Essential Reminder：Wi-Fi Alliance plans to launch 802.11n final program on 30th September 2009

The Wi-Fi Alliance will launch 802.11n final program on 30th September 2009, and the transition period will last for 90 days. In short, members can choose to certify against either the approved 802.11n test bed or the 802.11n draft 2.0 test bed during this period. The members should also be aware that this transition period will be expired from 29th December 2009. Read More

Wi-Fi Alliance test requirements update

【802.11n Test】
(1) Old MIMO tests of 802.11n Draft2.0 (also apply for final 802.11n MIMO too)
•One & Two Spatial Streams - Mandatory
Test initial 11n devices were 2 Tx and 2 Rx (2 x 2)
•Rx A-MSDU - Mandatory
Test the length of an A-MSDU can range between 4k and 8k bytes.
•Rx A-MPDU - Mandatory
Test all frames within an A-MPDU are sent sequentially and all frames are acknowledged with one Block Acknowledge frame from the receiver.
•20/40 MHz operation in 5 GHz band - Mandatory in 5GHz
Test ability to combine two adjacent 20 MHz channels into one 40 MHz channel.(Upper or lower channels)
•RIFS (Reduced Inter Frame Spacing) - Mandatory
RIFS (Reduced Inter Frame Spacing) major increases throughput by about 2%. Test ability to receive RIFS spaced frames with Video streams
•SGI – Short Guard Interval - Optional
Change the Symbol Guard Interval by ½ to test.
•Greenfield - Optional
Test Greenfield headers are used.
•HT Duplicate Mode - Optional
Test ability to used MCS=32 as leads to better error rate performance.

(2) Feature added new MIMO tests
•STBC – Optional
Test of device’s ability of enabling STBC to reduce PER in HT mode when operates in 1x1, 2x2 or 3x3
•Transmitter A-MPDU Aggregation - Optional
Test the ability of transmitting A-MPDU from AP and STA.
•20/40 MHz Coexistence in 2.4GHz band - Optional in 2.4GHz
Test the ability of combining two adjacent 20 MHz channels into one 40 MHz channel in 2.4GHz band.
•3 Spatial Streams - Optional
Test of 11n devices’ ability which can deliver 3 x 3 capabilities with 3 transmitters and 3 receivers to increase the raw data rate.
•Disallow TKIP with HT Rate - Mandatory
Ensure that the Device does not use HT rates when using TKIP as the encryption cypher.

【WPA2 and 802.11n Draft2.0 Test】
Wi-Fi Alliance adds EAP-FAST (Flexible Authentication via Secure Tunneling) and EAP-AKA (Authentication and Key Agreement) to WPA2 and 11n Draft 2.0 certifications.

【WPS Test】
The Ralink RT2800PDAP AP running SW version 1.1.8.0 will replace the Conexant Solos AP in tests 5.1.6 and 5.1.8. For the next 90 days, until November 10, 2009, either AP could be used in these tests. After November 10, 2009, the Ralink will be the only AP used in these tests. The Conexant AP will no longer be used in the WPS test bed.

Essential Reminder: IECEE Informed Members of Certification Requirements for Self Ballasted LED Lamps

IECEE, Worldwide System for Conformity Testing and Certification of Electro-technical Equipment and Components, notified the IECEE Member National Certification Bodies (NCBs) that in order to issue CB Test Certificates for Self Ballasted LED Lamps, NCBs are required to use the requirements as detailed in the attached Provisional Decision Sheet (drafted by CTL-ETF 5) under the supervision of the CTL Chairman and the IECEE Officers.

The notification is also to inform that CB Test Certificates previously issued and based on testing programs/standards other than what is listed in the attached CTL PDSH 0743 (e.g. IEC 60968 only) will be expired and therefore cancelled by the 1st November 2009. Read More

Reminder：Vietnam MIC has a new label / logo

Vietnam MIC (Ministry of Information and Communications of the Socialist Republic of Vietnam) has a new label / logo, under Regulation #TT/06/ 2009/TT-BTTTT dated 24/03/2009, the new logo was applied to products from June 1st, 2009. For the products which already have a DoC or Type Approval certificate before June 1st, 2009, the old logo still can beused. But Authority encourages the change to the new logo.  Read More

ENERGYSTAR Audio/Video Specification Updated (Draft 2.0)

The ENERGY STAR specification for Consumer Audio and Video Products, previously Consumer Audio and DVD Products, is currently under revision. Recently, EPA has made a few modifications to the product test procedure that was circulated on May 19, 2009. The more important changes to the test procedure are highlighted in the Draft 2.0 Version, and note boxes are included to provide further clarification about specific topics.
