							3 Wireless and local area networks
Using wireless devices
Wireless technology transfers data across radio waves instead of wires. Your computer may be
equipped with one or more of the following wireless devices:
●Wireless local area network (WLAN) device—Connects the computer to wireless local area
networks (commonly referred to as Wi-Fi networks, wireless LANs, or WLANs) in corporate offices,
your home, and public places such as airports, restaurants, coffee shops, hotels, and universities.
In a WLAN, each mobile wireless device communicates with a wireless router or a wireless access
point.
●HP Mobile Broadband Module—A wireless wide area network (WWAN) device that provides
access to information wherever mobile network operator service is available. In a WWAN, each
mobile device communicates to a mobile network operator’s base station. Mobile network operators
install networks of base stations (similar to cell phone towers) throughout large geographic areas,
effectively providing coverage across entire states, regions, or even countries.
●Bluetooth® device—Creates a personal area network (PAN) to connect to other Bluetooth-enabled
devices such as computers, phones, printers, headsets, speakers, and cameras. In a PAN, each
device communicates directly with other devices, and devices must be relatively close together—
typically within 10 meters (approximately 33 feet) of each other.
Computers with WLAN devices support one or more of the following IEEE industry standards:
●802.11b, the first popular standard, supports data rates of up to 11 Mbps and operates at a
frequency of 2.4 GHz.
●802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g
WLAN device is backward compatible with 802.11b devices, so they can operate on the same
network.
●802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz.
NOTE:802.11a is not compatible with 802.11b and 802.11g.
●802.11n supports data rates of up to 450 Mbps and may operate at 2.4 GHz or 5 GHz, making it
backward compatible with 802.11a, b, and g.

Using a WLAN
With a WLAN device, you can access a wireless local area network (WLAN), which is composed of other
computers and accessories that are linked by a wireless router or a wireless access point.
NOTE:The terms wireless router and wireless access point are often used interchangeably.
●A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points
that can accommodate a large number of computers and accessories and can separate critical
network functions.
●A home or small office WLAN typically uses a wireless router, which allows several wireless and
wired computers to share an Internet connection, a printer, and files without requiring additional
pieces of hardware or software.
To use the WLAN device in your computer, you must connect to a WLAN infrastructure (provided through
a service provider or a public or corporate network).
Setting up a WLAN
To set up a WLAN and connect to the Internet, you need the following equipment:
●A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from an
Internet service provider (ISP)
●A wireless router (purchased separately) (2)
●The wireless computer (3)
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
As your network grows, additional wireless and wired computers can be connected to the network to
access the Internet.
For help in setting up your WLAN, refer to the information provided by your router manufacturer or your
ISP.
Protecting your WLAN
Because the WLAN standard was designed with only limited security capabilities—basically to foil casual
eavesdropping rather than more powerful forms of attack—it is essential to understand that WLANs are
vulnerable to well-known and well-documented security weaknesses.
WLANs in public areas, or “hotspots,” like coffee shops and airports may not provide any security. New
technologies are being developed by wireless manufacturers and hotspot service providers that make
the public environment more secure and anonymous. If you are concerned about the security of your
computer in a hotspot, limit your network activities to noncritical e-mail and basic Internet surfing.
16 Chapter 3   Wireless and local area networks 
						

