Chapter 1 INTRODUCTION AirEZY-2411-BT is an 802.11b compliant, or WiFi, radio with a 10-BaseT interface. 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 PCMCI

Chapter 2 INSTALLATION Installing the Hardware Power This radio is capable of pulling power from either an AC adapter (supplied with the standard purchase) that plugs into a wall outlet or from the USB or the PS2 port of a notebook computer through special adapter cables (call OTC to find out more about these optional cables), or through a battery pack. Power can also be supplied to the AirEZY-2411-BT over the Ethernet cable with the used of an optional dc-extractor box near the r

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 Screen-Shot #3 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

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. SSID: Service Set Identity is used by a station radio when issuing Association/Re-association Requests to the Access Point. The Access Point uses the match of the SSID as one of the optional conditions for granting

The tightest level of network access control is implemented in Level 3, [Hide SSID, Match SSID, Use Allowed List], add one additional criterion for a Station to gain access to the network associated with this AP—its MAC address must appear in the “Allowed Station List” (see below) shown in the lower-right corner of this sub-tab.

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. The default value is set at 2436 bytes, the maximum 802.11 data frame size, such that no frames are ever fragmented

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 is on top after clicking the “Configuration” tab.

PS Mode: Power Saving can be enabled only when “Infrastructure” is selected for the “Network Type”. Channel: This field is modifiable only when the “Ad hoc” type is selected for “Network Type”. The Station automatically scans for the right channel to join when operated in the “Infrastructure” mode. In the “Ad hoc” mode, the Station also automatically scans for the right channel to join an existing “ad hoc” Service Set. However, when the Station is the first station to start an ad hoc n

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. (See screen-shots #9 and #10, the display in screen-shot #10 is dimmed and not modifiable.) These displayed keys can be copied down and manually entered for radios other than AirEZY-2411-BT to assure interoperability. Clicking the b

Note that once the Dynamic WEP Key is in force, the Transmission Key Selection (Screen Shot#12) made by the user is only used in the authentication process and is irrelevant in the encryption of transmitted data.

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. If the radio’s role is AP, the “Link Quality” and “Signal Strength” are not displayed (Screen Shot #14). View Packet Statistics In ad
