Professional Installation for Model BreezeNET PRO.11/AMP1440 System
Intended use
All BreezeCOM devices are used to provide high speed data connections to remote networks.
The BreezeNET PRO.11/AMP2440 System is not intended nor is it marketed for home use. It is
designed for use by commercial businesses only.
Installation
The installation of the Model BreezeNET PRO.11/AMP2440 System will be controlled.
BreezeCOM will ensure that the professional doing the installation is made aware of the
requirements so that the final installation complies with FCC rules. Specifically the installer must
ensure that the ERP of the transmitting antenna does not exceed the requirements of paragraph
15.247(b) by using an HP 436A power meter and an HP 8481H power sensor. Power meters
that measures average power must not be used when installing the transmitter, amplifier and
antenna combination.
It will be explicitly explained to the professional installer that they will install a 250mW or 500mW
version of the amplifier based on the antenna to be used in the installation. (See attached chart).
The output power of the BreezeNET PRO.11/AMP2440 System is limited to 250mW or 500mW,
regardless of the loss of cable between the DC injector and the amplifier any length or type of 50
ohm coax transmission can be used.
Since BreezeNET PRO.11/AMP2440 System are shipped labeled as "BreezeNET
PRO.11/AMP2440-250 System" for a 250mW output and a "BreezeNET PRO.11/AMP2440-500
System" for a 500mW maximum output, the installer will be aware of the output power of the
system. Further, all installations of the Model BreezeNET PRO.11/AMP2440 System will require
topographic analysis, site survey and link budget calculation. Therefore, the system will require a
BreezeCOMed trained professional to do the installation.
This ensures compliance with the maximum transmitter ERP allowed with the antenna provided
as a system.
The following statement is in the BreezeNET user's guide (section 5.5.1) and is also supplied as
a separate sheet with each device sold:
"Professional Installers Only :
Detached antennas, whether installed indoors or out, should be installed ONLY by experienced
antenna installation professionals who are familiar with local building and safety codes and,
wherever applicable, are licensed by the appropriate government regulatory authorities. Failure to
do so may void the BreezeNET product warranty and may expose the end user to legal and
financial liabilities."
"Regulations regarding maximum antenna gains vary from country to country. It is the
responsibility of the end user to operate within the limits of these regulations and to ensure that
the professional installer is aware of these regulations, as well. "

Marketing and sales channels
BreezeCOM DOES NOT sell direct to end users. BreezeNET PRO.11/AMP2440 System will be
sold only to BreezeCOM's Authorized Resellers. Those authorized resellers are technically
trained by BreezeCOM's Engineers periodically and must follow the rules set by BreezeCOM.
The BreezeNET/AMP2440 system is designed for Long Range (10-25 miles) applications and it
involves a complicated mandatory site survey, roof top mast installation, high gain antennas,
accurate antenna alignment, etc. Those activities can be done ONLY by professional installers
that are familiar with the FCC regulations. BreezeCOM do not play in the consumer business at
all. We have no resellers in this market and we do not advertise in consumers based publications
or attend consumer oriented trade shows. The system will be advertised in technical trade shows
and magazines.
Conclusion
BreezeCOM requires professional installation for the Model BreezeNET PRO.11/AMP2440
System in-order to provide the highest reliable system possible. We therefore fully support the
mandate for professional installation of our complete system.

1.2.1. Access Point
The Access Point is fully compliant with the IEEE 802.11 wireless LAN
standard.
The BreezeNET Access Point is a wireless hub that provides access for
wireless workstations into wired Ethernet LANs. It also contains a wireless
coordinating function which enables workstations equipped with a Station
Adapter (Station Adapter, Bridge) to communicate with one another inside
the cell coverage area (even if they are not in direct line of sight) via the
Access Point. Any two wireless stations in two different cells can
communicate through their Access Points.
Disclaimer: This diagram is for
illustrative purposes only. It should
not be confused with the transceiver
operating in a standalone mode.
When this diagram is in use, the
transceiver will be used in
conjunction with amp model
AMP-2440-250/500 and the
antennas listed in this manual.
Mobile workstations, such as laptops and hand-held devices, can roam
between Access Points that belong to the same Extended Service Set (ESS).
In an Extended Service Set, all Access Points have the same ESSID. When
the access points are set up so that their coverage areas overlap, users can
roam seamlessly from cell to cell. This means that there is no interruption of
network connection when moving from one coverage area to the other
through the overlap and is completely transparent to the user and the
applications. The Station Adapters decide when a mobile user becomes
disassociated from one access point and associated with another. This
process is fully transparent, requires no user intervention and involves no
loss of data packets.
Position multiple access points in locations where heavy network traffic is
expected to create a multicell and increase the aggregate throughput
capacity in areas where it is needed most. The system implements a Load

