The purpose of the cooperation is to be strategic partners in driving 5G developments in several areas including mm-waves for 5G radio access and over-the-air (OTA) testing concepts for massive MIMO antenna arrays.
Antenna technology with adaptive beam steering and tracking in order to deliver robust mobile broadband communications in the mm-Wave frequency range in mobile environments is one of the key ingredients of 5G technology.
The joint proof-of-concept demonstration of MediaTek and Rohde & Schwarz at the MWC2017 employs a hierarchical beam architecture for coarse and fine beams and MediaTek’s proprietary calibration and characterisation techniques for beamforming optimization.
The 5G mm-wave signals at 28GHz are created via an R&S SMW200A vector signal generator and MediaTek’s mm-wave prototype platform.
The signal can be received and analysed by the R&S FSW signal and spectrum analyser. Test equipment from Rohde & Schwarz proves to be an ideal tool for the higher frequency bands.
Roland Steffen, Executive Vice President Test & Measurement at Rohde & Schwarz, said: “We are delighted to collaborate with MediaTek to contribute with our test & measurement expertise to 5G technology development. With a strong global footprint for 4G and close cooperation with partners, Rohde & Schwarz is committed to accompany the evolution path from 4G to 5G with innovative test and measurement solutions.”
“We are very pleased to partner with R&S to develop our 5G proof-of-concept trial system at 28 GHz,” said Kevin Jou, Senior Corporate Vice President and Chief Technology Officer of MediaTek. “Our test terminal device adopts a hierarchical beam-searching algorithm for better tracking in a mobile environment and a unique beam-calibration method to improve received signal quality. Together with an established portfolio of world-mode cellular modem solutions, these technologies position MediaTek well to enable the cellular ecosystem a smooth evolution towards 5G.”
