§ 2.1091 Radiofrequency radiation exposure evaluation: mobile devices.
(a) Requirements of this section are a consequence of Commission
responsibilities under the National Environmental Policy Act to evaluate the
environmental significance of its actions. See subpart I of part 1 of this
chapter, in particular § 1.1307(b).
(b) For purposes of this section, a mobile device is defined as a
transmitting device designed to be used in other than fixed locations and to
generally be used in such a way that a separation distance of at least 20
centimeters is normally maintained between the transmitter's radiating
structure(s) and the body of the user or nearby persons. In this context,
the term “fixed location” means that the device is physically secured at one
location and is not able to be easily moved to another location.
Transmitting devices designed to be used by consumers or workers that can be
easily re-located, such as wireless devices associated with a personal
computer, are considered to be mobile devices if they meet the 20 centimeter
separation requirement.
(c)(1) Mobile devices that operate in the Commercial Mobile Radio Services
pursuant to part 20 of this chapter; the Cellular Radiotelephone Service
pursuant to part 22 of this chapter; the Personal Communications Services
pursuant to part 24 of this chapter; the Satellite Communications Services
pursuant to part 25 of this chapter; the Miscellaneous Wireless
Communications Services pursuant to part 27 of this chapter; the Maritime
Services (ship earth station devices only) pursuant to part 80 of this
chapter; the Specialized Mobile Radio Service, and the 3650 MHz Wireless
Broadband Service pursuant to part 90 of this chapter; and the Citizens
Broadband Radio Service pursuant to part 96 of this chapter are subject to
routine environmental evaluation for RF exposure prior to equipment
authorization or use if:
(i) They operate at frequencies of 1.5 GHz or below and their effective
radiated power (ERP) is 1.5 watts or more, or
(ii) They operate at frequencies above 1.5 GHz and their ERP is 3 watts or
more.
(2) Unlicensed personal communications service devices, unlicensed
millimeter wave devices and unlicensed NII devices authorized under
§ § 15.253(f), 15.255(g), 15.257(g), 15.319(i), and 15.407(f) of this chapter
are also subject to routine environmental evaluation for RF exposure prior
to equipment authorization or use if their ERP is 3 watts or more or if they
meet the definition of a portable device as specified in § 2.1093(b)
requiring evaluation under the provisions of that section.
(3) All other mobile and unlicensed transmitting devices are categorically
excluded from routine environmental evaluation for RF exposure prior to
equipment authorization or use, except as specified in § § 1.1307(c) and
1.1307(d) of this chapter.
(4) Applications for equipment authorization of mobile and unlicensed
transmitting devices subject to routine environmental evaluation must
contain a statement confirming compliance with the limits specified in
paragraph (d) of this section. Technical information showing the basis for
this statement must be submitted to the Commission upon request.
(d) The limits to be used for evaluation are specified in § 1.1310 of this
chapter. All unlicensed personal communications service (PCS) devices and
unlicensed NII devices shall be subject to the limits for general
population/uncontrolled exposure.
(1) For purposes of analyzing mobile transmitting devices under the
occupational/controlled criteria specified in § 1.1310 of this chapter,
time-averaging provisions of the guidelines may be used in conjunction with
typical maximum duty factors to determine maximum likely exposure levels.
(2) Time-averaging provisions may not be used in determining typical
exposure levels for devices intended for use by consumers in general
population/uncontrolled environments as defined in § 1.1310 of this chapter.
However, “source-based” time-averaging based on an inherent property or
duty-cycle of a device is allowed. An example of this is the determination
of exposure from a device that uses digital technology such as a
time-division multiple-access (TDMA) scheme for transmission of a signal. In
general, maximum average power levels must be used to determine compliance.
(3) If appropriate, awareness of exposure from devices in this section can
be accomplished by the use of visual advisories (such as labeling,
embossing, or on an equivalent electronic display) and by providing users
with information concerning minimum separation distances from radiating
structures and proper installation of antennas.
(i) Visual advisories shall be legible and clearly visible to the user from
the exterior of the device.
(ii) Visual advisories used on devices that are subject to
occupational/controlled exposure limits must indicate that the device is for
occupational use only, must refer the user to specific information on RF
exposure, such as that provided in a user manual, and must note that the
advisory and its information is required for FCC RF exposure compliance.
Such instructional material must provide the user with information on how to
use the device in order to ensure compliance with the
occupational/controlled exposure limits.
(iii) A sample of the visual advisory, illustrating its location on the
device, and any instructional material intended to accompany the device when
marketed, shall be filed with the Commission along with the application for
equipment authorization.
(iv) For occupational devices, details of any special training requirements
pertinent to limiting RF exposure should also be submitted. Holders of
grants for mobile devices to be used in occupational settings are
encouraged, but not required, to coordinate with end-user organizations to
ensure appropriate RF safety training.
(4) In some cases, e.g., modular or desktop transmitters, the potential
conditions of use of a device may not allow easy classification of that
device as either mobile or portable (also see § 2.1093). In such cases,
applicants are responsible for determining minimum distances for compliance
for the intended use and installation of the device based on evaluation of
either specific absorption rate (SAR), field strength or power density,
whichever is most appropriate.
