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

A.
All doors in the entire building should be open during the site survey.

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

C.
The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to only one floor above and one floor below.

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