Chapter 1 Introduction
Overview
Now you can access enterprise and public Wi-Fi (IEEE
802.11b) Wireless LAN systems from your Pocket PC
using the smallest and lightest form factor available with
Socket’s SDIO Low Power Wireless LAN Card. All you
need is a Pocket PC 2002/2003 with a SDIO slot running
SDIO Now!, and you can use the card to access the
Internet, email, and corporate servers.
The Socket SDIO Low Power Wireless LAN Card uses Direct Sequence
Spread Spectrum (DSSS) technology operating at 2.4 –2.5 GHz. Data rates
up to 11 Mbps are supported, providing the speed needed for quick data
downloading. The card works in environments that are open or have 40/64-
bit or 128-bit encryption enabled. For Pocket PC 2003, the card also
supports 802.1x authentication using either Extensible Authentication
Protocol-Transport Level Security (EAP-TLS) or Protected Extensible
Authentication Protocol (PEAP) for environments with enhanced security.
The Low Power Wireless LAN Card can be used in two operating modes.
In Infrastructure mode (default), the adapter transmits and receives data
with an associated access point (AP) or an infrastructure of networked APs.
Ad Hoc mode lets you create one-to-one or one-to-many peer-to-peer
networks without APs, connecting directly with other 802.11b cards.
For a complete list of Pocket PCs compatible with the card, please visit:

Corporation and the SDIO form factor, please visit:

Note: The MAC address of the card is on a label on the back of the card.

Chapter 3 Open or WEP-Enabled
Networks for Pocket PC 2003
This chapter explains how to use the Low Power SDIO WLAN Card to
connect to an open or WEP-enabled network. Before you try to connect, be
sure to install Socket’s software and insert the card, as described in Chapter
2, “General Installation.”
STEP 1: Prepare Network Information
Find out what security settings you need to connect to your open or
WEP-enabled WLAN network. If applicable, consult with the network
administrator. The necessary settings may include the following (only
some will apply):
• Wireless network name, known as ESSID or SSID
• Encryption type, WEP key(s), WEP key format (hex or ASCII)
• Use of either DHCP or Static IP to assign IP addresses
For a Network Information Form that you can email to your network
administrator, go to:
• Appendix C of this User’s Guide
• The Docs folder on the installation CD
• ftp://ftp.socketcom.com/wlan/WLAN_NetworkForm.txt

STEP 2: Connect to WLAN
The Zero Configuration utility for Windows Mobile 2003 makes it quick and
easy to connect to WLAN networks. For more details on the utility, refer to
the Pocket PC 2003 manual. For help, tap Start | Help.
Whenever you insert the card, it will automatically start searching for: (1)
any WLANs advertising their ESSIDs; and (2) any WLANs you have saved
settings for. If your network administrator chose to not make the ESSID
visible, you need to first enter and save network settings, then try to connect.
SCENARIO 1: The WLAN makes the ESSID visible.
1. A few seconds after you insert the WLAN card, the Socket status
icon will appear in the menu bar. Do not tap on the icon.
2. A few seconds to a minute later, a
bubble should appear reporting detected
WLANs. Select your WLAN and what
it will connect to. Tap Connect.
Note: In most cases, you should choose
The Internet. If your network uses a
VPN/proxy server, refer to the PPC
2003 manual for instructions.
The bubble will not appear if you have
enabled the “Automatically connect to
non-preferred networks” setting, or if a connection already exists.
3. A bubble will appear that will allow you to enter a WEP key if required.
4. When you have connected, the “x” will disappear from the
connection icon at the top of the screen.

Chapter 4 802.1x Networks for
Pocket PC 2003
This chapter explains how to use the Low Power SDIO WLAN Card with a
Pocket PC 2003 to connect to an 802.1x network. Before you try to
connect, be sure to install Socket’s software and insert the card, as
described in Chapter 2, “General Installation.”
STEP 1: Prepare Network Information
Verify Card and Network Compatibility
Socket’s card cannot connect to an 802.1x network unless the network satisfies
the four requirements below. Consult with your network administrator.
 Windows Internet Information Service (IIS)
 Windows Internet Authentication Service (IAS)
 Windows Certification Authority (CA) with automatic approval and correct
Pocket PC certificate format (via MS certificate template)
 Access point configured only for 802.1x (i.e., no multi-mode support or static
128-bit WEP keys)
Prepare Security Settings
If the network is compatible, ask the administrator for necessary security settings:
 Wireless network name, known as ESSID or SSID (case sensitive)
 Authentication type, user name, password
 Use of either DHCP or Static IP to assign IP addresses
 Authentication permission restrictions (e.g., domain administrators only)
For a Network Information Form that you can send to your network
administrator, go to any of the following:
• Appendix C of this User’s Guide
• Docs folder on the CD
• Visit: ftp://ftp.socketcom.com/wlan/WLAN_NetworkForm.txt
Note: If your network only allows domain administrators to authenticate, ask
your network administrator to assign you this privilege.
Obtain 802.1x Certificate(s)
 Ask the administrator for a copy of the root certificate from a Trusted Root
Authority (no intermediary authority). Installation instructions are in Step 3.
EAP-TLS only: You also need to set up a cabled connection to the network to
install a personal certificate. Installation instructions are in Step 3.

802.1X NETWORKS FOR PPC 2003 | 15
STEP 2: Install 802.1x Certificates
1. If you have not done so already, get a root (server) certificate from your
network administrator. The root certificate must come from a Trusted
Root Authority (not an intermediary authority).
2. If the SDIO WLAN Card is inserted, remove the card.
3. Make an active connection between your Pocket PC and host PC. Use
ActiveSync and a serial/USB/Ethernet cable or cradle.
4. Use My Computer or Windows Explorer to access your Mobile Device and
copy the root certificate into the Business folder of the Pocket PC.
5. On your Pocket PC, use File Explorer to navigate to the Business folder.
Tap on the certificate.
6. A message will ask if you want to install the certificate. Tap Yes.
• If your network uses PEAP, disconnect your Pocket PC from the host
PC. Soft reset the Pocket PC by pressing the reset button. Now you are
ready to proceed to Step 4 to insert the card.
• If your network uses EAP-TLS authentication, you also need to install a
personal (client) certificate.

16 | CHAPTER 4
7. To install a personal certificate, tap: Start | Programs | Cert Enroll.
8. Enter the User, Password, and Server information as supplied by your
network administrator. Tap Retrieve.
Note:
• In the User field, enter your domain and user name in the format
shown, using a backslash (“\”) between the domain and user name.
• In the Server field, enter either the name or the IP address (using
standard dot notation) of the server running Certificate Services on
your network.
9. After your Pocket PC retrieves a personal certificate, tap ok.
10.Disconnect the Pocket PC from the host PC.
