FOOTNOTES
See RM-5l93 on video transmittersin the 902-928 MHz band,
RM-5250 regarding improvement in the AM broadcasting service,
and RM-5575 concerning TV interface devices.
2 The limit applied to these early devices was 15
microvolts/meter (uV/m) at a distance equivalent to the
wavelength of the operating frequency divided by 2 Pi. This limit
is currently shown in Section 15.7.
The Commission is tasked under Sections 302 and 303 of the
CommunicationsAct of 1934, as amended, to establish regulations
necessary to prevent harmful interference to the authorized radio
services.
The Commission has traditionaltyattempted to keep emissions
from all Part 15 devices to the minimum level necessary for
operation. Furthermore, the Commission has expressed its desire
to minimize the level of interference received by the authorized
radio services. See , for example, "Report on the Status of the
AM Broadcast Rules". Federal Communications Commission,
April 3, 1986.
in most instances, we propose a period of ten years for devices
to come into compliance with the new 5tandards. We believe that
this should provide sufficient time to redesign equipment within
manufacturers' normal redesign
6 Another category of devices addressed under Part 15 is in-
cidental radiators. These are devices that do not intentionally
incorporate the generation of radio frequency energy in their
design but generate RF energy as a by-product of their operation,
Examples include electric motors, light dinirners, and certain
home appliances. in this proceeding, we are not proposing any
standards for such devices with the exception that these devices
operate on a non-interferencebasis.
See 47 CFR 15.4(f), (j), (k), (1).
8See 47 CFR 15.4(n).
tSce 47 CFR 15.61
The energy conducted back into the power line can radiate
from the power line. This type of interference usually occurs in
the spectrum below 30 MHz. Limits on the amount of RF energy
conducted back into the power line protects services such as AM
broadcasting, amateur radio, and public safety.
' The dividing line between the 1000 uV and 3000 uV con-
ducted limits is proposed to be changed from 1.6 MHz to 1.705
MHz to reflect the projected expansion of the AM broadcasting
service.
12 The proposals contained in the paragraphs concerning the
"Detector Functions of Measuring Instruments" as well as the
proposed regulations concerning "Measurement procedures" and
"Emission limits" will affect these proposed field strength limits.
13 See "Technical Subcommittee (TSC) Review of The Federal
Communications Commission's Draft Notice of Proposed Rule
Making in the matter of Revision of Parts 2 and 15 of the Rules
Regarding the Operation of Non-Licensed Radio Frequency De-
vices", National Telecommunications and Information Ad minis-
tration, U. S. Department of Commerce. November 5, 1986. It
should be noted that this report recommends lower emission
limits in the frequency bands below 960 MHz than the limits
proposed in this Notice. A copy of this report will be placed in
the docket file for this proceeding.
14 Under the current regulations, restricted bands apply to
control and security alarm devices operating under the provisions
of Sections 15.181-15.187 and 15.201-15.215 of the regulations, 47
CFR 15.181-15.187, 15.201-15.215. As these regulations are the
only ones that permit large numbers of consumer devices within
the frequency bands allocated to the U.S. Government without
control as to the exact frequency location, it was necessary to
restrict the operating frequencies in order to avoid interference to
certain sensitive Operations.
See the reference in footnote 13. The NTIA report recom-
mends lower emission limits in the restricted bands than those
proposed in this Notice.
Under Sections 302 and 303 of thc Communications Act of
1934, as amended, the Commission is tasked to establish regula-
tions necessary to prevent harmful interference to the authorized
radio services. In order to carry out this obligation, the Commis-
sion has attempted to keep emissions from all Part 15 devices to
the minimum level practicable or necessary for operation.
17 These limits are identical to the field strength limits proposed
for intentional radiators above 30 MHz. We see no justification as
to why unintentional radiators, primarily receivers, should be
allowed to continue to operate at a higher field strength limit
than what is proposed for intentional radiators, especially since
unintentional radiators tend to be left on, and emitting radio
frequency signals, for longer periods of time than intentional
radiators.
18 See 47 CFR. 15.59. CB receivers employing antenna terminals
are required to meet a conducted limit at those terminals of 0.2
nW.
19 Presently, Subpart C of Part 15 specifies emission limits only
for CB receivers and receivers that operate (tune) within the
frequency ranges of 30-901 MHz and 935-940 MHz.
20 Home satellite receivers usually downconvere the received
frequency to an intermediate frequency above 900 MHz. The
increasing popularity of such receivers has caused a rapid increase
in their proliferation, thereby increasing their potential for caus-
ing interference, particularly to the aeronautical radionavigation
services.
21 On May 13, 1987, the Commission released a Public Notice
deleting the requirement to file FCC Form 740 for musical greet-
ing cards, quartz watches and clocks, modules of quartz watches
and clocks, and battery powered hand-held calculators and elec-
tronic games not requiring connection to the AC power lines.
This Notice proposes to detail these exemptions in the regula-
tions.
22 See Order Granting Lintited Waiper, adopted April 23, 1985,
released April 26, 1985, FCC 85-204, in response to RM-4840.

