Wi-Fi 6E
Regulatory Compliance Certification

Overview

As a global leader in testing, inspection and certification. Bureau Veritas provides certification services of internationally recognized standards that include the European Telecommunications Standards Institute (ETSI) and the Federal Communications Commission (FCC). In an increasingly hyper-connected world, wireless connectivity is critical to daily life — it connects everything and everyone, everywhere.

In response to the rapid growth of Wi-Fi 6E technology development and demands in the market, Bureau Veritas offers a wide range of services to support fast and effective market access. Bureau Veritas partnered with Keysight’s regulatory compliance test solution to cover the latest test cases for ETSI EN 300 328 / EN 301 893 and the new European Standard EN 303 687 for Wi-Fi 6E. The collaboration enables Bureau Veritas to address the increased demand for certification and support the latest Wi-Fi 6E standard.

Challenge

Due to congestion in the 5 GHz unlicensed band, regulatory agencies like ETSI and the FCC opened the 6 GHz band for license-exempt access. Therefore the Wi-Fi 6E standard is introduced. The new ETSI Harmonized Standard EN 303 687 extends protection to incumbent services to ensure fair usage of the spectrum. Policymakers in the Americas, Europe, and Asia Pacific (Korea / Japan) have enabled radio local area networks (RLANs) in the 6 GHz band.

Manufacture wants to benefit from the wider bandwidth to provide faster and more stable wireless connectivity by being the first to market with new Wi-Fi 6E products. Bureau Veritas prepared to support regulatory testing of Wi-Fi 6E devices even before the standard was finalized. Moreover, Bureau Veritas works closely with test system vendors to ensure that the regulatory test systems meet continuously evolving standard requirements, improving the turnaround time (TAT) and test capacity to meet customers' expectations.

To support ETSI EN 303 687, modifications are required to the existing test systems. Below are the key areas:

  • Modify adaptivity test, or channel access mechanism (CAM), via a complex test algorithm and extensive post-processing data. The algorithm’s complexity made manual operation unrealistic.
  • Extend test system frequency coverage up to 7.2 GHz for test cases such as multiple-input multiple-out (MIMO) power and transmitter unwanted emissions within the 6 GHz RLAN bands. Measurements beyond 6 GHz require new hardware due to changes in the unwanted emission transmit spectral power mask.
  • Control the Wi-Fi 6E device under test (DUT) and companion device remotely, to work on both test mode and normal operation mode. No one-box-tester in the market supported Wi-Fi 6E devices for this purpose; testers needed the right commercial access point (AP), router, or client.
  • Compile and secure vast quantities of measurement data, result plots, and test conditions easily and efficiently for final reporting.

OUR SOLUTIONS

Keysight released the test cases according to the requirements, by working with Bureau Veritas to validate the operations and test with a real DUT. This close collaboration remains Bureau Veritas' leading position in the global market

Keysight IOT0047A IoT regulatory compliance test solution has enabled Bureau Veritas to:

  • Extend test coverage up to 7.2 GHz and minimize capital expenses by adding the frequency extender. The lab can reuse the existing Keysight signal generators and analyzers.
  • Automate complex test cases such as CAM, adaptivity, receiver blocking, and adjacent channel selectivity test, to enable cooperation between the Wi-Fi 6E DUT and companion device in signaling mode.
  • Simplify reporting by exporting test results, settings, plots, or raw data into a test report in the required format (Excel, Word, PDF).
  • Offer complete test coverage based on the EN 303 687 standard. The IOT0047A standard is backward compatible and supports existing standards such as EN 300 328 (2.4 GHz) and EN 301 893 (5 GHz).
  • Optimize resource management and equipment used by providing the flexibility to split the IOT0047A full system into small systems that focus on signaling or non-signaling test cases.

Results

Bureau Veritas became among the first test labs in the market to provide regulatory certification services for ESTI EN 303 687 before the standard’s formal release. The collaboration between Keysight and Bureau Veritas reduced the regulatory compliance test time of Wi-Fi 6E devices from six days to two days, including setup time. The team shortened the test time through efficient algorithms and full software automation, including DUT control.

“This is an important achievement and milestone for Bureau Veritas and is good news for our clients,” said Pascal Le-Ray, General Manager at Bureau Veritas CPS Technology Products Taiwan. “Through strategic collaborations with Keysight, we were able to set up the regulatory system so our customers can deliver Wi-Fi 6E products to the global market quickly and efficiently.” 

“Keysight is pleased to help Bureau Veritas be among the first in the market to support the latest wireless standards,” said Boon Juan Tan, Vice President and General Manager, General Electronics Measurement Solutions at Keysight Technologies. “Our goal is to help our customers improve their ROI in capital investment and gain a competitive edge in their offers to their clients.”
