Display and provide various functions to the user through the keyboard, LCD,
audio and other peripherals to meet the user terminal manipulation. 6 top-level
module) application layer terminal software, implementation, and to provide end
a variety of applications, including business applications. (3) mobile terminal
hardware architecture: the mobile terminal hardware including template of RF
transceiver, baseband processor, application processor, power management control
module, external hardware and interfaces. (Note: different phone hardware
platform for the functional division will differ, for example, the baseband unit
module may also be completed part of the multimedia application processing) 1)
RF unit module RF unit template refers to mobile phone RF receiver and RF
transmitter, RF unit module function of the RF chip, the main circuit including:
an antenna, receiver filtering, high frequency amplification, the receiver local
oscillator, mixer, IF, launching the local oscillator, power amplifier.cell
phone jammer can be used in many countries. 2) baseband unit module baseband
unit template to send and receive audio and other data processing. 3)
application processor for the pursuit of higher levels of integration, the
original function coprocessor completed, such as graphics acceleration, video
acceleration, 3D acceleration, the Java acceleration support through the
application processor, application processor extends the cell phone. phone
gradually to support multimedia applications such as video, data, entertainment,
business, and pay. The application processor is generally above core ARM9
capacity. 4) The power management control module power management control module
is responsible for controlling the processor and device power state, as well as
to support the application and device driver interfaces, to meet the demand for
power control. In mobile phones, power management control module is an important
and complex modules, which requires collaboration with other software and
hardware modules. 5) peripheral hardware peripheral hardware, including
keyboard, display, and video cameras. 6) Interface USB, headphone, charger,
Bluetooth, infrared, WLAN, cable, close the wireless interface.cell phone jammer
works well in any nation all over the world. 4 Mobile Terminal Software
Architecture: the mobile terminal software includes the driver software,
operating system, protocol stack (including the communication protocol stack),
application APIs, applications, user interface (UI). 1) physical layer driver
software provides control of the mobile phone hardware such as keyboards, audio
and display interfaces. The application layer software, keyboard, audio, display
device control interface. 2) protocol software module protocol software modules
including GSM, GPRS and WCDMA protocol software, L1 (physical layer) protocol
software and L2 (data link layer) / L3 (network layer) protocol software.
