The overall control scheme for the repeater unit is described as follows:
 ARM Processor: The ARM processor, being the core of the system control, controls
power supply and paths for various modules in the repeater unit, configures data for
some chips, parses and inserts software protocol stacks, and encodes/decodes channels.
In addition, this processor controls TCP/IP PHY modules and MCU for the control head.
 DSP Processor: The DSP processor handles baseband signals, encodes/decodes voices,
and modulates/demodulates digital/analog signals.
