Interconnection transmission and interaction components are the core carriers for communication terminals to achieve multi-dimensional connections and convenient operations. They mainly include 5G/4G radio frequency modules, WiFi 6/7 modules, Bluetooth modules, NFC chips, satellite communication modules, touch screen driver chips, and voice interaction chips, etc. They support high-speed and stable interconnection between communication terminals and mobile networks, WiFi networks, other intelligent devices, and satellite systems, enabling functions such as high-definition voice calls, ultra-high-definition video transmission, data synchronization of multiple devices, and near-field payment; at the same time, they support diverse human-computer interaction methods to meet the core requirements of full-scene connection and convenient operation of communication terminals.
