ASCII is the acronym for the

American Standard Code for Information Interchange

. Pronounced

ask-ee

, ASCII is a code for

representing English characters as numbers, with each letter assigned a number from 0 to 127. For example, the ASCII code

for uppercase

M

is 77. Most computers use ASCII codes to represent text, which makes it possible to transfer data from one

computer to another.

WPA

WPA is an upgrade to the WEP (Wired Equivalent Privacy) standard for securing your wireless network. WPA is derived from

and will be forward-compatible with the future IEEE 802.11i standard. It provides improved data encryption and user

authentication.

To enhance the level of security, WPA uses TKIP (Temporal Key Integrity Protocol) encryption to address the vulnerabilities of

the static keys used in WEP (Wired Equivalent Privacy). TKIP includes four algorithms: MIC (message integrity check), to

protect packets from tampering; PPK (Per-Packet Key) hashing, to prevent weak key attacks; extended IV (initialization vector),

to reduce IV reuse and the possibility that a hacker will collect sufficient packets to crack the encryption; and a re-keying

mechanism, to change the temporal key dynamically. TKIP is the most commonly used encryption method; however, if your

wireless clients do not support TKIP, TrueMobile 2300 also supports AES (Advanced Encryption Security) encryption. AES will

replace 802.11's RC4-based encryption under 802.11i specification. AES, the gold-standard encryption algorithm, provides

maximum security for wireless network.

For user authentication, WPA adopts an authentication scheme -- via 802.1x. 802.1x provides a framework for user

authentication and a key distribution management method. 802.1x consists of three main elements: an Authentication Server

(typically a RADIUS server), WPA-enabled router or AP (called "

Authenticator

"), and a WPA-enabled client (called

"

Supplicant

"). 802.1x ensures only authorized users can access the network.

In enterprises, WPA will be used in conjunction with both wireless router and authentication server. In Small Office/ Home

Office (SOHO) environment, where there are no authentication server, users can use pre-shared key (PSK) mode in place of

the authentication server. TrueMobile 2300 offers you WPA running in PSK mode. The mutual authentication and improved

encryption technology of WPA allows wireless communication to achieve greater security.

Automatic Rate Selection and Rate Scaling

In 802.11g, wireless network adapters and access points can transmit data at one of the following rates: 54, 48, 36, 24, 18, 12,

9, or 6 Mbps. In 802.11b, the data can be transmitted at a rate of 11, 5.5, 2, or 1 Mbps. As the distance between an adapter

and access point increases or decreases, the data rate automatically changes. Other factors, like interference, also affect the

data rate. The Wireless Broadband Router uses automatic rate selection and rate scaling to determine the most efficient rate of

communication. Rate scaling maintains optimal communication between wireless clients and the WLAN.

Setup Wizard: Dell™ TrueMobile™ 2300 Wireless Broadband

Router User's Guide

Introduction

Launch the Setup Wizard

Setup Wizard Screens

Introduction

Setup Wizard is an easy-to-use program included on your TrueMobile 2300 CD. It provides simplified configuration procedures

for establishing Internet connectivity on the Wireless Broadband Router. The Setup Wizard first extracts the connection settings

from your active ISP connection on your PC with Cable/DSL modem. It then displays a series of graphical illustrations on how

to connect the router to the network. Finally it applies the extracted settings on your router and validate its installation.

If the

installation cannot be completed successfully, the Setup Wizard will display troubleshooting instructions to guide you through

the installation process.

In addition, the Setup Wizard also provides links to the User's Guide on the TrueMobile 2300 CD and also the Dell support

website.
