CompTIA Network+ (N10-009)Network ImplementationMedium
A network administrator is designing a new wireless deployment for a large university campus. The design requires high throughput and reliable connectivity across a wide outdoor area, including courtyards and pathways between buildings. Which of the following antenna types would be most suitable for providing focused, long-range coverage between specific points or across distinct outdoor zones?
- AOmnidirectional antenna
- BDipole antenna
- CYagi antenna
- DPatch antenna
Show answer & explanationAnswer & explanation
Correct answer: C. Yagi antenna
Yagi antennas are highly directional, making them ideal for long-distance point-to-point or point-to-multipoint connections where a focused beam of signal is required to cover specific outdoor zones or link distant buildings.
Why the other options are wrong
- A. Omnidirectional antennas provide 360-degree coverage, suitable for general indoor coverage or a central outdoor point, but not for focused long-range links.
- B. Dipole antennas are a basic type of omnidirectional antenna, offering general coverage, not focused long-range capabilities.
- D. Patch antennas are directional but typically offer broader coverage than Yagi antennas, often used for wall-mounted applications or smaller outdoor areas.
Yagi Antenna
A highly directional antenna used for long-distance, point-to-point or point-to-multipoint wireless communication, characterized by a series of parallel elements (director, driven element, reflector) on a boom.
- Provides high gain and a narrow beamwidth.
- Effective for overcoming distance and interference in focused directions.
- Requires careful alignment for optimal performance.
Memory trick: Think of a Yagi as a spotlight for your Wi-Fi signal, aiming it exactly where you need it.
