Power regulation on Navy platforms can be severely affected if the quality of power is not regulated. Harmonic currents levels are controlled through MIL-STD-461E and MIL-STD-461F, CE101 conducted emissions limits and test thereof.

The quality of power, technically referred to as power quality, can be quantified as a set of parameter values to include variation in voltage amplitude, transient voltages and currents, service continuity, and harmonic current levels in power distribution system waveforms. Power quality is affected when electronic power supplies, and other non-linear loads in particular, cause distortion in the power distribution system of Navy platforms.

In a typical electrical power AC system source, loads are either linear or non-linear. When the load is linear, the current drawn by the load is sinusoidal, which does not distort the waveform. Conversely, non-linear loads produce non-sinusoidal current waveforms, which create a distortion of the voltage waveform. Non-linear loads produce harmonics, which can cause interference to radios, telephones and other communication devices and navigation instrumentation on the Navy platform. The harmonics can also cause a breakdown in the insulation materials of the platform’s electrical wiring.

  1. The RE102 test method in MIL-STD-461E required using a 41” rod antenna below 30 MHz with the counterpoise grounded to the ground plane, which called into question the accuracy of the measurement results above the 10 MHz frequency range. To address this, MIL-STD-461F requires that the counterpoise be isolated from the groundplane.

Recently, Algeria’s regulator, Autorité de Régulation de la Poste et des Télécommunications (ARPT), indicated that Type Approval services are on hold pending the election of a new Director.  During this time, Type Approval certificates will not be issued.  Normal service is expected to resume once the new Director is elected.  

In preparation for the International Telecommunication Union’s (ITU) next World Radiocommunication Conference scheduled for 2019 (WRC-19), FCC Chairman Wheeler announced the appointment of Thomas C. Power as Chair and Christopher J. Murphy as Vice Chair of the FCC’s advisory committee for WRC-19.  The Committee is tasked with providing advice, technical support and recommended proposals on matters relating to the WRC-19. 

Mr. Power is Senior Vice President and General Counsel of CTIA.  Before joining CTIA, Power served as the U.S. Deputy Chief Technology Officer for Telecommunications in the White House Office of Science and Technology Office.  Previously, Power served as Chief of Staff for the National Telecommunications and Information Administration (NTIA), U.S. Department of Commerce, and as Senior Legal Adviser to FCC Chairman William Kennard, where he advised the chairman on broadband, common carrier and mass media matters.

UAE’s Telecommunications Regulatory Authority (TRA) updated Ultra-Wide Band and Short Range Devices requirements in recently published Regulation (Version 2.0) as a written summary of already established requirements.  These requirements are in line with existing European Standards and requirements in ITU-Region 1 countries for these technologies and do not elicit any changes.  See below for the main requirements of UWB devices:

  •         Generic UWB devices shall comply with EN 302 065-1.
  •         UWB devices for location tracking shall comply with EN 302 500-1.
  •         UWB devices for Building Material Analysis shall comply with EN 302 435-1. 

The FDA has issued final guidance for medical device electromagnetic compatibility (EMC).  This final guidance document details a number of primary components that are needed from U.S. manufacturers in order to obtain pre-market clearance or approval for supporting claims of medical device EMC.

Proof of EMC ensures that a device is able to function in its intended environment without introducing excessive electromagnetic disturbance capable of causing electromagnetic interference with other electronically powered devices.  In addition to following existing requirements and testing standards, registrants should include the following information in their applications:

  •         Environment intended for use
  •     Summary of all testing conducted to support EMC claims
  •          List of standards specifications met (including immunity test levels)
  •          Summary of device-specific tests including performance data and pass/fail criteria
  •          Device labeling and supporting documentation of compliance
  •      Details on any changes made to the device for it to pass one or more EMC tests 

It should be noted that additional information may be requested from the FDA Reviewer.  The final guidance document can be found at “Information to Support a Claim of Electromagnetic Compatibility (EMC) of Electrically-Powered Medical Device“. 

South Africa - ICASA Strike

Posted on July 18th 2016 by

Over 50 staff members of the Independent Communications Authority of South Africa (ICASA) have been on strike since July 4, 2106.  The length of the strike is unknown; striking workers are demanding payment of prior salary bonuses.  ICASA has been operating with a shortage of staff so on-going approval projects may soon be impacted.  http://www.fin24.com/Tech/News/negotiations-yet-to-begin-on-icasa-strike-worker-20160714

Mexico’s Type Approval regulator, Instituto Federal de Telecomunicaciones (IFT), recently announced that it will be closed for business from July 18, 2016 through July 29, 2016.  During this period, no Type Approval applications will be able to be submitted to IFT, and applications currently under review are expected to be delayed by up to 2 weeks.  

On July 16, 2016, the FCC adopted new rules for wireless broadband operations in frequencies above   24 GHz, making the United States the first country in the world to make this spectrum available for next generation wireless services.

These new rules open up nearly 11 GHz of high-frequency spectrum for flexible, mobile and fixed use wireless broadband including 3.85 GHz of licensed spectrum and 7 GHz of unlicensed spectrum.     The rules create a new Upper Microwave Flexible Use service in the 28 GHz (27.5-28.35 GHz), 37 GHz (37-38.6 GHz), and 39 GHz (38.6-40 GHz) bands, and a new unlicensed band at 64-71 GHz.

The FCC said it has struck a balance between new wireless services, current and future fixed satellite service operations, and federal uses.  The item adopts effective sharing schemes to ensure that diverse users, including federal and non-federal, satellite and terrestrial, and fixed and mobile, can co-exist and expand.

The FCC also adopted a Further Notice of Proposed Rulemaking (FNPRM)  which seeks comment on several issues.  The FNPRM seeks to apply the adopted flexible use service and technical rules to another 18 GHz of spectrum encompassing 8 additional high-frequency bands, and seeks comment on a variety of other issues including refinements to the performance requirements and mobile spectrum holdings policies, and the sharing framework adopted for the 37-37.6 GHz band.

The goal of these new rules is to create a runway for US companies to launch the technologies that will harness 5G’s fiber-fast capabilities.

On July 8, 2016, the European Commission published in the Official Journal of the European Union the following updated consolidated list of harmonized standards for the R&TTE Directive (RTTED) 1999/5/EC, Radio Equipment Directive (RED) 2014/53/EU and the Low Voltage Directive (LVD) 2014/35/EU.

·         RTTED - 1999-5-EC - Harmonized Standards - C 249 - 8 July 2016

·         RED - 2014-53-EU - Harmonized Standards - C 249 - 8 July 2016

·         LVD - 2014-35-EU - Harmonized Standards - C 249 - 8 July 2016

The R&TTE Directive list of standards will only be used until June 13, 2017.  Currently, there are not many harmonized standards for the RED but it is anticipated that additional harmonized standards for the RED will be updated in the Official Journal over the course of the next year.

 

On July 5, 2016, Vietnam’s Ministry of Information and Communications (MIC) confirmed that National Technical Regulation QCVN 101:2016/TTBTTTT on lithium batteries will come into effect on April 1, 2017.  Existing Type Approval certificates granted prior to April 1, 2017 remain valid until their expiration date. 

On June 13, 2106, Chile’s regulator Subsecretaría de Telecomunicaciones (SUBTEL) released Resolución 1463 that declares that new labelling requirements for cellphone devices must be implemented within 270 days of its publication.  Upon its implementation, devices containing 2G, 3G or 4G technology will be required to display a multi-band stamp on the front of the box/packaging of the device to show the cellular technologies supported. Examples are:

3G graphic

 

The manufacturer or the importer will be responsible for adding the multi-band stamp to the device packaging prior to import and sale in Chile and this requirement will affect both existing and new devices. Cellular-only devices still do not require Type Approval in Chile, however Type Approval is required if the device contains other technologies such as Bluetooth, WLAN and RFID. Upon implementation of this regulation, it will be mandatory for cell-phone devices to operate in all permitted frequency bands of at least one supported cellular technology (2G, 3G or 4G).  http://www.subtel.gob.cl/

Effective July 1, 2016, Taiwan’s National Communications Commission (NCC) will allow the following telecommunication terminal devices to follow the existing Type Approval scheme or to follow the Declaration of Conformity (DoC) scheme:

  •          Telephone
  •          Automatic Alarm
  •          Answering Machine
  •          Fax
  •          Typewriter
  •          Wired Remote Commander
  •          Key Telephone System
  •          Computer Integrating Phone Function
  •          Caller ID Terminal Devices

Under the DoC scheme, the process is simplified and costs are expected to be reduced.  Similar to the standard Type Approval scheme, NCC testing and submission to NCC for assessment is still required, however NCC will then release a DoC with the allocated declaration number.  

In comparison to the standard NCC mark, the “z” highlighted in red below for type approval method will be “C” (for DoC scheme) rather than “T” (for Type Approval scheme).
