Table 4-2 Utiltity ­ Access Point Browser Screen Menu Fields ITEM SS_ID BSS_ID Channel Capability DESCRIPTION The SS ID (Service Set ID or MAC address) of the Access Point. The BSS ID (Basic Service Set ID) of the Access Point. The operating channel of the respective Access Point. In most networking scenarios, you will see that the factory default Fully Auto will prove the most efficient. This setting allows your ZyAIR 200 to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, ZyAIR 200 will automatically switch to a lower transmission (data) rate. Transmission at lower data speeds are usually more reliable. However, when the communication quality improves again, ZyAIR 200 will gradually increase the transmission (data) rate again until it reaches the highest available transmission rate. If you wish to balance speed versus reliability, you can select any of the above options. Fixed 11Mb/s or Fixed 5. 5Mb/s is used in a networking environment where you are certain that all wireless devices can communicate at the highest transmission (data) rate. Fixed 1Mb/s, Fixed 2Mb/s, Auto Select 1M or 2M are used often in networking environments where the range of the wireless connection is more important than speed. Preamble Type This field allows two different selections: Long and Short. Long ­ The mandatory supported "Long preamble as well as header" as specified in IEEE802. 11 that allows interoperation with the current 1Mbit/sec and 2Mbit/sec DSSS specification. Utility Setup and Configuration 4-7 ZyAIR 200 Wireleass LAN USB Adapter Short ­ The optional "Short preamble and header" is intended for applications where maximum throughput is desired and interoperability with legacy and non-short preamble capable equipment is not a consideration. RTS Threshold The RTS Threshold prevents the Hidden Node problem. [. . . ] 1-1 CTS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
