dBm/MHz

a. Derate by 1.5 dB for 55°C to 70°C.

b. Sensitivity degradations for alternate settings in MCS modes. MM: 0.5 dB drop, and SGI: 2 dB drop.

c. The cellular standard listed for each band indicates the type of modulation used to generate the interfering signal in that band

for the purpose of this test. It is not intended to indicate any specific usage of each band in any specific country.

d. The blocking levels are valid for channels 1 to 11. (For higher channels, the performance may be lower due to third harmonic

signals (3 × 824 MHz) falling within band.)

e. The minimum and maximum values shown have a 95% confidence level.
