compliant with Part 68 of the Federal Communications Commission Rules and
Regulations and there will be a label on the product showing the FCC ID Number and the REN, Ringer Equivalence Number.
The REN is used to determine the quantity of devices which maybe connected to the telephone line. Excessive RENs on the
telephone line may result in the device not ringing in response to an incoming call. In most but not all areas, the sum of the
RENs should not exceed 5.0. To be certain of the number of devices that may be connected to the line, as determined by the
total number of RENs, contact the telephone company to determine the maximum REN for the calling area.
If the modem causes harm to the telephone network, the telephone company will notify you in advance; however, if advance
notice is not practical, you will be notified as soon as possible. Also, you will be advised of your right to file a complaint with the
FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations or procedures that could affect the operation
of the modem. If this happens the telephone company will provide advance notice so you may make any necessary
modifications to maintain uninterrupted service.
Telephone Devices (Modems) - Canada
If this product contains an internal modem it is compliant with CS-03 of Industry Canada and there will be a Canadian
certification number (CANADA: ____) on a label on the outside of the product. This certification means that the equipment
meets certain telecommunications network protective, operational and safety requirements. The Department does not
guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed using an acceptable method of connection. In some
cases, the company’s inside wiring associated with a single-line, individual service maybe extended by means of a certified
convector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may
not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
User should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and
internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in
rural areas.
CAUTION: User should not attempt to make such connections themselves, but should contact the appropriate electric inspection
authority, or electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to the
telephone loop which is used by the device, to prevent overloading. The termination of a loop may consist of any combination
of devices, subject only to the requirement that the total of the Load Numbers of all devices not exceed 100.

Introduction
Spectrum24 is a frequency-hopping, spread spectrum
network that operates between 2.4 and 2.5 GHz.
Spectrum24 operates similarly to Ethernet networks without
a wired network infrastructure. Spread spectrum
communication provides a high-capacity network within
large or small environments. Interference reduction makes
it ideal for mobile communications and real-time data
access applications.
•
Spectrum24 bridging architecture allows
communication between wired network devices and
mobile devices.
•
Spectrum24 switchable data rates allow 1 Mbps
and 2 Mbps devices to communicate in the same
network environment.
•
Spectrum24 supports the IEEE 802.11 specification.
This open architecture allows Spectrum 24
devices to communicate with wireless devices from
other manufacturers.
•
Spectrum24 allows mobile devices to roam
throughout large facilities while remaining connected
to the LAN.
•
Spectrum24 allows protocol firmware upgrades while
devices remain operational.
•
Spectrum24 antenna diversity feature alternates
between antennas with the best reception, increasing
overall performance.

Spectrum24 Wireless LAN Adapter Product Reference Guide
Chapter 2
Wireless LAN Adapter
The Spectrum24 Wireless LAN (WLAN) adapter allows ISA
(Industry Standard Architecture) or PC Card equipped host
systems to configure, connect to and establish a
Spectrum24 network. The ISA adapter version of the
WLAN implements the Plug and Play standard. When
installed in a system with a Plug and Play BIOS (basic input
output system), the card requests system resources. The
system allocates an Interrupt Request (IRQ), Input-Output
(I/O) port and memory address range. Host systems
without Plug and Play BIOS acquire Plug and Play
functionality through the CSS (Card and Socket services)
utilities that normally come bundled with system software.
Features Include:
•
Low power operation for battery-powered devices with
PC Card slots.
•
Standard NDIS (Network Driver Interface
Specification) and ODI (Open Data-link
Interface) drivers.
•
Windows 95, NT 4.0/3.51 driver support.
•
Card and Socket Services support.
•
Plug and Play support.
•
Antenna options (molded external antenna available
for PC Card only).
•
Power management (Continuously Aware Mode or
Power Save Polling mode)
Spectrum24 Wireless LAN Adapter Product Reference Guide
Wireless LAN Adapter
2.1 MU Mode Operation
In the Mobile Unit (MU) mode, the WLAN adapter
connects to an Access Point (AP) or another WLAN
installed system operating in MicroAP mode. The MU
mode allows the device to roam freely between AP
cells in the network. MUs appear as network nodes to
other devices.
Spectrum24 Wireless LAN Adapter Product Reference Guide
Wireless LAN Adapter
2.2 MicroAP Mode Operation
In the MicroAP mode, the WLAN adapter performs as an
Access Point. The Spectrum24 WLAN adapter installed in a
PC without another network connection, establishes a
single-cell wireless network coverage area for all 802.11
devices in MU mode. Each MicroAP needs to have a
unique ESS_ID. Cells can coexist as separate, individual
networks at the same site without interference. The
MicroAP does not roam, but it does support roaming. It
has to operate in continuous aware mode in order to
support CAM and PSP MUs. MUs can operate only within
the cell established by WLAN adapter in this mode. The
MicroAP mode supports up to 16 MUs. An Access Control
List (ACL) containing the MU MAC addresses within the
Spectrum24 Wireless LAN Adapter Product Reference Guide
Wireless LAN Adapter
established cell allows only the specified MUs (within the
ACL) to associate with a MicroAP. Set the MicroAP and the
MU to the appropriate data rates to communicate. Refer to
the MicroAP Rate Control Table for the rates. The table
below shows the compatible data rates. The adapter is
configured to operate in the MicroAP mode through the
Spectrum24 Network configuration dialog screen for

2.4 Mobile IP (roaming across routers) Description
The Spectrum24 WLAN supports Mobile IP (roaming
across routers) when properly configured as an MU and
configured to support Mobile IP (refer to appendix G
for configuration and setup). Also configure an Access
Point to properly pass through routing information. The
MU retains its IP address when configured for Mobile IP
and can:
•
move from one IP subnet to another
•
move from an Ethernet segment to a wireless LAN
•
move from one Ethernet segment to another.
2.5 Power Management
The WLAN adapter provides two power-management
operation modes: Continuously Aware Mode (CAM)
requires the radio to remain on. Symbol does not
recommend CAM for battery powered devices.
A WLAN adapter operating in MicroAP mode functions in
CAM only. The ISA adapter functions in CAM only.
Spectrum24 Wireless LAN Adapter Product Reference Guide
Wireless LAN Adapter
Power Save Polling (PSP) mode allows the MU to conserve
power by suspending communication while still associated
with an AP. The AP saves data for the MU, which wakes at
given intervals to check for data. The WLAN adapter
drivers support dynamic power management, Algorithm
11 and 12 (refer to Appendix A for usage). Algorithm 11
varies the PSP parameter between 1 and 10 depending on
data traffic. Algorithm 12 switches the LAN adapter from
PSP mode to CAM, also depending on data traffic.
2.6 Card and Socket Services
The Spectrum24 WLAN adapter supports Card and Socket
services. In a DOS environment the WLAN adapter can
use Spectrum24 automatic configuration, hot insertion,
removal and power management features. Card and
Socket Service software packages providing these
features include SystemSoft, CardSoft or CardWizard
(not included).
The WLAN adapter supports Card and Socket Services
native to Microsoft Windows 95 but not in Windows NT.
2.7 Plug and Play
The Spectrum24 WLAN card Model 3020(PC Card) and
Model 3025 (ISA adapter) support Plug and Play systems.
This allows the PC to automatically recognize the WLAN
adapter, and configure the hardware interrupt, memory
and I/O addresses. This feature requires less user
interaction and minimizes hardware conflicts.