2 FCC Red Vol. 20
- The frequency range over which receivers are subject
to the technical standards and equipment authorization
procedures would be expanded to include the frequency
bands of 901 to 935 MHz and 940 to 1000 MHz
- The conducted signal limits, except for the limit on the
antenna transfer switch and emissions conducted on the
power lines, for a TV interface device would be deleted
- The inclusion of video distribution systems and cable
terminal devices under the same standards as applied to
TV interface devices would be clarified.
Intentional Radiators:
A power line conducted limit of 250 microvolts in the
frequency range of 450 kHz to 30 MHz is proposed for all
devices except carrier current systems operating in that
frequency band
- With certain exceptions, antennas would be either
permanently attached or use a unique coupler
- Spurious emissions would be measured to the higher
of either the 10th harmonic or the range specified for
unintentional radiators
- General emission limits are proposed to be established
at which any form of operation is permitted on almost any
frequency - these limits are equivalent to the Class B
digital device limits above 30 MHz, the existing limits
below 1.705 MHz, and new limits between 1.705 and 10
MHz and above 960 MHz
- Restricted bands related to safety-of-life and sensitive
authorized services, e.g., radio astronomy and satellite
down links, are proposed within which only spurious
emissions are permitted
- The existing Part 15 frequency "windows" within
which higher field strength limits are permitted would be
retained
- External input signals on cordless telephones would be
permitted
- The requirement to use a microphone to directly
modulate a transmitter in the 88 to 108 MH band would
be deleted and these transmitters would be subject to
certification
- A tunnel radio system is proposed to be established to
permit any form of operation within a tunnel or mine
without limiting the level of emissions within that tunnel
or mine
- Campus radio AM broadcast systems would be recog-
nized
- General use, higher field strength bands without chan-
nelization or bandwidth restrictions are proposed to be
established on the following frequency bands:
13.553-13.567 MHz. 26.96-27.28 MHz, 40.66-40.70 MHz,
49.82-49.90 MHz, 902-928 MHz, 2400-2483.5 MHz,
5725-5875 MHz, and 24.0-24.25 0Hz
- Specific regulations for devices that measure the char-
acteristics of a material (except for the 890-940 MHz
band) and some telemetering devices would be deleted to
be replaced by the general limits, the general use, higher
field strength bands, or other frequency bands designed in
the item
- Comments are requested on the feasibility of applying
field strength limits to the currently permitted frequency
hopping and direct sequence spread spectrum systems in-
stead of the present limit on output power
- Automated vehicle identification systems operating in
the 2.9 to 4.1 0Hz band would be deleted
- The existing channelized operations at 27 MHz and 49
MHz would be phased-out in favor of the general use
bands, and the spurious emission limits for cordless tele-
phones, as well as for general operation in the 27 MHz
and 49 MHz bands, would be tightened over a grandfather
period
- Peak emissions from periodic transmitters operating
above 70 MHz. including control and security alarm de-
vices, would be limited to 20 dB above the permitted
average field strength limits.

Under the proposed regulations, all intentional radiators, except carrier Current systems operating from 450 kHz to 30
MHz, must limit their conducted emissions to 250 uV within the frequency range of 450 kHz to 30 MHz (see proposed
15.207). Unless otherwise stated, spurious emissions must be attenuated to the limits shown in the proposed Section 15.209.
In addition, the range of frequencies over which spurious and harmonic emissions are investigated is proposed to be
increased for some intentional radiators (see proposed 15.33). Further, there are a number of frequency bands on which
operation is not permitted (see proposed 15.205).

Numerous bands above 40 GHz should be restricted because of use in radio
astronomy, satellite down links, etc. However, the state-of-the-art in measure-
ment techniques generally limits measurement range to 40 GHz. Due to this lack
of ability to perform measurements above 40 0Hz and the present lack of
consumer demand for operation above this frequency, operation of a Part 15
device on frequencies higher than 40 0Hz is not proposed at this time.
