New FCC Rules for TIA-603-C and Pre-Calibrated Data

QUESTION: We are a manufacturer of licensed transmitters and perform radiated substitution method measurement in accordance with TIA-603-C when measuring spurious emissions and maximum radiated power。 To expedite testing, we use pre-calibrated data, and we would like to know if the FCC will continue to accept this method。

ANSWER: For years the FCC has accepted the use of pre-calibrated data for unwanted spurious emissions and maximum radiated power measurements; however it was recently announced through its KDB that this measurement method will no longer be acceptable as of January 1, 2011. The pre-calibrated data substitution method uses a signal generator to sweep the frequency range of interest and measure each point in space that corresponds to the FCC's rule part limit distance. A tabular set of data represents the pre-calibration of the site. The pre-calibrated data is used to replace substitution procedures in Sections 2.2.12 (j) through (l) and/or 2.2.17 (c) and (d) of the TIA-603-C standard.

In determining the non-acceptance of this method, the FCC stated that the pre-calibrated method has not been recognized by any industry standard, nor has it been provided to the FCC for consideration. The FCC is willing to consider alternative test methods to EIA/TIA-603-C if the C63 accredited Standards Committee or others develop alternative methods.

FCC Class II Permissive Change Rules

QUESTION: We manufacture an industrial transceiver that we certified a year ago。 This transceiver also contains an FM receiver。 We would like to depopulate the FM transceiver by applying for a Class II Permissive Change。 Is this allowed under the FCC's policy?

ANSWER: Significant depopulation usually requires a separate FCC ID because the devices are not electrically identical; Sections 2.908 and 2.933(b) of the FCC's rules and regulations describe identical and change in identification of equipment respectively. However, if the depopulation is not significant, i.e. only minor circuitry removal for the receiver portion, peripheral circuits, or some other digital function, a Class II Permissive Change might be possible. To be sure, you must provide details of the depopulation to your TCB or directly to the FCC. Other examples that may be approved under the same FCC ID, and that could be depopulated and approved under a Class II Permissive Change, such as a base station cordless phone with or without a digital display (for answering machine function), may be found in the permissive change policy at

Radiated Emissions Measurements for Unintentional Radiators

QUESTION: We manufacture unintentional radiators. How do we measure radiated emissions from an unintentional radiator and what detector do we use?

ANSWER: ANSI 63.4 2005 is the standard used to measure radiated emissions. The radiated emission limits for unintentional radiators are specified in FCC Section 15.109. There are both average and peak limits for radiated emissions above 1 GHz, and Section 15.35 specifies the measurement detector function and bandwidth to be used when performing the required measurements.

Above 1 GHz, CISPR 16-1-1 defines two modes of the average detector, namely linear and logarithmic. For radiated emissions measurements at frequencies above 1 GHz, the appropriate average detector is the linear average detector as defined in Clause 6 of CISPR 16-1-1.

There are a number of different types of average detectors on the market today for performing EMI measurements.

For more information, see CISPR interpretation sheet .

FCC Rules for 3G and WiFi

QUESTION: We have a fixed 3G and WiFi router with two antenna ports dedicated to 3G, one internal and one external. We do not sell or provide the external antenna as an accessory. We need to certify our device under FCC Part 22 and 24; what tests are required?

ANSWER: First, you have to consult Parts 22 and 24 of the FCC's rules and regulations, EIA/TIA- 603-C and the FCC's most recent "Permit But Ask List" dated 10/15/2010. Licensed devices, such as 3G routers with integral antenna(s), are tested with the integral antenna. However, a removable antenna(s) is tested at the antenna port. The following tests should be performed:

1。 Antenna conducted power at the antenna connector should be measured if the internal antenna can be removed; if it cannot be removed and then measure EIRP/ERP。

  • If the device is in the mobile category, that is, it is not a licensed base station or cellular repeater or a device which receives its own license to operate, then measure ERP/EIRP on both the internal and external antenna port using the highest allowed antenna gain. For FCC Parts 22, 24 and 27 devices, measure the ERP/EIRP maximums for non-base station, non-cellular repeater type devices. Consult FCC rule Sections 22.913, 24.232 and 27.50.
  • As a manufacturer you are relieved of the obligation to ensure that your device does not exceed the ERP/EIRP limits by saying you do not supply the antenna. The FCC expects that a maximum antenna gain restriction will apply to the device.
  • For Maximum Permissible Exposure (MPE), if the device is not licensed at the time of installation, then you must provide MPE calculations and possibly MPE measurements with the certification application。 In order to do this you would have to limit the gain of any external antenna used for the device, and the maximum gain would be listed on the grant。 The only way to avoid performing MPE is to demonstrate during the certification process that you will not sell the device to anyone who does not obtain a license to operate it。 If the device is sold to someone who does not obtain a license, thus operating under the license of a base station, for example, CPE equipment, then MPE and a maximum stated antenna gain must be provided at the time of device certification。

2. Measure antenna spurious power at the antenna connector, including spurious and harmonics as well as band edges.

3. Measure radiated spurious emissions with the external port terminated in its characteristic impedance and perform conducted and radiated spurious emissions.

4。 Test frequency stability, voltage and temperature at the antenna port。

5. Measure occupied bandwidth at the antenna port.

6。 Measure any other required tests for licensed devices。

FCC: PROPOSED INITIAL STEPS TO OPEN TV SPECTRUM TO NEW WIRELESS BROADBAND SERVICES In a Notice of Proposed Rulemaking published on November 30, 2010, the FCC suggested making more efficient use of the nation's airwaves and set the stage for voluntary broadcast spectrum auctions that could provide consumers with the robust mobile broadband services they demand while preserving over-the-air TV that many rely upon。 The resulting efficient use of airwaves will help ensure that America leads the global wireless revolution and enjoys the resulting jobs and economic growth。

Specifically, the NPRM proposes that wireless broadband providers have equal access to television broadcast frequencies that could become available in spectrum auctions. The Notice seeks comment on establishing new allocations for both fixed and mobile wireless services in the TV broadcast bands. The Notice also explores enabling TV stations to voluntarily combine their operations and distinct programming lineups on a single TV channel. The Notice requests comment on the proposed rules that would enable TV broadcasters to opt to share channels by further tapping the technical capabilities that became available following the nation's historic transition to digital television in 2009. Finally, the Notice of Proposed Rulemaking seeks comment on steps that would improve TV reception on the VHF channels (2-13), such as by increasing transmitting power and establishing minimum performance standards for indoor antennas. These improvements could provide better VHF reception for consumers and encourage broadcasters to use valuable VHF channels in the future. 

FCC: PROPOSAL TO BOOST SPECTRUM RESEARCH AND SPECTRUM-EFFICIENT WIRELESS TECHNOLOGIES On November 30, 2010, the FCC announced a new proposal to promote investment and create jobs in wireless broadband。 Citing past achievements such as Wi-Fi and PCS that grew out of experimental licensing, the FCC proposed to overhaul its experimental licensing rules to streamline the process by which new devices and technologies can move from R&D to deployment。 The FCC proposed the following three types of program licenses:

  • Research license: This would allow universities, laboratories, and other qualified research institutions to conduct experiments over a wide variety of frequencies and other operating parameters.
  • Innovation Zone license: This would identify discrete geographic areas -- generally relatively remote locations -- where researchers could conduct a wide range of experiments.
  • Medical license: This would allow medical institutions to innovate and develop new devices that can save lives, have a significant impact on reducing medical costs for consumers, and provide new treatment options for wounded service men and women.
