Question 4

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 channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors B. The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey C. The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration D. 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

Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.
What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?

A. The use of cables longer than one meter in the RF system B. High output power at the transmitter and use of a low-gain antenna C. A Voltage Standing Wave Ratio (VSWR) of 1:1 D. An impedance mismatch between components in the RF system
