4.5     Out-of-Band Emissions Measurement
4.5.1     Limits of Out-of-Band Emissions Measurement

According to FCC 27.53(m)(4)&(6) specified that power of any emission outside of the channel edge must be
attenuated below the transmitting power (P) by a factor shall be not less than 40 + 10 log (P) dB on all
frequencies between the channel edge and 5 megahertz from the channel edge, 43 + 10 log (P) dB on all
frequencies between 5 megahertz and X megahertz from the channel edge, and 55 + 10 log (P) dB on all
frequencies more than X megahertz from the channel edge, where X is the greater of 6 megahertz or the
actual emission bandwidth. In addition, the attenuation factor shall not be less that 43 + 10 log (P) dB on all
frequencies between 2490.5 MHz and 2496 MHz and 55 + 10 log (P) dB at or below 2490.5 MHz. In the 1
MHz bands immediately outside and adjacent to the frequency block a resolution bandwidth of at least two
percent may be employed, except when the 1 megahertz band is 2495-2496 MHz, in which case a resolution
bandwidth of at least one percent may be employed.

                                                                           Pad
                                                 EUT




4.5.3     Test Procedures

a. The EUT was set up for the maximum peak power with LTE link data modulation. The power was
      measured with R&S Spectrum Analyzer. All measurements were done at 2 channels (low and high
      operational frequency range.).
b. The out-of-band emissions measurement used the power splitter via EUT RF power connector between
      simulation base station and spectrum analyzer.
c. Record the max. trace plot into the test report.
