vivo showcased its first satellite communication prototype at the recently concluded MWC Shanghai 2023.
The device is based on the vivo X90 Pro+ smartphone with custom modifications and is designed to support two-way satellite communications using the 3GPP R17 non-terrestrial network (NTN). It uses an integrated solution with a radio frequency (RF) baseband and an internal antenna, supports dual-frequency n255/n256, and is compatible with the Inmarsat/Tiantong-1 satellite system.
The prototype is equipped with UNISOC’s first satellite communication system-on-a-chip (SoC), the V8821, which will be mass-produced soon.
V8821 can communicate using L-band Inmarsat and S-band Tiantong satellites. It can also be expanded to work with other high-orbiting satellite systems to provide communication in areas like the ocean, urban fringe, and remote mountains where cellular networks are unavailable.
V8821 offers flexible hardware configuration, allowing customers to reuse hardware resources from their current solutions. This enhances deployment efficiency, avoids high costs, and reduces time consumption.
With this revolutionary satellite communication technology, Filipinos will be able to send and receive information in areas where there is no cellular network coverage, such as wilderness, oceans, and forests.
