Question 1

What type of antenna radiates power equally in all horizontal directions while concentrating it in the vertical plane?

Accepted Answer

Omni-directional antenna

Answer

Omni-directional antennas radiate energy equally in all azimuthal directions while providing some vertical gain by compressing the beam.

Question 2

Which connector type is most commonly found on consumer-grade WLAN access points for external antenna attachment?

Accepted Answer

RP-SMA

Answer

Reverse Polarity SMA (RP-SMA) connectors are the industry standard on consumer and prosumer WLAN equipment for antenna connections.

Question 3

A wireless bridge link requires covering 3 miles between two buildings. Which antenna type is most appropriate?

Accepted Answer

High-gain directional antenna

Answer

High-gain directional antennas focus energy toward a specific point, making them ideal for long-distance point-to-point links.

Question 4

What does EIRP stand for in the context of wireless networking?

Accepted Answer

Effective Isotropic Radiated Power

Answer

EIRP (Effective Isotropic Radiated Power) is the total power radiated by a system compared to an isotropic radiator, combining transmit power and antenna gain.

Question 5

When an antenna gain is listed as 6 dBi, what does the 'i' refer to?

Accepted Answer

Isotropic radiator reference

Answer

The 'i' in dBi indicates the antenna gain is measured relative to a theoretical isotropic radiator that radiates equally in all directions.
