For devices that operate in only one of the U-NII-1 and U-NII-2A bands, the normally required SAR
procedures for OFDM configurations are applied. For devices that operate in both U-NII bands using
the same transmitter and antenna(s), SAR test reduction is determined according to the following：
1. When the same maximum output power is specified for both bands, begin SAR measurement in U-
NII-2A band by applying the OFDM SAR requirements. If the highest reported SAR for a test
configuration is ≤ 1.2 W/kg, SAR is not required for U-NII-1 band for that configuration (802.11
mode and exposure condition); otherwise, both bands are tested independently for SAR.
2. When different maximum output power is specified for the bands, begin SAR measurement in the
band with higher specified maximum output power. The highest reported SAR for the tested
configuration is adjusted by the ratio of lower to higher specified maximum output power for the
two bands. When the adjusted SAR is
≤ 1.2 W/kg, SAR is not required for the band with lower
maximum output power in that test configuration; otherwise, both bands are tested independently
for SAR.
3. The two U-NII bands may be aggregated to support a 160 MHz channel on channel number 50.
4. Without additional testing, the maximum output power for this is limited to the lower of the
maximum output power certified for the two bands. When SAR measurement is required for at
least one of the bands and the highest reported SAR adjusted by the ratio of specified maximum
output power of aggregated to standalone band is > 1.2 W/kg, SAR is required for the 160 MHz
channel. This procedure does not apply to an aggregated band with maximum output higher than
the standalone band(s); the aggregated band must be tested independently for SAR. SAR is not
required when the 160 MHz channel is operating at a reduced maximum power and also qualifies
for SAR test exclusion.
B) U-NII-2C and U-NII-3 Bands
The frequency range covered by these bands is 380 MHz (5.47 – 5.85 GHz), which requires a
minimum of at least two SAR probe calibration frequency points to support SAR measurements.
when Terminal Doppler Weather Radar (TDWR) restriction applies, all channels that operate at 5.60
– 5.65 GHz must be included to apply the SAR test reduction and measurement procedures.
When the same transmitter and antenna(s) are used for U-NII-2C band and U-NII-3 band or 5.8 GHz
band of §15.247, the bands may be aggregated to enable additional channels with 20, 40 or 80 MHz
bandwidth to span across the band gap, as illustrated in Appendix B. The maximum output power for
the additional band gap channels is limited to the lower of those certified for the bands. Unless band
gap channels are permanently disabled, they must be considered for SAR testing. The frequency
range covered by these bands is 380 MHz (5.47 – 5.85 GHz), which requires a minimum of at least
two SAR probe calibration frequency points to support SAR measurements. To maintain SAR
measurement accuracy and to facilitate test reduction, the channels in U-NII-2C band above 5.65
GHz may be grouped with the 5.8 GHz channels in U-NII-3 or §15.247 band to enable two SAR
probe calibration frequency points to cover the bands, including the band gap channels. When band
gap channels are supported and the bands are not aggregated for SAR testing, band gap channels
