V8821-The first 5G IoT-NTN satellite communication SoC chip of Unisoc.

V8821

The first 5G IoT-NTN satellite communication SoC chip of Unisoc.

The V8821 is the first satellite communication SoC chip of Unisoc. It adopts the advanced 22nm process and integrates the baseband, transceiver, power management integrated circuit (PMIC), and flash memory/static random-access memory (FLASH/SRAM). It supports the Release 17 IoT-NTN standard and can achieve the functions of two-way voice calls and data transmission. With features such as low power consumption and a small footprint, it can be applied in fields like direct satellite connection for mobile phones, wearable products, satellite Internet of Things products, and satellite vehicle networking products.

General-purpose chips for satellite communication in the IoT-NTN format.

Support IoT-NTN Release 17.

Currently support L-band Inmarsat and S-band Tiantong satellites.

It can be extended to support access to other Non-Terrestrial Network (NTN) satellite systems.

Flexibly adapt to Internet of Things applications, vehicle networking, as well as mobile phones and wearable products.

Support voice functions.

Field tests on site.

Tests in various application environments: ocean, urban fringe, city center, urban park.

Mature solution

It has rich interfaces and supports LPUART, UART, GPIO, I2C, etc.

It supports the TCP/IP protocol, is applicable to a variety of upper-layer services, inherits commonly used Internet of Things protocols, and supports access to existing data platforms.
