a. Derate by 1.5 dB for –30 °C to –10°C and 55°C to 85°C.
b. 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.
c. For 65 Mbps, the size is 4096.
d. The minimum and maximum values shown have a 95% confidence level.
