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
•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 inter-
station communication. The Access Point is required for the PC-DS.11 card to
communication to other PC-DS.11 cards or to the wired Ethernet LAN.
1.5 Where to Use DSSS
DSSS technology (Direct Sequence Spread Spectrum) spreads a signal power over
22MHz bandwidth; the same frequency is used for each transmission. This provides
the DS.11 with a fast bit rate and long range links, ideal for outdoor bridging.
