About the Spectrum24 Wireless LAN Adapter
2.2 11 Mbps Operation
The Spectrum24 Wireless LAN adapter supports an
11 Mbps data rate. The adapter can default to a 5.5,
2 or 1 Mbps data rate when unable to establish an
11 Mbps association.
The following factors can dynamically alter the
data rate:
• signal strength between the AP and the MU
• the ratio of good transmitted packets to attempted
• transmitted packets fall below a threshold
• the MU finds a higher transmit rate with another AP
or it encounters an unspecified data rate.

configured to support Mobile IP. The Mobile IP feature
allows Spectrum24 Wireless LAN devices to roam
across routers.
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

2.4 Power Management
The WLAN adapter supports the Continuously
Aware (CAM) and Power Save Polling (PSP) powermanagement modes. CAM requires the radio to remain
on. Symbol does not recommend CAM for battery
powered devices.
The PCI version of the Spectrum24 WLAN adapter
functions in CAM only.
PSP mode allows the MU to conserve power by
suspending communication while still associated with
an AP. The AP saves data for transmission to the MU
when it wakes at given intervals. When the adapter
wakes to check for data, it switches back into CAM
until it is ready suspend communications again.
The PSP performance index, which varies from 1 to 5,
allows users to specify how often the MU wakes up to
check for data. PSP performance index 1 provides the
quickest response time (shortest sleep interval), while
PSP performance index 5 provides efficient power
consumption (longest sleep interval).
Use the Symbol Network Control Panel Applet (NCPA)
or the Symbol Network Interface Card Task Tray (NICTT)
utility to manually set the PSP performance index.

2.5 Card and Socket Services
The Spectrum24 WLAN adapter supports Card and
Socket services. Card and Socket Service software
packages work with the host computer operating system
enabling the Wireless LAN adapter to interface with
host computer configuration and power management
functions. Card and Socket Service software packages
include SystemSoft and Phoenix.
2.6 Plug and Play
The PCI version of the Spectrum24 WLAN adapter
supports Plug and Play systems. This allows a computer
to recognize the PCI adapter, and configure the
hardware interrupt, memory and device recognition
addresses. This feature requires less user interaction
and minimizes hardware conflicts.

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
acilities, 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.
