a. The cellular standards listed only indicate the typical usages of that band in some countries: other standards
may also be used within those bands
b. Derate by 1.5 dB for temperatures higher than 55°C, or supply voltages lower than 3.0V. Derate by 3.0 dB for
supply voltages of lower than 2.7V, or supply voltages lower than 3.0V at temperatures higher than 55°C.
