The TrueMobile solution accesses wireless local area networks (WLANs),
enables the sharing of a local printer and files with others in the network,
enables Internet connection sharing, and enables roaming about the office—wire-free.
This wireless LAN solution is designed for both the home user and businesses—and
it is scalable so that users can be added and new network features can be enabled
as networking needs grow.
The WPA (Wi-Fi Protected Access) protocol is a powerful, standards-based, interoperable
security technology for wireless local area networks (subset of IEEE Std 802.11i
draft standard) that encrypts data sent over radio waves. The WPA protocol has
been developed to overcome the weaknesses of the WEP (Wired Equivalent Privacy)
protocol. Both protocols require the use of network key information, and either
protocol can be enabled or disabled, depending on the type of network connection
being made.
If the network being connecting to has enabled WPA or WEP, WPA or WEP must
also be enabled in the network profile configured on the notebook. Also, the
network key information used to configure a network on the notebook must be
set to match the network key information used by the network being connected
to. Otherwise, it is impossible for the notebook to connect to the network.
The TrueMobile enabled notebook makes a wireless connection to a network,
as illustrated on the following figure. Upon startup, the enabled notebook detects
certain WLANs (wireless networks) that are within range. Before connecting to
these and other wireless networks, a user must configure a profile for each
network. See Completing the Setup.
Networks 1 and 2 are infrastructure types of networks. The two notebook computers
connected by radio waves form an ad hoc type of network.
Enterprise Users
Obtain the following information from the network administrator:
Network names (SSID) of the specific wireless networks to connect to
WPA (Wi-Fi Protected Access) wireless network key information (network authentication
type, encryption type, network key, Light Extensible Authentication Protocol
(LEAP) username, LEAP password) for any WPA enabled networks you want to connect
to
WEP (Wired Equivalent Privacy) wireless network key information (network
key) for any WEP enabled networks you want to connect to
For Microsoft Windows networking, the customer name and workgroup name
For a network account, the domain name, a user name and password
An IP address (if not using a DHCP server)
If any of the networks are connected to an authentication server
Small Office/Home Office Users
The AP (access point) that communicates with the TrueMobile enabled
notebook has a preassigned network name (SSID) that the notebook recognizes
upon startup. If you are setting up a new wireless network, to enable WEP security,
use any string of characters for the network key. If you are connecting to an
existing WEP enabled network, obtain the network key from the AP installer.
If you are connecting to a WPA enabled AP, obtain the WPA (Wi-Fi Protected Access)
wireless network key information (network authentication type, encryption type,
network key, LEAP username, LEAP password) from the AP installer.
Using the TrueMobile Enabled Notebook
The TrueMobile enabled notebook is a wireless LAN device based on the
IEEE 802.11 standard. A LAN is composed of two or more computers that are connected
to each other to share files or common equipment such as a printer or an Internet
connection. A wireless LAN provides the same functionality of a wired network,
but it eliminates the need to install networking cables and other networking
equipment. Not only is a wireless LAN easier to deploy, but it also allows for
roaming. For example, when using the TrueMobile enabled notebook, it
is possible to roam from one room in the house to another, or from a conference
room to an office without being disconnected from the network.
Features
The TrueMobile solution is an IEEE 802.11 standard-based wireless LAN
that includes the following features:
Support for IEEE 802.11g draft specification
Support for IEEE 802.11a standard
Support for IEEE 802.11b standard
2.4-GHz band operation (TrueMobile 1180 and TrueMobile 1300)
5-GHz band operation (TrueMobile 1400)
Network data rate of up to 54 Mbit/s
Wi-Fi Protected Access (WPA) encryption (only for Windows XP environment)
Wired Equivalent Privacy (WEP) encryption
The TrueMobile enabled notebook works with any IEEE 802.11b Wi-Fi CERTIFIED®
or IEEE 802.11g access point or wireless client network adapter.
