Page 4: Chapter 1 Introduction
Two features separate AirEZY-2411-BT from many other 802.11b-compliant radios. Firstly, this 802.11b-compliant (WiFi) radio can be configured as either a Station (ACR-201) or an AP (ASR-102). Secondly, when configured as a Station, the 10-BaseT interface affords it a true plug-and-play feature that is unavailable from any other 802.11b Station radios are based on either a PCMCIA... -

Page 9: Installing The Utility Software
Installing the Utility Software System Requirements To use the AirEZY-2411-BT Wireless Ethernet Adapter’s utilities software, your computer must meet the following minimum requirements: Windows® 95 (OSR2)/ 98 (SEC)/ME/2000/XP Ethernet capable computer with RJ-45 port (either built-in or add-on NIC) Installation To install the utility program, simply insert the CD-ROM provided and the installation process will finish with you clicking a few “OK”. -

Chapter 3 Use the Utility Program Once the radio is properly turned on and connected either directly to the Screen-Shot #1 Clicking the OK button signals the successful completion of the use of the Utility program. The program applies the modifications made to all tabs and exits. Clicking the Exit button exits the program without changing the setting of the radio. -
Page 11: Configure Airezy-2411-Bt As An Access Point (Asr-102)
Configure AirEZY-2411-BT as an Access Point (ASR-102) By checking the “Change Role to AP” (red-arrowed in screen-shot #3), most Screen-Shot #2 parameter fields become undimmed and modifiable, as seen in screen-shot #3 . With the exception of the “MAC” field, and sometimes the “Allowed Station List” field, each filed can be modified and uploaded into the radio by clicking the Apply button without exiting the program, or by clicking the OK button right before exiting the program. - Page 12 Each field on this “Access Point” sub-tab is explained below. Device Name: Allows the user to enter a user- defined name for the radio. Up to 32 bytes can be used. MAC: Displays the MAC address of the radio when it is configured as an AP. This filed cannot be modified.

Fragmentation Threshold: In the presence of hostile RF environment, such as interference, frames longer than this threshold numbers in bytes are divided prior to transmission into one or more fragments equal in length to the fragmentation threshold.

Configure AirEZY-2411-BT as a Station (ACR-201) Click on the “Station” sub-tab to display the “Station” page if the “Access Point” page after clicking “Configuration” tab. Similar to the case of configuring the radio for AP, checking the “Change Role to Station” undims the page and makes most fields modifiable. -

The Station automatically scans for the right channel to join when operated in the “Infrastructure”... - Page 17 applied to other Wi-Fi radios, however, may result in very different keys. For this reason, clicking the Apply button after entering the pass-phrase will cause the 4 sets of keys being temporarily displayed under “Manual Entry” as if they were entered manually.

transmitted data packets. “Signal Strength” directly measures the amount of RF energy received relative to a “maximum” expected for the best condition. The two measures are related, but could differ due to various reasons. In general, as a first step toward maximizing Link Quality, one should try to maximize the Signal Strength by moving the radio around. -

Page 27: Glossary
GLOSSARY 10BaseT An IEEE standard (802.3) for operating 10 Mbps Ethernet networks (LANs) with twisted pair cabling and a wiring hub. Access Point An internetworking device that seamlessly connects wired and wireless networks. Access Points combined with a distributed system support the creation of multiple radio cells that enable roaming throughout a facility. - Page 28 Hidden Node The situation where two or more radios in a multiple-radio network fail to detect the RF signals from each other. For example, in a 3-radio network, radio 2 and 3 both have good link to radio 1. Radio 2 and 3, however, are isolated from each other by, say, a metal wall.

These cards are available in three types, and are about the same length and width as credit cards. However, the different cards range in thickness from 3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type III).
