COMPUTER FUNDAMENTALS

Detailed explanation-1: -Directional antennas send and receive signals in one direction only, usually in a tightly focused, very narrow beam. The signal pattern from a directional antenna has a cigar shape, and looks the same from the top as from the sides. This shape is referred to as a lobe.

Detailed explanation-2: -Directional antenna Was this answer helpful?

Detailed explanation-3: -The cochannel interference can be reduced by using directional antenna. This means that each cell is divided into three or six sectors and uses three or six directional antennas at a base station. Each sector is assigned a set of frequencies (channels).

Detailed explanation-4: -RF and microwave directional antennas are used in many different applications across multiple industries. Some directional antenna common uses include cellular networks, base stations, land mobile radio (LMR) applications, GPS systems, SCADA, critical response communication and many others.

Detailed explanation-5: -Directional antennas: The benefit is that the signal from the target direction is improved through the directivity gain (like amplification). The gain from other directions is reduced as a result and hence the interference (unwanted signals) is suppressed.
