Overview
This document is designed to assist users in understanding wireless communication, how it works, and
how to create and configure wireless Local Area Network (WLAN) connections on HP iPAQ Pocket
PC h4100/4300 series and h5400/h5500 series handheld devices.
HP iPAQ Pocket PC wireless products
HP currently offers the HP iPAQ Pocket PC h4100 series, h4300 series, h5400 series, and the h5500
series. These Pocket PCs have integrated WLAN capability.
What is a WLAN?
A wireless network is a group of computers and associated devices that share a common wireless
communication link over radio waves. A wireless network is enabled by a collection of wireless
access points residing within a small geographic area, such as in an office building or wide fidelity
(Wi-Fi) public hotspot.
WLANs enable a variety of mobile transactions such as Internet and e-mail access, and sophisticated
tasks such as allowing sales people to access customer records from customer locations. The signal
strength of a WLAN can normally reach a maximum radius of 500 feet indoors and 1,000 feet
outdoors, however the area can be extended with antennas, transmitters and other access devices.
Figure 1.0 below illustrates a WLAN setup with an access point.
NOTE: Signal strength may be reduced by conditions such as wireless interference, obstructions
(walls, for instance), and signal reflection. The radius listed above represents the maximum distance
an un-enhanced WLAN signal can travel under prime operating conditions.
Figure 1.0 WLAN with access point
Wireless fidelity
Wi-Fi, also known as 802.11 is a communication standard created by the Institute of Electrical and
Electronic Engineers (IEEE). 802.11 defines the electrical and radio frequency components of a
The Wireless LAN and HP iPAQ Pocket PCs 5

wireless Ethernet. The standard also defines an encryption algorithm (Wired Equivalent Privacy –
WEP) to secure the network. The Wi-Fi Alliance is the body that ensures compatibility and is
responsible for issuing standard compliance tests and logos.
Wi-Fi hotspots
Wi-Fi hotspots are WLANs that use the IEEE 802.11 protocol to establish wireless connections for
general public use. Offered to customers by a growing number of hotels, restaurants, airport lounges,
coffee shops and other businesses, Wi-Fi hotspots enable users to access Internet resources, send and
receive e-mail, use instant messaging, and perform similar tasks they would otherwise perform on their
business or home PCs. Many Wi-Fi hotspots charge their customers a fee for this service.
Convenience and increased productivity make Wi-Fi hotspots attractive to users on the go, but
hotspots may also increase the possibility of security risks. The security risks are manageable,
however, if safety precautions are taken. For information about measures users can take to minimize
security risks in WLAN connections, refer to the HP white paper entitled secure wireless local area
networks with hp mobile devices located at the following website:
http://www.hp.com/sbso/wireless/secure_wlan_mobile.pdf
What’s the difference between wireless and mobile?
A mobile device is a portable device. A desktop could be a mobile device if it could be easily carried
around. A wireless device, such as the HP iPAQ Pocket PC h4100, h4300, h5400, or h5500 series
handheld device, provides some type of network connectivity. A cell phone is wireless; a laptop or
PDA can be wireless when using a wireless modem. Similarly, applications are wireless when they
connect and exchange data with a network.
Common WLAN terms
Access Points
Access Points connect wireless networks and enable the sending and receiving of data between
wireless clients. It is the connection point for a network, most often a component that is hard-wired
into the main network. Access points are responsible for converting the wired network into a wireless
one. An access point serves as a communication hub, a traffic controller, directing all the data on the
network and allowing a user to communicate at maximum speed.
Wireless networks allow users to "roam" between access points, working in much the same way as
cellular phones. More detailed information about roaming appears later in this document.
Virtual Private Network
A virtual private network (VPN) allows two or more private networks to be connected over a publicly-
accessed network. In a sense, VPNs are similar to WANs or a securely encrypted tunnel, but the key
feature of VPNs is that they can use public networks like the Internet, rather than rely on expensive,
privately leased lines. Additionally, VPNs have the same security and encryption features as private
networks.
Voice over IP
Voice over Internet Protocol (VoIP) is the ability to make telephone calls and send faxes over IP-based
data networks with a suitable quality of service and superior cost/benefit ratio.
The Wireless LAN and HP iPAQ Pocket PCs 6

