Jackson needs to set up a dedicated Wi-Fi signal for his company's conference room using a point-to-point transmission. Which antenna should he use?

• A. Omnidirectional
• B. Unidirectional
• C. Dipole
• D. Parabolic

Answer: (B)

For a point-to-point Wi‑Fi link, you want to concentrate energy toward the other end to maximize signal strength and minimize interference from other directions. A unidirectional antenna does exactly that: it focuses the RF energy in a single direction, creating a stronger, more reliable link along the line of sight between the two points, such as across a conference room. Omnidirectional antennas spread power in all directions, which weakens the signal on the intended path and can pick up more interference. A dipole radiates fairly broad patterns and isn’t optimized for a fixed, targeted link. A parabolic antenna can provide very high gain and a very narrow beam, but it’s typically bulky and more than what’s needed for a standard conference-room setup; a simpler directional solution usually suffices to establish a dedicated link.
