Possible RED Updates on the Horizon

Posted by Ron Tozaki on 2017-11-30 22:27:12

A few months ago, Ofcom, which is UK’s regulatory authority decided to update their regulations to allow Wi-Fi use in the 5.8 GHz band (U-NII-3). It appears that EU/ETSI like UK, is contemplating adding the U-NII-3 band (5.725-5.850 GHz) to the EU domain. Currently EU uses a part of the spectrum (2.4 GHz and 5GHz band), which is becoming increasingly congested and can impair broadband performance. If this happens then this update will open an additional 125 MHz of spectrum in a ‘sub-band’ within the 5 GHz frequency range for Wi-Fi – while ensuring protection for other users, such as satellite services. The extra sub-band increases the number of 80 MHz channels available for Wi-Fi from four to six.

Will You be Complying to the Latest RED Standards in 2018?

Posted by Ron Tozaki on 2017-08-11 08:11:41

The new directive regulating radio equipment usage in EU was in effect starting June 13th, 2017. It was a painful process for us and our customers to get our products in compliance as RED continued to update/change its direction and implementation of the new standard up until the last week of the deadline.

 

To recap, the table below summarizes the RED requirements.

Changes to the 5GHz Wi-Fi band in the UK

Posted by Ron Tozaki on 2017-08-09 07:12:51

The Office of Communications, commonly known as Ofcom, is the government-approved regulatory and competition authority for the broadcasting, telecommunications and postal industries of the United Kingdom. It is similar to how FCC regulates the use of Wi-Fi channels in the United States.

UK currently use a part of the spectrum called the 2.4 GHz and 5GHz band, which is becoming increasingly congested and can impair broadband performance. Ofcom last month decided to update their regulations to allow Wi-Fi use in the 5.8 GHz band (U-NII-3). This decision opens an additional 125 MHz of spectrum in a ‘sub-band’ within the 5 GHz frequency range for Wi-Fi – while ensuring protection for other users, such as satellite services. The extra sub-band increases the number of 80 MHz channels available for Wi-Fi from four to six.

Code RED - Radio Equipment Directive, that is!

Posted by Ron Tozaki on 2017-01-31 01:44:35

ALERT… Come June 13, 2017 the current directive regulating radio equipment will be repealed and new requirements will come into law and all new products will need to comply with the updated directive. We are now less than 6 months away and have to make sure that all products being sold or placed into service in Europe MUST comply to RED (Radio Equipment Directive).

 

Summary of Changes?

Please note that to sell Wi-Fi products into the EU you must be compliant to RED and not R&TTE. One must understand what is being changed so necessary steps can be taken to get Wi-Fi products in compliance. The four basic standards for WIFI are changing.  They will be officially harmonized and listed in the Official Journal as follows:

As shown above, the 5 GHz standard will not be official until after the mandatory June 13, 2017 transition date so you must obtain an EU-type examination certificate from a Notified Body (NB) which will be an added expense to you.

Are you prepared for EN 300 328 v1.9.1?

Posted by Ron Tozaki on 2015-11-17 19:35:13

EN 300 328 covers wideband data systems operating in the 2.4GHz ISM band, including Wi-Fi, Bluetooth, and ZigBee. This is the harmonized standard against which manufacturers must issue their Declaration of Conformity for the Radio and Telecommunications Terminal Equipment (R&TTE) Directive.

Since there were significant changes between ETSI’s V1.7.1 and V1.8.1, it’s natural that electronics manufacturers are wondering what changes are in store for V1.9.1. The latest update, EN 300 328 V1.9.1, is now published and available to download free of charge from the ETSI website.

Does your product need to be tested for SAR?

Posted by Ron Tozaki on 2015-10-28 00:54:55

What is SAR?

Specific Absorption Rate (SAR) refers to the amount of radio frequency electromagnetic field absorbed by the body while using a wireless device. SAR is defined as the power absorbed per mass of tissue and is expressed in units of watts per kilogram (W/Kg). SAR is typically measured over a small sample volume (1 gram or 10 grams). The SAR limit is a measure of the electric and magnetic field strength and power density for a given transmitter over its operating frequency range. In the US, SAR limit for FCC/IC is 1.6 W/Kg over a 1g sample and in Europe, the SAR limit for CE is 2.0 W/Kg for a 10g sample. Any portable products require SAR testing and reports.

Are you prepared for the Level VI Energy-Efficiency Regulation?

Posted by Ron Tozaki on 2015-09-17 15:00:05

The U.S. Level VI energy-efficiency regulation, aimed at energy savings in external power supplies, goes into force on February 10, 2016, and will impact all OEM's selling into the U.S. market. The European Union (EU) also is expected to harmonize with the new efficiency standard.

Radio Equipment Directive (RED) 2014/53/EU

Posted by Ron Tozaki on 2015-08-27 15:00:19

What is Radio Equipment Directive (RED) 2014/53/EU? 

The Radio and Telecommunications Terminal Equipment Directive (R&TTE) 1999/5/EC has been in place for over 15 years now and has served the radio and telecoms world well. Over the last 15 years technology has made many advances in the wireless domain and new ways to ensure compliance was needed.

After review the new European Radio Equipment Directive (RED), 2014/53/EU was published in the Official Journal of the European Commission on May 22nd 2014 which will repeal the R&TTE Directive by June 12th 2016. After this date there is a one year period when either the R&TTE or RED Directive can be applied.

FCC Update for 802.11d - “World Wide Roaming”

Posted by Ron Tozaki on 2014-12-17 09:47:13

FCC plans to prohibit the use of “World Wide Roaming”. What this means is that wireless clients will not be allowed to use the 802.11d specification to automatically configure themselves to their local regulatory domain in the US. This update will require the manufacturer to set the country domain code for their products to US. This new FCC rule will also prevent any end-user from making changes to transmitter RF parameters if it is not authorized to do so in the 2.4 GHz and 5 GHz bands.

FCC Announces New Rules for U-NII in 5 GHz Band

Posted by Ron Tozaki on 2014-08-26 16:00:25

In the Federal Register Vol 79, No.84 of May 01, 2014, FCC has announced that Unlicensed National Information Infrastructure (U-NII) for the 5 GHz band would undergo some changes starting June 2nd, 2014. This change eliminates a loophole where a device could be certified under 15.247 but then illegally modified to operate in the U-NII DFS bands which interfered with Terminal Doppler Weather Radar (TDWR).
