Ultra Wide Band (UWB) technology is a wireless carrier communication technology that does not use a sine carrier, but uses nanosecond non-sine wave narrow pulses to transmit data, so its frequency range is very wide.
UWB technology has low system complexity, low power density of the transmitted signal, insensitivity to channel fading, low interceptability, and high positioning accuracy. It is especially suitable for high-speed wireless access in dense multipath places such as indoors.
With the popularization of digital car keys, high-precision positioning is increasingly demanded in the market. To meet this demand, Shengrun Technology has launched a digital key that integrates a BLE+UWB dual-mode solution, which adapts to the vast majority of mobile phone ecosystems on the current market, providing users with high-precision, convenient, and seamless positioning capabilities.
This solution is based on the TI CC2642-Q1 automotive-grade chip Bluetooth 5.1 technology. The smart key is equipped with a built-in BLE+UWB module, which can seamlessly recognize and locate with the BLE devices and UWB antennas installed in the car body. It also supports ICCE and CCC 3.0 protocols.
