6. Testing items and eligibility criteria for femtocell access point radio frequency equipment
6.1 Tests of this section are applicable to femtocell access points radio frequency equipment.
6.2 Occupied bandwidth: Shall be less than or equal to 5 MHz.
6.3 Maximum output power: In normal conditions, the rated output power limit is 20 dBm, and the maximum output power shall remain within +2.7dB and -2.7dB of the rated output power.
6.4 Frequency stability: Shall remain within ±0.25 ppm of the main frequency.
6.5 Spectrumemission mask: Shall comply with the spectrum emission mask shown in figure 1, the spectrum emission mask limit values prescribed in table 1 and the extra spectrum emission mask limit values prescribed in table 3.
6.6 Spurious emissions: Shall comply with the spurious emissions limit values prescribed in table 2.
6.7 Adjacent Channel Leakage power Ratio (ACLR):
6.7.1 Adjacent channel leakage power shall comply with 6.7.2 or 6.7.3, whichever is the higher.
6.7.2 ACLR limit: If the adjacent channel offset is 5 MHz, the ACLR limit is 45 dB. If the adjacent channel offset is 10 MHz, the ACLR limit is 50 dB.
6.7.3 Adjacent channel leakage power limit: the RRC filtered mean power centred on an adjacent channel frequency shall be less than or equal to -44.2dBm/3.84MHz.
6.8 Transmit intermodulation:
6.8.1 The transmitintermodulation level shall not exceed the spurious emissions limit values prescribed in table2.
6.8.2 Testing methods: Inject modulated interference signal into the antenna connector at a power level of 30 dB lower than main signal. The interference frequency shall be offset ±5MHz, ±10MHz and ±15MHz from the main signal. The interference frequency that are outside of any downlink application band are excluded.
6.9 Output power for adjacent channel protection: According to the setting of table 4, shall comply with the limit values prescribed in table 5. The output power shall remain within±2.7 dB of the limit values in table 5.
