Bureau
Veritas ADT continuously provides Over The Air Performance Testing
Service for different technologies (OTA, RPT, CWG-RF)
Bureau Veritas
ADT, authorized for CATL License and Service Agreement in CTIA ,WiMAX
RPT testing in WiMAX Forum and CWG-RF in Wi-Fi, is closely working
with the industry to provide Over The Air Performance Testing Service.
It has been equipped with complete facilities to conduct CTIA OTA,
WiMAX RPT and Wi-Fi CWG RF tests and can offer a real one stop service
for mobile terminals. Please refer to the table below for details.

Over the
Air (OTA) is a radiated performance test for radio mobile
communications devices to verify their 3D ˇ§Radiated RF Transmitter
Powerˇ¨ and ˇ§Radiated Receiver Sensitivityˇ¨. Its main test items
include TRP (Total radiated Power) and TIS (Total Isotropic Sensitivity)
two categories respectively.
Radiated
Performance Test (RPT) includes the transmit and receive
performance aspects of WiMAX Subscriber and Mobile Stations in a
radiated test configuration. These tests are used to evaluate the
radiated performance of devices that utilize WiMAX air interface
profile.

89%
survey responsers indicating their companies would require WiMAX
Forum Certification for devices
Per an industry
research report provided by WiMAX
Forum, of the more than 70 participants, more than 50 responded
to a question on the importance of certification. 89% of those surveyed
indicated that their companies would require WiMAX Forum Certification
for devices, while 10% believe it to be a definite to benefit to
device manufacturers wishing to build for these operators. Only
a single operator definitively said that Certification was not at
all required. Another important data point is that 74% of respondents
plan to sell WiMAX devices through general retail stores. data

Wi-Fi
Alliance is planning to announce certification program for new EAP
types on May 20, 2009
Wi-Fi Alliance
is planning to announce the certification program for the new EAP
(Extensible Authentication Protocol) types on May 20, 2009. The
new EAP types testing - EAP FAST (Flexible Authentication via Secure
Tunneling) and AKA (Authentication and Key Agreement), will affect
the WPA2/WPA (Wi-Fi Protected Access) and 802.11n draft 2.0 test
beds and test plans.
WFA Test
Plans
The WPA2/WPA
(802.11a/b/g) and 802.11n Draft 2.0 test plans are being finalized
and will be available prior to the May 20 launch. Changes include
additional testing for the new EAP types and identification of devices
used for individual test cases.
Beginning on
May 20, 2009 all members will be given a 90-day grace period to
optionally test the new EAP types on new or additional product applications.
During this 90-day period, members can request an Authorized Test
Lab (ATL) to test for the new EAP types. If all tests pass, the
member will be issued a certificate which includes the new EAP types.
If the product fails to pass the additional EAP tests, the product
will still be certified for all other requested certifications that
pass successfully.
Products submitted
after the 90-day grace period, on or after August 19, 2009, will
be required to support and pass the new EAP testing in order to
be certified for WPA2 802.11a/b/g or 802.11n draft 2.0. read

The
5th Ecodesign Implementing Measures published in OJ on Apr 6, 2009
On 6th of April
2009, the European Commission adopted the ecodesign Regulation (EC)
No 278/2009 regarding no-load condition electric power consumption
and average active efficiency of external power supplies. (The effective
date will be on Apr 27, 2010)
1. First Stage:
One year after this Regulation has come into force.
The no-load
condition power consumption shall not exceed 0.50 W and the average
active efficiency shall be not less than the limitation as below:
| Output
Power |
MINIMUM
ACTIVE EFFICIENCY |
MAXIMUM
NO LOAD POWER |
| Po < 1W |
>= 0.50
x Po |
<=
0.50W |
| 1.0W <=
Po <= 51W |
>= 0.09
x Ln(Po) + 0.5 |
| Po > 51W |
>= 0.85 |
2. Second Stage:
Two years after this Regulation has come into force.
The no-load
condition power consumption shall not exceed the limitation as below:
| Output
Power |
AC-AC
external power supplies, except low voltage external power supplies |
