For suppliers of smartphones or tablets in the European market, the Energy Efficiency Index (EEI) is a labeling regulation that goes into effect at the very start of summer in 2025.
Under the Delegated Regulation (EU) 2023/1669, all smartphones and tablets sold in the EU after June 20, 2025, must have an EEI label. In order to meet this EU requirement, manufacturers must test these devices using the procedures described in the regulation to determine their battery consumption index. That could mean investing in new testing equipment — or it could mean integrating a plug-and-play EEI testing solution that works with existing test setups.
The latter is what Keysight Technologies and SmartViser had in mind with a collaboration built around the UXM 5G Wireless Test Platform.
The Keysight UXM 5G wireless test solution is a highly integrated signaling test platform with multiformat stack support, rich processing power and abundant radio frequency (RF) resources. Supporting 3GPP Release 15 and beyond, the UXM 5G wireless test solution enables engineers to establish a 5G call with a device under test (DUT) in different 5G New Radio deployment modes. It also supports LTE, eMTC, Wi-Fi and C-V2X signaling formats.
Now, users can add to that list of capabilities the integration of SmartViser’s viSer test automation software, which is designed for thorough evaluation of the battery consumption performance of a device. According to Keysight, the new joint solution allows viSer to be used with any configuration of the UXM 5G platform.
SmartViser CEO Gilles Ricordel noted that his company has collaborated closely with EU authorities and policymakers to establish the criteria for EEI verification on smartphones and slate tablets since 2021. “The integration of viSer with the Keysight UXM 5G Wireless Test Setup enables us to cater to the cellular ecosystem that uses Keysight for its device testing needs,” he said.
Muthu Kumaran, general manager for Keysight’s Device Acceptance Solutions, underscored the significance of that integration by noting that a “quick upgrade” is all that device makers need to begin conducting EEI testing immediately. That translates to the possibility of meeting the new EU labeling regulations with the equipment already on the bench.