Terminal services client
The Terminal Services Client establishes a session with the server. User keyboard and mouse activity
is sent via the network to control the server session. Applications launched in the session use the
resources (processor and memory, for example) on the server and displayed output is resent to the
user display screen. Multiple clients can connect to the server simultaneously.
Subnet
By definition, a subnet (short for sub-network) is an identifiably separate part of an organization’s
network. Typically, a subnet can represent all the machines (computers, laptops, handheld devices,
printers, etc.) at one geographic location, in one building, or on the same LAN. Having an
organization's network divided into subnets allows it to be connected to the Internet with a single
shared network address.
WLAN standards
IEEE wireless standards such as 802.11 have undergone many improvements and addendums since
they were first defined. The following list offers a high-level description of each of the better known
standards:
 802.11, which operates in the 2.4-GHz frequency band and offers only 2 megabits- per-
second (Mbit/s) of overall throughput, was the original implemented standard.
 802.11b is the most widely used form of wireless fidelity (Wi-Fi) today. The radio operates
within the 2.4-Ghz frequency band but allows a maximum data throughput of 11-Mbit/s.
 802.11a is a short range, but extremely high-speed Wi-Fi network. This standard is not
compatible with existing 802.11b networks. 802.11a operates in the 5-Ghz frequency
band and can transfer data at a maximum speed of 54-Mbit/s.
 802.11g is compatible with existing 802.11b networks, but also enables higher speeds. Its
maximum speed is 54-Mbit/s, but 802.11g operates in the 2.4-Ghz frequency band.
NOTE: The 54-Mbit/s maximum speed of 802.11g is reached only when the network contains
other 802.11g-based devices. Users who mix 802.11b devices in that network will see only a
maximum throughput value of 22 Mbit/s.
 The 802.1X standard defines the method of encapsulating Extensible Authentication Protocols
(EAPs) over wired or wireless Ethernet networks. This standard does not define any specific
security protocol, but is based on EAP types documented and ratified by the Internet
Engineering Task Force (IETF).
What is Roaming?
Roaming refers to the ability of a WLAN to switch between wireless access points to maintain a
WLAN connection as a user travels from one location to another. This access point switching, referred
to as roaming, occurs automatically and is normally transparent to the user.
Wireless connections roam from one access point to another when the detected signal strength
weakens. A weak signal in a Pocket PC triggers the handheld device to search for another signal to
“jump” to. The new signal is chosen from a list of preferred networks configured by the Wi-Fi user
interface in the device operating system.
Two basic roaming techniques are currently available: Address transition roaming and Location
transition roaming.
The Wireless LAN and HP iPAQ Pocket PCs 7

Devices using the address transition roaming technique briefly break their network connection when
roaming between (changing) access points. The Pocket PC immediately re-negotiates for a valid
address. The user’s ability to communicate is virtually guaranteed, but sessions open at the time the
network breaks will also disconnect. The address transition roaming technique is best suited to
networks that have access points on different sub-networks with different address ranges. The HP
iPAQ Pocket PC h5500 series supports this type of roaming.
The location transition roaming algorithm enables a handheld device to move seamlessly between
access points without disconnecting from the network. Using this roaming algorithm, a given device
will not change its address and devices will maintain sessions when roaming across access points on
the same subnet. Most shipping Wi-Fi devices support this roaming technique.
However, HP iPAQ Pocket PCs with zero-configuration-based Microsoft Windows Pocket PC
Operating Systems, allow WLAN connections to disconnect and reconnect when a new access point
is found. HP iPAQ Pocket PCs h4100, h4300, and h5400 series are affected by this anomaly.
HP-supported authentication wireless protocols
HP iPAQ Pocket PC h4100, h4300, h5400, and 5500 series handheld devices currently support the
following wireless authentication protocols:
 Lightweight Extensible Authentication Protocol (LEAP)
 Protected Extensible Authentication Protocol (PEAP)
 Transport Layer Security (TLS)
 Wired Equivalent Privacy (WEP)

LEAP
Cisco Compatible Extensions (CCXs) are a collection of authentication protocol features that
include some security enhancements. One part of this Cisco collection is LEAP. LEAP is not a true
Extensible Authentication Protocol (EAP)-type protocol; support for LEAP is found only in Cisco
access points and infrastructure. All HP iPAQ Pocket PCs that ship with Wi-Fi radios support
LEAP. Another aspect of CCX is Cisco Key Integrity Protocol (CKIP), which is a Cisco proprietary
implementation of temporal key support.
The Wireless LAN and HP iPAQ Pocket PCs 8

