A. B. C. D.

B.

The letter P in the designation of the AIR-CAP3502P AP stands for "plenum-rated". This means that the AP has been designed and tested to meet specific safety requirements for use in plenum spaces, which are areas in a building used for air circulation, such as above suspended ceilings or below raised floors.

Plenum-rated equipment must meet certain fire safety standards to minimize the risk of fire spreading through air ducts and ventilation systems. Plenum-rated devices are usually constructed with materials that are less likely to ignite and produce harmful smoke or gases.

Therefore, answer C is correct: the AP can be used in plenum applications. Answer A is incorrect because there is no such thing as the IEEE 802.11p (WAVE) wireless standard. Answer B is incorrect because there is no requirement for professional installation of the AIR-CAP3502P AP. Finally, answer D is incorrect because the designation P does not indicate compatibility with polarization type antennae.
