The mobile phone is directly connected to the satellite: UNISOC announces the launch of the first satellite communication SoC V8821.
The advantage of directly connecting mobile phones to satellites is that in extreme environments without signals, they can keep in touch with the outside world and get timely rescue.
As mobile communications move toward the Internet of Everything, in the future 5.5G and 6G eras, satellite networks and ground networks will be deeply integrated.
On July 20, China UNISOC officially announced that it has launched the first satellite communication SoC chip V8821 in response to the new trend of satellite communication development.
At present, the chip has taken the lead in completing 5G NTN (non-terrestrial network, non-terrestrial network) data transmission, short message, call, location sharing and other functional and performance tests with industry partners such as China Telecom, China Mobile, ZTE, vivo, Quectel, Keysight, Penghu Wuyu, and Baicaibang.
According to reports, V8821 has the advantage of high integration, and integrates common functions of communication equipment such as baseband, radio frequency, power management, and storage on a single-chip platform.
The chip is based on the 3GPP NTN R17 standard, uses the IoT NTN network as the infrastructure, and is easy to integrate with the ground core network.
UNISOC said that the V8821 provides functions such as data transmission, text messages, calls, and location sharing through L-band maritime satellites and S-band Tiantong satellites .
In addition, V8821 supports TCP/IP protocol, applicable to various upper-layer services, and inherits common IoT protocols.
For mobile phone manufacturers, V8821 supports manufacturers to reuse hardware resources in the original solution, which can avoid problems such as high hardware cost and long time consumption.
