11Certification
- Used for most Equipment Authorizations Formerly
called Type Acceptance. - Is more than just a test report actually a
legal document - Requires a detailed list of Exhibits
- See 2.1033 for complete detail
- Test Report should be designed to show
transmitter is well-behaved
12Licensed Radio Services Test Parameters
- 2.1046 - Power Output
- 2.1047 - Modulation Characteristics
- 2.1049 - Occupied Bandwidth
- 2.1051 - Antenna Terminal Spurious Emissions
- 2.1053 - Radiated Spurious Emissions
- 2.1055 - Frequency Stability for Temperature and
Voltage Variations
13Licensed Radio Services Test Parameters
- In most cases - the actual Radio Service rules
have special or unique requirements and
additional testing parameters.
14Licensed Radio Services Test Parameters
- In addition to the Part 2 rules addressing test
parameters the FCC also recognizes the test
methods contained in ANSI/TIA/EIA-603-1992
document - Reference test procedures in report
15Licensed Radio Services Test Parameters
- Remember that the purpose of performing the
measurements required and submitting
interpretations is to establish compliance with
the technical requirement contained in the Radio
Service Rules.
16Licensed Radio Services Test Parameters
- Power Output 2.1046
- For any special case as sighted in the specific
rules compliance to 2.1046 test method is
accepted provided the specific Rule is addressed
as part of the information.
17Licensed Radio Services Test Parameters
- Where sections of the recommended standard
EIA-603 differ from Part 2 requirements - the
Part 2 test method must be used for testing
purposes.
18Licensed Radio Services Test Parameters
- Modulation Characteristics 2.1047
- Test requirements of this section differ from
EIA-603 requirements. - Compliance to Part 2 requirements is mandatory.
19Licensed Radio Services Test Parameters
- Example EIA 603 differs from Part 2.1047
regarding the range which the audio frequency
response is to be measured. - Part 2.1047 requirement of 100 - 5000 Hz should
be used for this test. - General Test Setup
20Licensed Radio Services Test Parameters
- Occupied Bandwidth 2.1049
- While this test is identified as Occupied
Bandwidth which is defined as that portion where
99 of the emitted energy (with the remaining
0.5 above 0.5 below the occupied band), the
results are mainly used to compare modulated
spectrum with emissions masks - OBW _at_ 10 Log (0.01) -20 dBc
- Other rule sections may call out -23 or -26 dBc
21Licensed Radio Services Test Parameters
- In addition to meeting the emission mask, the
occupied bandwidth may not exceed the authorized
bandwidth as listed in the Radio Service Rules. - This test should be performed for each kind of
emission to be listed on the FCC Grant. - Note the emission mask is normally applied with
0 dB equal to the level of the unmodulated
carrier.
22Emissions Mask ExampleAnalog Modulation
Mask
23Emissions Mask ExampleDigital Modulation
24Licensed Radio Services Test Parameters
- 2.1049 does not cover Occupied Bandwidth tests
for amplifiers or similar units since these
devices are intended to reproduce the modulated
signal. - Amplifiers designed to handle multiple channels
should be tested with multiple channels for each
emission to show intermodulation products. - Tests for power amplifiers still should include
gozinto and gozouta plots for each modulation
desired.
25Licensed Radio Services Test Parameters
- Intermodulation is considered a spurious emission
by the FCC and are covered by the general
emission limitations (masks) in each radio
service. - This specifically refers to the IM products
produced by transmitters / amplifiers carrying
two or more signals.
26Licensed Radio Services Test Parameters
- Antenna Terminal Spurious Emissions 2.1051
- (Otherwise know as Conducted Emissions)
- View levels of harmonic emissions.
- An extension of the occupied bandwidth test
showing the emission up to the highest frequency
as specified in Section 2.1057 usually 10th
harmonic.
0
27Licensed Radio Services Test Parameters
- If the unit does not have a detachable antenna or
an antenna output terminal then the test data is
collected at the base of the antenna.
