Testing beamforming is tricky but crucial, because the technology introduces a level of complexity on both the infrastructure side and the device side that demands careful characterization and verification before 5G can be successfully deployed.
“Every country wants to say, we are the first country in the world enabling real 5G. That goes down to the operators who are putting pressure on themselves and infrastructure vendors, and in the end all of this pressure is accumulating on the shoulders of the chipset vendors – because they are the first ones in the chain to be required to deliver stable solutions,” said Benoît Derat, senior director of development for EMC, OTA and antenna test systems at Rohde & Schwarz.
