7.1.4 Maximum Bluetooth Output Power
Output power for Bluetooth will be documented in future release of this EPS.
7.1.5 Output Power Restrictions (Main Geo’s)
Intel Reference antenna gain: Max. Antenna Gain 3dBi for 2.4GHz and 5dBi for 5GHz
7.1.6 Channel Configuration Tables / RF Output Power
The values listed in the power table (EEPROM table) below represent the target power for the
calibration process without antennae gain. This value has been verified to ensure margin to
the regulatory limit based on post EEPROM factory calibration measurements using a
diagnostic tool which operates the WLAN card at a ~99% DC (Duty Cycle) taken on both the
main and auxiliary antenna ports.
As part of the factory test process, Intel measures the output power of every card and any
cards that exceed the maximum limits (EEPROM + 1.5dB) will not pass factory test. While in
operation the card adjusts its TX power using a closed loop TX power calibration algorithm. To
do so, a power detector and temperature sensor are used. This algorithm adjusts the power to
within +/-1dB from the target, over temperature and voltage.
Intel uses the following antennae gain value for product and country certification work: 3dbi
for 2.4Ghz and 5dBi for 5GHz.
Intel also incorporates a lower limit to ensure that the compliance of the WLAN card is
maintained. The minimum limits are set by factory process. In MIMO mode this value is the
sum limit. Generally if sum=15 then Tx1 limit=12 dBm and Tx2 limit=12 dBm (exception for
some channels according to the table below).
