Limits for Human Exposure to Radio Frequency Emissions.” Both of these documents are available via the
Internet at the OET web site:
The Enfora Enabler-G products are GSM radio transceivers, which operate under the authority of 47 CFR
Part 24, Subpart E of the FCC Rules and Regulations. When installed and operated in accordance with the
instructions provided in this manual, these devices comply with current FCC regulations regarding human
exposure to radio frequency radiation.
The following installation and operation restrictions apply to all Enfora Enabler-G products:
•
This device may only be used in fixed and mobile applications.
•
Portable applications, as defined by the FCC, are prohibited.
•
The use of this device for desktop and other applications where the antenna can easily be
relocated are considered by the FCC to be mobile applications.
•
A separation distance of at least 20 cm (7.87 inches) between the antenna and the body
of the user and other persons must be maintained at all times
•
In FIXED applications,
antenna gain
is limited to a maximum of 7 dBi, with a
corresponding Equivalent Isotropic Radiated Power (EIRP) of 37 dBm / 5 W.
•
In MOBILE applications,
antenna gain
is limited to a maximum of 3 dBi, with a
corresponding EIRP of 33 dBm / 2 W.
•
End products must provide instructions to ensure compliance with radio frequency
radiation exposure requirements.
•
A warning label visible to all persons exposed to the antenna and identical to that
described in this manual must be displayed on or next to the antenna.
•
Separate FCC approval for RF exposure compliance is required for end products that do
not meet these conditions.
Antenna gain is defined as gain in dBi (dB referenced to an isotropic radiator) minus cabling loss.
Note:
Additional care must be taken by the installer and/or user of the Enfora Enabler-G products to ensure
proper antenna selection and installation. Adherence to the above conditions is necessary to comply with
FCC requirements for safe operation regarding exposure to RF radiation.
Depending upon the application and type of product into which the Enfora Enabler-G module has been
incorporated, specific OEM actions and responsibilities required to meet these conditions vary. However, in
all cases the primary concern is to ensure compliance with current FCC guidelines and regulations that limit
human exposure to radio frequency radiation.
Definitions
For the purpose of determining compliance with current FCC rules addressing human exposure to
radio frequency radiation, the FCC has established the following three categories of transmitting
devices:
•
Portable Devices – devices where the antenna is located within 20 cm (7.87 inches) of
any person, including the user, if applicable. Portable devices operating under the
authority of Part 24 (broadband PCS) are limited to a maximum of 2 W EIRP.
•
Mobile Devices – devices designed to be used in other than fixed locations and generally
such that the antenna is located at a minimum of 20 cm (7.87 inches) from any person,
including the user, if applicable. Mobile devices operating under the authority of Part 24
(broadband PCS) are limited to a maximum of 2 W EIRP.
