1.3 BreezNET DS.11 Compatibility and Standards

• IEEE 802.11 TGb Compliant – All BreezeNET DS.11 series units are fully

compliant with the final IEEE 802.11 specification for wireless LANs, and
thus support interoperability with other 802.11 compliant vendors.

• Completely inter-operable with other 802.11 and 802.11 TGb products

• Supports the common SNMP standard MIB groups and the 802.11 MIB

• Uses the 2.4 Ghz ISM unlicensed band

1.4 BreezeNET DS.11 Functional Description

BreezeNET DS.11 units add wireless functionality to existing Ethernet LANs.

1.4.1 Quick Review of Ethernet

Standard Ethernet LAN stations are wired to a common bus. When one of the
stations sends a message, it assigns a destination address to the message and sends
the message on the bus. All stations on the bus “hear” the message, but only the
station with the proper address processes the message.

1.4.2 AP-DS.11 Wireless Access Point

The AP-DS.11 enables 802.11 access to 802.3 (Ethernet) and guarantees inter­station communication.

1.4.3 SA-DS.11 Wireless Station Adapter

The SA-DS.11 station adapter connects up to 4 workstations through a hub. When a
station on the SA-DS.11’s LAN sends a message that is not destined for a local
station, the SA-DS.11 wirelessly forwards the message to the AP-DS.11. When the
AP-DS.11 receives a message destined for a station on the SA-DS.11's LAN, the
AP-DS.11 wirelessly forwards it to the SA-DS.11. In this manner, the SA-DS.11
and the AP-DS.11 work together like a standard network bridge.
