    Introduction To The BreezeNET PRO.11 Series 1.4. BreezeNET PRO.11 Functional Description BreezeNET PRO.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.
  • Page 20 Introduction To The BreezeNET PRO.11 Series And when the AP-10 receives a message destined for the station, it wirelessly forwards the message to the SA-10. The first time the station sends a message, the station’s address is registered in the AP-10. The AP-10 keeps only the first address for each SA-10, so the SA-10 will not work properly if connected to more than one station.

Antennas for Outdoor Applications can be used in point-to-point or point-to- BreezeNET PRO.11 Series multipoint configurations. 5.3.3.1 Point-to-Point A point-to-point link is based on the use of one Access Point with external antennas (AP-10D or AP-10DE) and one adapter (SA-10/40D, WB-10D or WB-10DE).
  • Page 96 In applications where no multipath propagation is expected, a single antenna is sufficient to ensure good performance levels. However, in cases where multipath propagation exists, BreezeCOM recommends that two antennas be used. This takes advantage of space diversity capabilities. By using two antennas per unit, the system can select the best antenna on a per-packet basis (every several milliseconds).
