Sec. 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 Sec. 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) Mobile devices that operate in the Cellular Radiotelephone Service, the
Personal Communications Services, the Satellite Communications Services, the
General Wireless Communications Service, the Wireless Communications
Service, the Maritime Services and the Specialized Mobile Radio Service
authorized under subpart H of part 22 of this chapter, parts 24, 25, 26 and
27 of this chapter, part 80 of this chapter (ship earth stations devices
only) and part 90 of this chapter are subject to routine environmental
evaluation for RF exposure prior to equipment authorization or use if they
operate at frequencies of 1.5 GHz or below and their effective radiated
power (ERP) is 1.5 watts or more, or if they operate at frequencies above
1.5 GHz and their ERP is 3 watts or more. Unlicensed personal communications
service devices, unlicensed millimeter wave devices and unlicensed NII
devices authorized under Sec. Sec. 15.253, 15.255, and 15.257, and subparts D and E
of part 15 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 Sec. 2.1093(b) requiring evaluation under the provisions of that
section. 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 Sec. Sec. 1.1307(c)
and 1.1307(d) of this chapter. 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 as part of their application.
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 Sec. 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 Sec. 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 Sec. 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, compliance with exposure guidelines for devices in this
section can be accomplished by the use of warning labels and by providing
users with information concerning minimum separation distances from
transmitting structures and proper installation of antennas.
(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 Sec. 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.
