For example, the main panel, gps, camera, wifi, bluetooth, etc.) drive the version number of the aggregate。
6. Baseband (b)Aseband is a circuit in a mobile phone that completes the decomposition, deturbanization, detachment and decodement of wireless signals in the mobile network and transmits the digital signals that were eventually decoded to the upper processing system for processing
7. We make phone calls, access to the internet, text messages, etc., all through instructions from the upper processing system (usually standard at directives) to the base belt part, which is implemented by the base belt part, which, upon completion of processing, establishes a logical channel between the cell phone and the wireless network through which our voice, text messages or internet data packages are transmitted。
8. With the development of software radio technology, the base segment of the mobile phone up to 2012 can essentially be used to decode wireless signals, while software radio technology can easily upgrade the base segment to meet different needs or amend the base segment of the belt。
