Wireless LAN Adapter Product Reference Guide 1
Chapter 1 Introduction
The Intel®Wireless LAN PC Card is a direct-sequence
(DS) product. The Intel®PRO/Wireless 2011 LAN is a
spread spectrum network operating between 2.4 and
2.5 GHz. Spread spectrum communication provides a
high-capacity network within large or small
environments. Intel®PRO/Wireless 2011 LAN products
provide a high-capacity network using multiple access
points within large or small environments.
•Intel®PRO/Wireless 2011 LAN bridging
architecture allows communication between wired
network devices and mobile devices.
•Intel®PRO/Wireless 2011 LAN supports the IEEE
802.11 specification. This open architecture allows
devices to communicate with wireless devices from
other manufacturers.
•Intel®PRO/Wireless 2011 LAN allows mobile
devices to roam throughout large facilities while
remaining connected to the LAN.
•Intel®PRO/Wireless 2011 LAN allows protocol
firmware upgrades while devices remain
operational.
•Intel®PRO/Wireless 2011 LAN antenna diversity
feature alternates between antennas with the best
reception, increasing overall performance.

Chapter 2 About the Intel®
PRO/Wireless 2011
LAN Adapter
The Intel®PRO/Wireless 2011 LAN adapter allows PC
Card equipped host systems to configure, connect to
and establish a wireless network.
Features Include:
•Low-power operation for battery-powered devices
with PC Card slots
•Standard NDIS (Network Driver Interface
Specification)
•Windows 95, 98, NT 4.0 and 2000
driver support
•Card and Socket Services support
•Plug and Play support
•Power management [Continuously Aware Mode
(CAM) and Power Save Polling (PSP)].

2.1 MU Mode
In the Mobile Unit (MU) mode, the WLAN adapter
connects to an access point (AP) or another WLAN
installed system. MU mode allows the device to roam
freely between AP cells in the network. MUs appear as
network nodes to other devices.
2.2 11 Mbps Operation
The Intel®PRO/Wireless 2011 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.

2.3 Mobile IP
The Intel®PRO/Wireless 2011 LAN adapter supports
Mobile IP (roaming across routers) when properly
configured to support Mobile IP. The Mobile IP feature
allows 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
•move from one Ethernet segment to another.

2.4 Power Management
The WLAN adapter supports the Continuously
Aware (CAM) and Power Save Polling (PSP) power-
management modes. CAM requires the radio to remain
on. Intel does not recommend CAM for battery
powered devices.
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 Intel Network Control Panel Applet (NCPA) or
the Intel WLAN Monitor utility to manually set the PSP
performance index.
2.5 Card and Socket Services
The Intel®PRO/Wireless 2011 LAN 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.

Chapter 3 Hardware Installation
Physical installation of the PC Card differs for each
system. Refer to the system manufacturer
documentation for specific information.
3.1 Preparation
Before beginning the installation, verify the hardware
package contains:
•Intel®PRO/Wireless 2011 LAN adapter
•installation CD and utilities.
Verify the model indicated on the card and packaging
before use. Contact the Intel Support Center if an item is
missing or not functioning.

Hardware Installation
10 Wireless LAN Adapter Product Reference Guide
3.2 Installing the PC Card
The Intel®PRO/Wireless 2011 LAN PC Card
installation requires:
•a computer with a Type II PC Card slot
•a CDROM drive
•an available interrupt (IRQ)
•an available I/O port address
•Intel®PRO/Wireless 2011 LAN driver installation
CDROM.
Installation and removal methods vary for different host
devices. Refer to system documentation for information.
Avoid WLAN adapter contact with liquids or
abrasive materials.
To install the PC Card:
1. Insert the PC Card into the PC slot. Arrows on the
front of the PC Card indicate the insertion point to
the slot.
