Figure 3-4 Wireless LAN Cards Monitor Utility ­ Statistics 25 11Mbps Wireless LAN Card User's Manual Site Survey Site Survey function scans the wireless network searching for available Access Points and wireless stations (Ad-hoc mode) within the range of the card. Available stations are listed with the following information: BSSID: Basic Service Set ID. It is actually the MAC address of the Access Point/wireless station (Ad-hoc mode). It can be used to identify the stations when they have the same SSID. Displays the current SSID of the Access Point/wireless station (Ad-hoc mode). Signal: Shows the signal strength ratio. The higher the ration is, the more powerful the signal received by your Wireless LAN Card. It helps you identify the quality network operation. Ch (Channel): The operating radio channel number. WEP: Displays if encryption is enabled or disabled on the Access Point/wireless station (Adhoc mode). Type: Indicates whether the operating mode is Infrastructure ( Access Point) or Ad-Hoc (wireless station). Re-Scan: This button allows you to update the list. 26 Chapter 3 Wireless LAN Cards Monitor Utility Connecting to Desired Site By Site Survey Utility If you want to connect to any of the Access Point(s) and Ad-Hoc Station(s) listed, doubleclick on your choice (on the BSSID field).

[. . . ] In this environment, the Access Point not only provides communication with the wired network but also mediates wireless network traffic in the immediate neighborhood. The standard protocol within TCP/IP that defines the basic unit of information passed across an Internet connection by breaking down data messages into packets, routing and transporting the packets over network connections, then reassembling the packets at their destination. IP corresponds to the network layer in the ISO/OSI model. Gateway IEEE 802. 11 Infrastructure IP 74 Glossary IP Address An IP address is a 32-bit number that identifies each sender or receiver of information sent across the Internet. An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. [. . . ]