							When you set up a WLAN or access an existing WLAN, always enable security features to protect your
network from unauthorized access. The common security levels are Wi-Fi Protected Access (WPA)-
Personal and Wired Equivalent Privacy (WEP). Because wireless radio signals travel outside the
network, other WLAN devices can pick up unprotected signals and either connect to your network
(uninvited) or capture information being sent across it. However, you can take precautions to protect
your WLAN:
●Use a wireless transmitter with built-in security
Many wireless base stations, gateways, or routers provide built-in security features such as
wireless security protocols and firewalls. With the correct wireless transmitter, you can protect your
network from the most common wireless security risks.
●Work behind a firewall
A firewall is a barrier that checks both data and requests for data that are sent to your network,
and discards any suspicious items. Firewalls are available in many varieties, both software and
hardware. Some networks use a combination of both types.
●Use wireless encryption
A variety of sophisticated encryption protocols is available for your WLAN. Find the solution that
works best for your network security:
◦Wired Equivalent Privacy (WEP) is a wireless security protocol that encodes or encrypts all
network data before it is transmitted using a WEP key. Usually, you can allow the network to
assign the WEP key. Alternatively, you can set up your own key, generate a different key, or
choose other advanced options. Without the correct key, others will not be able to use the
WLAN.
◦WPA (Wi-Fi Protected Access), like WEP, uses security settings to encrypt and decrypt data
that is transmitted over the network. However, instead of using one static security key for
encryptions as WEP does, WPA uses “temporal key integrity protocol” (TKIP) to dynamically
generate a new key for every packet. It also generates different sets of keys for each computer
on the network.
Roaming to another network
When you move your computer within range of another WLAN, Windows attempts to connect to that
network. If the attempt is successful, your computer is automatically connected to the new network. If
Windows does not recognize the new network, follow the same procedure you used initially to connect
to your WLAN.
Using HP Mobile Broadband (select models only)
HP Mobile Broadband enables your computer to use wireless wide area networks (WWANs) to access
the Internet from more places and over larger areas than it can access by using WLANs. Using HP
Mobile Broadband requires a network service provider (called a mobile network operator), which in most
cases is a mobile phone network operator. Coverage for HP Mobile Broadband is similar to mobile phone
voice coverage.
When used with mobile network operator service, HP Mobile Broadband gives you the freedom to stay
connected to the Internet, send e-mail, or connect to your corporate network whether you are on the
road or outside the range of Wi-Fi hotspots.
Using HP Mobile Broadband (select models only) 17 
						

							HP Mobile Broadband supports the following technologies:
●HSPA (High Speed Packet Access), which provides access to networks based on the Global
System for Mobile Communications (GSM) telecommunications standard.
●EV-DO (Evolution Data Optimized), which provides access to networks based on the code division
multiple access (CDMA) telecommunications standard.
You may need the HP Mobile Broadband Module serial number to activate mobile broadband service.
The serial number is printed on a label inside the battery bay of your computer.
Some mobile network operators require the use of a subscriber identity module (SIM). A SIM contains
basic information about you, such as a personal identification number (PIN), as well as network
information. Some computers include a SIM that is preinstalled in the battery bay. If the SIM is not
preinstalled, it may be provided in the HP Mobile Broadband information included with your computer,
or the mobile network operator may provide it separately from the computer.
For information on inserting and removing the SIM, refer to the “Inserting a SIM” and “Removing a SIM”
sections in this chapter.
For information on HP Mobile Broadband and how to activate service with a preferred mobile network
operator, refer to the HP Mobile Broadband information included with your computer. For additional
information, see the HP Web site at 
http://www.hp.com/go/mobilebroadband (US only).

Using Bluetooth wireless devices
A Bluetooth device provides short-range wireless communications that replace the physical cable
connections that traditionally link electronic devices such as the following:
●Computers (desktop, notebook, PDA)
●Phones (cellular, cordless, smart phone)
●Imaging devices (printer, camera)
●Audio devices (headset, speakers)
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information on configuring and using Bluetooth devices, refer to the
Bluetooth software Help.
Bluetooth and Internet Connection Sharing (ICS)
HP does not recommend setting up one computer with Bluetooth as a host and using it as a gateway
through which other computers may connect to the Internet. When two or more computers are connected
using Bluetooth, and Internet Connection Sharing (ICS) is enabled on one of the computers, the other
computers may not be able to connect to the Internet using the Bluetooth network.
The strength of Bluetooth is in synchronizing information transfers between your computer and wireless
devices including cellular phones, printers, cameras, and PDAs. The inability to consistently connect
two or more computers to share the Internet through Bluetooth is a limitation of Bluetooth and the
Windows operating system.
