A wireless engineer is designing a wireless network for a campus. Which two parameters can have a negative effect on the Wi-Fi coverage of an access point? (Choose two.)

The correct answer is B. surrounding area C. wireless channels. Two factors that directly and negatively impact Wi-Fi coverage are: (B) the surrounding area-physical obstacles such as walls, floors, furniture, and building materials (concrete, metal) absorb and reflect RF signals, reducing effective range and creating dead zones; and (C)…

Explanation

Two factors that directly and negatively impact Wi-Fi coverage are: (B) the surrounding area-physical obstacles such as walls, floors, furniture, and building materials (concrete, metal) absorb and reflect RF signals, reducing effective range and creating dead zones; and (C) wireless channels-poor channel planning causes co-channel interference (multiple APs on the same channel within range), which degrades signal quality and reduces usable coverage. Authentication (A) and wireless encryption (D) add protocol overhead but do not meaningfully reduce RF coverage range. Antenna type (E) influences coverage shape and can improve or focus coverage depending on design, but choosing an appropriate antenna is a design tool, not inherently negative.
