On-tower preparations mainly include selecting the azimuth angle and height for pole mounting based on the engineer experience .

The statement is incorrect. The selection of the antenna's azimuth angle and height are critical parameters determined during the network planning and design phase, not during on-tower preparations. This pre-installation phase uses radio network planning software and is based on detailed engineering surveys, coverage objectives, and capacity requirements. The results are finalized in a formal engineering design document. The on-tower preparation and installation phase involves the field engineer's task of precisely implementing the specifications laid out in this pre-approved design document, not selecting these parameters based on personal experience. While experience is valuable for troubleshooting and execution, it does not replace the formal engineering design for fundamental parameters like azimuth and height.

The option "True" is incorrect because it misrepresents the standard workflow for cellular site deployment. It incorrectly assigns a core design function (selecting azimuth and height) to the on-site implementation phase (on-tower preparations) and wrongly attributes the basis for this decision to "engineer experience" instead of the formal, data-driven network design plan.

1. Official Vendor Documentation: According to the Huawei 5G RAN Network Planning Guide, the antenna's height, azimuth, and downtilt are fundamental outputs of the radio network planning and simulation process. This process aims to optimize coverage and minimize interference based on topographical data and user density models. The final parameters are recorded in the network design documents provided to the installation team. (Reference: Huawei 5G RAN Network Planning Guide, Chapter 4: Detailed Network Planning, Section 4.3: Antenna System Parameter Planning).

2. Official Vendor Documentation: The Huawei 5G Base Station Installation Guide specifies that a primary step during pre-installation checks is to verify that the planned installation positions on the tower correspond to the engineering design drawings. The guide emphasizes adherence to the specified azimuth and height from the design documents, with any deviation requiring a formal change request process, not an on-the-spot decision by the field engineer. (Reference: Huawei 5G Base Station Installation Guide, Chapter 2: Installation Preparations, Section 2.2: Verifying Engineering Design).

3. University Courseware: In wireless communication engineering curricula, the cellular network design lifecycle is taught as a structured process. The initial phases include planning and design, where parameters like cell site location, antenna height, and orientation (azimuth) are determined through simulation to meet Grade of Service (GoS) requirements. The subsequent implementation phase is about executing this plan. (Reference: Courseware on "Wireless Communication Systems," Module on 'Cellular System Design Principles', Stanford University).
