What is a WLAN?

This section includes the following topics:

Overview

•

• Wireless fidelity

Overview

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 wireless 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 illustrates a WLAN setup with an access point.

Figure 1. WLAN with access point

Note: Signal strength can be reduced by conditions such as wireless interference, obstructions (walls, for instance), and signal

reflection. The radius listed represents the maximum distance an unenhanced WLAN signal can travel under prime operating conditions.

Wireless fidelity

Wi-Fi, also known as 802.11, is a communication standard created by the Institute of Electrical and Electronic Engineers (IEEE). The 802.11 standard defines the electrical and radio frequency components of a wireless Ethernet. This standard also defines an encryption algorithm (Wired Equivalent Privacy, or 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 can 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

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 rx3000, h4100, h4300, hx4700, h5400, h5500, or h6300 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

Use the next few sections to become familiar with the following terms as you begin to use wireless technology. This section includes the following topics:

Access points

•

Virtual private network

•

Voice over IP

•

Terminal Services client Subnet

•

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.

Terminal Services client

The Terminal Services client establishes a session with the server. User keyboard and mouse activity is sent by way of a 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 subnetwork) 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 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. This high-speed Wi-Fi network 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 obtained only when the network contains other 802.11g-based devices. Users who mix 802.11b devices in that network will see a maximum throughput value of only 11 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 an HP iPAQ 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.

Devices using the address transition roaming technique briefly break their network connection when roaming between (changing) access points. The HP iPAQ immediately renegotiates 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 subnetworks with different address ranges. The HP iPAQ 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 handheld devices 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 h4100, h4300, rx3000, hx4700, and h5400 series are affected by this anomaly.

HP supported authentication wireless protocols

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 EAP type protocol, as such LEAP authentication is not supported in networks using WPA/WPA-PSK encryptions; support for LEAP is found only in Cisco access points and infrastructure. All HP iPAQ handheld devices 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.

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.

For additional information about the LEAP authentication protocol, refer to the Cisco web site:

www.cisco.com.

PEAP

802.1X EAP type 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.

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.

EAP-TLS

802.1X EAP type Transport Layer Security (EAP-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. A TLS connection 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.

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.

Then and now—HP iPAQ wireless implementation

HP iPAQ handheld devices 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 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 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 has released a solution to the roaming issue, which will soon be available for download on the HP web site at Troubleshooting, Handheld Devices, and 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 web site for ROM updates 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 (for example, one or more ROM updates could 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 might 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.

Use one of the following methods to determine the most recent ROM release on an HP iPAQ handheld device:

• Perform a soft reset on the device. The ROM version appears on the bottom right-hand corner of the screen.

• On the Start menu, tap Start > Settings > System tab. Tap the Asset Viewer icon, and then tap the + sign next to Version. The ROM revision and revision date appear, along with operating system information.
