Explanation
According to the Huawei documents and resources, the HLD phase is the high-level design phase of a WLAN project. It involves the following items:
Capacity planning: Determines the number and types of devices required for the WLAN network based on the customer's requirements and network scale.
Network design: Designs the network topology, IP addressing scheme, VLAN division, security policies, and other network parameters for the WLAN network.
Deployment planning: Plans the deployment sequence, schedule, resources, and risks for the WLAN project.
AP position planning is not involved in the HLD phase. It is part of the LLD phase, which is the low-level design phase of a WLAN project. It involves the detailed design of AP positions, antenna types, channel allocation, power adjustment, and other wireless parameters for the WLAN network. Therefore, C is the correct answer.
