What are the disadvantages microwave communication?
attenuation due to atmospheric conditions.
What is attenuation network?
Attenuation is a measure of how much loss a signal experiences when it travels down a communication medium( loss as heat, absorbed by communication medium).It is mesured in decibels Attenuation is a term that refers to any reduction in the strength of a signal, when transmitting over a long dinstance. Attenuation occurs with any type of signal, whether digital or analog. It is also called loss of signals, The extent of attenuation is usually expressed in units called decibels (dBs).
What does attenuation mean in data communication?
it means loss of signal as distance increase July
What are the advantages of radar communication?
radar communication isfaster and has less attenuation(loss of signals).it is wireless so more preferred over other modes of communication
How does water affect the travel of radio frequency?
Water affects the travel of radio frequency in terms of attenuation. For example, sea water has high attenuation, causing communication hardly possible.
What is attenuation problem?
The attenuation problem refers to the loss of signal strength as it travels through a medium, which can lead to degraded communication quality or data loss in various systems, such as telecommunications and networking. This phenomenon can occur due to factors like distance, interference, and environmental conditions. In optical fibers, for instance, attenuation affects the clarity and distance over which signals can be transmitted effectively. Managing attenuation is crucial for ensuring reliable communication and maintaining signal integrity.
Where does attenuation occur?
Attenuation typically occurs in processes involving the weakening or reduction of a signal's strength, intensity, or energy. In communication systems, attenuation can happen in transmission lines, optical fibers, or wireless channels, leading to signal loss or degradation over distance. It is essential to account for attenuation to maintain signal quality and integrity in various applications.
In most microwave communication link rain drop attenuation is caused due to?
Due to multiple reflections
What are the differences between low attenuation and high attenuation in terms of signal strength in a communication system?
Low attenuation refers to a situation where the signal strength remains strong over long distances, resulting in minimal loss of signal quality. High attenuation, on the other hand, indicates a significant decrease in signal strength over distance, leading to potential loss of signal quality.
Many network hubs incorporate repeaters or amplifiers to regenerate signals so that attenuation of the signal does not occur?
As a rule a hub does not contain a repeater. Amplifiers would be used in analog communication, not digital communication. Attenuation is a process that occurs all the time in networks; you would place a repeater in an area where the attenuation would cause the signal to degrade to the point where it wouldn't be usable. You would want the repeater to be placed before that point.
What are the disadvantage of ultrasonic wave communicaton?
Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.
What is the impact of absorptive attenuation on the transmission of signals through a medium?
Absorptive attenuation reduces the strength of signals as they travel through a medium, leading to a decrease in the transmission of information. This can result in distortion or loss of the signal, affecting the quality and reliability of communication.
