Vivo conducted a live demonstration of 8K ultra-high-definition (UHD) video streaming powered by 5G at the Mobile World Congress (MWC) Shanghai 2021. The company leveraged an onsite 5G mmWave base station to transmit 8K UHD video from a server to a vivo smartphone, which then wirelessly projected the UHD video to an 8K television. The Vivo smartphone used at the exhibit supports multiple 5G Sub-6GHz and mmWave frequency bands (n257/258/260/261), using NSA dual connectivity (EN-DC).
MWC Shanghai 2021 included a 5G mmWave Zone to exhibit and test the needs of potential application scenarios of 5G mmWave, especially in winter sports events. The zone demonstrated the potential for 5G mmWave for the Winter Olympics.
At present, global 5G service is mainly based on sub-6GHz and mmWave spectrums. Millimeter waves are electromagnetic waves with a wavelength of 1 mm to 10 mm and a frequency range of 30 GHz to 300 GHz. Compared with frequency bands below 6GHz, mmWave has unique advantages such as larger bandwidth, lower air interface delay, and more flexible air interface configuration, which can effectively meet the needs of wireless communication system capacity, transmission rates, and differentiated applications, claims Vivo.
