2.4 GHz WLAN Devices Now Have EU Class 1 Status

Question: We are a manufacturer of 2.4 GHz Wireless Local Area Network (WLAN) devices and we market our products in the European Union (EU), European Free Trade Association (EFTA) and non-EU/EFTA countries. We recently learned that the EU classification policy for 2.4 GHz devices has changed from Class 2 to Class 1. Can you elaborate on this change and the effect this has on devices for Norway, Russia, and the Ukraine?

Answer: As Class 2 devices, 2.4 GHz WLAN devices were required to be marked with the Alert Symbol (!), and include a list of countries where the device would be sold. As of July 1, 2012, France removed the 100 mW indoor use only restriction for wideband data use in this band; 2.4 GHz  WLAN devices now have Class 1 status with no requirement for the Alert Symbol (!) or any other Class 2 requirement for EU countries; 2.4 GHz WLAN devices are now harmonized. The EFTA countries also adopted this requirement since they follow the EU directives, but they are not bound to follow it in its entirety.

Some EFTA and some non-EU/EFTA countries still maintain national restrictions in this band since they are not bound by the EU directives. In fact, according to the latest ERO Recommendation 70-03 Version 7th of May 2012, Norway, an EFTA country, has a national restriction in this band, therefore such WLAN devices are still considered Class 2 devices in Norway. Russia and the Ukraine are both non-EU/EFTA countries and they also maintain a national restriction in the band in accordance with the latest ERO. Please find attached a newly revised list of the “Class 1” non-restricted devices for Europe in R&TTE Subclass of July 2012.


Testing Inductive (Wireless) Chargers

Question: We manufacture a portable flashlight, whose battery is rechargeable via inductive (wireless) power transfer. We are seeking guidance on the applicable FCC standard and required testing, including RF exposure requirements. Here are some facts about the flashlight:

  1. The flashlight unit is permanently sealed and is powered by a rechargeable Li-ion battery; it functions as a standard battery-operated flashlight driving the main bulb by direct current.
  2. The flashlight is charged by placing it in the provided charging base so that the transmitter coil in the base is aligned with the receiver coil in the flashlight. The charging base is not intended to be held or worn, instead placed on a flat surface at least 20 cm from the user. The proper use of the charging base should minimize the exposure to RF fields.
  3. Power is only radiated when the flashlight unit is placed in the charger base and the battery is charging. During use, the charging base radiated power is approximately 1.0 Watt. During the operation of the charging base, the conditions exist for human exposure to RF fields.
  4. The charging base does not automatically shut off when the flashlight is removed, so a condition for human exposure does exist as long as the charging base is in use.
  5. When the flashlight is in use, there is no exposure to RF.

There are 3 operating configurations:

  • charging with the wall charger adapter
  • charging with the car charger adapter
  • not charging - flashlight in use.

斗地主达人Based on our interpretation of the FCC rules, we believe the following:

The charger and flashlight should be considered "mobile" according to FCC definitions:

  1. It is not fixed
  2. It is over 20 cm in distance from the human body when used as intended.

The assembly also falls under the requirements of "General Population/Uncontrolled" equipment.

斗地主达人In these categories, the device falls under the “1.5 GHz and below” requirement for environmental exposure testing, but it does not meet the requirement threshold of Effective Radiated Power of 1.5 Watts or higher.

Please advise the applicable FCC standard(s), testing and RF exposure limits required to demonstrate FCC compliance.

Answer: We believe that the flashlight with wireless charger is subject to certification under Part 18 of the FCC Rules. Under and , devices are categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use. That is, a radio frequency exposure analysis is not required as part of the Form 731 submission. However, the device must still comply with RF exposure standards and the manufacturer is responsible for ensuring compliance.

The wireless charger/flashlight combination can be treated as a mobile device. A minimum separation distance of 20 cm is required and must be supported by the operating and installation configurations of the transmitter (charger).

For mobile devices, MPE measurement or computational modeling is used to show compliance for §2.1091(c).

As always, our advice is based on our experience with, and knowledge of, the FCC rules and regulations. The FCC is the final arbiter of its rules and regulations.


Re-Classification of 5 GHz WLAN Band

Question: We manufacture 5 GHz WLAN devices; we noticed that the frequency bands 5150 MHz to 5350 MHz and 5470 MHz to 5725 MHz were removed from ERC Recommendation 70-03. What is the status of these frequency bands?

Answer: The frequency bands 5150 MHz to 5350 MHz and 5470 MHz to 5725 MHz are still permitted, but they have been re-classified as mobile, except aeronautical mobile service, and therefore they were removed from ERO Recommendation 70-03, a document which serves Short Range Devices.

The status of the 5 GHz band as a whole is a little bit different. Only the frequency band 5470 MHz to 5725 MHz is Class 1 (subclass 54). The 5150 MHz to 5350 MHz frequency band, even with fully harmonized technical parameters, still has Class 2 status because the use is limited to indoor areas. We understand that the Telecommunications Conformity Assessment and Market Surveillance (TCAM) working subgroup on subclasses is considering the idea that products in the 5150 MHz to 5350 MHz frequency band will remain Class 2 devices, but without the need for notification, in accordance with article 6.4 of the Radio & Telecommunications Terminal Directive (R&TTE). Until this topic is decided upon by the (TCAM), equipment operating in this band has to be notified.


FCC Modifies UPCS Rules

Question: We manufacture Digital Enhanced Cordless Telecommunications (DECT) products. Which frequency band was modified under the FCC’s new Unlicensed Personal Communications Service (UPCS) rules and regulations?

