MultiPoint Newsletter - December 2011 Issue

Dear Colleague,

We have provided typical questions and answers that represent in most cases technical opinions with justification in FCC, IC and CE requirements. The particulars of the product for certification must be considered with respect to the applicability of these questions and answers. We hope you find our update valuable and welcome your feedback if you have any special needs or questions. Call us at 703.689.0368 for your testing requirements. You can view archived issues of MultiPoint at our website.

  FCC Part 101 Transceiver Verification Procedure

Question: We manufacture microwave 2.5Gbit/s digital transceivers at 73.5GHz/83.5GHz and would like to know how to obtain FCC approvals.

Answer: Microwave transceivers operating at 73.5GHz/83.5GHz must adhere to FCC Part 101 verification or certification procedures, provided they employ digital modulation techniques and meet the minimum bit rate requirement of 0.125 bit/s/Hz; specifically your transceivers must be tested in accordance with . Verification is all that is required, per . If you want your transceivers certified instead, follow the applicable procedures in , application for certification.

If you choose to verify your transceivers, it’s very important that the model numbers on the transceivers be consistent with the model numbers in the verification test report. The verification test report must always be kept on file in the event the FCC requests a copy to review. This may occur if interference issues are reported by the military, government agencies or other commercial wireless operators.

  MPE: Wireless Charging Devices 100 kHz – 205 kHz

Question: We have a wireless charging device that operates from 100 kHz to 205 kHz. How do we apply the FCC’s Maximum Permissible Exposure (MPE) limits when the limit ends at 300 kHz, and the Specific Absorption Rate (SAR) limits do not go below 300 MHz?

Answer: If your wireless charging device is mobile and not portable, meaning that when operating, the RF-generating charging elements are more than 20 cm or greater from a person, SAR may not be applicable.

MPE RF is applicable for FCC Part 15B and Part 18 wireless chargers, inductive chargers and wireless charging pads designed for mobile applications, even though MPE limits end at 300 kHz。

At the recent Telecommunications Certification Body Council (TCBC) training seminar this past October, the FCC stated that wireless charging devices can only be examined on a case-by-case basis, and as such, a KDB inquiry should be sent to in order to determine MPE limits below 300 kHz, since currently there are none。  When sending this inquiry, the subject line should state “Seeking guidance for wireless chargers” and it should include the following information:

  1. Complete product description;
  2. The rule part(s) under which the device will operate, and the reasoning for the rule part(s);
  3. Planned equipment authorization procedure;
  4. Drawings, illustrations;
  5. Operating frequencies;
  6. Radiated power;
  7. Operating configurations;
  8. Conditions for human exposure, and
  9. Operating configurations for different charging devices.

The FCC also stated that to determine MPE limits for wireless charging devices operating below 300 kHz, it may use the Electric field (V/m) and Magnetic field (A/m) limits at 300 kHz from and a 10-15 cm separation distance.

Review 680106 D01 RF Exposure Wireless Charging Apps v01 for general guidance on submitting a wireless charging application inquiry to the FCC and the information necessary to determine RF exposure evaluation and compliance requirements.

  TCB Market Surveillance Program

Question: We are a manufacturer of wireless devices and we are curious about the TCB market surveillance program. Are we required to respond to a request for an audit sample?

Answer: 斗地主达人The FCC is very serious about its Telecommunications Certification Bodies (TCBs) market surveillance program. of the FCC rules and regulations requires that a TCB conduct appropriate post-market surveillance activities in accordance with ISO/IEC Guide 65.

According to these rules, the grantee is expected to have production samples available in the event the device is requested as a sample, and the grantee must ensure that production samples are available for at least one year after the last production date, for post-market surveillance testing. Explanations such as “item no longer manufactured”, or “not marketed in the United States”, do not absolve the grantee from providing a sample.

A grantee who is unwilling to send requested audit samples to a TCB may cause the FCC to block their grantee code until the audit issue is resolved, or the grantee may be referred to the FCC’s enforcement bureau.

Following an audit, the TCB is obligated to immediately send a full report to the FCC and to the grantee explaining any non-compliance issues, to seek resolution on the non-compliance issues, and to send a resolution/follow-up letter to the FCC.

The TCBs are to utilize the following criteria when conducting audits:

  1. 5% of all products certified under scope A or scope B on a yearly basis
  2. 2% of all products certified under scope C on a yearly basis
  3. 1% of all products with SAR certified on a yearly basis
  4. Products audited must be tested; paper audits are not sufficient for audits
  5. Audits should be performed throughout the surveillance year and not all at the end or after the surveillance year
  6. The number of audits is based on the number of grants, and not unique FCC identifiers
  7. The percentage of products to be audited is based on grants issued in a surveillance year

  New FCC UNII Test Procedure

Question: We are a manufacturer of UNII devices and we understand that there are new test procedures. What are they?

Answer: The FCC replaced the guidance contained in Public Notice DA 02-2138 dated August 30th, 2002 with the procedure specified in 789033 D01 General UNII Test Procedures v01, in order to meet the technical requirements of FCC 15.407. Effective January 1, 2012, this new procedure will replace the aforementioned public notice; however, the FCC will accept applications employing either the guidance of DA 02-2138 or the new test procedure 789033 D01 UNII General Test Procedures v01, in its entirety.

Please note that the new procedure does not cover Dynamic Frequency Selection (DFS) functionality testing. When evaluating DFS, refer to FCC Order, ET Docket No.03-122 (FCC 06-96).

When testing equipment that is capable of transmitting with multiple outputs, as in Multiple Inputs Multiple Outputs (MIMO) with beam-forming capability, consult KDB 662911斗地主达人 for additional guidance.

US: FCC Approval of Rulse for Medical Micropower Networks (MMNs)

Just On November 30, 2011, the FCC adopted rules to allow wireless networks of microstimulators designed to treat paralysis and other conditions. The FCC approved the use of MMNs in four blocks of the 400 MHz spectrum band, despite opposition from some groups concerned about interference.

Microstimulators implanted next to nerves can stimulate those nerves through electrical charges, causing muscles to contract and limbs to move. MMNs can link dozens of those stimulators to devices that take in signals from the human nervous system, bypassing areas of the nervous system that have been impaired by strokes or spinal cord or brain injuries.

The FCC initiated this proceeding in response to a petition from the Alfred Mann Foundation, which has built prototype MMN systems and conducted extensive testing that demonstrates that this new medical technology can reliably operate in shared spectrum to deliver vital therapies.  The action by the FCC will allow devices such as those being tested by Alfred Mann to proceed on the path to patient use as well as inspire researchers to begin work on the next generation of implanted medical radio network.

EU: Introduction of Harmonised Technical Conditions for the Terrestrial 2 GHz Band

The European Commission recently just launched a public consultation on the introduction of technical harmonisation measures at EU level in the terrestrial 2 GHz band (1900-1980 MHz, 2010-2025 MHz and 2110-2170 MHz). The use of this band in the EU is currently restricted only to UMTS, whereby parts of it remain largely unused. The collected feedback will be assessed in the process of preparing a Commission Implementing Decision in 2012, supported by an Impact Assessment. The consultation closes on January 18, 2012.  

Bolivia: Mandatory Type Approval

On August 8, 2011, Bolivia implemented a new law, , requiring mandatory Type Approval for radio and telecom equipment entering the Bolivian market。

At this time, there is no homologation procedure under the new law and Bolivian Telecommunications Authority.  We anticipate the procedure will be available in late December 2011.
