(1) Maximum transmitter power (TP) degradation of up to 30% is expected, starting from 80°C ambient temperature on MIMO operation
(2) Regulatory constraints limit TI module output power to the following:
• Channel 14 is used only in Japan; to keep the channel spectral shaping requirement, the power is limited: 14.5 dBm.
• Channels 1, 11 @ OFDM legacy and HT 20-MHz rates: 12 dBm
• Channels 1, 11 @ HT 40-MHz rates: 10 dBm
• Channel 7 @ HT 40-MHz lower rates: 10 dBm
• Channel 5 @ HT 40-MHz upper rates: 10 dBm
• All 11B rates are limited to 16 dBm to comply with the ETSI PSD 10 dBm/MHz limit.
• All OFDM rates are limited to 16.5 dBm to comply with the ETSI EIRP 20 dBm limit.
• For clarification regarding power limitation, see the WL18xx .INI File Application Report.
(3) To ensure compliance with the EVM conditions specified in the PHY chapter of IEEE Std 802.11™ – 2012:
• MCS7 20 MHz channel 12 output power is 2 dB lower than the typical value.
• MCS7 20 MHz channel 8 output power is 1 dB lower than the typical value.
