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
  
  
  

Q . Can Wi-Fi (WLAN) and Bluetooth connections coexist?
A . Bluetooth 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 hx2000 series has software that eliminates the co-existence issue between WLAN and Bluetooth. In the iPAQ Pocket PC, WLAN and Bluetooth connections can be established at the same time without disconnections.


Q . Are HP Wi-Fi (WLAN) products interoperable with other product brands?
A . 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.


Q . What is the data throughput speed of an 802.11b WLAN network connection?
A . 802.11b WLANs operate up to speeds of 11 Mbps. WLAN users experience speed comparable to that offered by many-wired networks. Similar to the wired network, WLAN throughput speed depends on such factors as network topology, load, and distance from the access point.


Q . What is a Hot Spot?
A . 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.


Q . What is Ad-Hoc mode?
A . 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.


Q . What is Network Infrastructure mode?
A . 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.

Q . What are the requirements for WLAN connectivity?
A . A standard WLAN infrastructure (access points), other Bluetooth enabled devices, separately purchased equipment 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.

Q. What can I do with Bluetooth?

• Cable-free communication in and out of the office.
  

Q . What Bluetooth devices will work with the iPAQ hx2000 series Pocket PC?
A . The Bluetooth specification uses profiles to identify special services that can be implemented by individual Bluetooth products. A Bluetooth 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 is why HP has created a Bluetooth Compatibility Matrix to help customers identify products that work well with HP Bluetooth products. See the Bluetooth Compatibility Matrix at Bluetooth Compatibility Matrix.

Improved data encryption through the temporal key integrity protocol (TKIP). TKIP scrambles the keys using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys have not been tampered with.

User authentication through the extensible authentication protocol (EAP). WEP regulates access to a wireless network based on a computer’s hardware-specific MAC address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized network users can access the network.


Q . What is a VPN?
A . 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.
