They will work together in areas including mm-waves for 5G radio access and over-the-air testing concepts for massive MIMO antenna arrays.
A joint 5G technology proof-of-concept trial for 28GHz beam tracking for mobile environments is being showcased at the Mobile World Congress 2017.
According to Rohde & Schwarz, antenna technology with adaptive beam steering and tracking – for mobile broadband communications in the mm-Wave frequency range – is one of the key ingredients of 5G technology.
The MWC 5G wireless demonstration employs a hierarchical beam architecture for coarse and fine beams and MediaTek’s proprietary calibration and characterization techniques for beamforming optimisation.
The 5G mm-wave signals at 28GHz are created via an R&S SMW200A vector signal generator (pictured) 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.
“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,” said Kevin Jou, CTO of MediaTek. “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.”

“We are delighted to collaborate with MediaTek to contribute with our test & measurement expertise to 5G technology development,” said Rohde & Schwarz’s Roland Steffen, executive vice president of Test & Measurement.
“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.”