28Licensed Radio Services Test Parameters
- Field Strength of Spurious Emissions 2.1053
- ERP/EIRP Spurious Measurement
- This test includes those emissions radiated from
the cabinet, chassis, and associated wiring. The
specification is the same emission mask under the
Radio Service rules extended to the highest
frequency specified in 2.1057. - Substitution method described in TIA/EIA 603
required test procedure. Be sure to account for
SWR when using broadband antennas !
29Licensed Radio Services Test Parameters
- Frequency Stability 2.1055
- Done over temperature -30 C to 50 C and
operating voltage /- 15 specifications. - Battery operated devices should also include
B.E.P Battery End Point - Usually defined in ppm but other units such as
Hz, are accepted as defined in specific rule
section. - Differs some from methodology described in
- TIA/EIA 603
30Licensed Radio Services Test Parameters
- Reference Standards
- TIA/EIA 603 Land Mobile FM or PM Communications

Recent FCC Clarifications, Latest NPRMs and
Rules Changes
45Presentation Overview
- Part 15 Recent Interpretation Issues, Reminders,
and Application Concerns - Part 15 Rulemaking updates
- NPRMs, Report and Orders, etc.
46Multiple Modulation Capabilities in One Device
- One familiar example, 802.11(g) incorporates the
following modulation capabilities. - BPSK modulation at 1 and 2 Mb/s
- CCK modulation at 5.5 and 11 Mb/s
- OFDM modulation at 54 Mb/s
- The FCC expects each of these modes and
- modulations to be evaluated (i.e. pretest, etc.)
47Multiple Modulation Capabilities in One Device
Cont.
- Justification for worse case results reported or
modes reported should be included in the test
report - As a minimum, it is suggested that an 802.11g
test report should include - Data for BPSK/CCK. Due to similar
- waveforms, only worse case data needs
- to be shown for these 2 modulations
- Data for OFDM
48AC Line Conducted Emissions for Part 15 Modules
- Section 15.207(a) requires test data unless the
device is battery powered with no provision for
receiving power directly or indirectly from an AC
source. - Any application granted for battery power only
will be listed as a condition on the grant
of authorization.
49AC Line Conducted Emissions for Part 15 Modules
Cont.
- Battery powered examples
- The transmitter is powered by an on-board
battery. - Transmitter has a battery connector/compartment
- The transmitter is only intended for battery
powered applications and installed by OEM. - Device is conditioned only for battery powered
applications and a limited module approval is
issued - Any new non-battery application requires a new
authorization (new FCC ID) - The transmitter is installed only in the
manufacturers equipment that will be
battery powered - Grant is conditioned accordingly and a LMA is
issued
50CISPR AC Line Conducted Limits for All
Transmitters
- Since December 3, 2002, all Part 15 and 18
devices required to be tested for AC Line
conducted emmissions must have either Note Code
05 or CE listed on the grant of equipment
authorization.
51CISPR AC Line Conducted Limits for All
Transmitters Cont.
- "05" NOTE- The manufacture and importation of
this device must cease on July 10, 2005 pursuant
to 15.37(j) or 18.123 transition provisions
adopted under FCC 02-157 (ET Docket 98-80). - "CE" NOTE - This device has shown compliance with
the conducted emissions limits in 15.107, 15.207,
or 18.307 adopted under FCC 02-157 (ET Docket
98-80) and may be marketed after July 11, 2005
and is not affected by the 15.37(j) or 18.123
transition provisions.
52CISPR AC Line Conducted Limits for All
Transmitters Cont.
- Currently the 05 note has been used on all
devices that meet the older FCC line conducted
regulations and not the new CISPR limits. This
will only be allowed up until July 11, 2004.
After this time TCBs and the Commission will no
longer use the 05 note code.
53CISPR AC Line Conducted Limits for All
Transmitters Cont.
