3.Technical Standards
3.1 This specification is established in reference to the US FCC 47CFR Part 27 subpart M; the ROC National Standard CNS14336; and other international technical standards.
3.2 In consideration of consistency between this technical specification and the international technical standards, NCC will adhere to the pertinent modification as in the latest version of the technical standards in regard to test items, conformance requirement and test methods established in this specification.

4. Test Items and Conformance Requirement
4.1 Power Limitations:
4.1.1 Emission Power Limit:
(1) Conducted emission power shall not exceed 20W.
(2) The maximum effective isotropic radiated power (EIRP) shall comply with the rules of section 5.2.1 in the Technical Specification of Base Station for Wireless Broadband Access, and be tested during base station on -site evaluations.
4.1.2 Test Methods:
(1) When measuring the conducted emission power, a RMS-equivalent voltage instrument shall be used to measure it during any continuous transmission period; the setting of instrument shall be adjusted according to the instrument's response time, resolution bandwidth , and sensitivity to derive the correct conducted emission power.
(2) Testing channels are lowest, middle and highest channels; the emission models based on different operating bandwidth and the maximum modulation order shall be respectively tested.
4.2 Out-of-band emission limit:
4.2.1 Any emissions outside operating band shall be lower than the conducted emission power (P), measured in Watts; the attenuation outside the operating band and at the operating band edge shall be greater than 43 + 10 log (P) dB.
4.2.2 Test Method:
(1) Spectrum analyzer with the resolution bandwidth (RBW) set to above 1MHz shall be used while measuring.
(2) For the range from the channel band edge to 1.5 times of the emission bandwidth, a smaller resolution bandwidth (RBW) shall be used to obtain the correct measurement results of out-of-band radiated emission. The resolution bandwidth (RBW) shall be set to at least 1% of the emission bandwidth (26dB bandwidth).
(3) Testing channels are lowest, middle and highest channels; the emission models based on different operating bandwidth and the maximum modulation order shall be respectively tested.
4.3 Frequency Stability:
