On May 17, 2017, we were advised that Djibouti's Ministère de la Culture et de la Communication, chargé des Postes et des Télécommunications (MCPT), had reinstated its Type Approval Scheme.  In 2013, the MCPT placed all Type Approval applications on hold due to planned changes to its spectrum management system. The Authority advised that no Type Approval certificates would be issued in the interim.
We have been able to confirm the following with regard to the reinstated Type Approval Scheme:
  • The process is paperwork only
  • No samples are required
  • Certificates are valid for 5 years
  • Foreign manufacturers can continue to hold the Approval
  • Estimated lead-time is 3-4 weeks
  • There are no labelling requirements in place
We are still clarifying the full product scope to be included under this new scheme and any impact to products already on the market.

Product Labeling under RED

Posted on April 22nd 2017 by

 

Question: We have a small radio product that we intend to distribute in EU member states. Due to the small size of the product, there is not enough space to affix our company name, company address, and model number, but we want to be in compliance with the requirements of the RED. What options do we have?

Answer: RED Article 10.7 stipulates that “Manufacturers shall indicate on the radio equipment their name, registered trade name or registered trade mark and the postal address at which they can be contacted or, where the size or nature of radio equipment does not allow it, on its packaging, or in a document accompanying the radio equipment. The address shall indicate a single point at which the manufacturer can be contacted. The contact details shall be in a language easily understood by end-users and market surveillance authorities.” Please keep in mind that all RED-compliant products are subject to market surveillance, so all requirements should be implemented as directed.

 

Question: Our wireless device operates between 2402 MHz ‑ 2481 MHz. However, we intend to only use 2424 MHz ‑ 2479 MHz for our Ministry of Information and Communication (MIC) Japanese certification. Is this acceptable for MIC certification?

Answer: The requirement in MIC regulations is that frequencies of operation fall within the frequency band of 2400 ‑ 2483.5 MHz; there are no specific frequencies of operation defined in the regulation(s). The lowest and highest possible frequencies in this band are determined by the 99% bandwidth, which must fall within 2400 MHz ‑ 2483.5 MHz. Furthermore, your device must comply with the emission limit within the authorized band and the emission limits at the band edges. The test report and all supporting documents must indicate the frequency range as defined in the operational description and block diagram, and for which your device was tested. Therefore, for this device, the tested frequency range, to be reported in the operational description, block diagram, and test report, should be 2402 MHz ‑ 2481 MHz.

Question:

  1. We have warehouses in the EU with products deemed compliant with the R&TTE Directive. How long can we continue to sell these products in the EU?
  2. Our products provide Bluetooth connectivity via USB port to other devices such as microcontrollers. Are these other devices subject to the RED?
  3. Our products provide Wi-Fi connectivity through the physical integration of our Wi-Fi hotspot with other devices such as microcontrollers. Are these devices subject to the RED?

Answer:

  1. Based on the minimal description provided, and the RED definition of “placing on the market”, the products in the warehouse may be able to be sold after June 13, 2017. However, before making any final determinations, we strongly recommend that manufacturers/importers read sections 2.1 to 2.5 and 3.1 to 3.6 of the Official Journal of the European Union, 2016/C C272/01, the “Blue Guide” on the implementation of EU products rules 2016.
  2. The BT radio must always be compliant with the RED, but since the BT connectivity is via USB only, easily removable, and not integrated nor installed within the microcontroller, the microcontroller must only comply with the EMC Directive and the LV Directive as a non-radio product.
  3. The physical, or permanent, integration of your Wi‑Fi hotspot into another device, e.g. a microcontroller, now makes that other device a radio product under the terms of the RED. Conversely, as with the BT radio above, if the Wi‑Fi hotspot was not permanently installed, and could be easily removed, e.g. a Wi‑Fi micro-card installed in a slot, the Wi‑Fi micro‑card is the radio product that must comply with the RED, whereas the microcontroller is a non radio product, and therefore must comply with the EMC‑D and the LV-D.

    Note: The RED does not allow application of the EMC Directive, as was allowed under the R&TTE. The RED includes all equipment that contains a radio, including those with a combination of multiple radio products in one, or a combination of radio and non-radio products.

 

On March 31, 2017, South Africa’s ICASA published Government Gazette no. 40733, Regulatory Position on Equipment Type Approval Exemption, to inform the industry of its regulatory position on the equipment type approval exemption as follows:

  • There are no upfront exemptions granted on the basis of types of equipment at this stage.
  • ICASA will develop a framework for the exemption of equipment operating under certain circumstances. ICASA has listed some such circumstances as follows:
    • systems and equipment used for the production and distribution of broadcast and content services
    • test and measurement equipment used by professionals and engineers of a licensed entity in the provision of telecommunications or broadcast services
    • satellite communications equipment
    • equipment for research and development in the laboratory environment
    • equipment for demonstrations of prototypes and testing
    • equipment for sample testing, demonstrations and field trials

    • amateur radios for the purposes of self‑training, intercommunication and technical investigations carried out by amateurs on a non‑commercial basis
    • equipment used by government services for national security and defense networks
    • equipment produced or imported for purposes of exporting and not for use in South Africa
    • spare parts, components to be used for repairs, provided that such part is used in a certified product
  • ICASA will consider entering into and amending existing memoranda of understanding with other regulatory bodies, such as the National Regulator for Compulsory Specifications.
  • ICASA will review its current type approval regulatory framework. The intention is to incorporate the circumstances under which mutual recognition agreements will be recognized, in a bid to improve market surveillance.

 

On March 23, 2017, the FCC took steps to reform certain outdated rules applicable to the 800 MHz cellular service band to facilitate the use of cellular spectrum for mobile broadband services such as long term evolution (LTE). Specific reforms adopted in this revision include:

  • Power Reform: FCC will facilitate broadband technologies by changing its technical rules to permit cellular licensees to transmit the same amount of power across the spectrum band, whether they are deploying a legacy (narrow bandwidth) technology or modern (wider bandwidth) technology like LTE.
  • Co-existence with Public Safety: FCC will continue to ensure co-existence of cellular and neighboring public safety systems by retaining cellular-specific interference resolution rules and procedures, and by engaging stakeholders via a public forum.
  • Consistent Treatment with Similar Spectrum Bands: FCC will treat cellular spectrum consistently with other similar commercial wireless spectrum bands by conforming rules related to power measurement, out of band emissions, field strength, and discontinuance of operations.
  • Unnecessary rules/burdens: FCC will eliminate unnecessary rules and burdens related to application filings, domestic and international coordination, and comparative renewal.

 

On March 17, 2017, Vietnam’s Ministry of Information and Communications (MIC) issued document No. 886/BTTTT-KHCN as guidance on the regulations contained in Circular 42/2016/TT-BTTTT with the following highlights:

EU – RED Guidance

Posted on March 17th 2017 by

 

Recently, the EU Commission released guidance clarifying the current RED situation as follows:

  • The new RED regulations became necessary due to the increasing number of devices with integrated radio capabilities on the market.
  • The aim of the RED is to ensure that all electrical and electronic devices that emit or receive radio waves adhere to essential safety and health requirements, taking care of the efficient use of radio spectrum and electromagnetic compatibility.
  • The RED became applicable on June 13, 2016 with a transitional period of one year, to ensure smooth transition from the former R&TTE Directive.

Currently ETSI, the European standardization organization, has submitted roughly 70% of the total standards needed. Of these, 65 standards were received positively. The EU commission and ETSI are now working on a solution to quickly increase the number of standards available by the beginning of June 2017.

In the meantime, manufacturers and suppliers are advised as follows:

  • In case ETSI does not deliver the missing standards on time, and/or the EU commission and ETSI cannot agree on a solution to speed up the process:
    • the EU commission could, on an interim basis, enforce the former R&TTE rules, for the currently missing standards
    • manufacturers can use alternative conformity assessment procedures to show that their products meet the requirements to legally place their products on the market in the EU and affix the CE marking. This can be achieved by using an accredited test laboratory in combination with a Notified Body.

 

Earlier this year, Canada’s ISED (Innovation, Science and Economic Development) published RSS‑131 Issue 3 with a transition period of July 1, 2017, setting out the certification requirements for zone enhancers used in conjunction with licensed radio equipment in certain radio services. On March 28, 2017, ISED published a notice seeking comments on extending the transition period applicable to zone enhancers for compliance with the requirements of RSS‑131 Issue 3 until January 1, 2018. After January 1, 2018, zone enhancers would have to comply with RSS‑131 Issue 3 in order to be manufactured, imported, distributed, leased, offered for sale, or sold in Canada, and to prevent harmful interference to wireless networks.

On February 23, 2017, Industry Canada released RSS-247, Issue 2 Digital Transmission Systems (DTSs), Frequency Hopping Systems (FHSs) and Licence-Exempt Local Area Network (LE-LAN) Devices, replacing RSS-247, Issue 1, dated May 2015.  Changes to Issue 2 are as follows:

  1. new section 3.3: state the requirement for emissions that fall within restricted frequency bands to comply with the provisions in RSS-Gen, General Requirements for Compliance of Radio Apparatus;
  2. section 5.4(b): reinstated the former e.i.r.p. limit for frequency hopping systems operating in the band 2400-2483.5 MHz, which employ a hopset with less than 75 channels
  3. section 6.2: add a clarification to ensure that emissions that fall within restricted frequency bands shall comply with the provisions in RSS-Gen
  4. section 6.2: state the measurement method for power and unwanted emission limits for licence-exempt local area network devices and digital transmission systems operating in the 5 GHz band
  5. section 6.2.1 and 6.2.2: add a provision to allow original equipment manufacturer (OEM) devices installed in road vehicles to operate in the band 5150-5250 MHz with an e.i.r.p. limit of 30 mW or 1.76 + 10 log10B, dBm, whichever is less stringent;
  6. section 6.2.1.2: clarify the requirement for devices operating in the band 5150-5250 MHz, which have bandwidth that falls into the band 5250-5350 MHz;
  7. section 6.2.2.2 (b): permit the requisite "for indoor use only" notice for equipment operating in the band 5250-5350 MHz to be included in the user manual;
  8. section 6.2.2.3: apply the requirement of e.i.r.p. at different elevations for equipment operating in the band 5250-5350 MHz to outdoor fixed devices only;
  9. section 6.2.2.3: limit e.i.r.p. of OEM devices installed in road vehicles to 30 mW or 1.76 + 10 log10B, dBm, whichever is less stringent;
  10. section 6.2.2.3: allow equipment, other than outdoor fixed devices, operating in the band 5250-5350 MHz having e.i.r.p. greater than 200 mW to either comply with the e.i.r.p. elevation mask or to include a firmware feature to reduce their e.i.r.p. permanently should it be requested by the Department;
  11. section 6.2.3.2: allow equipment operating in the band 5650-5725 MHz with bandwidth overlapping the band 5725-5850 MHz to meet the emission limit of −27 dBm/MHz e.i.r.p. at 5850 MHz;
  12. section 6.2.4.2: modify the unwanted emission limits for LE-LAN devices and DTSs operating in the band 5725-5850 MHz;
  13. section 6.2.4.2: add a transition date for certification of LE-LAN devices and DTSs operating in the band 5725-5850 MHz to have unwanted emissions comply with either provisions in section 5.5 or section 6.2.4.2;
  14. section 6.2.4(b): add a transition date for manufacture, importation, distribute, lease, offer for sales, or sales of LE-LAN devices and DTSs operating in the band 5725-5850 MHz which do not comply with provisions in section 6.2.4(b); and
  15. Annex A: delete the word "pre-installation" to clarify that the verification of e.i.r.p. compliance at different elevations for devices operating in the band 5250-5350 MHz needs to be done at the time of certification (before installation); the verification of compliance must be submitted with the test report for equipment requiring certification.
