HP iPAQ Pocket PC h4100 series - The new iPAQ Pocket PC h4100 series is affordable integrated wireless in a slim
design. At an outstanding value, the HP iPAQ Pocket PC h4100 series allows you to stay connected at work, at home, or
on the go.
HP iPAQ Pocket PC h4300 series - The new iPAQ Pocket PC h4300 series is affordable integrated wireless with built-in
backlit keyboard for effortless messaging, emailing, and note inputting. At an outstanding value, the iPAQ Pocket PC
h4300 series maximizes productivity at work, at home, or on the go.
Both include integrated WLAN (Wireless Local Area Network) 802.11b and Bluetooth® wireless technology, so you can
access the Internet, e-mail, and information when you want. A powerful, removable battery enables the devices to run
longer, and an industry-standard SD slot provides options for more expansion and information storage.
Why did HP select 802.11b versus 802.11a or 802.11g?
We chose to integrate 802.11b for the wide market availability, the main system power needs, and small form factor.
802.11a is an extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band. 802.11a
also has a shorter range and is less power efficient. 802.11g applies to wireless LANs and provides 20+ Mbps in the
2.4 GHz band.
Why did HP decide to integrate a keyboard on the iPAQ h4350?
The integrated keyboard with backlight on the iPAQ Pocket PC h4350 allows for effortless messaging, emailing, and note
inputting. Integrating the keyboard into the unit provides a better messaging and seamless user experience.
Can I use any of the iPAQ Pocket PC h4100/h4300 models as a phone?
No, the iPAQ Pocket PC h4100/h4300 models have integrated wireless LAN technology, which requires an 802.11b
infrastructure in place for connectivity. Therefore, this device is intended for data use, as opposed to voice phone
communications. The exception to this might be the use of a separately purchased Voice Over IP software application,
which allows you to use this device as a VoIP phone in an 802.11b WLAN environment.
What are the benefits of integrating WLAN into the Pocket PC?
HP continues to integrate new technologies to provide the optimal user experience. We listen to our customers and
integrate the most universally needed technologies. In addition to integrated solutions, we also provide modular
ones. Some users prefer to select and configure their own solutions using iPAQ Pocket PC accessories. Advantages to
having WLAN technology integrated include:
- Smaller, lighter
- Lower Total Cost of Ownership
- Easier deployment/distribution/management
- Easier to hold/more "pocketable"
- More expandable (can still use expansion packs)
- Fewer pieces to lose; fewer pieces to break; fewer assets to track
- Better power management
What is a Wireless LAN (WLAN)?
A WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to communicate and
transmit data among nodes. It is a flexible data communication system implemented as an extension to, or as an
alternative for, a wired LAN within a building or campus. It is also known as Wi-Fi.
Can WLAN and Bluetooth® enabled connections coexist?
Bluetooth wireless technology and 802.11 use different radios. The distance between the two antennas will determine
the level of interference or coexistence of the two radios within the same product. The h4100 and h4300 have software
that eliminates the co-existence issue between WLAN and Bluetooth technology. In the iPAQ Pocket PC, WLAN and Bluetooth
wireless connections can be established at the same time without disconnections.
Are HP WLAN products interoperable with other product brands?
Yes. HP WLAN products are compatible with products from different vendors employing the same technology (for example,
Direct Sequence Spread Spectrum). This compatibility allows users to use client adapters from multiple vendors. The
goal of industry standards, including the IEEE 802.11 specifications, is to allow compliant products to interoperate
without explicit collaboration between vendors. WECA (Wireless Ethernet Compatibility Alliance) is an industry
organization that certifies WLAN product interoperability. The 802.11b specification provides the guidelines for
WLAN interoperability, and the Wireless Ethernet Compatibility Alliance (WECA) ensures that products interoperate in
real-world applications. Systems can interoperate as long as the PC client card and access point are 802.11b compliant
and WECA certified.
What is the data throughput speed of an 802.11b WLAN network connection?
802.11b WLANs operate up to speeds of 11 Mbps. WLAN users experience speed comparable to that offered by many-wired
network. Similar to the wired network, WLAN throughput speed depends on such factors as network topology, load, and
distance from the access point.
What is a Hot Spot?
A hot spot is a place where you can access WLAN/Wi-Fi service, either free or fee-based. Hot spots can be inside a
coffee shop, airport lounge, train station, convention center, hotel or any other public meeting area. Corporations
and campuses are also implementing hot spots to provide wireless Internet access to their visitors and guests. In some
parts of the world, hot spots are also known as cool spots.
