Keysight and SmartViser Enable Testing for EU Energy Efficiency Index Labeling Regulation

Press Release:

Keysight and SmartViser Enable Testing for EEI

  • Joint solution tests the energy efficiency of smartphones and tablets to meet labeling requirements

  • Solution allows designers to use the SmartViser viSer software with any Keysight UXM 5G Wireless Test Platform configuration to determine a device’s Energy Efficiency

June 11th, 2024

SANTA ROSA, Calif., – Keysight Technologies, Inc. (NYSE: KEYS) and SmartViser have teamed up to provide device makers with a solution to test the Energy Efficiency Index (EEI) of smartphones and tablets to meet the European Union’s energy labeling mandate. With this joint solution, the SmartViser viSer test automation software for mobile devices can be used with any configuration of the Keysight UXM 5G Wireless Test Platform.

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. However, device makers need a plug-and-play EEI testing solution that works with their existing test setups.

To meet this need, Keysight and SmartViser have verified the integration of the two platforms to enable UXM 5G Wireless Test Platform users to use the viSer software to run automated test to thoroughly evaluate the battery consumption performance of a device.

The Keysight UXM 5G wireless test solution is a highly-integrated signaling test platform with multiformat stack support, rich processing power, and abundant RF resources. Supporting the latest 3GPP Release 15 and beyond, the UXM 5G wireless test solution enables engineers to establish a 5G call with a device under test in different 5G New Radio deployment modes. It also supports LTE, eMTC, Wi-Fi®, and C-V2X signaling formats.

Gilles RICORDEL, CEO for SmartViser, said:

“Since 2021, SmartViser has collaborated closely with EU authorities and policymakers to establish the criteria for EEI verification on smartphones and slate tablets, and SmartViser is proposing the viSer Application fulfilling such testing requirement. The integration of viSer with Keysight UXM 5G Wireless Test Setup enables us to cater to the cellular ecosystem that uses  Keysight for its device testing needs.”

Muthu Kumaran, General Manager for Keysight’s Device Acceptance Solutions, said: 

“This collaboration with SmartViser allows us to continue adding value to the equipment investments our customers make by providing valuable new features. With a quick upgrade, device makers can begin conduct EEI testing immediately to meet these EU labling regulations with the equipment they already have on their bench. Not only will this help device makers achieve superior performance that will drive consumer preference for their products, it will address key sustainability challenges. As a company, we are pleased to facilitate this testing.”
