UNISOCOne of the major Chinese companies in the field of semiconductors gave a live demonstration at MWC Shanghai 2023, the global mobile communications conference from June 28-30. The company demonstrated its first on-chip SoC (System on Chip) for communications satellites. V8821che sarà presto lanciato sul mercato.

UNISOC presents first SoC chip for satellite communications at MWC Shanghai 2023

Chip UNISOC V8821 It is an innovative product based on standard 3GPP NTN R17defines specifications for non-terrestrial networks (NTN) or networks that use satellites as communication nodes. These networks can provide global coverage and reliable connectivity in areas where traditional cellular networks are difficult or impossible to reach, such as oceans, deserts, mountainous and polar regions.

il V8821 satellite access and altri system support sub-orbit Marine satellites in the L band and Tiantong satellites in the S band, the L band covers the electromagnetic wave frequency band with a frequency range of 1 GHz ~ 2 GHz, and the S band is 2 GHz ~ 4 GHz. Interbands are widely used in satellite communications and terrestrial cellular communications.

V8821 can provide a variety of communication services, including: Transmission not prior to 5G NTN, text messages, calls, location sharing and others. The chip supports TCP/IP, the standard protocol for transmission over the Internet, and is compatible with a variety of high-end services and common IoT protocols. In addition, the chip can support clients to reuse hardware resources in the original solution, increasing application efficiency and avoiding recent high hardware deployment costs.

UNISOC has certified that the V8821 is the result of strong research and development capacity in satellite communications and a commitment to fostering technological innovation. The company also announced the launch of the world’s first new 5G chip solution, and completed laboratory verification and field performance testing of key technology R17 RedCap under the guidance of the IMT-2020 demonstration group. IMT-2020 is an acronym for International Mobile Telecommunications-2020, a global project for the development of fifth generation mobile technologies.
