Summary

NCT will be required for WiMAX Logo certification from May 1 (CRSL 6.x)

WiMAX Forum will launch new certification testing item - NCT from CRSL 6. The objective of NCT is to evaluate certain SS conformance above the MAC layer, for example IP connectivity across different operator network. It will be required for all certification profiles and there are 3 test cases validated and will be performed from May 1.

The coming CRSL major release 6 will require 5 major testing items such as RCT, PCT, MIOT, RPT and NCT.

Bureau Veritas ADT have test equipment ready to offer NCT testing and have complete testing facilities to accomplish latest certification requirements. top

Introduce the latest information about iIOT in WiMAX Forum to all vendors

Since the iIOT test is going to be implemented to WiMAX Forum Certification, but several things are not clear enough so we would like to share you the latest information in below.

1. Terminology of iIOT is variable and not finalized yet in WiMAX Forum.
• The original term is "iIOT" (from Feb Orlando member meeting to April CWG Taipei meeting)
• And then became "Operator MIOT" (after Taipei meeting on April 10)
• Recently, it became "MIOT module in real Network" (after CWG con-call on April 25)
2. The Active Date is conflict
• 1st June 2009 in CRSL 5.9.0
• But in CWG Chair presentation material, it says the test will be introduced for certification testing at the end of June ’09.
3. CWG did not announce the available testbeds for "iIOT" or "Operator MIOT" or "MIOT module in real Network" to date.

We are keeping contacting with CWG closely to clarify all iIOT issues. Any updated information, we will keep you posted.

For Time to Market and save your cost, we really recommend you to submit for testing before 30th June 200 will be no iIOT issue. top

Bureau Veritas ADT authorized as a testing lab for CTIA and Wi-Fi Alliance Test Plan for RF Performance Evaluation of Wi-Fi Mobile Converged Devices

Bureau Veritas ADT is just approved to test to the CTIA and Wi-Fi Alliance Test Plan for RF performance Evaluation of Wi-Fi Mobile Converged Devices, i.e. CWG-RF (Converged Wireless Group RF Profile Test).Our authorized testing capability can be view at CTIA's website.

What is CWG-RF?

CWG-RF is a test plan that was jointly developed by CTIA and Wi-Fi Alliance to provide detailed radio frequency performance profile in a mixed-network (Wi-Fi and Cellular) environment. Manufacturers of converged handsets and Wi-Fi networking infrastructure devices (access points) can participate in this test program to provide carriers with independent evaluations of their equipments, and carriers can use the test reports to compare handsets from different manufacturers.

What are test items included?

• TRP (Total Radiated Power): measurements to provide information about the reach of a Wi-Fi radio signal sent by a converged phone or AP
• TIS (Total Isotropic Sensitivity): measurements to provide information about how well the Wi-Fi radio can detect an incoming signal in a converged phone or AP

The program also includes:

• Conducted power and sensitivity: measurement of the signals ahead of the Wi-Fi antenna
• Measurement of the reduction in sensitivity (desensitization) of a Wi-Fi receiver caused by the presence of an active cellular transmitter, and to ensure that the performance of the Wi-Fi receiver is within acceptable limits
• Measurements of the desensitization of a cellular receiver caused by the presence of an active Wi-Fi transmitter, and to ensure that the performance of the cellular receiver is within acceptable limits

In addition, to complete the testing a device must also be Wi-Fi CERTIFIED for core Wi-Fi interoperability and WPA2 security, and CTIA certified for cellular performance.

Our Wi-Fi facilities

Bureau Veritas ADT, equipped with complete facilities that can conduct full range of Wi-Fi tests, can offer you real one stop service for your wireless products. Please refer to the following table for our one stop service scope.

Wi-Fi Alliance launches additional new test of 11n Draft 2.0 on April 30

Wi-Fi Alliance replaces version 1.4 with version 1.5.1 of the 11n draft 2.0 test plan. This new plan includes the tests to prevent TKIP (Temporal Key Integrity Protocol) from working with 11n HT (High Throughput) rates. This plan does NOT include the new EAP (Extensible Authentication Protocol) types.

The TKIP tests with 11n HT rates will be initiated by April 30th. The applicant whose device is being tested then will be notified if they pass or fail the tests. 90 days from April 30th these tests will enter into force; therefore, all DUTs must pass these tests after July 29th to be certified for 11n draft 2.0.

The Wi-Fi Alliance Adding no TKIP with HT tests conforms to operation of the DUT to the IEEE standard. The tests ensure that Access Points and Stations do not use HT rates when using TKIP as the encryption cipher. In the 802.11n network, HT rates shall be operated in WPA2 (Wi-Fi Protected Access 2) encryption cipher, and WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption Standard), which is a requirement for some corporate and government users. testing info top

Seminar pre-announcement: WiMAX Forum Certification Seminar

WiMAX Forum CWG is planning to certify 100 notebooks and 50 base stations / mobile stations. Per WiMAX Forum's survey, 89% operators would require WiMAX Forum Certification for devices; 74% plan to sell WiMAX devices through general retail stores, including embedded netbooks, WiMAX dongles, dual-mode dongles and Wi-MAX / Wi-Fi CPEs.

However, the industries have little comprehension on WiMAX certification program and cost if they are not involved in WiMAX Forum's meetings or information collection. As a result, they hesitate to certify their devices. The seminar will demonstrate 1) varied kinds of WiMAX Forum CWG certification programs, 2) certification method for new and serial products. Attendees are expected to know how to certify their products efficiently, faster and economically. Welcome to join us!

• Date: May 21st (Thu)
• Time: 13:00 - 16:40
• Venue: Bureau Veritas ADT Hwa Ya Lab, Taiwan
• Agenda: available Sooner
• Registration: available sooner
• Contact person: Mr. Wang
• Tel.: +886-3-318-3232 # 1622

The Code of Conduct published the new version on energy efficiency of External Power Supply in EU Commission on Apr 8, 2009. (Voluntary)

On 4th of April 2009, the EU Code of Conduct published the version 4 standard to reduce the power consumption of the External Power Supply both under the no-load and load conditions in the output power range 0.3W to 250W.

1. No-load Power Consumption (excluding external power supplies up to 8 W for mobile handheld battery driven applications). The no-load power consumption shall not exceed the limitation as below;

No-load Power Consumption for external power supplies up to 8 W for mobile handheld battery driven applications. The no-load condition power consumption shall not exceed the limitation as below;

2. Energy-Efficiency Criteria for Active Mode (excluding Low Voltage external power supplies) The average active efficiency shall be not less than the limitation as below;

Energy-Efficiency Criteria for Active Mode for Low Voltage external power supplies. The average active efficiency shall be not less than the limitation as below;

**A low voltage model is an EPS with a nameplate output voltage of less than 6 volts and a nameplate output current greater than or equal to 550 milliamps.

MEASUREMENT METHOD

Measurements should be carried out according to the method specified in the "Test Method for Calculating the Energy Efficiency of Single Voltage External Ac-Dc and Ac-Ac Power Supplies (August 13, 2004)", issued by US EPA.

The following measurement results should be reported:

• no-load power consumption
• efficiency at 25 %, 50 %, 75 % and 100 % of full rated output current