- The CE note is used on all devices that are
tested and comply with the new CISPR requirements
and are granted before July 12, 2004. On July
12, 2004, all new approvals must meet the new
CISPR limits. TCBs and the Commission will not
use the CE note after July 11, 2004. - All devices (both new and previously
approved) marketed after July 11, 2005
must meet the new CISPR AC Line Conducted
Limits.
54CISPR AC Line Conducted Limits for All
Transmitters Cont.
- To update a Part 15 grant that was approved using
the previous Part 15 limits, a Class II
permissive change filing should be submitted
showing compliance with the CISPR AC line
conducted limits.
55CISPR AC Line Conducted Limits for All
Transmitters Cont.
- Special Note
- The policies for filing Class II permissive
changes are different for some Part 18 devices
because certain types of Part 18 devices had no
AC line conducted emissions limits before the FCC
adopted the CISPR limits. - Example Microwave ovens - for a detailed
description see link http//hraunfoss.fcc.gov/eas
_public/SilverStream/Pages/pg_html_fts_res.html?le
tter1344
56CISPR AC Line Conducted Limits for All
Transmitters Cont.
- Special Note 2
- Part 18 RF lighting devices were excluded from
the new CISPR AC line conducted limits by the
last sentence in Paragraph 22 of the Report and
Order (ET Docket No. 98-80 FCC 02-157).
Therefore, RF lighting devices will not have a
Note Code 05 or CE on a grant of Certification.
57Vehicular Battery Chargers (VBC) for Cellular
Phones
- There have been recent questions regarding
whether a battery charger intended for use only
in a vehicle requires FCC Certification.
58Vehicular Battery Chargers (VBC) for Cellular
Phones Cont.
- Exempted per Section 15.103(a)
- The VBC is not promoted for applications other
than use within a vehicle, Section 15.103(a)
exempts digital devices used exclusively in
transportation vehicles - Classified as a digital device under Part 15 of
the FCC rules - Subject only to non-interference
provisions (Sections 15.5 and 15.29) - Certification not required
59Part 15 Water Meter Transceivers In Ground
Testing Guidance
- FCC has recently issued a special guidance
regarding this issue. See link - http//hraunfoss.fcc.gov/eas_public/SilverStream/P
ages/Fpg_html_fts_res.html?letter1366 - This guidance allows testing in ground as opposed
to an open area test site (OATS) - This gives the manufacturer more flexability to
measure system vs. stand-alone configurations.
Allows manufacture to tune power to meet their
installation requirements - Professional installation is required
- Instructions must provide appropriate details for
the installation of the transmitter in
the pits and must specify the
types of pits - Grant will contain conditions accordingly
- Professional installation and specific types of
pits
60Part 15 Water Meter Transceivers In Ground
Testing Guidance Cont.
- Special Guidance
- Use mast. Do not use a tripod with fixed height
- Section 8.1 in ANSI C63.4 should be consulted.
Frequency scans of the EUT field strength with
both polarities of the measuring - antenna shall be made at a minimum of 16 azimuth
angles (nominally 22.5 degrees) around
the EUT
6115.407(d) Integral Antenna Requirement for 5.2
GHz UNII Devices
- The integral antenna rule requires that the
antenna is permanent or not removable.
6215.407(d) Integral Antenna Requirement for 5.2
GHz UNII Devices Cont.
- Acceptable methods
- Antenna and/or antenna connectors are soldered
together - Permanent Loctite or industrial strength epoxy
can be used - A locking connector that cannot be removed, even
with a special tool - Must be locked prior to shipment
6315.407(d) Integral Antenna Requirement for 5.2
GHz UNII Devices Cont.
- An antenna and/or connectors inside of a
non-accessible (there is no need for the user to
ever open the case) - Note that it is assumed that users will open
desktop computers.
6415.407(d) Integral Antenna Requirement for 5.2
GHz UNII Devices Cont.
