The baseband version is the driver version number used by the modem of the mobile phone, and the modem is mainly responsible for the communication functions of the mobile phone (making phone calls, texting, data exchange, etc.). )! The kernel version is the version number of mobile phone hardware (such as motherboard, GPS, camera, WiFi, Bluetooth, etc.). ) drive assembly! Baseband is a circuit in the mobile phone, which is responsible for demodulating, descrambling, despreading and decoding the wireless signals in the mobile network, and transmitting the finally decoded digital signals to the upper processing system for processing. With the development of software radio technology, the baseband part of mobile phones can basically decode wireless signals with software.

As far as the same mobile phone is concerned, the higher the baseband version, the better, but as a user, you may not feel obvious changes.
