EB Delivers First Multi-antenna OTA Test Solution to LG
LG Electronics has selected EB as the company to deliver the industry’s first multi-antenna Over-the-Air (OTA) performance testing solution for its mobile devices. The solution will enable the company to test full mobile device functionality and performance in realistic radio channel environments without any compromises to the performance verification.
The multi-antenna OTA testing application is built around the EB Propsim F8 radio channel emulator and related channel modeling software allowing LG to test final mobile phone designs with embedded antennas and the cover in place. The OTA application utilizes state-of-the-art geometrical radio channel models to replicate real network-like conditions in the laboratory.
The OTA testing application enables repeatable testing in various radio channel conditions, which shortens the mobile phone development cycle and enables early market introduction of new mobile devices. It was chosen to enable LG to ensure the highest performance for mobile devices and therefore, further improve the end-user experience of its customers.
The multi-channel EB Propsim F8 emulator is an essential part of the OTA testing solution as it enables the testing of mobile phones utilizing MIMO technologies. Standards like 3GPP LTE and Mobile WiMAX plan to utilize MIMO technology and multi-antenna OTA testing can offer significant improvement compared to conventional conductive cable testing, especially as it pertains to these standards.
“After deep technical discussions between EB and LG experts, EB was able to offer us a solution which takes our testing capability to the next level,” said Yongsang Cho, a chief research engineer of LG Electronics Mobile Communications Co. “We are confident that multi-antenna OTA testing will enable us to further improve the quality and performance of our mobile phones as the testing now includes the antenna effects which are crucial in multi-antenna systems. EB’s OTA solution grants us the ability to test mobile phones in a controlled laboratory environment and bring the test scenarios to reality.”
