OTC Wireless ACR-201, ASR-102 specification

Screen-Shot #6

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 or refuting association. (See more on this topic in “Enhanced Sec.” below.) A Manager/operator of the network chooses this SSID. When a SSID is first introduced, it needs to be manually typed in. After a SSID is used once, the Utility program remembers the SSID and allows it to be selected out of the pull- down list for re-use. The special SSID name “any”, once selected, allows an AirEZY 2411 BT to wander across Service Sets with different SSID’s without the need to manually obtain and reset the SSID every time. Whether the Station radio’s association request is accepted or rejected by an AP, however, is entirely determined by the local network management, not guaranteed by the use of “any” as the SSID. When “any” is chosen, the SSID field display turns blank. The special role of “any” works only in the Infrastructure mode.

Enhanced Sec.: There are two aspects to the security of a WiFi radio network: access control and data encryption.

More details on data encryption are given in the section discussing Encryption. Independent of whether data encryption is used or not, the access of a Station to the network can be restricted. The AirEZY-2411-BT Access Point can be set up to offer four different levels of access control for the wireless network associated with it. Refer to screen-shot #6, a pull- down menu is used to select the level of network security. Level 0, [Disabled], basically leaves the access to the network entirely open. Stations with “any” (see the section “Configuration the AirEZY-2411-BT as a Station” for more explanations) as the SSID, for example, is allowed to

join without any restriction. Selecting Level 1, [Hide SSID in Beacon], causes the AP radio to send beacons without the SSID. This minimizes the chance for an eavesdropping radio to capture and utilize the SSID for more damaging intrusion to the network. At Level 2, [Hide SSID, Match exact SSID], this AP grants a Station association only when the Station submits in its association request
