Reverse Link Budget
Determine maximum allowable path loss and hence coverage for voice and data at different rates

Forward Link Budget
Verify that sufficient power is available to support performance within the footprint dictated by the reverse link
Verify the system has sufficient power to support the mix of FCH and SCH
The maximum path loss is the allowable maximum propagation loss through the air without considering shadow fades





The maximum path loss in dB can be determined by（空中路徑損耗）:
(Max. Path Loss)= (Mobile EIRP) - (Building Penetration Loss) + (BS Rx Antenna Gain) - (BS Cable Loss) - (Fade Margin衰落余量) + (Soft Handoff Gain) - (Receiver Sensitivity)
