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 MediaTek-R&S joint proof-of-concept demonstration at the MWC2017 employs a hierarchical beam architecture for coarse and fine beams and MediaTek’s proprietary calibration and characterization techniques for beamforming optimization. The 5G mm-Wave signals at 28 GHz 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. R&S’ test equipment prove to be an ideal tool for the higher frequency bands.
Roland Steffen, Executive Vice President Test & Measurement of 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 & 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.”