Balancing algorithm to divide the stations equally between the available co-
located Access Points.
The BreezeNET Access Point contains an embedded SNMP agent enabling
effective management by BreezeVIEW or any standard SNMP management
station. Software upgrades can be downloaded by TFTP protocol via the
wired LAN or wireless LAN.
1.2.2. Workgroup Bridge
The BreezeNET Workgroup Bridge is a high-speed, wide-range wireless
LAN bridge that provides connectivity to remote Ethernet networks.
Figure 1.1: WB-10D PRO.11 with Two
External Antenna Connector Ports
Disclaimer: This diagram is for illustrative purposes only. It should not be
confused with the transceiver operating in a standalone mode. When this
diagram is in use, the transceiver will be used in conjunction with amp
model AMP-2440-250/500 and the antennas listed in this manual.
The Workgroup Bridge communicates with the BreezeNET Access Points of
the remote LANs effectively creating an extended wireless network
spanning sites situated up to 6 miles apart (in Europe this range is limited by
ETSI regulations to 2.5 Km.). In this way a central Ethernet LAN may be
connected with one or more branch office LANs.
In addition, an island consisting of a Workgroup Bridge together with an
Access Point can work as a relay. Transmissions from the central LAN and
from the remote LAN are relayed via the island located between them. This
configuration effectively doubles bridge range.

Introduction To The BreezeNET PRO.11 Series
BreezeNET PRO.11 Series 1-8User’s Guide
Workstations that can be connected to the wireless LAN include PCs, X-
Terminals, Digital, SUN, HP, IBM, and Apple computers, and any other
device that supports Ethernet. The unit is transparent to the workgroup
devices’ hardware, software, and network operating system.
The BreezeNET Workgroup Bridge contains an embedded SNMP agent and
software downloading capabilities enabling effective management. Software
upgrades are downloaded using TFTP protocol via the Ethernet ports or via
the wireless LAN and Access Point.
1.3. Extending Range with the AMP2440
To extend the range of the AP10-D or WB-10D, the AMP2440-250 or
AMP2440-500 is used. These devices amplify the RF output and receive
power to allow long range connections or connections with longer cable
runs. The diagram below shows a typical installation of the BreezeNet and
AMP2440. (See the addendum at the end of this manual for instructions on
how to install the AMP2440).

Introduction To The BreezeNET PRO.11 Series
BreezeNET PRO.11 Series 1-10 User’s Guide
1.5.1. 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.
1.5.2. Startup Procedure
When wireless units (other than AP-10) start up, they scan the frequencies
for an AP-10. If an active AP-10 is in range, the units synchronize with it.
The addresses associated with the units are registered in the AP-10 (the
registration process is different for each unit type). From then on, the units
can send and receive messages to and from the wired LAN.
1.5.3. AP-10 Access Point
The AP-10 Access Point is connected to a wired Ethernet LAN, and it keeps
a list of known stations on its wireless side. When an AP-10 “hears” a
message that is destined for a wireless station, the AP-10 forwards the
message wirelessly to the station. If the message has a destination address
that the AP-10 does not recognize, the AP-10 ignores the message.
The AP-10 is constantly “listening” for wireless messages as well. When the
AP-10 “hears” a wireless message destined for another wireless unit, it
relays the message directly to the wireless unit without forwarding the
message to the wired LAN. When the AP-10 “hears” a wireless message
whose destination it does not recognize (since it does not keep a list of
known stations on its wired side), it forwards the message to the wired
LAN. Messages cannot be sent directly between wireless stations without an
AP-10 to relay the message.
1.5.4. SA-10 Station Adapter
The SA-10 station adapter is connected to a station’s network card. When
the station sends a message, the SA-10 wirelessly forwards it to the AP-10.
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.

Introduction To The BreezeNET PRO.11 Series
BreezeNET PRO.11 Series 1-11 User’s Guide
1.5.5. SA-40 Station Adapter
The SA-40 station adapter has four connectors for up to four stations and
works just like the SA-10. As each station connected to the SA-40 sends its
first message, each address is registered in the AP-10. The AP-10 keeps
only up to four addresses for each SA-40, so the SA-40 will not work
properly if connected to more than four stations.
1.5.6. WB-10 Wireless Bridge
As opposed to the SA-10 and SA-40 that connect directly to stations, the
WB-10 wireless bridge connects to a wired Ethernet LAN (Hub). When a
station on the WB-10’s LAN sends a message that is not destined for a local
station, the WB-10 wirelessly forwards the message to the AP-10. And
when the AP-10 receives a message destined for a station on the WB-10s
LAN, the AP-10 wirelessly forwards it to the WB-10. In this way, the
WB-10 and AP-10 work together like a standard network bridge.
The first time each station on the WB-10’s LAN sends a message, the
station’s address is registered in the WB-10 and the AP-10. The WB-10 and
AP-10 can hold all the addresses necessary to support an entire LAN
connected to a WB-10.