- Exceptions
- For a 5.15-5.25 GHz UNII mini-PCI card installed
in a notebook computer with built-in antennas - Bios locking feature satisfies the rule
- Antenna with embedded code.
- Code ensures that the proper antenna is used
- Reminder 5.15 5.25 GHz is for indoor
use only. No outdoor antennas.
6515.407(d) Integral Antenna Requirement for 5.2
GHz UNII Devices Cont.
- Unacceptable Methods
- A unique connector is not sufficient
- Bios lock with external antenna
- A locking connector that can be removed with a
special tool does not satisfy the requirement - Heatshrink
- User Warnings
66User Selectable Frequencies
- End user selectable frequencies for non USA
frequencies are not allowed. - User selectable options must be disabled
- This must be clear in all exhibits within the
filing. For example user manual or descriptions
for these options - Section 15.15(b) prohibits adjustments of any
control by the user that will cause operation of
a device in violation of the
regulations.
67Configuration of Antennas for Testing
- The FCC has recently developed 2 concerns
regarding test configurations for the antennas of
a modular approval.
68Configuration of Antennas for Testing Cont.
- 1) Antenna positioning in test setup should
represent typical final product configuration - 2) DO NOT LAY ANTENNAS ON WOOD TABLETOP
69Configuration of Antennas for Testing Cont.
70Configuration of Antennas for Testing Cont.
- In this example the monopole antennas should be
supported in vertical position, e.g., using
foamed-polystyrene blocks
71Configuration of Antennas for Testing Cont.
- Note that this also applies to antennas such as
PIFA. The antennas shown on the following page
should not be placed in contact with the table
top during test. Additionally, the positioning
should be justified in the report.
72Configuration of Antennas for Testing Cont.
73Configuration of Antennas for Testing Cont.
- The FCC has seen that the matching of the antenna
changes when placed too closely to the table top,
which affects the radiation pattern.
74Co-located Transmitters, i.e. Laptop w/ LAN
Bluetooth Cont.
- Co-Location is typically defined as when 2
transmitter antennas are located lt 20 cm apart
from each other, and both transmitters may be
active at the same time. - Each radio must be tested individually
and appropriate test data submitted
with the application
75Co-located Transmitters, i.e. Laptop w/ LAN
Bluetooth Cont.
- The application must also include tests for
simultaneous transmission when the end use device
may function with both transmitters active at the
same time
76Co-located Transmitters, i.e. Laptop w/ LAN
Bluetooth Cont.
- Special care should be taken to investigate
bandedge and intermodulation products - Submit antenna conducted measurements with both
transmitters on, if transmitters share an antenna
77Co-located Transmitters, i.e. Laptop w/ LAN
Bluetooth Cont.
- If radiated data for simultaneous transmission is
no worse (no new intermod, spurs or increased
levels) than individual tests, then also submit
statement that simultaneous transmission was
investigated and no new emissions were found - If new emissions were found during simultaneous
tests, provide data and indicate the
worst case condition
78Cordless Phones
- Cordless phones under Part 15 have typically been
approved under several sections of the FCC rules
such as 15.233, 15.247, and 15.249.
79Cordless Phones Cont.
- The FCC has just released an interpretation that
requires a cordless telephone that operates on
two different frequency bands to be approved
under two separate FCC ID numbers, one for the
base and one for the handset. - For detailed information, refer to FCC
Interpretation Data Base Posting

95RF Exposure TutorialWilliam H. Graff,
AmericanTCB
96Portable vs. Mobile
- Specific definitions for RF exposure
- Mobile Greater than 20 cm
- Portable Less than 20 cm
97What is SAR?
