Meaning
Embedded data configurations stored in non-volatile memory define the maximum transmission power limits for each channel, modulation scheme and frequency band of a wireless module. This look-up matrix ensures that the radio does not exceed regulatory output limits under any combination of operating states. Manufacturers program these parameters into the device during the final stage of factory testing.
Power Allocation
Radio transmitter settings are adjusted dynamically by the driver software to compensate for variations across different bands. Modifying the software power tables allows the hardware to adapt its transmission levels based on the specific antenna gain.
Regional Compliance
International distribution of wireless hardware requires adaptively restricting output power to match different national regulations. When software power tables are updated for a specific geographic region, the radio firmware automatically limits the maximum output power to comply with local rules. Dynamic scaling allows a single hardware design to be certified and sold worldwide.
Calibration Procedure
Factory testing sequences use specialized testing software to measure the actual radiated output power of each manufactured board. Automated test systems adjust the values in the software power tables to compensate for component-to-component assembly variations. Systematic calibration ensures that the final product delivers consistent radio performance across the entire production run.