A LEAP-based network authenticates user credentials before allowing access to the network; inner
and outer authentications are not required. While this does reduce the overall infrastructure load,
there are some security concerns surrounding this implementation.
PEAP
PEAP uses digital certificates for network server authentication and passwords for client
authentication. PEAP requires an EAP user name, EAP password, and a Certificate of Authority
(CA). Dynamic encryption keys are also used in this authentication type.
802.1X EAP types: Protected EAP (PEAP)
Microsoft, Cisco, and RSA Security created this EAP type to reduce the certificate requirements
found in EAP-TLS. This EAP type uses a root server certificate in setting up the secure tunnel to the
authentication server. This allows user credentials to then be obtained and transmitted to the
authentication server. Unlike EAP-TLS, this protocol will authenticate the user, but not necessarily
the device.
TLS
TLS ensures Internet privacy between communicating applications and their users. When a server
and user communicate, TLS prevents a third party from eavesdropping or tampering with the
transmissions. TLS connection security uses an encryption method. TLS allows the server and user
to authenticate each other and to negotiate for an encryption algorithm and cryptographic keys
before data is exchanged.
802.1X EAP type: Transport Layer Security (EAP-TLS)
EAP-TLS utilizes a certificate pair for authentication. This EAP type was originally developed by
Microsoft and is used as a core component for the other EAP types listed below as a first line
authentication. This system uses a public/private key infrastructure to setup a secure conduit to
exchange the encryption keys. The exchange is very similar to the exchange used in a secure
web site (HTTPS.) The disadvantage to this protocol is the requirement for extensive certificate
management; this EAP type does not authenticate the user as much as it authenticates the device.
WEP
WEP encrypts data immediately before wireless transmissions are sent, and decrypts data it
receives. WEP security is considered the first significant line of defense against casual
eavesdroppers. If WEP uses a secret key, which is considered similar to a password, then the key
must be available on all of the network’s wireless devices.
Temporal Key Integrity Protocol (TKIP) technology improves WEP by using a per-packet key
mechanism, in which the base key is modified for each packet sent over the network. The overall
key length is extended to 256-bits for encryption.
NOTE: For additional information about the LEAP authentication protocol, refer to the Cisco
website: www.cisco.com
The following table lists HP iPAQ Pocket PC-supported wireless authentication protocols.
Then and now—HP iPAQ Pocket PC wireless
implementation
HP iPAQ Pocket PCs are designed to increase productivity by giving customers the ability to continue
working, even when their work takes them away from the office. Whether meeting in an office on the
The Wireless LAN and HP iPAQ Pocket PCs 9

other side of the company, across town at a customer site, at home working late, whatever the
reason, HP produces wireless and mobile devices to help customers expand their working world.
Today, HP engineering works continuously to provide enhancements, new functionality, and evolving
products that will keep customers on the cutting edge of the still emerging wireless technology.
A key component in enabling the HP wireless vision involves the process of roaming. Roaming is
discussed in more detail in the next section, but it is important to mention here.
HP iPAQ Pocket PC 4000 and 5000 series handheld devices were originally designed to disconnect
and reconnect during roaming between access points. While the design works flawlessly under
Address Transition roaming, it causes interruption to applications under Location Transition roaming.
HP engineering is approaching release of a solution to the roaming issue, which will soon be
available for download on the HP website at www.hp.com. (On the HP homepage, click Support &
Drivers, Handheld Devices then iPAQ Pocket PCs; select the series, and then download the drivers
and software).
NOTE: It is a good idea to periodically check the HP website for ROM update and SoftPaq releases.
HP engineering is working on a number of enhancements, updates, and fixes in addition to the
roaming issue.
ROM and driver updates
ROM updates often contain information that is more recent than that contained in the original ROM
release, or in the most recently updated version of the ROM (e.g., one or more ROM updates may
have already been released since the original ROM version). A ROM update can include driver
updates to either enhance or correct driver performance, software updates, and more.
Updates are released in one of two download types: RAM or Execute in Place (XIP). XIP updates are
permanent updates in the ROM.
ROM updates are language-specific, but may not be intended for all customers. If a ROM update
contains information that is not critical to the user, then the user may download it at a later date, or
not at all.
Determining the ROM release
To determine the most recent ROM release on an HP iPAQ Pocket PC, perform one of the following:
1. Soft-reset the device. The ROM version appears on the bottom right-hand corner of the screen.
2. On the Start screen, tap Start, Settings, tap the System tab, tap the Asset Viewer icon, tap the
“+” sign next to Version. The ROM Revision and revision date appear, along with operating
system information.
The WLAN and HP iPAQ Pocket PCs
Turning on and off the WLAN
NOTE: Minor differences exist in the basic operation of the HP iPAQ Pocket PC h5400 series; some
have the Microsoft Windows Pocket PC 2003 Operating System via an update, and some with the
Microsoft Windows Pocket PC 2002 Operating System, with which they were originally shipped. For
this reason, the h5400 series instructions are separated as such.