- Close field phenomenon which occurs when an
electromagnetic wave interacts with a biological
medium - Occurs at less than ¼ wavelength
- E and H fields are at relative maximums
98MPE calculation
- MPE calculations assume a linear plane-wave
field. - Considered an overestimate of maximum field
density - Not applicable to distances under 20cm
- Cannot predict interaction with nearby structures
99SAR measurement
- Requires isotropic power measurement systems
- Typically use 3 axis probes in a biological
soup - Soup has electrical characteristics nearly
identical to tissue at specified frequency
100Example Systems
SPEAG
IndexSAR
Aprel/IDX
101P1528 1.4.2 Positioning Rationale
Tilt
Touch/cheek
- 2 pos. intended to encompass normal use, may not
be worst-case - 2 pos. are subset of 4 from ES 590051998
(CENELEC), where experiences showed that 2 pos.
are enough for conservative - Touch position is most repeatable since it relies
on two- or more point contact with phantom
accounts for RF current densities in device case
regions - Tilt position accounts for RF current densities
in external antennas and antenna feed-regions at
top of handset
102SAR Mapping Systems
- control and data capture unit
- field-probe readout electronics
- dosimetric E-field probe
- probe positioner
- unwanted ambient fields

N
(Source IEEE SCC-34/SC-2, P1528 Draft)
104SAR Test Positions
M
- point A is test device reference point
- align point A to ERP on head model
- align vertical center line to M-B
- align horizontal line to N-F
105Limitations of P1528
- Does not address all body worn configurations
- Does not address methodologies above 3GHz
- Does not address non-standard ear-held devices
which do not conform to M to LE or RE line
106SAR Limits
- Experiments with laboratory rats
- Scaled up to humans using known models borrowed
from pharmaceutical industry
107Supplement C Exposure Limits
108Supplement C SAR Limits
109Controlled vs. Uncontrolled
- End users which have a knowledge of radio waves
and can limit their exposure can use Controlled
limits - End users which may have no knowledge of the
limits must use Uncontrolled limits
110Differences in Limits
- Limit for Controlled exposure in the head 4W/kg
(4mW/g) - Limit for Uncontrolled exposure in the head
1.6W/kg (1.6mW/g)
111When is SAR testing required?
- FCC maintains two threshold limits one for
itself and another for TCBs. - TCBs must always follow TCB Exclusion List of
July 17, 2002
112Portable PTT
- Part 80, 90, 95
- FCC SAR data required for PTT above 1W radiated
or conducted - TCB 60mW/f(GHz)
113Portable 15.247 and 15.407
- Below 3GHz
- FCC SAR data if above 50-100mW
- TCB 60mW/f(GHz)
- Above 3GHz
- FCC SAR data if above 50mW
- TCB cannot do
- By law, SAR data required for all portable
UNII devices regardless of Pout
114Modules
- No such thing as RF category Portable modular
approval. (Same FCC or TCB) - Full modular approvals are only permitted for RF
category Mobile modules
115LMA and SAR
- Limited Modular Approvals are permitted but only
for carefully defined host platforms. - Hosts must have similar mechanical constructions.
116Three Host Method
- RF category Portable modules are permitted
under specific circumstances and specific hosts. - Testing to be performed in three each portable
devices (i.e. notebook PC, PDA, etc.) - Unlimited Portable modular approvals never
permitted
117Simultaneous Transmission
- If radiating structures lt20cm then simultaneous
transmission may be of concern. - FCC evaluates co-located devices with
simultaneous transmission - TCB cannot per TCB Exclusion List if second
non-dominate transmitter above 5mw
118Above 3GHz
- IEEE P1528 does not yet define a methodology for
SAR testing above 3GHz, therefore all SAR
evaluation above 3GHz must go to FCC - Expect approvals from FCC to take 90 days
119RF Safety Documents for Issues with Human
Exposure
- ANSI C95.1
- OET 65
- OET 65-C
- FCC Part 1.1037
- FCC Part 2.1091 Mobile Devices
- FCC Part 2.1093 Portable Devices
- TCB Exclusion List
120Future Provisions
- Additional guidance on body-worn configurations
- Release of procedure for TCBs to evaluate SAR
above 3GHz - Likely to be timed with release of DFS procedure
to TCBs
