The algorithm for the Source Based Time Averaging transmit control 
and the relevant parameters are given below: 
 
Idle_Time = Duty_Factor * Transmit_Duration 
 
Duty Factor = (100 – Duty_Cycle%) / Duty_Cycle% 
 
Duty_Cycle% = Preset limit for SAR compliance 
 
Source Based Time Averaging Transmit Algorithm 
 
The Boomer-III modem module has an overall transmit Duty Cycle 
limitation of 30% (maximum) to physically protect the modem 
hardware.  
The default Duty Cycle preset in the factory at the time of manufacture 
is 10%.  Other duty factors and SAR evaluation must be addressed at 
the time of OEM integration into any final host/terminal product and is 
the responsibility of the OEM Integrator. 
The algorithm and preset Duty Cycle is recorded in the module 
firmware at the time of manufacture and cannot be altered by the end 
user.
