20 MHz 0.65% (–43.7 dB) (nominal)
a. The signal level is within one range step of overload. The specification for floor do not include sig-
nal-to-noise impact which may decrease by increasing the number of carriers. The noise floor can be
estimated by DANL + 2.51 + 10
× log10(MeasBW), where DANL is the Display Averaged Noise
Level specification in dBm and MeasBW is the measurement bandwidth at the receiver in Hz.
b. Specifications apply when the carrier spacing is 600 kHz and the carrier power of each adjacent chan-
nel does not exceed the carrier power of the channel tested for EVM.
c. Specifications apply when the carrier spacing is 5 MHz and the carrier power of each adjacent channel
does not exceed the carrier power of the channel tested for EVM.
d. Specifications apply when the carrier spacing is the same as the signal bandwith and the carrier power
of each adjacent channel does not exceed
the carrier power of the channel tested for EVM.
e. In LTE FDD specifications, those values with % units are the specifications, while those with decibel
units, in parentheses, are conversion from the percentage units to decibels for reader convenience.
