When performing a validation survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with five floors, what aspect should you, as the surveyor, keep in mind?

A. The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration

B. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors

C. The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible

D. The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey
