1.3 RF ENERGY EXPOSURE INFORMATION FOR FIXED OPERATION

1.3.1 Maximum Permissible Exposure Limits

DO NOT TRANSMIT with this Client and antenna when persons are within the MAXIMUM
PERMISSIBLE EXPOSURE (MPE) Radius of the antenna. The MPE Radius is the minimum distance
from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than the
allowable MPE level set by the FCC.

EXPOSURE (MPE) LIMIT. IT IS THE RESPONSIBILITY OF THE STATION
LICENSEE TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPOSURE

TRANSMISSION. THE STATION LICENSEE IS TO ENSURE THAT NO
BYSTANDERS ARE WITHIN THE RADIUS LIMITS.

1.3.2 Determining MPE Radius

THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS is unique for each site and is determined
based on the complete installation environment (i.e., co-location, antenna type, transmit power level, etc.).
Determination of the MPE distance is the responsibility of the VIDA Broadband user. Calculation of the
MPE radius is required as part of the installatio n. The limit for Uncontrolle d Exposure Power Density

) is 10 W/m2 for fixed mounted device.

(P

d

The Harris 4.9 GHz VIDA Broadband Client may be installed as a fix ed mounted radio. After installation
and commissioning, the safe distance from the 9 dBi omnidirectional antenna is greater than 20 cm
(8-inches).

1.3.2.1 MPE Calculation for Omnidirectional Antenna

This MPE Minimum Distance Calculation is based on using a 9 dBi gain omnidirectional antenna
mounted directly to the Client RF port.

Basic Harris 4.9 GHz VIDA Broadband Client specifications:

P: Maximum Peak Conducted Power = 30 dBm
G: Maximum Omni Antenna Gain = 9 dBi

Frequency Range = 4.90 to 4.99 GHz

R: Minimum Distance between User and Antenna = 0.3 m

Equation from FCC:

Pd = P * GN / ( 4 * π * Rmin 2 )
P

= 1 W * 7.94 / (4 * 3.1415926 * 0.3 2) = 7.0 W / m2 < 10 W / m

d

The calculation indicates that the minimum 0.3 meter distance between user and the omnidirectional
antenna (directly mounted to the Client RF port) is required when operating the Harris 4.9 GHz VIDA
Broadband Client.

1.3.2.2 MPE Calculation for Directional Antenna

This MPE Minimum Distance Calculation is based on using a directional antenna with more than 9 dBi
antenna gain.

Basic Harris 4.9 GHz VIDA Broadband Client specifications:

P: Maximum Peak Co nducted Power = 30 dBm
G: Maximum Omni Antenna Gain – Cable Loss = 27 dBi – 1 dB = 26 dBi; (Use numerical G

for the calculation ): G

= 10 ^ (G /10); For G = 26 dBi, GN = 10 ^ (26 /10) = 398

When licensed by the FCC, this Client complies with the FCC RF exposure limits when persons are
beyond the MPE radius of the antenna. In addition, your Harris VIDA Broadband Client installation
complies with the following Standards and Guidelines with regard to RF energy and electromagnetic
energy levels and evaluation of such levels for exposure to humans:

FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines
for Human Exposure to Radio Frequency Electromagnetic Fields.

American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety Levels with
Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.

American National Standards Institute (C95.3 – 1992), IEEE Recommended Practice for the
Measurement of Potentially Hazardous Electromagnetic Fields – RF and Microwave.

To ensure that your exposure to RF electromagnetic energy is within the FCC
allowable limits for occupational use, do not operate the station in a manner that
would create an MPE distance in excess of t hat allowable by the FCC.

1.4 RF ENERGY EXPOSURE INFORMATION FOR MOBILE OPERATION

The FCC requires licensees and manufacturers to meet radio frequency radiation exposure compliance as
defined by FCC rule 47 CFR §2.1091 and as discussed in FCC document OET Bulletin 65: Evaluating
Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields.

Page 5 of OET Bulletin 65, Supplement C, subtitled: Mobile Devices states the following:

“The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091.
For purposes of RF exposure evaluation, a mobile device is defined as a transmitting device
designed to be used in other than fixed locations and to be generally used in such a way that a
separation distance of at least 20 centimeters is normally maintained between the transmitter's
radiating structures and the body of the user or nearby persons.”

Page 7 of OET Bulletin 65, Section 2, subtitled: Guidelines for evaluating Mobile and Portable Devices
states the following:

“Mobile devices identified in 47 CFR §2.1091 that operate at 1.5 GHz or below with an effective
radiated power (ERP) of 1.5 watts or more, or those that operate at frequencies above 1.5 GHz
with an ERP of 3.0 watts or more are required to perform routine environmental evaluation for RF
exposure prior to equipment authorization or use; otherwise, they are categoricall y excluded.”

The 4.9 GHz Broadband Client radio with 0.5 Watt RF output, installed as a mobile device using the 5.5
dBi mobile antenna and cable mounts referenced in Table 1-2 has a calculated worst case ERP of 1.78
Watts relative to an isotropic radiator (EIRP). Therefore, it can be concluded that a 4.9 GHz Client radio
installed as a mobile device using the Harris recommended mobile antenna system is categorically
excluded from any requirement to perform routine environmental evaluation for RF exposure. This is
true with other mobile antenna systems having gains up to 7.7 dBi.

Changes or modifications not expressly approved by Harris Corporation could void
the user's authority to operate the equip men t and may require the user to perform
routine environmental evaluation of the mobile installation.

This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distan ce. It uses RF energy or radio waves to send
and receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not
limited to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these
other forms of electromagnetic energy, which, when used improperly , can caus e bi olo g ical d amage. Very
high levels of x-rays, for example, can damage tissues and genetic material.

Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for exposure to RF energy. These standards provide recommended levels of RF exposure for
both workers and the general public. These recommended RF exposure l evels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government established RF exposure levels. In addition, manufacturers also
recommend specific operating in structions to users of two-way radios. These instru ctions are important
because they inform users about RF energy exposure and provide simple procedures on how to control it.
Please refer to the following websites for more information on what RF energy exposure is and how to
control your exposure to assure compliance with established RF exposure limits.
