This document presents the third part of a comprehensive test report focusing on the occupied bandwidth of various LTE bands. The report details the measurements and analysis conducted to assess the bandwidth characteristics under different modulation schemes and channel configurations. The tests were performed using a Keysight Spectrum Analyzer, ensuring accurate and reliable data acquisition.
The report covers LTE bands such as Band7, Band12, and Band25, with varying channel bandwidths including 1.4MHz, 3MHz, 5MHz, and 10MHz. Different modulation schemes like QPSK, 16QAM, and 64QAM were employed to evaluate the impact on occupied bandwidth. The results are presented in a clear and concise manner, with graphical representations of the spectrum analyzer measurements. The report provides valuable insights into the bandwidth performance of LTE systems under diverse operating conditions.
The test results include key parameters such as occupied bandwidth, transmit frequency error, and x dB bandwidth. These parameters are crucial for ensuring compliance with regulatory requirements and optimizing the performance of LTE networks. The report serves as a valuable resource for engineers and researchers involved in the design, testing, and deployment of LTE systems.