Answer: The FCC’s new UPCS rules and regulations modify the rules governing the operation of UPCS devices in the1920-1930 MHz band (UPCS band), to promote more efficient use of the UPCS band and to facilitate the introduction of a new generation of unlicensed devices capable of supporting broadband connectivity using Digital Enhanced Cordless Telecommunications (DECT) technology. A quick summary of the new rules for UPCS devices follows:

  1. Operation shall be contained to the 1920–1930 MHz band.
  2. The emission bandwidth shall be less than 2.5 MHz.
  3. The power level shall be as specified in §15.319(c), but in no event shall the emission bandwidth be less than 50 kHz.
  4. If access to spectrum is not available as determined by the above, and a minimum of 20 duplex system access channels is defined for the system, the time and spectrum windows with the lowest power level may be accessed.
  5. Emissions outside the band shall be attenuated below a reference power of 112 mW as follows:
    • 30 dB between the band and 1.25 MHz above or below the band;
    • 50 dB between the band and 1.25 and 2.5 MHz above or below the band;
    • 60 dB between the band and 2.5 MHz or greater above or below the band.

Canada – Release of Spectrum Advisory Bulletin for 698-806 MHz Band

On July 13, 2012, Industry Canada released SAB-001-12, a spectrum advisory bulletin addressing radio equipment suppliers and users of low-power licensed radiocommunication devices, including wireless microphones, capable of operating in the frequency range 698-806 MHz。 These devices are licensed on a no-protection, no-interference basis in accordance with Client Procedures Circular 。

In January 2010, Industry Canada released Spectrum Advisory Bulletin , which announced that the Department would no longer accept certification and authorization applications for low-power licensed radiocommunication devices operating in the 698-806 MHz range. SAB-001-10 also prohibited the usage and operation of low-power licensed radiocommunication devices in the public safety bands, 764-776 MHz and 794-806 MHz, beyond March 31, 2011, while those devices already licensed for operation in the remaining portion of the band (i.e. 698-764 MHz and 776-794 MHz) would be allowed to operate until a later specified date.

As indicated in (published in March 2012), continued operation of low-power radiocommunication devices, including wireless microphones, currently licensed to operate in the bands 698-764 MHz and 776-794 MHz, will be permitted until March 31, 2013. After this date, the entire 698-806 MHz band will be used for mobile broadband systems and public safety. Consequently, licences for use of the above-noted devices will not be renewed beyond March 31, 2013.

As a result of decisions in SAB-001-10 and SMSE-002-12, further operation of these systems in the entire 698-806 MHz band will be prohibited beyond March 31, 2013. Manufacturers, importers, retailers and current users of low-power licensed radiocommunication devices, including wireless microphones, are asked to carefully note this impending prohibition and take appropriate transition measures.

It should be noted that there are other low-power radiocommunication devices for which a radio licence is not required. These devices are approved for use in Canada in accordance with technical specifications outlined in , or . This spectrum advisory bulletin does not apply to these licence-exempt devices.

China – New Safety Standard

In May 2012, China’s Quality Certification Center (CQC) released GB4943.1-2011, China Safety of Information Technology Equipment Standard. This standard is very similar to IEC60950-1: 2005 2nd Edition. However, GB4943.1-2011 has additional testing requirements for products which may be used in tropical areas or at altitudes greater than 2,000 meters. Additionally, there is a label requirement for products that are not designed and tested for such use.

The following products are affected by the new standard:

  • AC Power Supply
  • Products with AC Input or powered by DC mains (EWLAN Switches, Server, POE and Telecom Modems)
  • Class III products (MCD, ADC terminals, and other products operating at less than 60 Vdc) will not be impacted by the altitude requirements if the power supply is not sold together with the terminal, and the user manual include following statement: 请根据使用区域的海拔高度选择合适的电源适配器. In this case, the tropical weather requirement still must be evaluated.

Below are the warning labels for products that can only be used in a non-tropical environment and at altitudes less than 2000 meters. The labels should be placed on the products themselves. Also below is the warning statements which are required to be included in the user manuals for such products.

仅适用于海拔2000m以下地区安全使用

(English Translation: can only be safely used lower than 2,000 meters altitude)

斗地主达人仅适用于费热带气候条件下安全使用

(English translation: can only be safely used in non-tropical weather)

This new safety standing will become effective December 1, 2012. Note: all existing CCC approved products that are affected by the new regulation must have their existing CCC certificate renewed with the new standard as well as conform to the new label and user manual requirements by December 1, 2012.

Japan – Upcoming plans for 23 GHz Band

On June 25, 2012, Japan’s Ministry of Internal Affairs and Communications provided notification, under Article: 2。9。2, the plan to establish technical regulations on radio wave properties of transmission equipment for the radio communication system in the 23 GHz band。 The objective is to utilize the 23 GHz band as a substitute for the cable-network to resolve fringe areas where cable-transmission is difficult or inefficient and to recover transmission lines promptly in times of disaster。 The proposed date of adoption is September 1, 2012。

Korea – Amendment to SAR Technical Requirements

On June 25, 2012, Korea’s National Radio Research Agency (RRA) amended Technical Requirements for Measurement and Test Procedure of Specific Absorption Rate (RRA Public Notice No。 2010-45)。 The amendment contained a measurement and test procedure of Specific Absorption Rate for portable wireless devices used within 20 cm of the human body, in accordance with International standards。 The proposed date of implementation for this amendment is January 1, 2012。
