WaveNetLinkAXInstallationandOperationsManual
Welcome!
Welcome to the Wireless, Inc. WaveNet Link™Series product family. This manual is designed
to introduce you to the Link AX™, and to provide you with information necessary to plan, install,
operate and maintain a Link AX wireless communication system.
The Link AX is intended for professional installation only. This manual, however, is also
designed for personnel who plan, operate and administrate the Link AX communication system.
Please review the entire manual before powering up or deploying any Link AX.
Updates to this manual will be posted on the Wireless, Inc. Customer Service Website at
http://www.wire-less-inc.com . Registered Wireless customers can access Wireless’on-line
information and support service, available 24 hours a day, 7 days a week. Our on-line service
provides users with a wealth of up-to-date information, with documents being added or updated
each month.
Radiation Warnings
Microwave Radio Radiation Warning
Under normal operating conditions, Link AX radio equipment complies with the limits for human
exposure to radio frequency (RF) fields adopted by the Federal Communications Commission
(FCC). All Wireless, Inc. microwave radio equipment is designed so that under normal working
conditions, microwave radiation directly from the radio is negligible when compared with the
permissible limit of continuous daily exposure recommended in the United States by ANSI/IEEE
C95.1-1991 (R1997), Safety Levels with Respect to Human Exposure to Radio Frequency
Electromagnetic Fields, 3 kHz to 300 GHz.
Microwave signal levels that give rise to hazardous radiation levels can exist within transmitter
power amplifiers, associated RF multiplexers, and antenna systems.
Never look into the open end of a Waveguide as eyes are particularly vulnerable to radiation.
Do not disconnect RF coaxial connectors, open microwave units, or break down any
microwave screening while the radio equipment is operating.

WaveNetLinkAXInstallationandOperationsManual
Microwave Antenna Radiation Warning
Designed for point-to-point operation, a Link AX microwave radio system uses directional
antennas to transmit and receive microwave signals. These directional antennas are usually
circular or rectangular in shape, and are usually mounted outdoors on a tower or mast, well
above ground level.
Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal Communication
Commission’s Office of Engineering & Technology, limits for maximum permissible exposure
(MPE) to microwave signals have been adopted by the FCC for General Population/Uncon-
trolled environments. This limit is 1.0 mW/cm2, with averaging times of thirty-minutes.
The closer you are to the front center-point of a microwave antenna, the greater the power
density of its transmitted microwave signal. Unless you are very close, however, microwave
exposure levels will fall far below the MPE limits. To determine how close to a microwave
antenna you can be and still remain below the MPE limits noted above, “worst case”predictions
of the field strength and power density levels in the vicinity of an Link AX™microwave antenna
can be made from the following calculations. The equation is generally accurate in the far-field
of an antenna, and will over-predict power density in the near-field (i.e. close to the antenna).
S = PG/4πR2
where: S = power density (in mW/cm2)
P = power input to the antenna (mW)
G = power gain of the antenna in the direction of interest relative to an isotropic
radiator
R = distance to the center of radiation of the antenna (cm)
Note that G, the power gain factor, is usually expressed in logarithmic terms (i.e., dB), and must
be converted using the following equation:
G = 10 dB/10
For example, a logarithmic power gain of 17.5 dB is equal to a numeric gain of 56.23.
Assuming (1) maximum output power from the Link AX (+12 dBm [15.8 mW]), (2) no signal loss
in the cable connecting the Link AX to the antenna, and (3) the use of a 17.5 dBi gain flat panel
antenna, the 1.0 mW/cm2MPE power density limit would be reached at a distance of
approximately 8.4 cm. The Link AX is classified as a fixed installation product, and per FCC
policy guidelines regarding MPE, antennas used for this Wireless Inc. transmitter must be
installed to provide a separation distance of 2 meters (6 feet) or more from all persons during
normal operation to satisfy FCC RF exposure compliance.
Wireless, Inc. fully supports the FCC’s adopted MPE limits, and recommends that personnel
maintain appropriate distances from the front of all directional microwave antennas. Should you
have questions about Link AX microwave signal radiation, please contact the Wireless, Inc.
Customer Service Department.

WaveNetLinkAXInstallationandOperationsManual
Point-to-Point Radio Operation
The Link AX microwave radio system is intended for point-to-point, line-of-sight applications
only. The antennas utilized in these applications are high gain, highly directive antennas, and
are intended for professional installation. Antennas should be mounted on permanent struc-
tures such as masts or towers, which are not accessible to the general public.
The installer shall mount the antennas as to comply with the limits for human exposure to radio
frequency (RF) fields per paragraph 1.1307 of the Federal Communication Commission (FCC)
Regulations. The FCC requirements incorporate limits for Maximum Permissable Exposure
(MPE) in terms of electric field strength, magnetic field strength, and power density.
It is the responsibility of the installer to ensure the antennas are used with the Link AX radio,
are designed for fixed point-to-point operations, and their use with the radio complies with FCC
limits stated in Part 15.407.
The following information is supplied pursuant to FCC Regulations (Part 15.407) for unlicensed
intentional radiators:
The Link AX conforms to the regulations in CFR 47, Part 15.407 pertaining to unlicensed point-
to-point use. Modifications to the equipment, which would alter the conditions of the Equipment
Grant of Authorization are strictly prohibited, and may void the user’s right to operate the
equipment.
Notice Regarding Operation pursuant to FCC part 15 Rules
This 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. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. 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 his own expense.

Table 1.1 - FCC U-NII Bands
1.3 Regulatory Information
In January 1997, the FCC made available 300 MHz of spectrum for Unlicensed National
Information Infrastructure (U-NII) devices. The FCC believes that the creation of the U-NII band
will stimulate the development of new unlicensed digital products which will provide efficient
and less expensive solutions for local access applications.
The U-NII band is divided into three sub bands at 5.15 - 5.25, 5.25 - 5.35 and 5.725 - 5.825 GHz.
The first band is strictly allocated for indoor use and is consistent with the European High
Performance Local Area Network (HIPERLAN). The second and third bands are intended for
high speed digital local access products for “campus”and “short haul”microwave applications.
