IC Certification for Medical Micropower Network Transceiver Device

Question: We manufacture a medical transceiver device that operates in the band 426–432 MHz as part of Medical Micropower Networks (MMNs). What are the certification requirements for Industry Canada (IC)?

Answer:  Medical transceiver devices that operate in the band 426–432 MHz as part of MMNs are classified as Category I equipment under . They are also license-exempt in accordance with the standard RSS-244 - Medical Devices Operating in the Band 413-457 MHz.

Category I equipment radio devices require a technical acceptance certificate (TAC) in accordance with subsections 4(2) of Industry Canada’s Radiocommunication Act and 21(1) of the Radiocommunication Regulations.

The Certification and Engineering Bureau of Industry Canada (the Bureau) can issue the TAC, or a recognized Certification Body (CB) can issue the TAC.

Following is a list of requirements and test methods that are necessary for certification:

  • Occupied bandwidth, modulation type, frequency stability, EIRP
  • Transmitter spurious emissions, receiver spurious emissions
  • Monitoring system measurements, system threshold power level
  • Monitoring system bandwidth, scan cycle time & minimum monitoring period
  • Frequency band access, discontinuation of a MMN session, duty cycle

FCC Certification for Consumer Signal Booster

Question: We would like to certify our consumer signal booster and we understand that the FCC has a draft measurement procedure out for public comments. Can we use this draft measurement procedure for our testing?

Answer:  If your consumer signal booster is a consumer cellular phone signal booster for wideband and provider-specific application you can use the FCC’s current pre-draft measurement procedure developed by the C63™ Wireless Working Group, RF Booster Task Group, 斗地主达人935210 D03 Wideband Consumer Booster Measurement Guidance DR03-41439. The guidance document is a draft and will most likely change following further comments by the public. The FCC encourages the use of this pre-draft guidance on actual devices in order to determine where the guidance may need further improvements.

The FCC’s new pre-draft procedure contains 11 (eleven) test methods that include specific new procedures that were not previously required for signal boosters. They are:

  • Out–of-band rejection
  • Maximum power measurement
  • Maximum gain computation
  • Intermodulation product
  • Out-of-band emissions
  • Conducted spurious emissions
  • Noise limits
  • Uplink inactivity
  • Variable gain
  • Occupied bandwidth
  • Radiated spurious emissions
The FCC also recently published 935210 D01 Booster Definition v01 which provides guidance for classifying signal boosters operating under , , , and .

Furthermore, the FCC removed signal boosters from its Exclusion List and placed them on the PBA List, which will enable applicants to submit certification applications to the TCBs.
 

Guidance for Certification of Licensed Digital Transmitters

Question:斗地主达人 We manufacture Terrestrial Trunked Radio (TETRA) equipment and would like to know the applicable FCC procedure and/or guidance for digital transmitter certification.

Answer:  The FCC recently updated its guidance and procedure for licensed digital transmitters in KDB971168 to 971168 D01 Licensed DTS Guidance v02. This updated measurement guidance relates to the minimum certification requirement specified in through . It addresses the complexities of measuring licensed devices that use complex digital modulation and coding scheme waveforms that are Gaussian noise-like, but with amplitude statistics that are different within the transmit channel. In the updated measurement procedures, many of the test methods include the use of a spectrum analyzer, a signal analyzer, or an EMI receiver. The measurement procedure covers many aspects of occupied bandwidth and power measurements, among other measurement techniques. For further information, click here
 


Latest Guidance on Wireless Short Distance Inductive Coupled Pads

Question: What is the FCC’s latest guidance on wireless inductive coupled short distance charging pads?

Answer:  Wireless power transfer devices operating at frequencies above 9 kHz are intentional radiators and are subject to either and/or . The applicable rule part is determined by how the device operates, and if there is communication between the charger and the device being charged.

Devices specifically intended for use for wireless power transfer, or inductive charging, require FCC guidance for radio frequency exposure assessment; this includes Part 18 devices. The responsible party or manufacturer must seek guidance from the FCC by submitting a wireless charging application inquiry at .

The initial inquiry shall include the following:

  • "Subject" line stating “Seeking guidance for wireless chargers”
  • complete product description, including coil diameters, number of turns, and current
  • the rule part(s) under which the device will operate, and the reasoning for the rule part(s) determination
  • planned equipment authorization procedure
  • drawings, illustrations
  • frequencies
  • radiated power
  • operating configurations
  • conditions for human exposure 
Intentional radiators that transmit information must be certified under the appropriate Part 15 rules; special types of devices that meet the requirements of are subject only to verification.

A charger may operate in two different modes: charging and communications. If this is the case, it is possible for the device to be approved under Part 18 for the charging mode and Part 15 for the communications mode, if it can be shown that (1) the device complies with the relevant rule parts, and (2) the functions are independent. Part 18 consumer devices can either be certified or self-declared under DoC, only after the required SAR guidance has been received from the FCC through the inquiry process described above and the necessary test requirements have been completed. If the device meets all of the requirements of the appropriate Part 15 rule, it is possible that the power charging function could be approved under Part 15 rather than Part 18.

680106 D01 RF Exposure Wireless Charging Apps v02  provides general guidance on the information necessary to determine RF exposure evaluation and compliance requirements when submitting a wireless charging application inquiry.
