Vehicle communication antenna solution_Satellite Antenna Solution_Solution_SHENZHEN VLG WIRELESS TECHNOLOGY CO., LTD

Tiantong antenna satellite communication solution is specially designed for satellite signal transmission and reception. It uses the principle of electromagnetic waves, combined with optimized antenna structure, high-performance materials and intelligent algorithms to ensure stable and efficient communication links. It can provide voice, SMS, data communication, emergency rescue, positioning and navigation services in areas that cannot be covered by ground networks (such as deserts, oceans, Gobi, forests, etc.), where ground facilities are damaged (such as after natural disasters) and in emergency command, ensuring all-weather, high-security and uninterrupted communication.

BYD U8 Satellite Communication Solution Features 1. In areas without network coverage, voice, SMS, and narrowband data communications are realized to ensure that the vehicle network never loses connection and is highly secure. 2. Supports two-way voice calls and SMS, and seamlessly connects with the ground network. 3. One-click SOS rescue and emergency call functions, in line with national standards. 4. Integrated GPS/Beidou positioning. 5. Built-in omnidirectional antenna, no need for satellite alignment, real-time online, stable and reliable. 6. Tiantong WIFI hotspot, supports multiple users, and covers 10-15 meters in open areas.

This solution successfully solved the emergency communication problem of BYD Yangwang U8 when it encountered a blind spot in ground network communication coverage during off-road driving. It was the first domestic launch and has been supplied in batches. It has been well received by BYD and car owners, and has enhanced the competitiveness of customer products.
