An engineer must perform a pre deployment site survey. For a new building in a high-security area. The design must provide a primary signal RSSI of -65 dBM for the clients. Which two requirements…

Site access is a logistical prerequisite for physically conducting the survey, not an RF design parameter that influences signal coverage or RSSI calculations.

The AP model determines transmit power, antenna gain, and radiation pattern, all of which directly affect the achievable RSSI at the client distance; different AP models produce different signal levels under identical conditions.

The WLC model governs centralized management, policy enforcement, and client capacity but does not influence the RF signal strength or coverage area of deployed APs.

HVAC access is a physical installation consideration for cable routing, not a factor in RF coverage design or RSSI target planning.

The number of clients drives AP density requirements - more clients per area requires more APs and smaller cell sizes, which determines how coverage must be arranged to maintain -65 dBm throughout the space.