What is Ad-Hoc mode?
Ad-Hoc mode is a profile setting that provides independent peer-to-peer connectivity. In Ad-Hoc mode you can connect
to other WLAN enabled devices without the need of an access point.
What is Network Infrastructure mode?
Network Infrastructure mode is a client setting providing connectivity to an Access Point. As compared to Ad-Hoc mode,
whereby devices communicate directly with each other, a Profile set in Infrastructure Mode must pass data through a
central Access Point. The Access Point not only mediates wireless network traffic in the immediate neighborhood, but also
provides communication with the wired network.
PCs communicate directly with each other; clients set in Infrastructure mode all pass data through a central Access
Point. The Access Point not only mediates wireless network traffic in the immediate neighborhood, but also provides
communication with the wired network.
What are the requirements for WLAN connectivity?
A standard WLAN infrastructure (access points), other devices enabled with WLAN (802.11b), and a service contract with
a wireless airtime provider may be required for applicable wireless communication. Wireless Internet use requires a
separately purchased service contract. Check with a service provider for availability and coverage in your area. Not
all Web content available.
What version of Active Sync works with Microsoft Windows Mobile 2003 software?

What Bluetooth enabled devices will work with the iPAQ Pocket PC h4100/h4300 series?
The Bluetooth technology specification uses profiles to identify special services that can be implemented by individual
Bluetooth enabled products. A Bluetooth enabled device can implement one or many profiles, depending on the
functionality it desires. Two devices can only perform activities with each other if they both support a common
profile. That’s why HP has created a Bluetooth Compatibility Matrix to help customers identify products that work well
with HP Bluetooth enabled products. See the
Bluetooth Compatibility Matrix.
What Bluetooth wireless technology profiles are supported in the iPAQ Pocket PC h4100/h4300 series?

Is LEAP supported on the iPAQ Pocket PC h4100/h4300 series?
The Cisco Lightweight Extensible Authentication Protocol (LEAP) is supported on the h4100/h4300 series for customers
whose networks support this feature. LEAP is a wireless technology that is built on the 802.1X authentication for
local area networks (LANs), which allows users to roam freely and not to be tied to any one specific domain or
rotation of encrypted security keys.
What is 802.1X and is it supported?
The h4100/h4300 series supports the IEEE 802.1X standard for wireless encryption for customers whose networks support
this feature. This security standard controls access to a wireless network by varying encryption keys using the
Extensible Authentication Protocol (EAP). Pocket PC 2003 supports Transport Layer Security (TLS) and Microsoft's
Protected EAP (PEAP) implementation of 802.1X. Both implementations require an enroller to retrieve the appropriate
certificates from a central certificate authority (CA) onto your Pocket PC. The enroller is included in the ROM for
the h4150/h4350 series.
What is WEP and is it supported?
Wired Equivalent Privacy (WEP) is a basic wireless security provided by Wi-Fi. In some instances, WEP may be all a
home- or small-business user needs to protect wireless data. WEP is supported in 64-bit and 128-bit encryption modes.
As 128-bit encryption provides a longer algorithm that takes longer to decode, it can provide better security than
basic 64-bit encryption. Pocket PC 2003 supports WEP.
What is a VPN?
Virtual Private Network (VPN) is a type of technology designed to increase the security of information transferred over
the Internet. VPN works with either wired or wireless networks, as well as with dial-up connections. VPN creates a
private encrypted tunnel from the end user's computer, through the local wireless network, through the Internet, to the
corporate servers and database.
What is the difference between reflective and transflective display?
Reflective is front-lit active matrix display viewable by utilizing internal or external light source, ideal for indoor
or outdoor use. The rear polarizer of a reflective display includes a diffuse reflector. This layer reflects polarized
ambient light that has entered the front of the display back through the LCD cell. Reflective displays require ambient
light to be seen, with high brightness, excellent contrast (14:1), and wide viewing angles. iPAQ Pocket PCs using the
reflective LCD's are front-lit.
Transflective display combines transmissive and reflective technologies utilizing internal or external light source.
Transmissive displays have a clear polarizer on the front and the back. The display depends on light coming through from
the back of the display toward the user. Reflective displays reflect polarized ambient light that has entered the front
of the display back trough the LCD cell.
The benefits of transflective display are crisper images and clearer text, with rich color saturation.
