2 This device must accept any interference received, including interference that
may cause undesired operation.
FCC Radio Frequency Interference Statement
The Subscriber Unit equipment has been tested and found to comply with the
limits for a class B digital device, pursuant to part 15 of the FCC rules and to
ETSI EN 301 489-1 rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a
residential environment notwithstanding use in commercial, business and
industrial environments. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
The Base Station equipment has been tested and found to comply with the limits
for a class A digital device, pursuant to part 15 of the FCC rules and to EN 301
489-1 rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in commercial, business
and industrial environments. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at
the user’s own expense.
FCC Radiation Hazard Warning
To comply with FCC RF exposure requirement, the antenna used for this
transmitter must be fixed-mounted on outdoor permanent structures with a
separation distance of at least 2 meter from al persons for antennas with a gain
up to 27 dBi, and must not be co-located or operating in conjunction with any
other antenna or transmitter.
R&TTE Compliance Statement
This equipment complies with the appropriate essential requirements of Article 3
of the R&TTE Directive 1999/5/EC.
Safety Considerations

Caution
To avoid electrical shock, do not perform any servicing unless you are qualified to
do so.
Line Voltage
Before connecting this instrument to the power line, make sure that the voltage of
the power source matches the requirements of the instrument.
Radio
The instrument transmits radio energy during normal operation. To avoid
possible harmful exposure to this energy, do not stand or work for extended
periods of time in front of its antenna. The long-term characteristics or the
possible physiological effects of Radio Frequency Electromagnetic fields have not
been yet fully investigated.
Outdoor Unit and Antenna Installation and Grounding
Ensure that outdoor units, antennas and supporting structures are properly
installed to eliminate any physical hazard to either people or property. Make sure
that the installation of the outdoor unit, antenna and cables is performed in
accordance with all relevant national and local building and safety codes. Even
where grounding is not mandatory according to applicable regulation and
national codes, it is highly recommended to ensure that the outdoor unit and the
antenna mast (when using external antenna) are grounded and suitable lightning
protection devices are used so as to provide protection against voltage surges and
static charges. In any event, Alvarion is not liable for any injury, damage or
regulation violations associated with or caused by installation, grounding or
lightning protection.
Disposal of Electronic and Electrical Waste

Chapter 1 - System Description
1.1 Introducing BreezeACCESS 4900
BreezeACCESS 4900 is a high capacity, IP services oriented Broadband Wireless
Access system operating in the 4.9 GHz licensed spectrum band allocated for
public safety. The system employs wireless packet switched data technology to
support high-speed IP services with a network connection that is always on. The
system is designed for both Point-to-Point and Point-to Multipoint configurations,
supporting data, VoIP and video applications.
The system supports Virtual LANs based on IEEE 802.1Q, enabling secure
operation and Virtual Private Network (VPN) services. The system supports layer-
2 traffic prioritization based on IEEE 802.1p and layer-3 traffic prioritization
based on either IP ToS Precedence (RFC791) or DSCP (RFC2474). It also supports
traffic prioritization based on UDP and/or TCP port ranges. BreezeACCESS 4900
uses advanced security mechanisms, including WEP128, AES128 and FIPS 197
compliant encryption algorithms.
Using OFDM modem technology and high power radios, BreezeACCESS 4900
offers an unmatched combination of wide coverage, high capacity and value-
added features to provide wireless connectivity that works also in near and
non-line-of-site (NLOS) conditions.
Alvarion’s Complete Spectrum solution enables the BreezeACCESS 4900 to
integrate seamlessly into other BreezeACCESS networks. Supporting both fixed
and mobile platforms at multiple frequency bands, the Complete Spectrum
enables simultaneous deployment of systems at 900 MHz, 2.4 GHz, 3.5 GHz,
4.9 GHz, and the entire 5 GHz band.
A BreezeACCESS 4900 system comprises the following:
 Customer Premise Equipment (CPE): BreezeACCESS 4900 Subscriber Units
(SUs).
 Base Station Equipment (BS): BreezeACCESS 4900 Access Units and
supporting equipment.
 Networking Equipment: Standard Switches/Routers supporting connections
to the backbone and/or Internet.
 Management Systems: SNMP-based Management, Billing and Customer
Care, and other Operation Support Systems.
