Samsung has said it will have 5G technology ready for commercial use during the 2018 Winter Olympics in PyeongChang, South Korea.
This week Samsung said that in partnership with the China Mobile Research Institute (CMRI), it has successfully completed its Beijing trials of 5G prototypes. The two have been working together on 5G development since June 2016 when Samsung joined China Mobile 5G Innovation Center.
Samsung said the tests validated two technologies. One, called spatial modulation, is a method for data rates without increasing bandwidth requirements. The other, called Filter Bank Multicarrier, divides signals into different channels of the same frequency. They were tested at 3.5GHz frequency, the upper end of LTE, which means they will have high-speeds but poor coverage. That will require cellcos to deploy millions of small cells and perhaps limit 5G’s use, at least initially, to metropolitan areas and not rural, less-populated areas. Samsung said one purpose of the tests was to verify the performance of extremely high frequencies – the millimeter wave frequencies – for mobile communication.
Dai Jun Zhang, VP and head of the Samsung R&D Institute China in Beijing, said, “To accelerate the realization of 5G standardization and commercialization in China, we will continue to strengthen our joint efforts with the Chinese government, as well as operators in the future.
